Application of SF6 Gas Compressor (Sulfur Hexafluoride Compressor):
This series compressor is suitable for recovering sulfur hexafluoride gas.
Suction pressure: can be minus pressure from -0.05Mpag to -.6Mpa(G)  (-0.05) ~ 0.6Mpa (G), Discharge pressure: can reach to 5.0Mpa (G)
SF6 gas can be highly efficient recycling by Keepwin SF6 recycling booster compressor.
And it also mainly used in the repair and maintenance of SF4 circuit breakers, recycling SR Gas in the circuit breaker.

The advantages  & usages of sulfur hexafluoride gas 

1. As a refrigerant in the refrigeration industry, the refrigeration range can be between -45°C and 0°C.

2.  The electrical industry uses its high dielectric strength and good arc extinguishing performance as an insulating material for high-voltage switches, large-capacity transformers, high-voltage cables and gases. Sulfur hexafluoride is widely used in the electrical industry for its good insulating properties and arc extinguishing properties, such as circuit breakers, high-voltage switches, high-voltage transformers, gas-enclosed combined capacitors, high-voltage transmission lines, transformers, etc. Gas insulators for electronic equipment, radar waveguides, particle accelerators, transformers, arresters, etc.

3. It is used as a desorbent in the mining industry to replace oxygen in coal dust in mines.

4. Play role as a tracer. Because sulfur hexafluoride is highly sensitive, non-toxic, stable in performance, reliable in inspection methods, and has very little content in nature, it is often used as a tracer in the environmental protection industry. For air pollution monitoring and hydrogeological research. As a widely used tracer for the determination of air pollution, sulfur hexafluoride has a tracer distance of up to 100 kilometers.

5. Electronic grade sulfur hexafluoride (SF6) is suitable for cleaning and etching processes in TFT-LCD panel factories and semiconductor factories and can be used as a single-film fiber isolation layer dopant in the manufacturing process of optical fibers. Electronic grade high-purity sulfur hexafluoride is an ideal electronic etchant and is widely used in the field of microelectronics technology.

6. SF6 is also widely used in metal smelting (such as magnesium alloy melting furnace protective gas), aerospace, medical (X-ray machine, laser machine), meteorology ( Tracer analysis), chemical industry (advanced car tires, new fire extinguishers), etc. In the smelting and casting process of non-ferrous metals, sulfur hexafluoride can prevent the oxidation of magnesium and its alloy melts, and can also be used for degassing and purification of aluminum and its alloy melts.

7. In the pharmaceutical industry, the most advanced contrast agent ultrasound method CnTI currently uses sulfur hexafluoride as the contrast agent. The other name called SonoVue (SonoVue), can diagnose, and is said to increase the screw pressure, so as to provide full power independent of diving depth.

8. Inflate pure gaseous sulfur hexafluoride into the finished sports ball inner tube to reach a usable air pressure. The inner tube pressure of the sports ball will remain stable for a long time. The sports ball can be used for a long time without the need for a second inflation to supplement the air pressure.

9.  Standard gas, leak detection gas, carrier gas of chromatograph.


The Oil free Oxygen piston booster compressor is widely used in oxygen industry such as air separation oxygen plant and medical industry.

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.
