The diaphragm compressor is driven by a motor, and rotates the crankshaft via a belt pulley, then makes the piston in the oil cylinder reciprocate through a connecting rod, thus result in the diaphragm vibrating to and fro through pushing the oil. The processes of suction and discharge are completed by each vibration of the diaphragm under the control of the suction valve and the discharge valve. A small amount of oil in the oil cylinder leaks into the oil case through the clearance between the oil cylinder and the ring groove during the operation of diaphragm compressor, in order to compensate the oil loss to make the diaphragm close to the curved surface of compression head cover after the end of compression stroke for completely discharging the compressed media. The oil amount is slightly more than the oil leakage amount when the oil is injected into the oil cylinder by the oil compensation pump during the suction process of the compressor, the excess oil flow back to the crankcase by the pressure regulation valve of oil pressure while the end of compressor stroke.
The compressed media doesn't contact with the oil due to the diaphragm completely separating the gas chamber from the oil chamber, therefore the purity of the compressed media can be guaranteed due to no oil contamination. The gas chamber is composed of the contoured cover and the diaphragm, which is a closed chamber resulting in a good sealing performance.
The diaphragm compressor is a kind of reciprocating compressor with a special structure, big compression ratio and good sealing performance, the compressed gas is not contaminated by the lube oil and the other solid impurities, which is suitable for compressing high purity gas, rare and precious gas, flammable and explosive gas, poisonous and harmful gas, corrosive gas and high pressure gas.
Product features:
1. Good sealing performance:
Diaphragm compressor is a kind of special structure positive displacement compressor, the gas does not need lubrication, good sealing performance, the compression medium does not contact with any lubricant, will not produce any contamination in the compression process, Especially suitable for high purity (99.9999% above), rare, highly corrosive, toxic ,harmful, flammable , explosive and radioactive gas compression, transportation and bottle filling.
2.Cylinder heat dissipation performance is good:
Compressor cylinder heat dissipation performance is good, close to isothermal compression, can use high compression ratio, suitable for compression of high pressure gas.
Technological advantage
1, Low of speed prolong the service life of wearing parts. The new membrane cavity curve improves the volume efficiency.optimizes the gas valve profile, and the diaphragm adopts a special heat treatment method, greatly prolongs the service life.
2, the use of high efficiency cooler, so that the temperature is low, high efficiency, can properly extend the life of lubricating oil, O-ring, valve spring. Under the condition of meeting the technological parameters, the structure is more advanced, reasonable and energy saving.
3, the cylinder head using Mosaic double O-ring seal, its sealing effect is far better than open head.
4, diaphragm rupture alarm structure advanced, reasonable, reliable, diaphragm installation is non-directional, easy to replace.
5. The parts of the whole equipment are concentrated on a common skid which is easy to transport, install and operation.
