The sluice gate is also called the curtain door, because the place is different so the call is not the same. In fact, it means the same thing. But there is a door called a sliding door, which is not the same product as the reel gate. What's the difference?
The main difference between the two gates of the roll gate and the sliding door is the main shaft of the curtain door (commonly known as the beam pipe). The rolling gate is connected by a lot of joint movable doors. In the fixed slipway, the door with upper and lower scrolls on the top of the door rotates up and down, which is suitable for all kinds of merchant shops. The principle of sliding door is to achieve follower balance by balancing system, and drive door body by external force (manual or electric) to operate in a suitable track system. It is suitable for all kinds of factories, logistics warehouses or special garage with high thermal insulation and sealing requirements.
In general, the installation process of the sliding door is required to be higher than the sluice gate, and the sliding door will increase the level. The principle is that it is connected in series with multiple joint movable doors, fixed in the slideway of the guide way, rotates on the top and bottom of the door, and rotates with the special motor to drive the central axis of the rolling curtain to achieve the rolling switch. When it rotates to the upper and lower limit of the motor, it stops automatically. To ensure the safety of the use of the sliding door, the category will also be equipped with a safety protection device.
The sliding lift door also uses the torsion spring balance system to balance the torsion spring designed and made according to the software of the door heavy load, so that the balance can reach the best state. The torsion spring material is made by selecting 60si2Mn imported spring steel to ensure the service life of more than 80000 cycles. Sliding doors with balance shaft 25.4 solid bar, which is provided with a torsion spring breakage protection device on the balance shaft, the torsion spring balance device can prevent fracture when the door fall; lifting rope round aluminum cylindrical rope wheel.
The safety factor of the hoisting rope is 5 times greater than that of the door weight, and the wire rope breakage is set on the door plate so as to ensure the safe operation of the door.
In summary, the sliding door is suitable for large industrial buildings, hangar, and garage. Its requirements are all industrial level. Therefore, the requirements for the manufacturing and installation are also higher.
