A Hydraulic Door Closer is a common household appliance, mainly used in our fire doors. Now many home renovations will use. But there are many types of Hydraulic Door Closer, so how do we choose them? Here follow me to see what kinds of door closers!
This is the list of contents：
Externally mounted door top closers
Embedded door top closers
Door bottom spring
Floor springs (floor closers)
An externally mounted Hydraulic Door Closer is equipped with a hydraulic buffer oil pump device, which allows the door to open and close automatically. Its main feature is that the door closes slowly, and no collision sound after closing, it can be used in schools, hospitals, office buildings, hotels, and other doors.
1. External mounted door top Hydraulic Door Closer does not apply to two-way opening doors.
2. Hydraulic Door Closer should be refilled with antifreeze oil after 1 year of use. When refueling, screw out the oil hole, you can refuel, and the oil will be full of screws tightened. The rest of the screws and sealing parts should not be screwed at will to prevent oil leakage.
The inline door top spring is composed of a hydraulic cushion spring installed on the door fan and a slide and slider installed on the door frame, as well as the coupling rod. Because the embedded door top Hydraulic Door Closer is installed in the door fan and door frame slot, so when the door is closed does not affect the appearance of the door. Embedded door top Hydraulic Door Closer is suitable for use on the door of high-grade hotel rooms.
The bottom door spring is composed of two parts. The upper part is the top shaft and the top shaft sleeve plate, and the lower part is the bottom shaft and the spring body. Its role is equivalent to the double spring hinge, which can make the door open and close automatically. When the door does not need to be closed automatically, the door can be opened to 90°. The door bottom spring can be used for spring wood doors or doors that open in both directions.
The floor spring is composed of two major parts. Its upper structure is the top shaft and the top shaft sleeve plate, and the lower structure is the rotary shaft and the base.
Floor spring not only can make the door automatically close, and run smoothly, with no noise but also can adjust the speed of the door automatically close. When the door opening angle is less than 90 °, the door and window can be closed automatically in both directions; when the door is opened to 90 °, the door can be fixed, this ground spring because the main structure is buried in the ground, can keep the door beautiful, mostly used in the doors of more advanced buildings.
The above is the analysis of the issue of what types of Hydraulic Door Closer, I hope you through the four-door closers can be a more detailed understanding of the type of Hydraulic Door Closer.
