Automatic Hydraulic Door Closer - Ya Ji Builders Hardware
The basic components of the door closer include support guide, transmission gear, reset spring, check valve, rack and pinion plunger, throttle spool and shell. When the door opens, the connecting rod drives the transmission gear to rotate, compressing the spring and hydraulic oil. When the door closes, the spring releases energy and pushes the door to close, and at the same time, the hydraulic oil realizes the buffering effect through the throttle spool to control the closing speed. There are various types of door closers, including externally mounted and embedded door top closers, embedded door center closers, door bottom closers (floor springs) and vertical door closers. They are widely used in commercial and public buildings. Contact us today to learn more about how automatic hydraulic door closers can improve your space!
