Precautions for the installation and use of Pvc high speed doors

The structure of pvc fast door :

The pvc fast door is composed of the door body frame  +  door curtain with aluminum alloy wind-resistant rod + door curtain reel transmission system + power output (electromagnetic brake motor) + pvc fast door limit device (referring to travel  or  positioning rotary encoder) ) +  pvc fast door control brain ( intelligent control box for pvc fast door ), which consists of the above five parts, and external trigger signal sensing devices (such as manual buttons, radar, geomagnetic ring sensors, access control, remote control, pull rope, photoelectric, etc. ) combined. With fully automatic door opening and closing performance.

PVC fast door frame: door chassis + door chassis panel + pvc fast door guide rail (door leg)

 The door frame is currently divided into two types: metal door frame and stainless steel door frame

A : pvc fast door metal door frame:

The high-quality anti-corrosion metal steel plate produced by Wuhan Iron and Steel Co., Ltd. is selected. The door frame is made of 2.0mm cold - rolled steel plate of Wuhan Iron and Steel Company .

B : Stainless steel door frame:

According to customer requirements, 3042B type or  202 stainless steel plate can be selected for bending and forming. Thickness: 2mm  , stainless steel mirror panel or brushed stainless steel plate is optional for the appearance (the surface is processed by drawing treatment technology).

 pvc fast door product features:

PVC fast door , as the  name suggests, is a  rolling shutter door that can be rolled up and opened quickly (high speed) . 

Advanced intelligent control technology relies on advanced high-quality hardware and software. The pvc fast door control box adopts a high-performance upgraded control box with high control precision; high-torque inverter, while using frequency conversion chip integrated circuit control technology, has soft start, The slow stop function ensures the smooth rotation of the door body and increases the service life, and has the function of power-off protection. The pvc fast door program is programmed with complete common control function data, and is equipped with a variety of ports for connecting external trigger signal sensors. Easy to use and operate. (such as manual button, radar, geomagnetic ring sensor, access control, remote control, pull rope, photoelectric, etc.)

The rapid opening of the rolling shutter door greatly improves the waiting time for people or vehicles (such as forklifts, trucks, and working equipment) to enter and exit the door. The high-speed opening and closing of the pvc fast door can also control the dust-free environment in workshops and special areas. Extremely applicable. Can effectively prevent the inflow of dust, insects and dirty air.

Advanced opening and closing buffer design of pvc fast door :

Safe and fast doors - from professional quality design! When the door body is opened and closed, the door body runs to about 20CM from the upper and lower limits to perform a deceleration and buffering action. This function can make the door body stop smoothly, and at the same time minimize the wear of various transmission components, especially the electromagnetic brake. The brake pads of the motor effectively prolong the service life and enable more accurate parking positioning. Humanized - adjustable closing delay function (adjustable from 0-9999 seconds), adjustable ascending / descending acceleration function, adjustable ascending / descending buffer function, all of which can be independently debugged. Make the pvc fast door run smoothly during opening and closing, low noise, reliable performance, and the life of the components ensures the longest use.

There are various ways to control the opening of the door:

Customers should determine the opening control of the pvc fast door according to the site and their actual needs . It is not that the more functions, the better, so as not to spend more money, and the functions are not practical or not available, resulting in unnecessary waste.

Opening speed of pvc fast door : 0.6 m / s --- 1.5 m / s adjustable. Golden ratio transmission ratio configuration: let the frequency converter play the best advantage. The diameter of the reel is 140mm (good bearing capacity ), the reduction ratio of the reel reducer is 1:15 , the speed of the pvc fast door motor is 1380-1400 rpm / 0.75-2.2kw The diameter of the reel of  the fast rolling door, the reduction ratio of the reducer, And the ratio of motor revolutions needs to undergo strict tests from slow to high speed operation. The configuration can fully meet the physical properties of the product design, high-speed rotation tolerance, limit, and practicality. The product will be noisy, some parts will be easily damaged, and the overall life of the door will be shortened.
