Chinese compressor turning off

[AGEnthused2]

As this is a Chinese compressor I expect that many cheap parts were used, so has anyone else had their compressor turn off while pumping, it normally happens every 5-8 minutes while filling my tanks, I don’t have to fill them often.
If there is a part that can be swapped out to a better quality one then I could run the compressor for the 20 minutes that it normally takes to fill.
Basically looking for advice, I don’t run the water pump off the compressor, it’s plugged into the wall outlet.
So which part can be replaced to take care of this?
I just click the button on the compressor to reset and let the compressor cool off for a few minutes and then run it again.

Need to know what kind. On my yong heng,,,there is no place to run the water pump off the compressor. So must be something different. Possibly built into the machine to prevent over heating.

The brand is tuxing, I stay close to my compressor when it’s running, but since it’s a bad practice to start the compressor with a load, I have to close my tank and open all my bleeder valves. Just annoying to do.

Yes, it would be best to have some pictures and more information.

What temperature is the pump shutting off? The extreme operating temperature is 65C to 70C. The compressor will overheat and shut off at 75C.
Have you replaced the water pump with one having a higher flow rate?
Have you tried adding ice to the water? And/or wrapping the water pipes in wet cloths?
Try a fan blowing on the water pipes?

Are you running the pump off a power strip or a wall plug? The manufacturer recommends the pump be run on a 20 amp breaker, not on a power strip. 

The troubleshooting table in the manual lists three possible problems for over heating

1. Wrong fan rotary direction. (should be blowing in the direction to cool the water)
2. Bad ventilation. (move the compressor to better ventilation)
3. Long time running.

As for filling tanks, the manual advises tanks no more than 3 liters to 4500PSI, 30MPa.

I’ve changed the temperature gauge to a Fahrenheit one, the temp is 80 degrees F.
Compressor is on a 20amp breaker plugged directly into the wall.
The tanks I fill are filled 500 psi at a time. With several hour long breaks between.
I don’t believe it’s a true overheating issue, a cheap part issue.
The tuxing compressor has a large cooling jacket, larger than any Yong Heng.

I don't have your compressor so this is general guess. Some motor windings have a small thermal breaker installed IN the winding to protect them from overheating. If present, that thermal breaker is either damaged or it is accurate and your motor windings really ARE getting too hot for some other reason.

Maybe try to use a separate fan to blow more air through the motor?

I think an extra fan would be good, I already have a replacement for when this compressor finally dies.
