Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in FIG. 1, the embodiment of the present invention adopts a plunger pump 19 as the power source of the hydraulic system when the hydraulic system works, and the plunger pump 19 is connected with an overflow valve 21, an electromagnetic directional valve 1, a hydraulic control one-way valve 2, a valve seat, etc. to control the pressure of the system. And a hydraulic control one-way valve 2 is adopted to maintain the pressure of the oil cylinder 4. The moving direction of the piston is controlled by the electromagnetic directional valve 1. The positive and negative rotation of the oil motor is controlled by the electromagnetic directional valve 1 in a reversing way, so that the forward and backward movement of the plate pulling device is met.
When in a compression state: the motor 16 and the motor I15 drive the plunger pump 19 and the plunger pump I14 to operate, oil is supplied to the oil cylinder 4, the piston rod is driven to move through oil pressure, the movable pressing plate is driven to press the filter plate, the power supply of the motor 16 and the motor I15 is controlled through the electric contact pressure gauge 3, the oil pressure is supplied within the setting range of the electric contact pressure gauge 3, the power is cut off when the range is exceeded, the motor 16 and the motor I15 stop running when the power is cut off, and the pressure is controlled through the mutual matching of the hydraulic control one-way valve 2 and the overflow valve. When the pressure is reduced to a certain value, the electric contact pressure gauge 3 sends an electric signal to control the electromagnetic conversion valve 1 and the motor I15 to operate, the motor 16 does not receive the signal and does not operate until the pressure exceeds the range, and the operation is stopped, and the process is circulated.
In the unclamped state: when the loosening is started: the electromagnetic directional valve 1 and the motor I15 are electrified, low-pressure oil is supplied to the oil cylinder 4 through the overflow valve III 13 and the hydraulic control one-way valve 2, the piston rod begins to retreat, and the electromagnetic directional valve 1 and the motor I15 are electrified when the pressing plate reaches a fixed position.
