Piston Compressor Repair Instructions for Electric Vehicle Motor Testing

Specifications

the overhaul cycle of piston compressors in electric vehicle motor testing is recommended to be overhauled every 8,000 hours of operation. the main part of the piston compressor overhaul in electric vehicle motor testing is to inspect and clean the parts and measure the wear of the parts: cylinders, pistons, piston rings, crankshafts, bearings, connecting rods, suction and exhaust valves, oil pumps, etc. It can be trimmed with slight wear and should be replaced if it is worn hard. Check safety valves and various instruments (shall be performed by a qualified department). Clean the refrigeration oil system, the refrigerant system, the filter of the water system, and so on.

in the electric vehicle motor test, the cycle of the piston compressor in the repair is about 3,000 to 4,000 hours per operation for a medium repair. the content of the repair is to check and correct the cylinder and piston clearance, the piston ring lock clearance, the connecting rod size head and crank pin clearance, the main bearing and the main shaft diameter clearance, and the clearance between the air valve and the piston. Wait. Check the wear level of piston pin, cylinder, crankshaft and other components. Check the lubrication system. Check if the coupling and anchor bolts are loose.

in the electric vehicle motor test, the cycle of minor repair of the piston compressor is carried out after a medium repair, and a minor repair is performed every 1000 to 1200 hours. the minor repair is to clean the cooling water pump; check the piston, gas ring, oil ring and suction and exhaust valve, replace the damaged valve plate and valve spring; check the connecting rod size head bush, clean the crankcase, oil filter and suction filter Replace the refrigerating machine oil; check the coaxiality of the motor and the crankshaft.

in the electric motor test, the piston compressor is one of the most important accessories for its operation. Its performance problem is very important. Therefore, we try our best to ensure the efficient operation of the electric motor motor test compressor.
