The types of high speed doors of SHENZHEN HONGFA AUTOMATIC DOOR CO., LTD. are as follows: 1. High speed roller door. The high speed roller door is the most used and relatively economical high speed door in the market. The main materials of the high speed roller door are PVC and stainless steel. PVC is used for the door curtain, and stainless steel is used for the door frame. The thickness and color of the door curtain can be selected, and the material of the door frame can also be selected Stainless steel or aluminum alloy. 2. Auto recovery high speed door. Also named zipper high speed door. The auto recovery high speed door is also a kind of PVC high speed door. The difference between it and the high speed roller door is the door curtain and the connection between the door curtain and the door frame. The curtain of the high speed roller door uses a windproof rod, and the auto recovery high speed door does not have a windproof rod, and the connection with the door frame is sealed with a zipper, so the sealing of the auto recovery high speed door is better, and after the door curtain is accidentally knocked off by human operation Self-healing is possible. 3. Cold storage high speed door. The cold storage high speed door is a kind of zipper high speed door. The main difference between it and the ordinary zipper high speed door is the door curtain. The cold storage high speed door uses a special environmental protection door curtain for low temperature. Cold storage saves a lot of energy, and the power saving rate reaches 35-80%. Cold storage zipper high speed doors are a major trend of cold storage doors in the future. 4. High speed stacking door. The high speed stacking door is similar to the high speed roller door. It also has a windproof rod, and has more straps than the high speed roller door, so it is also called a strap door. The size of the high speed stacking door can be much larger than that of the high speed roller door. It has stronger wind resistance than high speed roller doors and is suitable for outdoor installation. 5. Turbine hard high speed door. Turbine hard high speed door is a kind of aluminum high speed door. Its door panel is made of aluminum alloy. The total thickness of the door panel reaches 40MM. It has the characteristics of good heat preservation, light weight, high strength, impact resistance, etc. Class 12 and anti-theft, suitable for fast lanes for indoor and outdoor logistics and production, parking lots, home villa garages, fire industry, 4S stores, etc. 6. Simple hard high speed door. The simple hard high speed door is an economical aluminum high speed door. The main difference between it and the turbine hard high speed door is the door head. The door head of the turbine hard high speed door has a turbine, while the simple hard door does not have a turbine. The simple hard high speed door is more sophisticated in production, takes up less space, and is suitable for openings with small space and small temperature difference between the inside and outside of the door. The price of the simple hard high speed door will be much cheaper than that of the turbine hard high speed door.

Industrial fast rolling shutter door product introduction The functional characteristics of industrial fast rolling shutter door are loved by the majority of users and widely used. Industrial fast rolling shutter door is a fast lifting barrier isolation door. The opening speed of Hongfa fast rolling shutter door can reach 0.8-2 meters/second, and the opening and closing speed is dozens of times that of ordinary electric rolling shutter door. The main functions of Hongfa fast rolling shutter door are heat preservation, moisture, dust prevention, insect control, anti-static, sound insulation, etc., which can keep the workshop constant temperature, constant humidity and clean. Industrial fast rolling shutter door is suitable for food, medicine, electronics, rubber, chemical industry, automobile, textile, logistics, machinery and other fields. Rapid industrial book door is essential tool for enterprise environmental protection and energy saving, and fast shutter has been popular for many years in the developed industrial countries, enterprise's workshop and channel between a fast shutter door installation, for food and medicine, and other enterprises, according to government requirements, mandatory use fast shutter isolation, in order to prevent the products from secondary pollution. In recent years, many enterprises have the consciousness of installing Hongfa fast rolling shutter door, which is of great help to ensure product quality and reduce energy consumption. Second, fast rolling shutter doors can also improve the overall image of the company. With the continuous improvement of the national requirements for production environment, Hofic high speed door will become a necessary equipment for production enterprises. 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.
