Plunger is a critical component used in fuel systems or hydraulic systems, primarily for generating high-pressure fluid (such as fuel or hydraulic oil) and delivering it to the system.

1.  Function
High-Pressure Generation: Generates high-pressure fluid through reciprocating motion in the pump chamber.

Fluid Delivery: Delivers high-pressure fluid to various components of the system.

Flow Control: Controls the flow rate of the fluid by adjusting the stroke or speed of the plunger.

2.  Structure
Plunger Body: Usually made of high-strength materials to withstand high pressure and wear.

Plunger Head: Fits with the pump chamber to form a seal, ensuring the generation of high-pressure fluid.

Spring: Used to control the reset of the plunger, ensuring the stability of its reciprocating motion.

Seals: Prevents fluid leakage, ensuring efficient system operation.

3.  Applications
Fuel Systems: Used in fuel injection pumps, high-pressure fuel pumps, etc., to ensure high-pressure fuel supply.

Hydraulic Systems: Used in hydraulic pumps, hydraulic cylinders, etc., to control the flow and pressure of hydraulic oil.

4.  Features
High Precision: Ensures accurate fluid control.

Durability: Capable of withstanding high pressure and wear environments.

Reliability: Guarantees long-term stable operation.

5.  Maintenance
Regular Inspection: Ensures no wear or damage.

Cleaning: Prevents clogging of the plunger or pump chamber by impurities.

Replacement: Timely replacement when reaching service life or upon damage.

6.  Common Issues
Wear: The plunger body and head may wear out after prolonged use.

Clogging: Impurities may cause clogging of the plunger or pump chamber.

Leakage: Aging seals may lead to fluid leakage.
