Firstly, the given design parameters obtained distribution on the radius of the diameter of the plunger and backhaul panel plunger size and the force and the empirical formula can draw the basic size of the slipper. Distribution radius in order to determine the valve plate on the inner seal oil, the main dimensions of the suction oil window. Shaft size to calculate the inner diameter of the cylinder, according to the distribution of the plunger and the cylinder wall thickness calculated cylinder diameter, stroke of the plunger to calculate the length of the cylinder, and then check the strength. Finally, the piston pump variable institutions by the line selection, as well as some of the parameters of the calculation, the final assembly of the piston pump.
