Air hydraulic pump working process

An Air Hydraulic Pump is a device that uses compressed air to generate power and operate hydraulic systems. The working process of an air Hydraulic Pump can be described as follows:

1. Compressed air supply: The pump is connected to a source of compressed air, such as an air compressor. The compressed air is typically supplied at a pressure of around 80-120 psi.

2. Air motor: The pump contains an air motor that converts the energy from the compressed air into mechanical energy. The air motor consists of a piston and cylinder arrangement, where the compressed air is directed onto the piston, causing it to move back and forth.

3. Intake stroke: During the intake stroke, the piston moves away from the cylinder head, creating a partial vacuum in the cylinder. This causes atmospheric pressure to force hydraulic fluid into the cylinder through an intake valve.

4. Compression stroke: During the compression stroke, the piston moves towards the cylinder head, compressing the hydraulic fluid. This increases the pressure of the hydraulic fluid, which is then directed towards the hydraulic system through an outlet valve.

5. Hydraulic system operation: The high-pressure hydraulic fluid generated by the pump is used to operate various hydraulic components, such as cylinders, motors, or tools. The hydraulic fluid is directed to these components through hydraulic lines or hoses.

6. Return stroke: After the compression stroke, the piston moves back to its original position, creating a partial vacuum in the cylinder again. This allows the intake valve to open, and the cycle repeats as the pump continues to operate.

Overall, the air hydraulic pump uses compressed air to create mechanical energy, which is then used to generate high-pressure hydraulic fluid for operating hydraulic systems.
