Aluminum alloy high speed spiral door is a new type of metal industrial door which integrates the characteristics of fast, energy saving, sealing, high efficiency, wind resistance and environmental protection. It represents the highest level of industrial door in the world. Its main function is rapid isolation, so as to ensure the dust-free air quality of workshop. The door panels are manufactured in large-scale assembly line with French technology. The bridge breakage design can completely isolate the temperature loss inside and outside the room, and can effectively save energy. So what are the specific standards for hard fast doors?
The aluminium alloy hard fast door panel is made of double-layer stretched aluminium plate with PU foaming. Its surface is fine pressed stripes, which are treated by anodic oxidation and organic coloring. And the wind resistance of high speed spiral door can achieve 12 grades. Both ends of the door panel is connected by hinges, and double side seals are used between the spliced door panels. The folding life of the joint of the seals is more than one million times. The design of the broken bridge in the middle can improve the insulation effect, prevent the loss of indoor and outdoor temperature, and save energy efficiently.
Aluminum alloy high speed spiral door adopts double turbine structure, the fastest opening speed can reach 2.5m/s. Double spiral guide is advantageous to the acceleration of door body, which makes the door body more stable when sliding in the aluminum alloy track through the guide wheel made of polyurethane material at high speed.It reduces the noise and improves the safety index.
The motor drive system adopts German SEW, Siemens, servo motor and etc electronic control systems. In both gas and dust environments, it can operate reliably in these two dangerous areas.
The constant torque output of servo motor makes the switch be able to work more than 1000 times a day in some high frequency occasions. The servo electronic control box has stable performance, frequency conversion control and screen display, which is convenient for monitoring and checking.
In addition, when power failure occurs, a reserve power supply can be installed inside the electronic control system to turn on the brake of the motor at any time, and the door body can be lifted by means of the balance system, which can effectively solve the problem that the door body can not be opened due to power failure or malfunction.
Hard fast door is equipped with infrared photo sensor and wireless safety airbag. Radio eye is set on both sides of the door frame, when there are obstacles under the door, the door body keeps open; When the door body drops, the object passes through, the door body opens to the initial open position, and then delays the descent when there are no obstacles below. Sometimes, because the object is in the blind area of infrared protection, when the door body is pressed against the obstacle below, the door body rebounds quickly in the most open position, effectively protecting the object below or pedestrians to avoid accidents. At the same time, the hard fast door also has radar induction, geomagnetic induction, remote control induction, pull rope switch and other safety devices.
Aluminum alloy high speed spiral door has high reliability and practicability. It can resist strong convective wind pressure through high-speed operation. With its high working efficiency, it occupies a unique position in today's industrial field. Its unique mechanism design reduces the failure rate by 99.99%. Hard fast door can not only prevent illegal invasion by outsiders, but also resist weather changes. It is an ideal choice for industrial energy saving and energy consumption reduction.
