{"id":167,"count":1,"description":"Diaphragm Compressors\r\nCompressor units are designed for pumping and compressing liquids and gases. A membrane compressor belongs to the group of positive displacement units. The pressure of the gas medium passing through it increases due to volume changes caused by the bending of a flexible plate, rather than piston movement as in piston variants.\r\nOperating Principle\r\n\r\nmembrane deflection by the rod when the device is activated to increase the working chamber volume and create vacuum;\r\nair intake through the inlet port;\r\nreverse stroke of the crank-connecting rod mechanism to reduce volume;\r\nexpulsion of working medium through the outlet port.\r\n\r\nThe diaphragm type is selected depending on the composition of compressed substances.\r\n\r\nAdvantages\r\n\r\nabsence of lubrication in the working space, which requires no additional costs and does not contaminate pumped compositions;\r\npossibility of pressure increase through installation of two chambers;\r\nselection of diaphragm, housing, and valve types depending on the degree of medium aggressiveness;\r\nhigh reliability and durability due to absence of friction elements in the design;\r\nsimple design requiring minimal maintenance;\r\nlow noise and vibration levels;\r\ncapability for dry operation;\r\nhigh compression ratio with fewer stages compared to piston variants;\r\nsealed working space preventing gas leakage;\r\nsafety for the environment and nearby personnel.\r\n\r\nThere are also disadvantages: the diaphragm and valves deteriorate quickly with improper operation. Additionally, the pump provides relatively low pressure with fairly uneven delivery.\r\nApplications\r\nDiaphragm air and nitrogen compressors, due to their characteristics, find application in various industries:\r\n\r\nnuclear power;\r\nfood production;\r\nchemical and paint industries;\r\nagriculture;\r\nmedicine and pharmaceuticals;\r\nscientific research.\r\n\r\nThis type of compressor is suitable for compressing ultra-pure and toxic gases when leakage and oil contamination in the housing cavity are unacceptable. Membrane units are used for a wide range of gaseous and liquid substances without restrictions due to oil contact and at high operating pressure levels. Piston variants have lower compression, and there is also a possibility of oil contamination entering the chamber even in oil-free designs if separation rings wear out.\r\nOur Offers\r\nRusGazCryo LLC, the official representative of Hangzhou Oxygen Plant Group, offers a wide selection of diaphragm compressor models.
