Plunger/Element

Product description

Piston is one of the common components in mechanical, hydraulic or pneumatic equipment, widely used for the transportation, control and regulation of liquids or gases. A plunger is usually cylindrical in shape and has sealing properties. It is used to push the flow of fluid or gas during operation, or to achieve functions such as motion and transmission. According to their different uses, plungers can be divided into different types such as hydraulic plungers, pneumatic plungers, pump plungers, etc.

Structural composition

The structural design of the plunger varies depending on different application scenarios and requirements, but generally includes the following main components:

1.Piston body:
The core component of a plunger is usually made of materials such as steel and aluminum alloy, and has the characteristics of wear resistance, compression resistance, and corrosion resistance.

3.Spring:
In some applications of plungers, springs are used to provide the necessary reaction force, helping the plunger automatically return to its original position when not in use, ensuring that the system can operate normally.

5.Slide and guide components:
The plunger usually needs to move in a specific guide groove, and the slide and guide are used to reduce the offset during plunger movement and ensure stable plunger movement.

2.Sealing device:
To prevent fluid or gas leakage, plungers are usually equipped with sealing devices such as seals, O-rings, lip seals, etc.

4.Drive device:
The movement of the plunger generally requires an external driving system. Hydraulic plungers are usually driven by hydraulic pumps, pneumatic plungers are driven by compressed air, and plunger pumps require power equipment such as electric motors to provide driving force.

Application scenarios

Pistons are widely used in many industrial fields, and their main application scenarios are as follows:

1.Hydraulic system:
The plunger is a core component in hydraulic systems, widely used in equipment such as hydraulic pumps, hydraulic motors, and hydraulic cylinders. Hydraulic plungers bear pressure and transmit mechanical energy through contact with oil, and are used in industries such as construction, metallurgy, mining, aerospace, etc.

2.Pneumatic system:
Pneumatic plungers are used in pneumatic systems to push gas flow and achieve pneumatic drive. Pneumatic plungers are widely used in fields such as automated production lines, robots, and pneumatic tools.

3.Fuel injection system:
In fuel injection pumps for internal combustion engines such as automobiles, ships, and diesel engines, plungers are used to regulate the amount and pressure of fuel injection, ensuring the combustion efficiency of the engine, reducing emissions, and improving power output.

4.Pump equipment:
Piston pumps are widely used in industries such as chemical, pharmaceutical, and food. The plunger pump delivers fluid through the reciprocating motion of the plunger, making it particularly suitable for high-pressure and low flow applications.

5.Liquid transportation:
In oil fields, chemical plants, sewage treatment plants and other occasions, plunger pumps and plunger driven conveying equipment are widely used for the transportation of liquids. Especially in environments that require sealing, pressure resistance, and high temperature, plunger equipment can maintain stability and long-term operation.
