Pneumatic Jack Mean?
Pneumatic jacks are powered by compressed air and are used for lifting and positioning heavy material and machinery effortlessly. Pneumatic power turns electric power into mechanical power with the help of compressed air. The compressed air transfers the force for the purpose of lifting, pushing, or moving of heavy components.
Pneumatic jacks are used in the trenchless industry for the purpose of lifting heavy pipes, and positioning them during the installation process. Pneumatic tools such as jackhammers and jacking systems are also used in other facets of the construction industry. Pneumatic systems are easy to use and are economical because ordinary air is primarily used.
Trenchlesspedia Explains Pneumatic Jack
Pneumatic Jacks in Trenchless Operations
Pneumatic jacks make lifting and placement of heavy pipes and casings into position easier. They can also be used for the maintenance of heavy machinery such as for repair work and changing of parts of drilling rigs and cranes.
When working under heavy machinery, the machinery has to be lifted and held in place for the repair crew to get below and work. Pneumatic jacks are reliable and easy to operate and maintain as they use available air that can be drawn from the atmosphere and purified via a filter; it is also easily compressible.
The air for the pneumatic jack can be directly derived from the atmosphere and can release it back to the atmosphere when changes have to be made. This makes the operation of the pneumatic jack quick compared to hydraulic systems where the oil or fluid has to be routed back to the reservoir. Air-pressure powered tools are usually used for maintenance of valves and flanges as the pressure is more controllable.
Components and Working
Pneumatic systems typically consist of a pneumatic cylinder, compressor, jack, and a control unit. To make the air perform better, some of the water vapor is removed and a small amount of atomized oil is added. The compressor compresses the air and passes it to the pneumatic cylinder fitted with a piston, where the change of force takes place from electrical power to mechanical motion.
The electrical power is controlled and supplied from the control unit with a solenoid valve. The compressed air seeks the easiest exit route and exerts a huge force on the face of the piston. The load can be moved or lifted depending on the type of jack being used. Pneumatic powered jacks and other pneumatic systems are fast, work better with hand-driven equipment, and are cost-effective.
