Just received my HP compressor yesterday. Decided this morning to just see if it runs. Had both bleed screws open but the darn thing wouldn't turn over at all. It just buzzes as the motor tries to turn the compressor part. Already contacted vendor and will see what he says. Very disappointed!!
-
If there is not sufficient amperage available on the circuit that you are plugged in to, this can happen. I'd try a different outlet, preferably one with little to no other additional load. Also, make sure that you are plugged in directly to the outlet, extension cords are a no-no.
If you still have issues I would suspect the capacitor but I have heard of at least one person who's machine had temporarily "froze". If i remember correctly they unplugged and manually turned the crank a little. Plugged it back in and all was good.
-
Yep, reach into the fan shroud on the motor and 'goose' that fan a bit. Use something other than a screwdriver. Like maybe a popsicle stick.
-
I'll give both suggestion a try this evening after it cooled off some. It triple dig out there right now.
-
Not saying all will have same results but, I run mine on a 100' construction cord with a light and water pump plugged into a 3way. The cord is then plugged into the same outside outlet as our 5cf freezer. I've yet to have an issue.... oh wait... it did smoke a power switch once but I think that was a weak switch or loose connection... I replaced it with no further problem.
-
I've had similar issues and solved them by spinning the fan as noted by avator.
-
Plugged it into a wall outlet and botta boom it runs!!! I guess the cord I was plugging into had just to small a gage wire in it. Need to make a 12 gage 6 ft extension cord for it with 2 outlets on the end. YEA!!!!!!
-
Glad you got it!
-
Good call Garry.
-
Well, I filled my rifle for the first time, almost. I got up to about 3600 to 3700 psi and the burst disk popped! Hey Bill, have you ever had that problem with your pump? That's about where I'll be filling most of the time but wanted to take it up to 4000 to see if it still leaked.

$56 for vevor compressor? ??? ?
WOW! If that is a NEW Yong Heng at THAT price... I may have to get one and look at some more PCP's other than the Nova Freedom I have now!
Of course, that old saying "if it sounds too good to be true..." keeps coming to mind. :-[ ::) 8)

Nope... like I said before... I only fill guns.
-
Well... OK shoot me, I pulled the trigger on the $57 Yong Heng.
Dang... I knew I got too close to that rabbit hole... :'(
I sure hope I don't regret it.
-
I put one in the cart but, I couldn't make my finger push the buy button. It just kept curling up on me.

Yeah, I know what you mean... but it is too late for me.
Fingers crossed!
Also, first time I have EVER ordered ANYTHING off of eBay and depending on how it goes, may be the last time!
The seller did seem to have a decently high rating... for what that is worth...
We'll see.

No FB yet from anyone who bought the compressor. The seller has 2 negatives out of about 100 transactions- both for items never arriving. One says tracking shows the item was delivered, buyer says not delivered- could be buyer scam or stolen package. The other negative FB indicates the seller didn't respond to the non delivery and besides no FB on the compressors it's this supposed lack of communication by the seller that would be my concern.

Estimated delivery June 25, but I am not holding my breath. If all else fails, my CC company is very good about taking care of charges that are not fulfilled. Been there and done that a couple of times.
The thing is, with the Nova Freedom I really did not need this compressor! Of course, NOW, I HAVE to buy a better PCP! Or 2 or 3! (chuckle)
Seriously... I will be thinking about another PCP if this compressor works out OK and I will be looking for suggestions. Of course, I bought a Nova Freedom and a $57 compressor, so you kind of get the feel for my price range. ::) ;) 8)

I read the negs. Those items appear to have come from China. The compressor info states it ships from Cali. I'm thinking the 10 day shipping to my zip would be due to the fact that it will be shipped ground because of weight/cost. It is pretty crazy when you consider shipping is probably half of the total cost.

I saw that...
Item location: Sacramento, California, United States
But I wonder...
If it does get here by June 25, then I will say it definitely was NOT shipped from China! LOL!
And as far as I can tell the seller IS in China. But I am not really familiar with eBay, so I may have gotten that wrong.

I sent the seller a message asking if..
The Yong Heng was a legit deal.
$56.99 and free shipping?
Shipped from USA?
We'll see if he responds.
-
Says it ships FedEx Ground or FedEx Home Delivery. Home Delivery means it won't get transfered to USPS... like SmartPost.

I guess that is what I should have done before pulling the trigger...
Let me know if you hear back from him.
Thanks!

The messages go through Ebay so they get a read on it as well.
They monitor to insured that you are not making a side deal with the seller and cutting them out.

Yeah, I figured that, so I appreciate that you sent a message.
Thank you!
In any case, we'll see. Either it is one heck of a deal or I am going to have to go through a small hassle to get my money back.
I have learned not to sweat the small stuff.

It's worth a shot for about the cost of dinner out for two.
I make it a rule never to gamble with what I can't afford to lose.

If I thought I would lose $57 I would not have pulled the trigger and I agree with that attitude.
That is probably why I have never been to Tunica, Mississippi. (grin)
-
I hope you get what you ordered as that's a smoking deal. The unit pictured is the same hard pack model I have and it has run well for me. Unless you're just gonna fill guns directly would recommend adding one of the black ebay filters for a second layer of moisture protection. I'll be watching this one when you all receive your orders.

The only PCP I have right now is the Nova Freedom in .177, so I don't really need the Yong Heng, but I bought in anticipation of buying another PCP sometime in the future. And at this point, I don't plan on buying a tank. So, filling a PCP rifle will be the main purpose. I only kill rodents on my property and I almost only shoot from within my house, so I don't need portability with a new PCP and I already have the Freedom for that anyway.
I think there are 4 confirmed orders for the same thing here on the forum, so you will definitely hear from at least one of us sooner or later! (chuckle)
Now where is my bailing bucket? LOL!
-
I just bought one also. I know , I know I already have one but it might be going back. I just got this message to my inquiry about the burst disk failing and only 3600-3700 psi and this was their reply. "We have asked the manufacturer
They said already the pressure of 25-27mpa, already high enough pressure, the rupture disk is broken and can be replaced again" It's advertised as a 30 mpa pump! I'm going to try it one more time and if bursts again we gona have us a problem. LOL

Dang! I hope this boat doesn't capsize! lol!
Welcome aboard, grab an oar and a bailing bucket! (grin)
I think there are about 6 or more in the boat now. Not really sure anymore.

Well, we'll see? If a deal is too good to be true it just might be.

Yep... I would have replied sooner but...
I had to give my cat a flea bath/shower... don't ask...
She doesn't like water or soap and I am exhausted!
-
I find putting the cat in the toilet, close the lid real fast then just flush it about 10 or 20 times. They come out clean as a whistle and smelling like air freshener. LOL For those who might be offended it's a joke. I have 11 dogs and 1 cat and she has all of the dogs scared of her. Even my German Shepard. lol
Well, this time I got all of the way to 3900 before the disk blew.
-
Weak discs?
-
Not sure whats happening. I'm not exactly sure what the discs are suppose to look like when the fail but these look like they just folded over instead of bursting.
-
Never experienced a burst disc so I can't help ya there.

Could it be the gauge is reading low?
-
The gage if anything is reading high. The gage read 4200 but the rifle only read 3900 and seeings how they're both CiCom gauges......
-

How high do you fill your rifles
-
Never experienced a burst disc so I can't help ya there.
How high do you fill your rifles
When hand pumping with the on board pump.. 3k
For testing, sighting in, plinking and using the tank or compressor.. 3600
No issues from either.
I do have a small overnight leak but I can live with that. I begin my shooting session by filling with a tank to 3k then begin my routine... 10 shots.. 17 strokes back to 3k.
-
Thanks Bill. I took the burst disk holder apart and found that the third disk I installed is bulging and I've not even got to 4k with that one.

?????

NT = no text.
I started to post a reply and changed my mind for one reason or another.
-
Could somebody measure the thickness of the burst disk for either the vevor or the yong heng. I measured the ones that came with my pump and they came out to .0095 thou. All of the burst disks on ali said they are 3.5mm thick which is .0138 which could be the problem with the burst disks blowing at no more than 4K psi. I've had 4 blow at anywhere between 3500 and 4000 psi. I've already sent a message to the seller telling him the item is NOT as described so we'll see what happens.

I found the second stage piston rings for the vevor. https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.6.2.34474c4dTu9ee4&orderId=103371311705426&productId=32691690417 (https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.6.2.34474c4dTu9ee4&orderId=103371311705426&productId=32691690417)

Well, the seller is refunding me $15 which will just about cover getting the right burst disks and some second stage rings.

Those are not like the high pressure seals in my Vevor.

Well they match the ones that came with my pump.

That link worked. Thanks!
No problem. Well, I did get the seller to refund $15 because of the burst disk problem. I think the ones that came with the pump were to thin and giving way to easily. As soon as that slow boat from china arrives at my PO box I'll switch out the disk and give it a try. I really don't need to go that high in pressure but when you pay for some thing to a certain thing even if you don't need all of it's capability it needs to perform to that level. I have a CBR1100XX blackbird and it's suppose to be able to go 177 mph, now there's no way in heck I'll ever go that fast but it darn well should be able to in my book. I've taken it up to 155 mph and felt like I was going to get blown off the back even with the fairing. lol Never again!!

There is a store on Aliexpress called Antlers Online. You have to message a person there (I downloaded the app on phone) and send them a pic of what you want. I got a few for my Vevor that way.

I tried to find antlers online but no joy.

Just found the burst disk for the air venture compressor is the same as the one on the vevor. ! disk is $4.95 lol https://www.pyramydair.com/product/av-4500-electric-air-compressor-burst-disk?a=8326 (https://www.pyramydair.com/product/av-4500-electric-air-compressor-burst-disk?a=8326)
But I might just have to buy one if the last 2 I have burst before my order gets here on the slow boat from china.

Those 2nd stage piston rings sold by Pyramyd Air are nothing like what is used on the Vevor compressor.

Anybody have a problem with their Vevor overheating while just running but not pumping any air? The darn thing went up to 63C in just 10 min. with both beeld valves wide open. I'm trying to see if I can get it to start a little easier as right now it's a real pain. I've got it plugged into the same outlet I run my big devilbiss oilless air compressor from but of course not at the same time and it has no problems starting or reaching 125 psi. I never did the 20 min. run not under load that I've read is recommended for a new compressor like my vevor so figured maybe that is the problem. It always has been hard to get to start since I received it.
Oh, forgot to say it started at 26C and water fresh out of the tap.
-
Look at your water pump. There is a flow adjustment. It looks like the grill of a fan. It turns to open for more flow.
-
It's wide open and it's also a different pump with more flow. I would think that with no flow it wouldn't be a problem with heat.
-

My compressor is not a Vevor but a YH. What yours is experiencing are the telltale signs before mine failed.
It goes without saying that you should eliminate as many other possibilities first before tearing into it.
Keep us posted if you would.
-
Did you fill tanks with it or guns only?
-
Only my liberty. I've only had it 3 or 4 months and most of that time I did not use it because it kept blowing the burst disks. I think the reason it kept blowing the disks is bronze filter in the fill probe was plugged. It's always had a hard time starting since new.
-
So now that what's causing it is it fixed?
-
I drilled out the probe to remove the filter but have not had the chance to try it as Duy has my receiver to mod and he's as busy as a 1 legged man in a butt kicking contest. The burst disks also were on the thin side.

PM sent.... lol

How about since it does not have a load on it, it is running at higher rpm and causing extra friction heat too... I know my clone after a many fills, the temperature evened out and ran a acceptable temperature..

My replacement second stage seal just let go, got a bit too hot.
Turned and polished one out of peek, much higher working temperature, abrasion resistance... than the original what appears to be acetal. Turned a check valve cone while I was at it.
Amazing result, it took 230cc cylinder from 1500 to 3000 in 25 secs with a large volume coalescing filter. Best yet. Temp didn't even have a chance to rise above 57c.
For twenty minutes of work we will see how long it lasts.

Now this shows some real promise. Could be the answer to one of the weaker parts of of many of these small compressors.
Go PEEK GO!

Only thing I'm worried about is wear on the second stage cylinder. The original second stage ring is soft and wouldn't wear the cylinder near as much. I've bought 6 of the second stage rings for less than $8 delivered though it did take 3 weeks to arrive.

How long did your second stage rings last before you had to replace them?
Do you have an hour meter?
-
No hour meter attached. Just swapping seals and check valves as needed, 3 provided seals took me 15 months of use. Hour meter would let me know how much work was achieved, but it is no guarantee as to how long a seal will last because an overheat could wear out a new seal in minutes. Keeping it very cool is number 1... or use material with higher working temperatures.
Peek is twice as good at deflection temperature to 250°C vs. Acetal homo 125°C. Which is probably why the recommended working temp limit of 65-75°C at the alum collar. The piston seal temp would obviously be much higher since it's the part generating the pressure. Peek doubles the limit and with half the thermal expansion.
The Vevor only has 1 second stage piston seal, unlike the Yong Heng or Tuxing multiple ring piston seals. Vevor is much more susceptible to heat failure with the single seal. Also much easier to fab and replace a single seal, removable without removing the piston rod, just unscrew from the top. ;)
So I am playing to the strengths of the configuration and strengthening a weak link. Which usually makes something else break... It may induce more wear to the steel sleeve, but it will definitely resist the heat.
Worth a try. I will let you know if it all goes to héll, but it may take a while which is what I'm hoping for.

Yep that is exactly what happens.....ya move the problem to next weakest link.
But like you said it's worth a try.
Nothing ventured nothing gained.
I've got a new complete head coming in. Second stage went after 11 hours/year of use. A washer that holds the seals on the 2nd stage broke in half and the output air pressure dropped to like a 1/3. Never had an overheat problem at least according to the temp meter on the YH.
I'll rebuild the orginal an use it as a spare.

Well, the new burst disks I got from china are still popping at less than 3K psi when I filled my Liberty this morning. I just did a fill on my Liberty again this afternoon using 2 burst disks instead of one and it pressurized the Liberty to 3K and of course didn't pop. I'm watching the pressures the whole time as I'm only filling up my rifle. I did order some more from a different vender in china that claims the disks are 3.5 mm not the 2,8mm that the last ones ended up being. I got a feeling that the burst disks I bought before are made of copper instead of brass. I'm not sure what the pressure difference would be between the 2 metals. The compressor is suppose to be able to fill to 4500 psi darn it!!!!!

You could use some aluminum can also..

On my first tuxing I had the same problem. I doubled my disks and they never popped after. I'd just be cautious that whatever your filling has an accurate gauge because the cheapie Chinese ones on the compressors and various other gun gauges can be off by quite a lot.
If you want to change the compressor gauge, I know Wika gauges are American made and of good quality. You can get a 5k psi gauge with a 1.6% accuracy for ~$30 and would just need an adapter to thread it into the compressor head.

Well, I tried to fill the 66 cuft scba tank I just got with my vevor and after having to shut it down due to high temps 4 or 5 times managed to get it all of the way up to 500 psi. YEA!! I had the water temp going into the compressor down in the low 20C range and it still couldn't keep it's cool. PITA!!! Will keep at it but this is going to take a long time I fear. lol So tempted to pull the trigger on a F10 shoebox. I've got a commercial grade oil less compressor that will more than supply enough pressure to the F10. If I wan't in the process of trying to move out of Kali I would but may need the money for moving, the new house,etc, etc, etc.Think Youl Brenner in the king and I.

Buy a Booster from Altaros its quiet fills fast and has no maintenance as long as theres a good water filter before it.

Peek seals working great, still early for long term comparison.
Just filled my 3L carbon bottle to 4300 Psi starting at 2800. Took less than fifteen minutes and stayed under 55C with ice in the bucket. Second stage really takes a lot of stress going over 4000, but I’m stress testing the peek, not babying it. It was a couple of similar fills that toasted one of my original seals.
-
I put ice in the 5 gal bucket and it was almost melted by the time I started to run the compressor. lol Temp was in the mid 90's which is a big part of the problem.
-
Well, I went ahead and changed out the second stage ring not that it really needed it but thought it had failed when I pumped up my Liberty to 4K psi to do a shot string. Turned out a O ring in the female coupler screwed up and started to leak. Man, what a PITA!!! The second stage piston was loose in the piston and I couldn't get the screw out to change the ring. Ended up taking the complete top end off of the compressor, fighting with the piston pin c clip and then finally getting it out clamped the second stage piston between to pieces of wood tightened the screw under the piston head and finally was able to get the screw out of the second stage ring. I actually had to use a impact driver to get the darn thing loose. Then when I reinstalled the screw I had a heck of a time getting it tight enough so the screw head wouldn't hit the head. Then the compressor wouldn't turn over at all. Had to use a screw driver to turn the fan so the motor had a little run up before stopping. Did that about 10 times before it would finally run. I even ran it for a few min. with out the head so the ring had a chance to loosen up a little. I gotta tell you that all of the parts looked real good with no bad wear marks to be found. The rod looked nice and smooth with no gualling. The piston still had the machining marks from when it was made so hopefully it means it's going to last awhile.
I do have to say that it runs a lot quieter than it did. The second stage piston wasn't all that loose but I guess with as much pressure that was pushing on it was enough.
-
I don't know what broke loose in my compressor but it was plugging up the output where the hose attaches. I'd start it up and when I closed the bleed valves it would shoot up to 4K psi so quick it wasn't funny. I took the hose off and started up the compressor to see what was happening. I had just closed the high pressure bleed valve when the white plastic washer that the hose seals against shot out and hit my hand right where the first knuckle of my right index finger is aka trigger finger. Darn thing drew blood too. OUCH!!!! Have no idea what was causing the blockage but when I replaced the white plastic sealing ring with one from the spare parts and screwed in the hose it worked just fine. It fills my rifle up a lot faster than it did before I replaced the second stage ring. I wonder if what ever plugged up the out let was causing a restriction of the airflow from where ever it broke loose from?
-
Sounds like maybe you have been closing the bleeder too tightly and mushed the white seal. You should be fine now, just don't crank it closed so hard, just enough for it to not leak.
-
Thing is is, it didn't give me problems until after I had the complete top end off and reinstalled.
-
I believe I remember reading about the white washer on the fill whip being crushed too tight. The hole when crushed closes and will reduce flow and can increase pressure due to a total or partial blockage? Maybe
-

Something may have been dislodged during the repair and plugged it up.. I'm just taking stabs at the cause here.

That's what I'm thinking. The hole in it isn't very large and could be plugged easily.
-
Got a new one for ya'lls. lol The low pressure vent screw keeps backing out while I'm filling my rifle. It's gotten to the point I'm holding the screw to keep it in place until I'm done filling. Anybody had that problem? The rifle is filling just fine when the pressure filling the rifle drops almost 1K psi. When it first happened I'm thinking now what's gone wrong???
-
I put a spring behind it to keep some tension on both the low and high screw.
Hasn't moved since.
-
Good advice there Matt.
-
I've crushed a couple white washers before. I just take a small drill bit and drill the hole back out while it's installed.
