Fast Rolling shutter door
Let's talk about the structure of the fast rolling shutter door. Hongfa fast rolling shutter door adopts cold splicing process, which reduces the heat and deformation of the curtain, and the surface looks more smooth.
First, let's talk about the frequency conversion control system of fast rolling shutter door. Each fast rolling shutter door adopts high-quality frequency converter, which can improve the overall performance of fast rolling shutter door. PVC fast rolling shutter door is a new type of fast door with high speed partition function introduced by Hongfa Company according to the market demand. The whole outer frame adopts cold rolled steel plate electrostatic spraying treatment, beautiful and generous. The control system adopts asynchronous motor and frequency conversion device, and is equipped with bright blue screen LCD display as the man-machine dialogue window. It has the characteristics of standardization, strong operability and low maintenance cost. It can guarantee the annual operation of more than 300,000 times, daily operation of more than 1000-1500 times, and provide comprehensive warranty service within one year after installation.
Take a look at the characteristics of the fast rolling shutter door. The overall outer frame of the fast rolling shutter door is made of electrostatic sprayed cold rolled steel plate and all aluminum alloy outer frame, which is beautiful and generous (customized).
The control system adopts standard asynchronous motor and frequency conversion device, which is easy to operate and low maintenance cost. It runs fault-free 300,000 times a year and 1000-1500 times a day. The fast shutter door control system is an independent microcomputer controller with modular plug and play design to reduce the maintenance cost. There is also frequency conversion end buffer function for motor abnormal response time of 0.3 seconds, emergency protection motor. The driving motor is a professional high frequency start and stop motor, high efficiency, strong braking torque, long service life. Fast rolling shutter door limit mode is non-contact pointer limit, no cumulative error, can prevent magnetic field interference. The power supply must be 220V, 13A, single-phase, or 50HZ.
And the next is to introduce the extremely important motor of industrial fast rolling shutter door. The specification range of fast rolling shutter door is W=1200mm-5000mm,H=1500mm-5000mm. Curtain material adopts PVC thickness of 0 wear resistant base cloth, 8-1.2mm, high wear resistance, composed of high strength polyvinyl chloride coated polyester mesh belt and streamlined glass fiber reinforcement.
Flame retardant grade up to Class2. And wind resistance ability Z can resist 6 wind, strengthen up to 8 wind.
All fast shutter doors are called fast, the main reason is that the opening and closing speed is fast, and the opening and closing speed of fast shutter doors can reach 0.8-2m/s, and the switching frequency can exceed 500 times a day, more than 150,000 times a year.
At ordinary times, it can be used in the working environment temperature of 40℃-80℃. The sealing performance is that the track adopts the double row brush sealing structure, which is more effective in insect and dust prevention. Safety features are also configured with infrared safety protection electric eye, and power failure or emergency measures, you can use ordinary plate hand to open the door. Control box is Hongfa automatic door IP54 control box, waterproof and dustproof, harsh environment can be used normally. The switching mode is generally standard double-sided button, but also optional radar induction/geomagnetic ring induction/rope switch/Remote Control switch. The reserved port is a commonly used signal interface in induction, such as induction door opening, double door interlocking, remote control, etc.
