Common problems in maintenance

Solution for universal JUN-AIR compressor failure to start.
a) There is no main power supply. Check the fuse and shake the head.
b) There is looseness and damage in the electrical connection
c) Capacitor malfunction.
d) Due to overheating, the thermal protection has turned off the pump. When the pump cools down to an appropriate temperature, it will automatically start.
e) The compressor has not unloaded the load and there is reverse pressure on the piston. Ensure to unload the load after each shutdown.
d) The pump has been locked.
e) The pressure in the storage tank is too high to trigger the pressure switch. This pressure switch can only turn on the circuit when the pressure drops to the preset starting value. It can release gas from the storage tank.
If the vacuum configuration has a gas storage tank and a vacuum switch.
~h) The internal vacuum of the gas storage cylinder. When the true degree reaches the preset minimum vacuum level on the vacuum switch, the vacuum pump will start. You can open the intake of the air storage cylinder.
　

JUN-AIR compressor does not start and emits buzzing noise
{Cannot start due to high pressure}
a) The check valve is leaking. Discover if there is a leak from the valve by dismantling and cleaning the diversion pipe. If so, clean or replace e
　

3. The vacuum pump can work, but it cannot fully exhaust the air
a) Check the gasket of the piston and replace it if necessary
b) Valve plate failure. Please
c) Air intake failure a, please replace a
If the vacuum pump is equipped with the wrong cylinder and vacuum gauge:
d) The vacuum filter is blocked by the wall. Please clean or replace the filter element.
e) There is a leak in the filter, hose, or equipment. Closing the intake may locate the leakage point.
f) Vacuum gauge failure. Please replace.
　

The JUN-AIR compressor is working, but the pressure will not increase.
a) The filter is blocked at the gas end. Please replace.
b) Leakage occurs in filters, conduits, or inflation equipment. It can be removed from the main equipment by using soapy water for testing. Reduce the pressure to no more than 1 Pa.
c) Check the piston gasket. If necessary, please replace a
d) The intake and exhaust photography failed.
e) The check valve failed due to flow restriction.
f) Leakage occurs in filters, conduits, or inflation equipment. It can be removed from the main equipment by using soapy water for testing. Reduce the pressure to no more than 1 Pa.
　

5. The compressor makes a lot of noise
a) Dust accumulation or failure inside the anti roll valve. Please clean and replace
　

6) The motor generates high temperature
a) Leakage.
b) The vacuum filter is clogged with cold.
c) The ambient temperature is too high. If the vacuum pump is installed in a box, please ensure sufficient ventilation.
d) Overload. Please ensure the correct type of compressor is selected for the workload.
　

When the compressor starts, no air is discharged
a) Leakage.
　

8. No vacuum is generated when the vacuum pump is started
a) Leakage.
　

9. The vacuum pump starts and stops more frequently than usual
⑧ Leakage.
　

10. Vacuum installation does not start when the vacuum degree is at its lowest, and does not start when the vacuum is stopped

停止。
The following points only apply to products with vacuum gauges
a) Vacuum switch failure. Please replace.
b) The vacuum switch was not adjusted correctly. Please adjust correctly.

The JUN-AIR compressor did not start at the starting pressure or did not stop at the maximum pressure-
Pressure switch failure. Please replace.
　

12. Testing of Check Valve
·Once a year
·Turn off the compressor by turning off the main switch and unplugging the plug,
Pull out the circular ring at the end of the safety valve
　

JUN-AIR has a lot of noise!
a) Reduce the pressure to 0 bar, which is read by a pressure gauge indicating the internal pressure of the gas storage cylinder as shown in Figure 1.
b) If the compressor is equipped with an Anshekuo certified by TUV, the air storage cylinder can be released by tightening the screws on the bottom of the safety valve
c) Remove the check valve from the air storage cylinder
d) Disassemble the check valve and move it away from the O-ring.
e) Clean up and stop.
f) Install a new one. O-ring and reassemble

14. JUN-AIR air compressor pressure not increasing a) Check running time
b) 0-8bar shutdown time
c) Check for clogged filters
d) One way valve blockage issue.
e) Motor issues.

15. After starting the maintenance of the JUN-AIR 2000 series air compressor in the United States, release the pressure once, reach 7 bar, and then release the pressure again until the machine is stopped and the pressure is completely released.
