Chengdu thermal insulation door, Chengdu lift gate

pass through door
1、 The electric sliding through door can be divided into upward sliding type, vertical lifting type and sectional lifting type, depending on the size of the door top space. The torsion spring is balanced and the electric lifting is opened.
2、 The sliding through door structure consists of the following parts:
1、 door plank ：
The door panel is specially made Aluminum profile The frame frame (color optional) is internally inlaid with transparent polycarbonate plates (the thickness of the plate body is 3mm-5mm).
The thickness of finished door plate is generally 40mm, and the length of reinforcing rib is also 40mm. (Profile thickness: 1.5~3.0mm).
Other types of door panels can be added as required: the door panel adopts double layers colour steel The board is filled with rigid polyurethane foam inside, and the thickness of the board body is generally 40mm.
The bottom of the door panel is provided with an EPDM rubber sealing strip, and an air bag is arranged in the sealing strip.
2. Hardware accessories:
The door connecting hinge is made of hot galvanized cold rolled steel plate by stamping. Material thickness δ=2mm, galvanized thickness greater than 28mm. The guide rail is a special guide rail for 3-inch industrial doors made of δ=2mm hot-dip galvanized steel plate by rolling; The cross section of the guide rail is provided with an anti release hook to ensure the smooth operation of the wheel in the guide rail; The guide rail guard plate is made of δ=2mm hot galvanized steel plate by rolling. The guard plate is equipped with slots for door side sealing rubber and mounting holes connected with the guide rail; The guide wheel is specially used for supporting the guide wheel. The guide wheel is made of wear-resistant nylon and contains roller bearings, which ensures smooth operation and no noise.
The other hardware parts are made of hot galvanized steel plate, with accurate size and good interchangeability.
3. Balance system:
The liftgate is balanced by torsion spring, which is designed and manufactured by professional spring factory according to the calculation of door load, so that the balance can reach a better state. The torsion spring is made of high-quality 60si2MnAz spring steel to ensure a service life of more than 30000 cycles. Surface blackening and rust prevention treatment.
The standard liftgate adopts cylindrical rope sheave. The shaft rod adopts hot-dip galvanized steel pipe, and the two shaft ends are solid round steel.
The safety factor of lifting steel wire rope is more than 5 times of the door weight, and the steel wire rope fracture is set on the door plate to ensure the safe operation of the door plate.
3. Motor and control:
