How to position the rapid door?
Fast rolling door, high-speed door, high-speed rolling door is a kind of industrial door that controls (PVC material) curtains to quickly lift and accurately position through PLC, frequency converter, and encoder. It is mostly used in food, electronics, printing, etc. that have strict environmental requirements. In high places, its main function is to quickly isolate and ensure the dust-free air quality of the workshop. Positioning method of rapid door: The high-speed door is a barrier-free isolation door that can be raised and lowered quickly. Its main functions are thermal insulation, moisture protection, dustproof, insect-proof, sound insulation, etc., so that the workshop can maintain a constant temperature, constant humidity, and clean working environment. Suitable for food, medicine, electronics, rubber, chemical industry, automobile, textile, logistics and other fields. There are two methods of positioning fast doors: Mechanical positioning: This positioning method is similar to that of steel rolling shutters. The advantage is that it is fast and has low requirements on the controller. Rotary encoder positioning: The elevators we often ride in are all positioned using rotary encoders. The advantage of this method is accurate positioning. Taking an encoder with a resolution of 1024 as an example, a 3-meter-high door is divided into nearly 9,000 points. , in theory, the height can reach 0.3mm, and the height setting is simple. During the operation and use of the rapid door maintenance, the operator is not allowed to leave the operating location without authorization, and should pay close attention to the opening and closing conditions and execution. No one is allowed to stand or move under the rolling shutter during opening and closing. To prevent the travel switch from malfunctioning, the roller blind getting stuck, the motor being blocked and other accidents. The steel rapid doors for partitions and partitions are usually not used frequently. Once a fire breaks out in the area, the rolling shutter door should be effectively put into use. Maintenance of automatic control fast doors with linkage control and control center control must be carried out according to a set of control instruction procedures.
