Abstract: This paper mainly introduces the importance, working principle, type characteristics and wide application of hydraulic jack in automotive field. Through the in-depth analysis of hydraulic jack, the key role of hydraulic jack in automobile repair, maintenance and emergency rescue is expounded, which provides strong support for the development of automobile industry.

1. Introduction

With the rapid development of the automobile industry, the number of cars is increasing, and the repair and maintenance of cars are becoming more and more important. As an important vehicle maintenance tool, hydraulic jack plays an irreplaceable role in the automotive field. It can lift the car easily, providing convenient conditions for the repair and maintenance of the car.

2.The working principle of hydraulic jacks

Hydraulic jacks work mainly on PASCAL's principle. That is, the static liquid in the closed container, when one place is subjected to pressure, this pressure will be transmitted to all points in the liquid. In a hydraulic jack, pressure is applied to the small piston by manual or electric means, so that the hydraulic oil below the small piston produces pressure. Due to the incompressibility of the hydraulic oil, this pressure will be transferred to the large piston, so that the large piston produces a larger lifting force, lifting the car.

3. The type of hydraulic jack in the automotive field

(1) Vertical hydraulic jack

Vertical hydraulic jacks usually have a large lifting force and are suitable for various types of cars. It has compact structure, small space and convenient operation. The lifting height of vertical hydraulic jacks is generally higher, which can meet the maintenance needs of different models.

(2) Horizontal hydraulic jack

Horizontal hydraulic jacks are suitable for space limited occasions, such as the maintenance of the bottom of the car. Its flat shape makes it easy to carry and operate. The lifting force of the horizontal hydraulic jack is relatively small, but it is enough to meet the needs of general automobile maintenance.

(3) Shear hydraulic jack

The structure of the shear hydraulic jack is similar to scissors, and it is lifted by two crossed arm rods and a hydraulic system. The lifting height of the shear hydraulic jack is low, but the floor area is small, and it is suitable for low space operations, such as automobile tire replacement.

4. The application of hydraulic jacks in the automotive field

(1) Automobile maintenance

In the process of automobile maintenance, hydraulic jack is one of the essential tools. It can be used to lift cars to facilitate maintenance personnel to check and repair components such as car chassis, engine, transmission and so on. For example, when replacing car tires, brake pads, shock absorbers and other components, hydraulic jacks need to be used to lift the car up in order to operate.

(2) Car maintenance

Hydraulic jacks are also widely used in the field of automobile maintenance. For example, when carrying out maintenance work such as car chassis cleaning and lubrication, hydraulic jacks need to be used to lift the car up for better operation. In addition, when replacing car oil, filters and other components, it is also necessary to use hydraulic jacks to lift the car up for better operation.

(3) Emergency rescue

In the event of a car failure or accident, the hydraulic jack can be used as an emergency rescue tool. For example, when a car tire blows out or gets stuck in a difficult situation such as mud, a hydraulic jack can be used to lift the car up, replace the tire or perform a trapped operation. In addition, when the car is deformed in an accident, hydraulic jacks can also be used to lift the car for rescue operations.

5. The advantages of hydraulic jacks in the automotive field

(1) Large lifting force

Hydraulic jacks can produce a large lifting force and can easily lift various types of cars. This makes car repair and maintenance easier and faster.

(2) Easy to operate

The operation of the hydraulic jack is relatively simple, and it only needs to be lifted by applying pressure to the small piston manually or electrically. This makes car repair and maintenance much easier to use.

(3) Good stability

The structure of the hydraulic jack is stable, and it can keep the car stable when lifting the car. This makes car repair and maintenance work safer and more reliable.

(4) Strong applicability

Hydraulic jacks can be selected according to the needs of different models of different specifications and models, with strong applicability. This makes car repair and maintenance work more flexible and varied.

6. The use of hydraulic jacks in the automotive field precautions

(1) Choose the right hydraulic jack

Before using the hydraulic jack, it is necessary to select the right hydraulic jack according to the weight and maintenance needs of the car. If the selected hydraulic jack lifting force is insufficient, it may lead to unstable lifting of the car, and even dangerous.

(2) Correct use of hydraulic jacks

When using hydraulic jacks, it is necessary to operate in the correct way. First of all, you need to place the hydraulic jack on a smooth ground and ensure that it is in good contact with the car. The car is then gradually lifted up by applying pressure to the small piston either manually or electrically. In the process of lifting the car, it is necessary to pay attention to the working state of the hydraulic jack to ensure its stability and reliability.

(3) Pay attention to safety matters

When using hydraulic jacks, it is necessary to pay attention to safety matters. First of all, we need to ensure that the quality of the hydraulic jack is reliable and avoid the use of inferior products. Secondly, in the process of lifting the car, it is necessary to avoid personnel standing under the car to avoid danger. Finally, after using the hydraulic jack to complete the repair work, it is necessary to slowly lower the car and ensure that the various components of the hydraulic jack are restored to the initial state.

7. Conclusion

As an important vehicle maintenance tool, hydraulic jack plays an irreplaceable role in the automotive field. It has the advantages of large lifting force, easy operation, good stability and strong applicability, and is widely used in automobile repair, maintenance and emergency rescue. When using hydraulic jacks, it is necessary to pay attention to choosing the right product, correct operation and pay attention to safety matters to ensure that it can play the greatest role. With the continuous development of the automotive industry, the technology of hydraulic jacks will also continue to innovate and progress, providing more powerful support for the development of the automotive industry.
