Four control modes of servo drive

1.Feedback compensation open loop control. The accuracy of open-loop system is low, because the step error , start stop error and mechanical system error of servo driver will directly affect the positioning accuracy. This system has the advantages of both open-loop and closed-loop, that is, it has the stability of open-loop and the accuracy of closed-loop.

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
