Product Description
1. compressor product introduction
1. Strict quality control, superior performance
The compressor adopts advanced structural design, strict material screening, advanced machining, and precise instrument testing; the company has a scientific quality management system, and implements strict quality control from design, processing, equipment to management. The semi-hermetic compressor has superior product performance.
2, small body light
The semi-hermetic compressor is small in size, light in weight and relatively large in refrigerating capacity.
3. Wide range of use
The compressor uses R22 refrigerant, and also applies RI34A, R404A, R407A, R407B, R407C refrigerant. From low temperature to high temperature can be widely used. According to international environmental requirements, it is recommended not to use R12 and R502.
4. Generalization of parts
The valve plate assembly, piston, connecting rod and other parts of the same series of compressors can be used universally for easy maintenance.
5. Small operation noise
Due to the reasonable design and high machining accuracy, the machine has good dynamic balance, stable operation and low noise.
6 Good reliability.
The motor of the compressor is built-in and has no shaft seal device, which can realize reliable operation without refrigerant leakage and oil leakage. In addition, the compressor is attached with an oil separation mechanism, the amount of oil discharged during operation is very small, and it can work stably under low temperature conditions.
7. Reliable safety devices
In the compressor is equipped with thermal protection device, exhaust temperature protection device (optional) and safety valve (excluding small four-cylinder model), can prevent the motor, compressor overheating and compressor (excluding small four-cylinder model) overpressure operation.
Working principle of 2. compressor
The refrigeration compressor is one of the four basic devices in the compression refrigeration cycle system. The refrigeration compressor produced by our company is a piston type semi closed refrigeration compressor. The piston reciprocates in the cylinder through the crank connecting rod mechanism of the refrigeration compressor. The piston reciprocates once every time the crankshaft rotates, completing the working cycle composed of three (ideal) processes of suction, compression and exhaust of refrigerant gas, it realizes that the refrigerant of the refrigeration system evaporates and vaporizes to absorb the heat of the surrounding medium under the condition of low temperature and low pressure, and condenses and liquefies under the condition of normal temperature and high pressure to release the heat, which is taken away by the cooling water (or air), so as to achieve the purpose of refrigeration.
