Process Principle
Diaphragm compressor according to the needs of the user, choose the right type of compressor to meet the needs of the user. The diaphragm of the metal diaphragm compressor completely separates the gas from the hydraulic oil system to ensure the purity of the gas and no pollution to the gas. At the same time, advanced manufacturing technology and accurate membrane cavity design technology are adopted to ensure the service life of the diaphragm compressor diaphragm. No pollution: the metal diaphragm group completely separates the process gas from the hydraulic oil and lubricating oil parts to ensure the gas purity.

Main Structure
Diaphragm compressor structure is mainly composed of motor, base, crankcase, crankshaft linkage mechanism, cylinder components, crankshaft connecting rod, piston, oil and gas pipeline, electric control system and some accessories.
Gas Media
Our compressors can compress ammonia, propylene, nitrogen, oxygen, helium, hydrogen, hydrogen chloride, argon, hydrogen chloride, hydrogen sulfide, hydrogen bromide, ethylene, acetylene, etc.(Nitrogen diaphragm compressor,bottle filling compressor,oxygen diaphragm compressor)
GL Model Instruction
The GL series diaphragm compressor is mainly composed of vertical and horizontal cylinders arranged in L-shape, crankcase, crankshaft connecting rod mechanism, base and cooler.The cooling method is water-cooled. Many small and medium-sized process compressors also use L-type compressors. The development prospects of L-type compressors in the petrochemical industry are becoming brighter.

Advantages
1.Good sealing performance
Diaphragm compressor is a kind of special structure displacement compressor.The gas does not need lubrication,the sealing performance is good,the compression medium does not contact with any lubricant,and there will be no pollution in the compression process.It is especially suitable for high purity(99.9999%),rate,extremely corrosive,toxic and harmful,inflammable and explosive.Compression,transportation and bottle filling of radioactive gases.Membrane head is sealed with inlaid double O-ring,and its sealing effect is far better than that of open type.
2.Cylinder has good heat dissipation performance
The working cylinder of diaphragm compressor has good heat dissipation performance and is close to isothermal compression.It can adopt higher compression ratio and is suitable for compressing high-pressure gas.
3.Compressor speed is low and service life of vulnerable parts is prolonged.The new type of diaphragm cavity curve improve the volume efficiency of the compressor,optimize the value type,and adopt special heat treatment method for diaphragm,which greatly improves the service life of the compressor.
4.The high efficiency cooler is adopted,which makes the whole machine low in temperature and high in efficiency.The service life of lubricating oil,O-ring and value spring can be prolonged appropriately .Under the condition of meeting the buyer's technological parameters,the structure is more advanced,reasonable and energy-saving.
5.The diaphragm rupture alarm structure is advanced,reasonable and reliable.The diaphragm installation has no directionality and is easy to replace.
6.The parts and components of the whole equipment are concentrated on a skid-mounted chassis,which is convenient for transportation,installation and management.
