Method for determining locking temperature of pump elevated temperature test

Abstract

Method for confirming the lock-up temperature of the pump warm-up test. The pump temperature rise test is a basic verification test for the design of the pump body. By confirming the locking temperature and unlocking temperature of the pump body, it is confirmed whether the gaps in the working state of the pump body are the optimal gaps. The method of confirming the locking temperature of the pump heating test, the first step: assemble the rotary compressor pump body, and adjust all the assembly clearances to the minimum clearance specified on the drawing; the second step: rotate the assembled pump body , to confirm whether the pump body can operate normally; the third step is to put the pump body into the incubator, and confirm the locking temperature of the pump body; the fourth step: confirm the unlocking temperature of the pump body; the fifth step: wait as described After the pump body returns to normal temperature, disassemble and confirm the pump body parameters. This product is used to confirm the pump temperature rise test for the clearance of the compressor pump body, and the method for confirming the locking temperature of the pump temperature rise test.

Description

[0001] Technical field: The present invention relates to a basic test method for rotary compressors Background technique: [0002] The production technology of the rotary compressor originated from Japan. The pump body includes rolling rotors, cylinders, crankshafts, upper and lower bearings, blades, and springs. The working process is that the motor is powered by the crankshaft, and the eccentric circle of the driven eccentric crankshaft drives the cylindrical rolling rotor to rotate in the cylinder. It is an air suction chamber and an exhaust chamber. There is an air suction port on the cylinder corresponding to the position of the right air suction chamber, an exhaust port on the bearing corresponding to the position of the left exhaust chamber, and an exhaust cutout on the cylinder. The front and rear of the cylinder are sealed by bearings, the long axis and short axis of the crankshaft are respectively supported by the upper and lower bearings, the long axis of the cranks...

AI Technical Summary

Problems solved by technology

The traditional pump temperature rise test has disadvantages such as long test time and inaccurate temperature confirmation. Since there are radiation tubes inside the thermostat, the pump body near the inside is generally easy to lock, while the pump body near the door is extremely difficult to lock. Take it out of the incubator, turn it by hand to confirm whether it is locked, and you will also get cold. If you put it in the incubator again and unlock it, sometimes it is difficult to confirm whether it is cold outside, and the temperature is uneven when you return to the incubator. Unlocked or at the same temperature It is unlocked after the download is stable, that is, the confirmation result will be affected by the ambient temperature and the operator's level, and there is considerable inaccuracy
