Composition and Working Principle of Pvc High-Speed Door

The PVC fast door has been a popular industrial door product in recent years. Its main function is to quickly isolate and ensure the dust-free grade of workshop air quality. It is widely used in food, chemistry, textile, electronics, supermarkets, refrigeration, logistics, storage, and other places. Customers who install it know that it can prevent wind, dust, and insects.

In fact, the other function of the PVC high-speed door is ignored by everyone, and that is energy saving. Each quick switch can reduce the loss of internal temperature in the workshop, thus achieving the effect of energy saving for enterprises. Quickly open and close to isolate air, effectively avoid air loss, keep the internal temperature stable, isolate the troubles caused by the external temperature differences, and greatly save power consumption of air conditioning and other products.

To provide an excellent working environment for enterprises, more and more enterprises choose to use PVC high-speed doors to improve the production efficiency of enterprise users.

Composition of PVC high-speed doors

The PVC high-speed door is composed of a door frame system, door curtain system, drive motor, and control system.

Frame system: mainly made of carbon steel plate or aluminum alloy.

Door curtain system: mainly composed of PVC woven fabric or aluminum alloy profiles.

Control system: Most of the control systems used by domestic door enterprises are based on PLC/frequency converter/encoder

Safety system: mainly infrared eye switch, safety air pressure sensor, or light curtain system. The light curtain system should be the highest level of security protection. Lifting speed: 0.8m/s-1.5m/s, generally about 2 seconds from bottom to top.

There are many ways to trigger the door opening signal, such as a manual button, radar sensing, infrared photoelectric sensing, remote control, etc.

Working principle for PVC high-speed doors

The working principle of PVC high-speed door: the drum is supported by the bearing blocks on the guide rails on both sides, the PVC high-speed door curtain is rolled on the drum, and the door opener is installed on the shaft end of the drum. When the control box is in the manual position, press the open and close buttons manually, and the door curtain rolls up or down to realize the opening and closing of the door curtain. In place, the limit switch and servo control count limit to ensure that the error of 300000 times is less than 1mm;

When the control system is in the automatic state, the radar controls the opening and closing of the door. When the PVC high-speed door will reverse and return to the fully open state. For example, the quick-roll door equipped with the infrared photoelectric switch will also return to the fully open state when the infrared curtain is blocked by the figure. In addition, geomagnetic sensors can be installed according to user requirements. The faster it rises, the better it is. When it comes to the right position (about 20cm), there needs to be a deceleration buffer stop process to prevent collisions with the track, prevent people from getting caught, and reduce noise. This is also a standard to measure the performance of PVC high-speed doors.
