Product Description

                     Reciprotating Oil-Free Diaphragm/Piston Compressor
                                     ( Blue Font To View Hyperlink)

Our company specialize in making various kinds of compressors, such as:,, Air compressors,,,,etc. All products can be customized according to your parameters and other requirements.
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 type
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 Simple Description
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
No leakage: the compressor membrane head is sealed by static "O" ring. The O "ring is made of elastic material, with long service life and no dynamic seal to ensure no leakage during gas compression.
Corrosion resistance: the compressor membrane head can be made of 316L stainless steel, the diaphragm is made of 301 stainless steel.
Small tightening torque: "O" ring seal, can reduce flange bolt tightening torque, reduce shutdown maintenance time.
