How does an Air Jack Work

Editor:Lituo Machinery │ Release Time:2024-06-14 

An air jack is an Astonishing tool that uses compressed air to lift big stuff easily. It's valuable for fixing cars, setting up industrial gear, and saving people in emergencies. Let's dive into the coolness of air jacks!

1. Working principle of air jack

The working principle of an air jack combines gas compression and hydraulic transmission. In simple terms, it uses compressed air to drive a hydraulic pump, pressurize oil into the cylinder, and let the piston go up so that heavy objects can be lifted. Here are the detailed operation steps:

Connect the air source, such as an air compressor. Once the air source is started, the compressed air will flow into the jack along the pipe and start working.

Then, this compressed air will enter a pneumatic motor to make it rotate. This rotating motor will drive the hydraulic pump to extract and pressurize the hydraulic oil in the tank.

Next, this pressurized hydraulic oil will enter the cylinder through the pipe, pushing the piston up. As the piston rises, the rod or platform of the jack also increases, allowing heavy objects to be lifted.

When the weight is lifted to the appropriate height, the hydraulic system will use a check valve or locking device to maintain pressure to ensure that the weight can be firmly stopped at the lifted position.

To lower the weight, just run the pneumatic motor in reverse or release the pressure of the hydraulic oil, let the hydraulic oil flow back to the tank, the piston drops, and the jack will slowly lower the weight.

2. Components of the air jack

The air jack, this powerful tool, consists of a series of linchpin components that work together to show astounding lifting capabilities. One of the cores is the pneumatic motor, which uses compressed air as a power source to drive the hydraulic pump to operate efficiently. The hydraulic pump is a master of energy conversion, converting power into high-pressure oil flow, pushing the piston in the cylinder up, thereby achieving precise lifting of the weight.

The cylinders in the design are more than just ornaments, they take on the important role of lifting weights. It's a testament to the jack's remarkable load-bearing ability and unwavering durability. Then there's the control valve - the brains behind the operation. It deftly manages the flow and pressure of the hydraulic oil, ensuring that everything moves as smoothly as possible.

Connecting the intake and exhaust pipes are like lifelines, constantly transmitting compressed air and properly discharging exhaust gas. The oil tank silently guards the hydraulic oil to ensure the stability and long service life of the system. Each component performs its duties conscientiously in its position and together builds a robust and reliable airjack system.

3. Operation steps of an air jack

If you want to use the air jack smoothly, you have to follow this routine:

Check it first:

See if all the parts of the jack are in good condition, especially whether the connection between the intake pipe and the oil cylinder is tight.

Make sure the air source pressure you use is sufficient so that the jack will not break down due to insufficient air.

Find a place to put the jack firmly to avoid shaking when lifting things.

Connect the air source:

Connect the air pipe to the jack and your air compressor or other equipment that can supply air.

Check if there is any leakage at the connection.

Start lifting things:

Turn on the air source, start the air compressor, and turn the air motor.

Move the control valve to allow the compressed air to enter the jack, initiating the hydraulic pump to start working, causing the oil to flow into the cylinder, and prompting the piston to push upward.

Keep adjusting the control valve until the weight is lifted to the height you want.

Stabilize the weight:

Once it is lifted, close the control valve to keep the hydraulic system under pressure to prevent the weight from sliding down.

You can also get a mechanical lock or a check valve to make the weight more stable.

Put down the weight:

To ensure the weight lands safely, we must slowly release the oil pressure. The piston should descend steadily to prevent things from being smashed or accidents.

After the work, remember to turn off the air and unplug the air intake pipe. Clean the jack, clean the surrounding area, and check whether all parts are working well.

4. Precautions for use

When using an air jack, you have to pay attention to a few things:

Safety first: Don't forget to read the instructions before you start, follow the rules, and don't make any trouble.

Maintenance is essential: Check the jack regularly, paying unusual attention to the hydraulic and pneumatic components to ensure proper functionality. Remember to change the oil periodically and clean the garbage in the tank and pipes.

When lifting objects, ensure the weight is within the jack's capacity and not overweight. Overloading the jack can cause it to break down, and this could lead to a major accident.

Adapt to the environment: If it is used in extreme weather, such as too hot, too cold, or wet places, you must pay special attention to its working condition and not let these external factors affect its efficiency and safety.

As an efficient and convenient lifting tool, air jacks are widely used in various fields because of their unique working principle and superior performance. Understanding its working principle and correct operation method can better play the role of air jacks, ensure work safety, and improve efficiency.
