YD00013056 PUMP PISTON For HITACHI ZX70-5G ZX70-5A ZX85US-3 K7SP36 K7V28

Piston pump is a hydraulic pump composed of piston, pump body, valve and transmission mechanism. The specific structure includes: piston: it is the main working part of piston pump, and it is responsible for circulating compressed liquid. Piston is usually made of high-strength aluminum alloy, titanium alloy and other materials, which has good corrosion resistance and wear resistance. Pump body: it is the main part of piston pump, and its internal space is divided into two parts: liquid inlet chamber and liquid outlet chamber. Pump body is generally made of cast iron, aluminum alloy and other materials, with high strength, compressibility and wear resistance. Valves: A series of valves are installed on the piston pump, such as liquid suction valve, liquid pushing valve and pressure control valve. These valves control the flow direction, flow rate and pressure of the liquid, and ensure the working efficiency and safety of the pump. Transmission mechanism: composed of driving motor, reducer, connecting rod and other parts, its function is to convert the power provided by the motor into the reciprocating motion of the piston in the pump body through the connecting rod, so that the liquid can form pressure and flow.

Piston pump is also called electric reciprocating pump. The pump piston is one of the core components of the pump, and its main function is to realize the suction and discharge of liquid through reciprocating motion. Pump piston is usually made of metal or other corrosion-resistant materials, which can work stably in high pressure and high temperature environment. The working principle of pump piston is to realize the suction and discharge of liquid through reciprocating motion. When the piston moves upward, the water inlet valve opens and the liquid enters the pump cylinder; When the piston moves downward, the liquid is pressed out of the pump cylinder and discharged through the water outlet pipe. This periodic movement enables the liquid to be continuously sucked and discharged, which can be divided into single cylinder and multi-cylinder from the structure, and is characterized by high lift. Suitable for conveying oil emulsion without solid particles at room temperature. Used for water injection, oil injection and oil production in oil fields and coal seams; Power pump of hydraulic press, hydraulic sand cleaning, ammonia liquid transportation in fertilizer plant, etc. If the overcurrent component is stainless steel, it can transport corrosive liquid. In addition, according to the different structural materials, it can also transport high-temperature tar, mineral mud, high-concentration mortar and high-viscosity liquid.

Piston pump is a commonly used booster pump, which is composed of piston and cylinder. It is widely used in hydraulic fluid conveying system to increase the pressure of fluid. Piston pump can suck in and squeeze out fluid by changing the relative displacement between piston and cylinder. Piston pump is suitable for hose pump and closed shaft seal pump. According to different construction structures and connection methods, piston pumps can be divided into three types: single piston pump, double piston pump and multi-piston pump. Piston pump is mainly used in hydraulic system, which can realize the delivery of hydraulic fluid and change the pressure and flow of fluid to meet the requirements of the system. Piston pumps can be widely used in hydraulic systems of automobiles, machine tools, ships, electric power, metallurgy and other industries to drive and control the operation of various actuators, such as hydraulic cylinders and hydraulic motors. Piston pumps can also be used in various hydraulic oil systems, such as tractors, excavators, cleaning equipment, hydraulic wrenches, etc., to adjust the pressure and flow of hydraulic oil. Piston pump can also be used in hydraulic transmission devices, such as hydraulic transmission vehicles, hydraulic motors, hydraulic drive vehicles, etc., to realize pressurization and control of hydraulic system. Piston pumps can also be used in hydraulic control systems, such as hydraulic control valves, hydraulic control cylinders, etc. Through piston pumps, pressure adjustment and flow adjustment of hydraulic control systems can be realized.
