Mitsubishi Heavy Industries imported compressors for you

Anyone who knows a little about air conditioners knows that whether the air conditioner is a good compressor is the key. The role of the compressor is to convert the gas from a low-pressure low-temperature state to a high-temperature high-pressure gas, an器2䀀

Compressor operation in the heart of the refrigeration system in 2020

Compressor operation in the heart of the refrigeration system in 2020 A compressor is a fluid machine that raises low-pressure gas to high-pressure gas. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation (heat release) )-Expansion-evaporation (heat absorption) refrigeration cycle.

These several compressor failures need our attention

These several compressor failures need our attention In the refrigeration industry, everyone knows that the compressor is the core of the entire ice-making equipment. The quality of a compressor often determines the life of the refrigeration equipment, but no one can guarantee that the entire equipment will not have any problems during use, so It is very helpful for you to know some common faults that occur during the use of the compressor.

The formation and harm of carbon deposit in air compressor

How does air compressor coke formation form? The reasons for the formation of carbon deposits in air compressors are more complicated. In terms of air compressor oil lubrication, the main reason is that the oil used in the internal lubrication system of the air compressor is often in the form of mist and high temperature, high pressure, high oxygen partial pressure air and metal The contact of the catalyst causes the air compressor oil to rapidly oxidize and deteriorate.
