The electric roller shutter door is a door that is connected in series with multi joint movable door pieces. The starting is driven by the motor group. The roller shutter door is in a fixed slide and rotates up and down around the roller shaft above the door. Let's learn about the technical parameters of the electric roller shutter door. Jinan roller shutter door manufacturer will explain it to you.
1、 Material: the curtain surface is made of inorganic fire-resistant cloth, aluminum silicate fiber blanket, anti radiation cloth and decorative cloth through high-temperature sewing, and the two sides are clamped with galvanized steel strips to ensure the wind resistance of the curtain fabric. The bottom beam is steel galvanized, with a thickness of 1.2 mm and no joints; Reel: welded steel pipe with specification of 165 and thickness of 2.0mm. Rust removal and corrosion prevention are required on the outside of the pipe wall;
Guide rail: the thickness of steel galvanized plate is 1.2mm, and it is made of split composite. The sliding surface of the guide rail shall be smooth and straight, and the straightness shall not exceed 1.5mm per meter, and the straightness of the whole length shall not exceed 0.12%. The top of the guide rail shall be arc-shaped, and its length shall be at least 75mm longer than the opening. The guide rail with smoke prevention performance shall be equipped with smoke prevention device, and the materials used shall be non combustible materials. The smoke isolation device and the roller shutter surface shall be uniformly and closely bonded, and the bonding surface shall not be less than 80%; The clearance between the base plate of the special fire-proof rolling shutter door and the ground should not be greater than 20mm.
2、 Control system function: the roller shutter can be independently controlled and has manual function. It is linked with the temperature fuse device and directly linked with the central fire control room; To realize smoke alarm, the roller shutter will automatically drop to the height of 1.5-1.8m on the ground, with a delay of 180 seconds (adjustable), and then it will be closed after falling. When falling, it can stop falling and rise when encountering obstacles;
It can realize the first sliding of the smoke alarm and the second sliding of the temperature alarm. After the temperature alarm is eliminated, the second sliding can be stopped and can be converted in one system. Comply with the requirements of standard 6.4.6; Vertical opening and closing speed: not less than 2m / min. The self weight falling speed shall not be greater than 9.5m/s and the average noise shall be 85dB.
3、 Motor function: 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 fire shutter door shall be equipped with manual opening and closing device for use in case of power failure;
It shall have the capability of falling by the self weight of the roller shutter and constant speed. The operating force of the manual quick release device shall not be greater than 50N; Fire fighting power supply shall be used for the fire-proof rolling shutter door. The power cord shall be concealed through the metal pipe, and fire protection measures shall be taken for the exposed laying; When there is no fire alarm, the roller shutter has the basic manual and electric functions of up, down and down, and the upper and lower limits are accurate and reliable.
In addition, when we check the process, we strictly prevent the electric roller shutter door from hitting the top or bottom or reversing. In case of emergency, we should immediately stop rotating, cut off the power supply, pay attention to safety, and come to our website for more relevant information http://www.jnzxmy.com Consult and understand.
