Diaphragm Compressor 100% purity no leakage Oil-free Oxygen Booster Compressor The diaphragm compressor booster is a special structure of the volume-type compressor with high compression ratio, good leak tightness, compressed gas without lubricating oil and other solid impurities contaminated features, So it's suitable for high purity compression, rare, valuable, inflammable, explosive, toxic, harmful, corrosive, and high pressure gas
Advantages of Diaphragm compressor:
1. Oil-free compression due to the hermetic separation between gas and oil chamber.
2. Abrasion-free compression due to static seals in the gas stream
3. Automatic shutdown in case of a diaphragm failure prevents damage
4. High Compression Ratios-Discharge pressure up to 1000bar.
5. Contamination Free Compression
6. Corrosion Resistance
7. High Reliability
As a displacement compressor with special, diaphragm compressor is characterized by large compression ratio, good sealing performance, and that the compress air will not be polluted by lubricant or other solid impurities.Therefore diaphragm compressor is applicable to compress high-purity, rare and precious, flammable and explosive, toxic and hazardous,corrosive and high pressure gases.
Keepwin diaphragm compressors consist of four types that are Z, V, L and D type.The exhaust pressure ranges from 1.3 to 100 Mpa. The products are widely used in the industries of national defense, scientific research, petrochemical, nuclear power, parmaceutical, food-stuff and gas separation.

Main technical data
Cylinder
All the cylinders comprise upper plate, diaphragms, and cylinder body etc. The diaphragms are clamped between the cylinder cover and cylinder body. The cylinder cover and cylinder body each has a concave recess hollowed out in their contacting faces. The gas cylinder is formed between cylinder cover concave recess and diaphragms. Both suction valve and discharge valve are fitted on the upper plate. Among of them, the discharge valve is located on the center of the upper plate. The evenly located small oil holes are on the cylinder body to deliver the oil pressure inside the oil cylinder to the bottom of diaphragms (each diaphragm compressor's cylinder has three piece diaphragm.)
Pressure Regulating Valve
The oil pressure of oil cylinder is regulated by the tension of the valve spring.In case the oil pressure is higher than the regulated value, turn the regulating bolt counter-clockwise to loosen the spring tension, but turn the regulating bolt clockwise to tighten the spring, when the oil pressure is lower than the regulated value. When the oil pressure meets the required value, the regulating bolt must be locked with a lock-nut. The oil pressure of the oil cylinder shall always be higher than the discharge pressure by 15~20%. But the oil and gas differential pressure shall not be lower than 0.3MPa or higher than 1.5MPa.
Cooler
The cooler structure is the double-wall pipe type. The circular space between the outer and inner pipe is the cooling water passage and the inner pipe is the gas passage. Normally the water inlet port is at the lower side and the water outlet port is at the upper side. The flow direction of cooling water and gas is on the contrary.
Oil Pressure Measuring Device
The measuring device of oil cylinder discharge pressure consists of shock-proof pressure gauge, check valve and unloading valve. The case of the pressure gauge is totally airproof and filled with damping liquid. The inner devices of gauge is immersed in the liquid, which makes the pressure gauge hands stable through the function of the viscosity of damping liquid. The unloading valve is fitted under the gauge to discharge the remained air in the oil pipeline and to unload the oil pressure gauge. Also the check valve connecting with oil cylinder through pipeline is fitted under the unloading valve.
Oil pipes
Oil pipes consist of lube oil pipe and oil pressure secure system.
The lubrication for the driving device adopts gear oil pump circulation pressure lubricating. The lube oil stored in the frame oil tank enters into the gear oil pump after being filtered and is pressed into the oil holes in the crankshaft through the gear oil pump to lubricate the crankshaft friction surface. At the same time, part of the lube oil reaches the crosshead pin and crosshead along the oil holes in the connecting rod to lubricate the friction surface. The oil pressure of gear oil pump shall be kept between 0.3~0.5Mpa, and the bearings at the two ends of crankshaft is splash lubricated.
Oil pressure secure system consists of oil compensating pipe, pressure-measuring pipe and oil return pipe. The oil output from the oil compensating pump will supplement oil for compressor cylinders through the oil compensating pipe and the excess oil returns to the crankcase through the pressure-regulating valve.
