　　Working principle

MYCY14-1B定级变量柱塞泵

　　The main body (see structural section) is driven by the transmission shaft to rotate the cylinder body, causing seven evenly distributed plungers on the cylinder body to rotate around the centerline of the transmission shaft. The sliding shoes in the column sliding component are pressed onto the variable head (or swash plate) through the central spring. In this way, the plunger moves back and forth with the rotation of the cylinder body, completing the oil suction and pressure actions.

This type of pump relies on internal control (or external control) to manipulate the variable mechanism through oil pressure. The pressure regulation range of this pump is relatively small. After the oil pressure generates a variable between 3 and 4 Mpa, the flow rate quickly decreases to the required high-pressure flow value. This type of pump is actually equivalent to a high and low pressure combination pump, and the driving power selection of the pump can be calculated according to the power selection method of the pressure compensation variable pump.

The high-pressure oil from the main body enters the lower chamber (d) of the lower flange. When the spring force is greater than the hydraulic pressure acting on the area at the lower end of the push rod, it pushes the variable piston downward, increasing the flow rate of the pump. When the hydraulic pressure acting on the lower end area of the push rod is greater than the force of the spring, the variable piston moves upwards, causing a decrease in pump flow.

When adjusting the variable characteristics, adjust the adjusting sleeve according to the required flow and pressure change range, so that the flow at the final stage pressure of the pump will not change, and then adjust the adjusting screw to make the initial pressure meet the requirements when the pump flow just changes.
