The invention relates to the technical field of hydraulic coupling control, and discloses a safety interlock protection device for a hydraulic coupling, which acquires the vibration and displacement of a component through a vibration and displacement detector; and acquires the temperature value of a component through a temperature detector Obtain the pressure value of the component through the pressure detector; perform logic calculation on the obtained vibration and displacement, temperature value and pressure value, and output the logic control signal; perform parking interlock protection and fault interlock alarm according to the logic control signal. The present invention uses the technological parameters of the hydraulic coupling itself and supporting equipment as interlocking protection conditions and starting conditions to protect the hydraulic coupling device and realize the interlocking protection of the centrifugal compressor unit.
Description
technical field [0001] The invention relates to the technical field of hydraulic coupling control, in particular to a safety interlock protection device for a hydraulic coupling. Background technique [0002] The hydraulic coupling is a hydraulic transmission device that uses the kinetic energy of the liquid to transmit energy. It uses liquid oil as the working medium, and converts the mechanical energy and the kinetic energy of the liquid through the pump wheel and the turbine, thereby connecting the prime mover and the working machine. Realize power transmission. As a flexible transmission device, hydraulic coupling is widely used in petrochemical equipment. In the prior art, the hydraulic coupling lacks an interlocking protection mechanism, and the working state of the hydraulic coupling is difficult to control, especially when an abnormal situation occurs, it cannot realize automatic safe parking or stop due to malfunction. Contents of the invention [0003] The inve...
