Shallow oil return method of parallel refrigeration compressors

Compressor oil return is one of the key problems in piping design, and it is also a troublesome problem that must be solved; the solubility of refrigerant and lubricating oil should be miscible, slightly soluble, and miscible at high pressure and separate at low pressure. ; The problem of oil return often occurs in the exhaust pipe and return pipe. Today, the analysis is the oil return problem of parallel compressors

Compressed air filter classification and applicable occasions

Compressed air filter is a device for filtering and purifying compressed air. Generally, the compressed air filter element is composed of fiber media, filter mesh, sponge and other materials. The solid and liquid particles (drops) in the compressed air are intercepted by the filter material and condensed on the surface (inside and outside) of the filter element.
