Background
The diaphragm compressor is a driven fluid machine for lifting low-pressure gas into high-pressure gas, and is particularly suitable for pressurizing high-purity gas, extremely toxic gas and other gases. The membrane press mainly comprises a crankcase, a crankshaft, a connecting rod, a crosshead, a piston, a cylinder and the like, wherein the cylinder comprises a cylinder cover, an oil distribution disc, a cylinder body, an air valve and other parts. The cylinder cover and the oil distribution disc are respectively provided with a curved surface with the same coordinate, the diaphragm is clamped between the curved surfaces, the cylinder cover is provided with an air suction valve and an air exhaust valve, and the oil distribution disc is drilled with small holes so that a cavity below the diaphragm is communicated with the oil cylinder. The piston of the cylinder is connected with a main connecting rod, the crosshead is connected with the connecting rod, the crank pin is connected with the big end of the connecting rod, and the crankshaft is supported on a crankcase through two bearings. Because the diaphragm separates the cylinder and the oil cylinder completely, the compressed medium is not contacted with the oil, thereby avoiding the pollution of the oil and ensuring the purity of the compressed medium. The cylinder is composed of a curved surface of the cylinder cover and a diaphragm, and is a closed cavity, so that the cylinder has excellent sealing performance. The basic part composed of a crank case, a crank shaft, a connecting rod, a crosshead and the like is similar to a conventional reciprocating piston compressor, but the special structure of the diaphragm compressor ensures that compressed process gas cannot be polluted by lubricating oil in the crank case and can also ensure that gas cannot enter the crank case, the crank case or a middle body of the conventional diaphragm compressor can exchange air with the outside only through a respirator, the humidity in the air in different areas is different, when the humidity is high, the lubricating oil in the crank case is easy to deteriorate, the service life of the lubricating oil is shortened, when the humidity is serious, a crank shaft friction part cannot effectively form an oil film layer, and if the friction part is in dry friction, mechanical accidents are easy to cause.
To solve the above problems, the inventor developed a drying apparatus.
