Open compressors
Pumps with external disk requires gland, or of the press, where the shaft passes out of the crankcase, known as open compressors. The drive comes with an external air-cooled engine or other tractor. Open-compressors required when using refrigerants such as ammonia, which is not compatible with the copper used in electric motors. Open compressors can be belt-driven or directly connected to the motor shaft. Belt drives give the opportunity to match the speed of the power requirements, but they must be adequately protected, and, as a side bearing load compressor, not all compressors are suitable. This type of drive is widely used in transport applications, where compressors with a motor-driven vehicle or in a separate diesel engine.
Shaft seal open for compressors, as a rule, consists of carbon ring rotating in contact with the polished metal lining rings, Assembly, well lubricated. To communicate on all operating pressure in the crankcase, carbon ring spring and allows easy movement of the shaft.....
