Pneumatic balancer is a machine that utilizes the principles of aerodynamics to achieve a weightless state of an object, also known as a pneumatic balance crane.
It is powered by gas and can balance the gravity of objects, causing heavy objects to reach a suspended state.
The principle of a pneumatic balancer is as follows: under normal air supply, the pneumatic directional valve is in the on state.
When lifting with no load, the gas sequentially passes through the air source, filter, and manifold to reach the no-load balance pressure reducing valve, shuttle valve, and finally to the executing cylinder.
The gas pressure inside the cylinder is controlled by the no-load balance pressure reducing valve. At the same time, the air pressure reaches the micro air storage tank, spring return directional valve, and one-way throttle valve.
When the load is lifted, press and hold the button, and the spring reset directional valve is in the open state.
The gas passes through the air source, filter, manifold, spring reset directional valve, precision pressure reducing valve, and one-way throttle valve in sequence to reach the micro air storage tank and the actuator cylinder.
When the object rises, release the button, and the spring return directional valve closes. At this time, the pressure value in the air storage tank and the actuator cylinder is balanced with the load.
At this point, the operator can use micro operating force to carry the object up and down throughout the entire process.
