（1） Introduction to diaphragm compressor

Diaphragm compressor is named because it has a special diaphragm to separate the compressed gas from the outside world. Diaphragm compressor is also called "membrane compressor".

In diaphragm compressor, the function of cylinder is completed by a membrane cavity. The so-called membrane cavity is a cavity composed of a cylinder head with a dome shaped surface and an oil distribution plate (or cylinder block). The periphery of the membrane is fastened between the cylinder head and the oil distribution plate (or cylinder block). When the diaphragm flexes and deforms up and down, the volume in the membrane cavity changes accordingly, which plays the role of suction and compression. Therefore, in the diaphragm compressor, the diaphragm plays the role of piston in the general compressor. The closed cavity between the cylinder head and the diaphragm is the air cavity, and the cavity between the oil distribution plate (or cylinder block) and the diaphragm is the oil cavity.

Because the diaphragm of the diaphragm compressor completely separates the cylinder from the oil cylinder, the compressed medium does not contact with the oil, so as to avoid oil pollution and ensure the purity of the compressed medium. The cylinder is composed of cylinder head surface and diaphragm. It is a closed cavity, so it has good sealing. Because the membrane cavity does not need lubrication, has good sealing, and the gas does not contact with any lubricant, the purity of compressed gas is very high, especially suitable for the compression, transportation or bottling of some precious rare gases.

（2） Characteristics of diaphragm compressor

Diaphragm compressor is a reciprocating compressor with special structure. It has large compression ratio and good sealing. The compressed gas is not polluted by lubricating oil and other solid impurities. It is suitable for compressing gases with high purity, rare and precious, flammable and explosive, toxic and harmful, corrosive and high pressure.

The main features of the diaphragm compressor independently produced by our company are as follows:

The compressed gas is not polluted by lubricating oil and other solid impurities. It is suitable for compressing gases with high purity, rare and precious, flammable and explosive, toxic and harmful, corrosive and high pressure.  

The main features of the diaphragm compressor independently produced by our company are as follows:

1. The gas is not in contact with any medium and is suitable for compressing rare and high-purity gas.

2. The compressor has good sealing and no leakage, and compresses toxic, harmful, flammable and explosive gases and special gases.

3. The new membrane cavity curve improves the volumetric efficiency of the compressor and improves the service life of vulnerable parts, diaphragm and air valve.

4. The independent oil pump station with complete functions provides lubricating oil with stable pressure, clean quality and sufficient cooling for compressor lubrication and oil cylinder work.

5. The whole machine has compact and reasonable structure, which is convenient for equipment transportation, installation and maintenance; Stable and reliable operation, low vibration and low noise.
