High Efficiency Pump Plunger 090150-3050 Pump Elements Diesel Engine Spare Parts

A plunger is a common mechanical element that is typically used to achieve reciprocating motion in devices such as hydraulic systems, pumps, presses, internal combustion engines and cylinders. Plungers can be categorised according to their structure, purpose and principle of operation. The following are some of the common types of plungers and their functional applications:
1. Unidirectional plungers (single piston):

Functional applications: Unidirectional plungers are usually used in simple hydraulic systems or pressure mechanisms to generate reciprocating motion, such as manual hydraulic pumps, cylinder drive systems, and so on.

2. Bidirectional plunger:

Bidirectional plungers can be used for bi-directional transmission in hydraulic systems, such as hydraulic motors, bi-directional hydraulic pumps, and so on. Bidirectional plunger design can be achieved in two directions of reciprocating motion, and can produce greater thrust.

3. Piston pumps and piston motors:

Functional applications: Piston pumps and piston motors are hydraulic transmissions that use a piston as the main working element. They are usually used in engineering machinery, automotive hydraulic systems, oilfield drilling equipment and other fields, used to provide fluid power to achieve the conversion of hydraulic energy.

4. Plunger type internal combustion engine:

Functional application: Plunger type internal combustion engine is a kind of heat engine, through the combustion of fuel to make the plunger in the cylinder reciprocating motion, so as to drive the crankshaft rotation. This type of internal combustion engine is widely used in automobiles, ships, generator sets and other fields.

5. Plunger cylinder:

Functional application: Plunger cylinders are usually used in mechanical devices that require reciprocating motion, such as presses, injection moulding machines, hydraulic cylinders, and so on.

6. piston compressor:

Functional application: Plunger compressor is a device used for gas compression, widely used in refrigeration, air conditioning, industrial gas compression and other fields.

7. Other special applications:

In some special areas, can also be designed to use the plunger of special devices, such as syringes, high-pressure water jet cleaning equipment.

8. Plunger type high pressure pump:

Functional application: Plunger type high pressure pump is a device used to provide high pressure liquid, commonly used in hydraulic engineering, high pressure cleaning equipment, injection equipment and other fields. Through the reciprocating motion of the plunger in the pump body, the liquid will be compressed and output high-pressure fluid.

9. Plunger type automotive braking system:

Functional Application: In plunger type automotive braking system, the plunger is used as a key component of the brake. When the brake is triggered, the plunger is pushed, pushing the brake pressure plate against the brake disc by hydraulic pressure to achieve braking effect.

10. Plunger type hydraulic cylinder:

Functional Application: Plunger type hydraulic cylinder is a device used to generate linear motion, which is commonly used in the fields of construction machinery, metallurgical equipment, ships and so on. Through the control of the hydraulic system, the reciprocating motion of the plunger in the cylinder body to generate thrust, to achieve the movement or positioning of the workpiece.

11. Plunger injector:

Functional application: In some injection systems, the plunger is used as the driving element of the injector. Through the reciprocating motion of the plunger in the pump body, the liquid is compressed and ejected through the nozzle, commonly used in automotive fuel injection system, rocket engine injection system, etc..
