When sucking pulp, the pulp discharge check valve is closed, the pulp inlet check valve is opened, and the external pulp is sucked from the lower pulp inlet check valve due to the existence of pressure difference and negative pressure; when the slurry is discharged, the slurry inlet check valve is closed due to the effect of pressure, the slurry discharge check valve is opened, and the slurry is discharged from the upper slurry discharge check valve to the slurry discharge pipe. The technical scheme is that a pulp inlet check valve and a pulp outlet check valve are horizontally connected with a cylinder, a plunger extends into the cylinder, a sealing ring is arranged between the cylinder and the plunger, a high-pressure water pipe is connected to the cylinder close to the sealing ring, so that the high-pressure water enters a gap among the cylinder, the plunger and the sealing ring and is sprayed into the cylinder, the pulp is prevented from entering the gap, and the sealing ring, the plunger and the cylinder are prevented from being damaged by pulling. However, the equipment has the problems that the pulp inlet check valve and the pulp outlet check valve are tightly connected with the cylinder, no storage space exists between the pulp inlet check valve and the cylinder, and the pulp directly enters the cylinder from the pulp inlet valve and can seriously wear the cylinder, the plunger and the sealing ring; when the high-pressure sealing lacks water, the water quality is poor or the pressure is low, slurry enters a gap to damage a sealing ring, a plunger and a cylinder in a pulling way, water consumption and power consumption are consumed, wearing parts for configuring the high-pressure water pump are increased, and the concentration of conveyed materials is reduced by adding high-pressure sealing water.
The structure and working principle of the diaphragm slurry pump are seen in the figure 2, the hydraulic end of the diaphragm slurry pump comprises a slurry inlet pipe, a slurry inlet check valve, a slurry outlet pipe, a lower elbow pipe, a diaphragm chamber, a guide rod cavity, a cylinder, a sealing ring, a piston and a piston rod, the power end comprises a box body, a medium rod, a cross head, a connecting rod, a main shaft, a motor, a hydraulic station and a control system, the working principle of the pump is that the motor drives an eccentric wheel or a crankshaft of the pump to rotate through a belt or a speed reducer, the connecting rod, the cross head, the medium rod, the piston rod and the piston are pushed and pulled to enable the piston to reciprocate, and the hydraulic oil between the cylinder and the diaphragm drives the diaphragm in the diaphragm chamber to reciprocate, so that slurry suction or slurry discharge is generated. When sucking pulp, the pulp discharge check valve is closed, the pulp inlet check valve is opened, and the external pulp is sucked from the lower pulp inlet check valve due to the existence of pressure difference and negative pressure; when the slurry is discharged, the slurry inlet check valve is closed due to the effect of pressure, the slurry discharge check valve is opened, and the slurry is discharged from the upper slurry discharge check valve to the slurry discharge pipe. The hydraulic oil between the cylinder and the diaphragm is reduced or increased, so that the oil is supplemented and discharged by configuring a probe signal detection system, a PLC computer control system and a hydraulic station execution system.
