Detailed explanation of the compressor in the high and low temperature impact test machine

Many customersTension tester, I know a lot about universal testing machines and are familiar with the operation, but I know very little about impact testing machines. For customers to learn more about the devices of high and low temperature impact testing machines, Jinan Hengsi Shanda Instrument Co., Ltd. has made the following detailed understanding of its compressor components:

High and low temperaturesImpact testing machineOne of the four major components of refrigeration: a compressor, a driven fluid machine that promotes low-pressure gas to high-pressure. It is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, and then drives the piston to compress it through the motor operation, and discharges high-temperature and high-pressure refrigerant liquid to the exhaust pipe, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression-condensation-expansion-evaporation (heat absorption).

The specifications of the compressor are divided by input power. Generally, the difference between each specification is about 50W. In addition, it can also be divided according to the cylinder volume. The main performance indicators of compressors include input and output power, performance coefficient, cooling capacity, starting current, operating current, rated voltage, frequency, cylinder volume, noise, etc. To measure the performance of a compressor, it mainly compares three aspects: weight, efficiency and noise.

In addition, according to Chinese standards, its safety performance inspection is carried out in accordance with the items stipulated in GB4706.17-2004. The main items are electrical strength, leakage current, blockage, and overload operation tests. The compressor used for the high and low temperature impact test machine is located at the bottom of the equipment and is an indispensable member of the equipment when performing refrigeration tests.
