Compressor noise requires compressor noise according to the conditions specified in the table

Test pressure project test pressure pressure test airtight test, the compressor should be well sealed, there must be no refrigerant leakage. The lubrication method of the compressor is pressure lubrication or splash lubrication. When using pressure lubrication, the oil pressure of the lubrication system and the pressure difference in the crankcase of the compressor. When the ambient temperature is 43, the temperature of the lubricating oil in the crankcase of the compressor should not be higher than that of the compressor with the safety valve. The safety valve is sensitive and airtight and safe and reliable. The compressor should be able to withstand the shock and vibration generated during normal operation. The average time between failures of the compressor should be no less than the requirements of the electromagnetic clutch of the compressor. There should be no breakdown between the electromagnetic clutch wire of the compressor and the coil housing.

The insulation resistance between the electromagnetic clutch wire of the compressor and the coil housing should be greater than or equal to the condition. The static clutch torque of the electromagnetic clutch of the compressor should meet the design requirements. Compressor noise requirements Compressor noise according to the conditions specified in the table, the noise level should meet the design requirements. Compressor Corrosion Resistant Requirements The compressor is tested according to the salt spray test method, and the test results should meet the design requirements. The compressor drive requires the compressor to be either direct or belt driven. When direct drive is used, the compressor should be equipped with an unloading starter. This paper introduces the characteristics of the compressor for air-conditioner of passenger car to meet the requirements of wide-speed refrigeration conditions when the passenger car is driving. At the same time, it analyzes the differences and similarities of the existing test standards of the compressor, and proposes the air-conditioning of urban public transport and long-distance transport passenger cars. The compressor should be designed with two speed conditions. And put forward a reference for the development of passenger car air conditioning compressor standards in the case of refrigeration performance, airtightness, reliability, noise and corrosion prevention.
