Trade Assurance Yuken Piston Pump A10-F-R-01-C-K-10 A10-F-R-01-B-K-10 Series A56-L-R-04-H-K-32 Without Foot Rest

YUKEN plunger pump is generally composed of main parts such as cylinder block, oil distribution plate, plunger and swashplate. There are several plungers in the cylinder, and the plungers are arranged axially, that is, the center line of the plungers is parallel to the axis of the transmission shaft, so it is called an axial piston pump. But it is also different from the reciprocating piston pump, because its plunger not only does reciprocating movement in the pump cylinder, but also the plunger, pump cylinder and swashplate have relative rotary movement. The plunger contacts the swashplate with a spherical end. There are high and low pressure moon shaped grooves on the oil distribution plate, which are separated from each other by partition walls to ensure a certain degree of sealing. They are respectively connected with the oil inlet and outlet of the pump. There is an inclination angle between the axis of the swashplate and the axis of the cylinder block

According to the working principle of YUKEN plunger pump, when the motor drives the transmission shaft to rotate, the pump cylinder and plunger rotate together, and the plunger head always keeps in contact with the swashplate. Since the swashplate is at an angle with the cylinder block, the plunger will reciprocate in the pump cylinder when the cylinder block rotates. Take the next plunger in Figure l-40 as an example. It turns from 0 ° to 180 °, that is, to the position of the upper plunger. The volume of the plunger cylinder gradually increases, so the liquid is sucked into the oil cylinder through the oil suction port a of the oil distribution plate; When the plunger is turned from 180 ° to 360 °, the volume of the plunger cylinder decreases gradually, so the liquid in the cylinder is discharged through the outlet of the oil distribution plate. As long as the drive shaft rotates continuously, the pump will work continuously.
