Basic knowledge of refrigeration compressor (technology sharing)

Compressor, a driven fluid machine that promotes low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks in 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 the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Compression → condensation (heat release) → expansion → evaporation (heat absorption) refrigeration cycle.

The status quo and development trend of China's gate valve market

Gate valves have the longest history of use, and are still used in various countries around the world, especially below DN300mm, which still dominate in various types of valves. The characteristic is that the pressure difference between the front and rear of the valve plate forces the valve plate to press on the valve seat on the right side of the outlet, with good sealing performance, and when the valve plate is fully opened, the pressure loss is small because the valve plate does not remain in the flow path. Used to cut off the medium in the pipeline.

Hitachi water source heat pump compressor

How does the air conditioning compressor work? The air-conditioning compressor is also called a rotary (rotor) compressor, and its working principle is to rely on an eccentric rotor under the action of spring force, the compressor, and the eccentric rotor are always in contact with the container separated by the sliding container Changes to achieve a process of compression. When the eccentric rotor rotates, the volume of the container changes and the gas is compressed.

Ways to reduce bearing noise

Ways to reduce bearing noise (1) Method of using chemical additives Adding certain chemical additives to the bearing lubricant can reduce bearing noise. For example, a low-noise grease containing noise-reducing additives produced by a factory in Tianjin can reduce bearing noise by 3.9-9.2dB from the original basis. , Suitable for use in miniature or small bearings.
