Abstract

The invention provides a reversing valve unit action characteristic detection method and device. The reversing valve unit action characteristic detection method includes the following steps: (1) a driving signal for driving a driving coil of a reversing valve to act is emitted to the driving coil of the reversing valve, the time of emitting the driving signal is recorded, and data of changing of the current of the coil along with the time are measured; (2) the displacement and load of a valve element are measured to obtain data of change of the displacement and load of the valve element relative to the time; and (3) according to the measured data, the action characteristic of the reversing valve is analyzed. The motion characteristic of the valve element is obtained by detecting the displacement of the valve element, the current change of the coil and the load of the valve element, the measured motion characteristic is analyzed to obtain the fault situations of all components of the reversing valve, the reversing valve is maintained in a targeted mode, and the problem of low maintenance efficiency of a reversing valve in the prior art is solved.

Description

technical field [0001] The invention relates to a method and a device for detecting the action characteristics of a reversing valve unit. Background technique [0002] The hydraulic operating mechanism is a type of operating mechanism commonly used by GCB, which has the advantages of compact shape, stable energy storage, and high operating reliability, such as figure 2 As shown, the hydraulic mechanism can be divided into four parts as a reversing valve 16, an oil pump unit 18, an operating cylinder unit 19, and an accumulator unit 23. Through the reversing control of the reversing valve 16, the control oil circuit 21 and the high-pressure oil circuit are respectively connected 22. The low-pressure oil circuit 20 is connected to achieve the function of controlling the main piston 17 of the hydraulic mechanism to perform opening and closing operations. [0003] Such as figure 2 As shown, the reversing valve unit is composed of a valve body, a spool 1 and opening and closing...
