What is the cause of diaphragm compressor diaphragm rupture?

What is the cause of diaphragm compressor diaphragm rupture?

Film rupture is not normal rupture, that is, the diaphragm compressor does not reach the limit of service life caused by rupture, or continuous rupture.

Root cause: the metal chips or sand particles brought by the diaphragm compressor is not cleaned up, so that it is cracked or penetrated under ultra-high pressure; the hydraulic cylinder sleeve is loose, which increases the total oil discharge area of the piston rod, which increases the working pressure of the oil discharge, exceeding the yield limit of the diaphragm compressor diaphragm. Such things are very few, but not easy to find out, and can not find out the cause.

Resolution method: the diaphragm compressor is equipped with diaphragm rupture detection system. If the steam body is released in the discharge valve, the gas end diaphragm is broken; if the oil is released, it indicates the oil end diaphragm rupture; if the release gas contains oil, it indicates that both diaphragm are cracked.

Treatment method: replace the diaphragm compressor in strict accordance with the requirements; if the cylinder sleeve is loose, repair and fix.

The cylinder head sounds too loud

The diaphragm compressor operates normally in a small sound, but sometimes (especially after maintenance) the cylinder hair gives a large sound of metal material percussion.

Root cause: the pressure limit valve is in the open position, or the torsion spring of the pressure limit valve is too loose, or the diaphragm compressor compensation pump is not working normally. Before the first conditions, the consumption of the pressure limit valve exceeds the compensation of the compensation pump, resulting in a large indoor space of the hydraulic cylinder. At the four stroke of the diaphragm compressor, the diaphragm immediately touches with the packing below. If the compensation pump work is not normal, the cylinder block can not fill the oil leakage, the problem will also occur.

Resolution method: directed at the cylinder head of the diaphragm compressor, listen to the clear sound of "when, when, when"; see if the pressure limit valve is in the normal position, the compensation pump plunger pump posture, and the oil pipe.

Treatment method: tap the pressure valve of the diaphragm compressor into the operating part; release the pressure valve nut, slowly tighten the torsion spring until the brittle sound of the cylinder head fades and the normal exhaust pressure goes, and finally tighten the anti-loosening nut; find the main reasons for the abnormal work of the compensation pump and handle it properly.
