Air shock absorber drum airbag

Basic information of the product

Product name: Fuel pump

Brand: Dismantling parts

Installation position: Fuel system

OE number: 1643201025

Applicable vehicle model: Mercedes Benz

Product details

Location: Located inside the vehicle's fuel tank, immersed in fuel. ‌

Composition: The electric gasoline pump is mainly composed of an electromagnetic drive structure and a fuel supply structure. ‌

Working principle: The fuel pump works during start-up and engine operation. If the engine stops and the ignition switch is still on, the control module will turn off the power to the fuel pump to avoid accidental ignition. Its working principle is mainly based on centrifugal force. ‌

Importance: The fuel pump is one of the basic components of the fuel injection system in electronic fuel injection vehicles and is crucial for the fuel supply system of the vehicle.

We also provide fuel pump of BMW, Mercedes Benz, Volkswagen, Range Rover, Maserati, Audi, Volvo and other models of cars.

The core function of shock absorber airbags is to use air pressure to cushion vibrations, improve equipment stability and safety, and optimize both adjustability and comfort

1. Core function: air pressure buffering and vibration control

Absorb impact energy
 

By utilizing the elastic and stretchable properties of inflatable rubber airbags, mechanical vibration kinetic energy is converted into changes in air pressure, effectively reducing impact forces.

For example, when a racing car is driving at high speed, the airbag can quickly respond to the movement of the inner rod, avoiding unstable vibration caused by bubbles in hydraulic oil. ‌

Eliminate the issue of 'empty travel'

In intense sports scenarios such as racing cars or industrial vibration tables, the high-pressure gas inside the airbag can prevent the formation of a vacuum area below the piston, ensuring the continuity of damping during the compression and rebound stages of the shock absorber, significantly improving shock absorption efficiency.

2. Application advantages
 

Multi scenario adaptability
In the industrial field, it is used for equipment such as vibration tables and paper making machinery. By adjusting the air pressure to match different vibration intensities, it extends the service life of the equipment and improves testing accuracy. ‌
 

Transportation: widely used in trucks (such as Auman and Volvo) and high-end passenger cars (such as Porsche Cayenne), balancing load capacity and driving stability. ‌
 

Performance optimization
Nonlinear stiffness: can automatically adjust the natural frequency according to the load to maintain stability (such as machine tool damping). ‌
Environmental protection and energy conservation: reduce component wear and fuel consumption, and lower maintenance costs. ‌

3. Technical features

Oil and gas separation design
By isolating gas and hydraulic oil through airbags, vibration noise caused by bubbles in traditional shock absorbers can be avoided, especially suitable for precision instruments. ‌
 

High adjustability
Combining control valves to achieve working height adjustment, meeting different structural requirements (such as pipeline equipment sealing or vehicle suspension adjustment). ‌
