The AT180926 hydraulic pump is a plunger pump. Its working principle is based on the volume change principle. Through the reciprocating motion of the plunger in the cylinder, the size of the sealed volume is changed, thereby achieving the oil suction and oil pressure processes. The specific working principle is as follows:
Oil suction process: When the plunger moves outward from the cylinder, the volume inside the cylinder increases, creating a vacuum. At this time, the pressure in the oil suction chamber is lower than that in the oil tank. Under the action of atmospheric pressure, the hydraulic oil in the oil tank is sucked into the pump through the oil suction port.
The oil compression process: When the plunger moves inward within the cylinder, the volume inside the cylinder decreases, the hydraulic oil is compressed, and the pressure rises. When the pressure reaches a certain value, the oil discharge chamber opens, and the high-pressure hydraulic oil is squeezed out of the pump and enters the pressure pipeline of the hydraulic system.
Cycle process: The drive shaft keeps rotating, driving the plunger to reciprocate continuously. As a result, the hydraulic pump will repeatedly perform oil suction and pressure actions, thereby converting mechanical energy into hydraulic energy and providing a continuous and stable supply of pressure oil for the hydraulic system.
