Technical parameters of electric rolling shutters for electric rolling shutter doors

The motor is hidden in the rolling tube. The rotation of the motor drives the transmission shaft to rotate, thereby realizing the lifting and lowering of the roller blind. When rising, the curtain is wound on the reel, and when falling, the curtain slides down the inside of the guide rail. The curtains can be raised, stopped, and lowered through the control of the remote control. There is also a power-off manual release system, and the rolling shutter door can be raised and lowered through the manual rocker in the event of a power outage. Let's talk about the relevant knowledge of electric roller shutters with the editor.

"Electric rolling shutter" is an electric rolling shutter mechanism powered by a tubular motor. Its operation only requires turning the power switch, which is easy to operate, quiet and stable, and is an upgraded product of manual roller blinds. The motor is directly installed in the aluminum alloy rolling tube, which not only reduces the volume of the curtain box and the force transmission link, but also avoids the influence of the outside world on the motor, and increases the reliability of the mechanism. The rolled tube is made of high-quality aluminum alloy material, which has high strength and is not easy to deform. The surface is anodized to prevent aging and corrosion. The installation bracket is made of high-strength alloy steel, which has high bending and shear strength, ensuring the safety and reliability of the installation and use of the mechanism.

Technical parameters of electric roller shutters

1. Material: The curtain surface is made of inorganic refractory cloth, aluminum silicate fiber blanket, radiation protection cloth and decorative cloth sewn with high-temperature threads It is made of galvanized steel strips on both sides to ensure the wind resistance of the curtain. The bottom beam is made of galvanized steel, with a thickness of 1.2mm and no seams. The reel is made of welded steel pipe, specification 165, thickness 2.0mm, except for the pipe wall. Rust and anti-corrosion; guide rail: steel galvanized plate thickness 1.2mm, made of split composite. The sliding surface of the guide rail should be smooth and straight, the straightness should not be greater than 1.5mm per meter, and the straight line of the entire length should not exceed 0.12. The top of the guide rail should be arc-shaped, and its length should exceed the opening by at least 75mm. Guide rails with smoke-proof performance must have smoke-proof devices, and the materials used should be non-combustible materials. The smoke-isolating device and the surface of the roller shutter should be evenly and tightly fitted. It should not be less than 80; the gap between the special fireproof rolling shutter door seat plate and the ground should not be greater than 20mm.

2. Control system functions: The roller blinds can be controlled independently and have manual functions. They are linked with the temperature fuse device and directly linked with the fire control room; smoke alarms are realized, and the roller blinds automatically drop to the ground 1.5- 1.8m height, delay 180 seconds (adjustable) and then turn off when falling. When an obstacle is encountered while descending, it can stop descending and ascend; it can achieve a single descent with smoke alarm and a second descent with temperature alarm, and can stop the second descent after the temperature alarm is eliminated, which can be converted into each other within one system. Comply with the requirements of standard 6.4.6; vertical opening and closing speed: not less than 2m/min. Its weight reduction speed should not be greater than 9.5m/s, and its average noise is 85dB.

3. Electrical functions: main power supply 50HZ, 380V, signal power supply 24V, power 0.37-2.2KW (the motor power is determined according to the size of the door opening); the special fireproof rolling shutter door should be equipped with a manual opening and closing device to prepare for interruption It should be used when electricity is used; it should have the performance of relying on the dead weight of the rolling shutter and have constant speed performance. The operating force of the manual quick release device should not be greater than 50N; the fire-proof rolling shutter door should use a fire power supply, and the power cord should be passed through a metal pipe and laid concealed. Fire protection measures should be taken; when there is no fire alarm, the roller shutter has basic manual and electric functions such as up, stop, and down, and the upper and lower limits are accurate and reliable.

Main types

First, according to the door material of the electric rolling shutter door, it can be divided into: European style rolling shutter door, inorganic cloth type, mesh type, aluminum alloy rolling shutter door and crystal rolling shutter door .

Second, from the types of special motors for electric rolling shutter doors: special motors for rolling shutter doors include: fire-proof rolling door machine, Australian rolling door machine, external rolling door machine, tubular rolling door machine, inorganic double-curtain rolling door machine , fast rolling door machine, etc. Electric rolling shutter doors using different special motors have their own characteristics, which depends on the needs of the customer.

Thirdly, there are many types of electric rolling shutter doors: according to the different uses of each user, there are silent types, noise reduction types, stainless steel rolling shutter doors, windproof, fireproof rolling shutter doors and crystal rolling shutter doors.

Maintenance knowledge of electric rolling shutter doors:

1. During the use of electric rolling shutter doors, try to keep the controller and voltage stable. It is prohibited to install it in a very humid environment. In addition, do not Open the remote control at will. If you find that there are wires entangled or knotted on the door, you should deal with them in time. Pay attention to whether the channel is blocked, preventing the door from descending. If an abnormal response occurs, stop the motor operation immediately.

2. Regularly check the up and down stroke switch of the electric rolling shutter door, add lubricating oil to the stroke controller to maintain normal and good operation. In addition, the operator manually controls the rolling shutter door, checks the operation of the device, and calibrates The position of the upper and lower travel switches ensures that the electric rolling shutter door is in the appropriate position when opening or closing. During the inspection process, it is strictly prohibited to prevent the electric rolling shutter door from rushing to the top or bottom or reversing. If an emergency occurs, the rotation should be stopped immediately and the power supply should be cut off.

3. It is best for operators to regularly check the manual switch and manual lifting decoration of the electric rolling shutter door to prevent the electric rolling shutter door from malfunctioning in an emergency or causing unnecessary safety accidents.

4. To keep the track running smoothly, clean the track of the electric rolling shutter door in time and keep the interior clean. The rolling shutter door motor and transmission chain should be regularly filled with lubricant, check the components in the control box and the switch control box, and tighten them. Wiring ports, fastening screws, etc., clean the dust and dirt in the control box, on the surface and on the buttons to prevent the buttons from getting stuck and unable to rebound.
