모터 테스트 냉각기 오일 품질은 크랭크샤프트 마모에 영향을 미치는 주요 원인 중 하나 일 수 있습니다. 냉각기 냉동 시스템에 엔진 오일을 사용하는 경우, 요구 사항을 충족하지 못하고 품질이 좋지 않은 엔진 오일은 크랭크샤프트 마모를 유발할 수 있습니다. 고속 멀티 실린더 컴프레서는 고속, 고부하 및 높은 배기가스 온도로 인해 모터 테스트 칠러 오일의 품질 및 윤활 성능에 대한 요구 사항이 높습니다. 모터 테스트 칠러 냉동 컴프레서 ...

Motor test chiller refrigeration compressor oil selection in addition to the choice of compressor type, but also according to the type of refrigerant used in the refrigeration system, commonly used ammonia, R23 and R22 and R404a, etc., taking into account the motor Test the chiller operating conditions (such as exhaust temperature, pressure, etc.) of the refrigeration system when different refrigerants are used, all of which will affect the lubrication conditions of the refrigeration oil, so the choice of motor to test the chiller oil must consider the refrigerant used, This is related to the mutual solubility of the refrigerant, high and low temperature performance, no water content, and high chemical inertness with the refrigerant.

If the viscosity of the oil is too low and the lubricating oil is not clean, the motor will test the chiller crankshaft for abnormal wear and damage. Therefore, the refrigerating machine oil of suitable quality and suitable viscosity grade must be selected in strict accordance with the technical specifications of the motor test chiller compressor. In addition, in the process of using the motor to test the chiller, it is necessary to strengthen the cleaning of the lubrication system, clean the compressor regularly, and replace the new oil to ensure that the crankshaft of the compressor is always in a good lubrication state.

Motor test chiller operation often occurs in the wet stroke, the compressor wet stroke is the liquid into the crankcase, mixed with the frozen oil and foam. The lubrication effect of the friction parts of the motor test chiller is reduced to increase the wear. The use of high-efficiency oil separators and adjustment of refrigeration conditions can effectively prevent the wet stroke phenomenon of the refrigeration system.

The motor test chiller crankshaft upper axle and connecting rod bushings are mostly made of babbitt. Motor testing of impurities or wear metal particles in the chiller alloy can cause increased crankshaft wear if embedded in the metal layer. Therefore, the motor test chiller should use high quality bearing pads or periodically replace the bearing pads to prevent or slow the crankshaft wear.

The motor test chiller runs more in the new energy vehicle motor test, so it needs specific attention to its operating state to ensure efficient operation.
