Make pvc fast door

Just like the car factory configures the car's engine + gearbox + wheel diameter, the ratio is very important. If the diameter of the tire is increased, it may save fuel when driving at high speed, but when the car is running at a low speed or encounters a slope, the power output of the engine is obviously insufficient, which seriously damages the engine. The pvc fast door motor is like an engine, and unreasonable configuration will shorten the life of the motor. If the diameter of the reel becomes smaller, the lifting speed of the pvc fast door will decrease. If the reduction ratio of the worm gear reducer is increased, a motor with a larger power should be added.

pvc fast door fully open time:

If the ascending acceleration speed is set to the highest through the frequency converter, the diameter of the reel is 140mm , the reduction ratio of the reel reducer is 1:15 , and the speed of the pvc fast door motor is 1400 rpm . Then its theoretical door opening time is about three seconds to open (the height refers to the door of 4.5 meters), if the deceleration buffer time of the door curtain before running to the upper limit and the lower limit is added, the fastest and accurate time for the door to fully open is about for four seconds.

Precautions:

The correct use method and proper maintenance will help to prolong the service life of the pvc fast door (once the product is installed, our technical staff will set the most reasonable lifting speed depending on the size of the door body, and generally do not need to be adjusted by the customer, please tampering with affairs). The customer should set the opening and closing speed of the PVC fast door according to the actual needs , otherwise it will cause unnecessary waste of energy and friction loss of transmission parts. As long as the passing requirements are met, try to lower the speed of the PVC fast door , especially for larger doors. Helps protect the frequency converter for a longer lifespan.
