The plunger pump inputs fluid by reciprocating the plunger rod in the cylinder, thereby generating a pressure difference. The total reciprocating stroke L of the plunger pump plunger is constant and is determined by the lift of the cam. The amount of oil supplied per cycle of the plunger depends on the oil supply stroke, which is not controlled by the camshaft and is variable. The start time of oil supply does not change with the change of the oil supply stroke. Rotating the plunger can change the end time of oil supply, thereby changing the amount of oil supply. When the plunger pump is working, the cam on the injection pump camshaft and the plunger spring force the plunger to reciprocate up and down, thereby completing the oil pumping task. The oil pumping process can be divided into two stages: the oil inlet process and the oil return process.
Piston pump structure
The piston pump is mainly composed of two parts: the power end and the hydraulic end, and is equipped with a pulley, a check valve, a safety valve, a voltage regulator, a lubrication system, etc. The specific structure is as follows:
(1) Crankshaft: The crankshaft is one of the key components of this pump. It adopts an integral crankshaft type, which will complete the key step of converting rotational motion into reciprocating linear motion. In order to balance it, each crankshaft handle pin is 120° with the center.

(2) Connecting rod: The connecting rod transmits the thrust on the plunger to the crankshaft, and converts the rotational motion of the crankshaft into the reciprocating motion of the plunger. Its rod cross-section adopts an I-shaped, the large end is split, the bearing adopts a split thin-walled bearing form, and the small end bearing adopts a sleeve type, and is positioned by it.
(3) Crosshead: The crosshead connects the swinging connecting rod and the reciprocating plunger. It has a guiding function. It is closed-type connected to the connecting rod and connected to the plunger clamp.
(4) Floating sleeve: The floating sleeve is fixed on the machine base. On the one hand, it serves to isolate the oil tank from the dirty oil pool. On the other hand, it serves as a floating support point for the crosshead guide rod, which can increase the service life of the moving sealing parts.
(5) Machine base: The machine base is a load-bearing component for installing the power end and connecting the hydraulic end. There are bearing holes on both sides of the rear of the machine base, and a positioning pin hole connected to the hydraulic end is provided on the front to ensure the center of the slideway and the center of the pump head. A drain hole is provided on one side of the front of the machine base to discharge leaked liquid.
The primary function of a plunger pump is to convert mechanical energy input from an external source into pressurized energy via the prime mover. It transmits energy to the hydraulic system in the form of pressure or flow. Due to its capability to transport liquids at high pressures, the plunger pump is extensively used in various applications, including oil exploration and development, catalytic reactions in the petrochemical industry, liquid chromatography analysis, supercritical extraction, separation processes, atomic energy research, environmental science, process equipment, experimental setups, and the micro-delivery of various liquids.
