The lift pin is located within the suction valve cover. Its job is mechanical intervention. When a cylinder needs to be unloaded (turned off to save energy or match load demand), the lift pin physically descends and props open the suction valve plate.
The lift pin and spring are two components that work together to control the movement of the compressor's valve plate. The lift pin is a cylindrical pin that connects the valve plate to the compressor's crankcase, while the spring is a coil spring that surrounds the lift pin. mycom compressor lift pin and spring
In the world of industrial refrigeration, reciprocating compressors are renowned for their durability and sophisticated capacity control. At the heart of this system lies a small but critical duo: the lift pin and spring . These components are the physical bridge between the compressor’s hydraulic unloader and its suction valves, allowing the machine to adjust its output to match the cooling load.
