They have many uses, the most important of which is to make the door closed by itself, to limit the spread of fire and ventilation within the building.
Q:How does the door closer work?
The door closer is a similar spring-like hydraulic pressure, when the door is opened after the release by compression, the door automatically shut, like the role of the spring door, you can ensure that the door is opened, accurate and timely closure to the initial position The
Q:What oil is used in the closer
Requirements include: 1) whether the need to open the door after the automatic stop function; 2) damping buffer function - quickly open the door to a certain position after the damping buffer, and the damping buffer force and range can be adjusted according to the use of self-use; This function is used to prevent the door quickly when the door or lock the wall, or emergency escape To prevent people in the fast open when the weight loss and leaning forward. 3) delay the slow closing - the door from the door to the maximum position began to slow down slowly, according to the requirements of stepless adjustment. Suitable for use in frequent and crowded places, especially hospitals, with the elderly, children and disabled access and access to the use of the door. 4) Closing force can be adjusted - can be used in the door and the door wide range of different doors to install, and because of environmental reasons to close the door more resistance.

Adjust the distance between the connecting rod and the hinge centerline of the door, the smaller the closing force of the door closer, the greater the strength.     3) Determine the position of the mounting screw according to the position indication on the mounting plate, then drill and tapping.     4) Install the door closer with screws.     5) Install the fixed connector.     6) Install the drive plate with screws.     7) Adjust the adjustment lever to 90 ° to the door frame, and then connect the connecting rod to the drive plate.     8) Do not forget to install a plastic cover, it can be used to catch the closed door leakage of hydraulic oil.     9) After installation, check whether the fixing screws are fastened or loose or not. Open the door to the maximum door position, check whether the hinge arm of the door closer is rubbed or rubbed against the door or door frame.     Close the door closing speed     10) Adjust the closing speed of the door closer as needed. Usually the door closers have two speed control (throttle spool) screws. The upper adjustment screw is the first section of the closing speed adjustment screw, and the lower adjustment screw is the second speed (usually 10º) closing speed adjustment screw.     C, the use of door closers and maintenance, repair     The newly installed door closers should be used for one week to about 10 days, and all screws should be checked and re-tightened again.
