The diaphragm compressor is a volume compressor of a special structure. It is the highest -level compression method in the field of gas compression. This compression method does not have secondary pollution. It has very good protection for the compressed gas. Good sealing, compressed gas is not polluted by lubricating oil and other solid impurities. Therefore, it is suitable for compressing high purity, rare precious, flammable and explosive, toxic and harmful, corrosive, and high pressure gas.
diaphragm compressor is a variant of the classic reciprocating compressor with backup and piston rings and rod seal. The compression of gas occurs by means of a flexible membrane, instead of an intake element. The back and forth moving membrane is driven by a rod and a crankshaft mechanism. Only the membrane and the compressor box come in touch with pumped gas. For this reason this construction is the best suited for pumping toxic and explosive gases. The membrane has to be reliable enough to take the strain of pumped gas. It must also have adequate chemical properties and sufficient temperature resistance.
The diaphragm compressor is mainly composed of motors, bases, crankshaft boxes, crankshaft connecting rods, cylinder components, oil and gas pipelines, electrical control systems, and some accessories.
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)
GD Model Instruction
GD diaphragm compressor is a special structure of the volumetric compressor, is the highest level of compression in the field of gas compression, this compression method Without secondary pollution, it can ensure the purity of gas is more than 5, and it has very good protection against compressed gas. It has the characteristics of large compression ratio, good sealing performance, and the compressed gas is not polluted by lubricating oil and other solid impurities. Therefore, it is suitable for compressing high-purity, rare and precious, flammable, explosive, toxic, harmful, corrosive and high-pressure gases. The compression method is generally specified in the world for compressing high-purity gas, flammable and explosive gas, toxic gas and oxygen. Etc. (such as nitrogen diaphragm compressor, oxygen diaphragm compressor, hydrogen sulfide diaphragm compressor, argon diaphragm compressor, etc.).
GD diaphragm compressor for my company independent research and development of large diaphragm compressor, its advantages are: high compression ratio, large displacement, large piston force, stable running, high exhaust pressure, etc, has been widely used and petroleum chemical industry and nuclear power plant, and so on,.Two GD type diaphragm compressor cylinder arrangement for symmetrically arranged in parallel, more suitable for the petrochemical and nuclear power plant such as uninterrupted operation for a long time, because of the cylinder body symmetry, run up against other arrangement of diaphragm compressor is the most stable operation, running, small vibration from the ground clearance is more convenient in maintenance.
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.

The natural gas compressor is consists of a three pieces of diaphragms. The diaphragm is clamped along the surrounding area by the hydraulic oil side and the process gas side of the process. The diaphragm is driven by the hydraulic driver in the film head to achieve the compression and transportation of the gas. The main body of the diaphragm compressor consists of two systems: the hydraulic oil system and the gas compression system, and the metal membrane separates these two systems.
Basically, the structure of the diaphragm compressor is divided into two parts: the hydraulic framework and the pneumatic force framework. During the compression process, there are two steps: the suction stroke and the delivery stroke.
