Product Description

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 resulting 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 the diaphragm compressor, in order to compensate for 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.
