HFP AIR PNEUMATIC PUMP

A pneumatic hydraulic pump uses compressed air as its power source to generate hydraulic pressure. Here’s how it works- Air Input- Compressed air enters the pump through an inlet. Drive Mechanism- The air drives a piston or diaphragm within the pump, which, in turn, pressurizes hydraulic fluid. Fluid Pressurization- The fluid is pressurized and sent through high-pressure hoses to the connected tool (e.g., a torque wrench). Pressure Regulation- An adjustable regulator controls the air input to modify the hydraulic output pressure, ensuring precise torque delivery. These pumps are ideal in environments where compressed air systems are readily available.

Hydraulic pumps themselves do not produce torque they generate hydraulic pressure, which tools like hydraulic torque wrenches convert into torque. Pressure- Most hydraulic pumps operate at 10,000 PSI (pounds per square inch). Torque Output- The hydraulic wrench converts this pressure into torque, ranging from 100 Nm to over 50,000 Nm, depending on the wrench's design and application. The torque requirement depends on the bolt size, material, and application specifications.

A pneumatic torque wrench operates on the principle of compressed air power conversion into rotary motion to apply precise torque. Air Supply- Compressed air drives a high-speed motor. Gear Reduction- A planetary gear system reduces the motor’s speed, increasing torque output. Torque Control- A regulator or shut-off system ensures accurate torque application by controlling the air pressure and tool operation. Reaction Arm- A reaction arm absorbs counterforce, stabilizing the tool during operation. This design makes pneumatic torque wrenches efficient, precise, and well-suited for heavy-duty bolting applications.
