What should I do if my semi-hermetic piston compressor does not start properly?

New compressor can not start normally, these five aspects of the inspection must be meticulous.

1. First of all, detect whether it is caused by low voltage or bad connection of motor line: if it is indeed low voltage of grid, start again after the grid voltage is restored to normal; if it is bad contact of line, test the connection of line and motor and repair it.

2. Check whether the exhaust valve piece is leaking: If the exhaust valve piece is broken or not sealed tightly, it will cause high pressure in the crankcase, resulting in failure to start normally. Need to replace the exhaust valve and sealing line can be.

3. Check whether the energy regulator is out of order: mainly check whether the oil supply line is clogged, low pressure, oil piston stuck and other conditions and repair according to the cause of the failure.

4. Check whether the temperature controller is damaged or out of tune: if it is out of tune, the temperature controller should be adjusted; if it is damaged, it should be repaired or replaced.

5. Check whether the pressure relay is out of order: repair the pressure relay and reset the pressure parameters can be.
