Description

Spacing hemisphere detachable plunger pump sloping cam plate Technical Field The utility model relates to the technical field of engineering machinery, in particular to a limit hemisphere detachable plunger pump swash plate. Background Plunger pumps are important devices in hydraulic systems for providing hydraulic power to actuators in the hydraulic system. The plunger pump is driven by a motor, and outputs a certain flow of hydraulic oil to the actuating element through the reciprocating motion of the plunger in the cylinder body, so that the actuating element can convert the pressure energy of the liquid into mechanical energy. Among them, the plunger pumps are generally classified into quantitative plunger pumps and variable plunger pumps. At present, a variable plunger pump is usually a variable axial plunger pump, the input flow of the variable plunger pump is variable, the input flow is small when the pressure is high, and the input flow is large when the pressure is low. The swash plate type plunger pump can change the pump output flow by changing the angle of the swash plate so as to meet the requirement of an actuating element. In practical application, the displacement of the plunger pump is continuously changed, the situation that the limit hemisphere or the reset spring is damaged possibly occurs, but the limit hemisphere is difficult to disassemble, and in most cases, the limit hemisphere can only be disassembled destructively, so that the repair or replacement cost is high. Disclosure of Invention The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the limit hemispherical detachable plunger pump sloping cam plate which has a simple structure and good effect. The utility model is realized by the following technical scheme that the swash plate of the plunger pump with the detachable limiting hemispheres comprises a swash plate, a through hole is formed in the bottom of a ball socket used for connecting the limiting hemispheres, a sealing spring seat is arranged in the through hole, and a hemispheric reset spring is arranged between the sealing spring seat and the limiting hemispheres. The swash plate is further provided with a boss, and the through hole is formed in the boss. The boss is arranged on one side of the swash plate away from the ball socket. The through holes are inclined through holes with the diameter of 5mm. The direction of the through hole is consistent with the direction of the hemispherical return spring. One end of the sealing spring seat is matched with the hemispherical reset spring, and the other end of the sealing spring seat is provided with a sealing ring. The sealing ring is a D-shaped sealing ring. The movable type plunger pump swash plate has the advantages that the movable type plunger pump swash plate with the limit hemispheres optimizes the structure of the swash plate, the through holes are formed in the bottom of the swash plate, the sealing spring seat is used for sealing, the spring position protection spring can be effectively fixed by the sealing spring seat, in addition, the movable type plunger pump swash plate with the limit hemispheres can be conveniently detached through the disassembly tool, the replaceability of the movable type plunger pump swash plate with the limit hemispheres is improved, the loss rate of parts is reduced, and the assembly efficiency is improved.
