What are the skills to master when using large industrial lifting doors
The motor used in the industrial lifting door belongs to the short-time working system, and its connection working time should not exceed 10 minutes. If the operating time is too long, it is easy to cause the thermal protection of the motor to take effect. Therefore , the daily operation of the industrial lifting door should not be continuous, long-term Time to carry out, operate when necessary, stop immediately when not necessary. The control boxes of industrial factory doors are generally installed on both sides of the door body, and their positions should be kept at a certain height during installation to prevent children from touching them accidentally. Operate the remote control The remote control that is turned on and off on a daily basis must be kept by a special person and must not be thrown away at will to prevent children from touching it and causing accidents.
For industrial lifting doors, we must check its surface before use to ensure that it is intact, and when installing, we must install the installed balance springs to ensure its balance. If it is not very good, it may cause it to be damaged more quickly when it is turned on and off. We must also ask those specialized personnel to install it when installing, and when installing the wiring The situation should also be selected according to the building at the construction site. When installing a biscuit, it must be installed with the door closed, and we need to prevent people and vehicles from passing underneath when the product is running, because it is very unsafe.

What are the advantages and functions of Pvc fast doors
The pvc fast door is a pvc fast door that is different from ordinary electric fast rolling doors . It is relatively close in terms of functional application, and can also achieve wind resistance, insect resistance, glare resistance, and sound insulation. So, which places are the flexible pvc fast doors suitable for, but it is more suitable for places with large door openings and harsh outdoor environments.
First of all, the opening method of the flexible Pvc Fast Door is different from that of ordinary fast doors. The pvc fast door is lifted and lowered by the rolling curtain of the door shaft, while the door body of the flexible pvc fast door is a stacked stacking strap that rolls to open and close. Since the stacking door is often used in an outdoor environment with a very large door opening, the door body is large in size and has its own load. The load is also large, and the aluminum alloy wind-resistant ribs on the cord are superimposed on the weight, so it is easier to design stacked up and down. The disadvantage is that the lifting speed is slightly slower than ordinary PVC fast doors. After all, the weight of the door body is not the same as that of ordinary fast rolling doors. Due to the heavy weight of the flexible PVC fast door itself, the wind resistance is better than ordinary fast rolling doors. In terms of sealing performance, the bottom of the roller blind has an air-tight design of elastic PVC polyvinyl cloth, which can fit perfectly with uneven ground to achieve a good sealing effect.
What is the purpose of installing the safety contact bottom edge on the pvc fast door? In fact, the safety contact bottom edge is a safety protection device for the pvc fast door. It is installed at the bottom of the door leaf. When the door leaf is falling, the bottom of the door leaf contacts with obstacles When the air bag is in contact with the bottom edge, the air bag is compressed to form an air pressure start signal switch, and the control system controls the door leaf to stop immediately or run upwards, thereby protecting the safety of pedestrians or vehicles.
The bottom edge of the wireless safety contact is mainly used for industrial lifting doors. The bottom edge of the wireless safety contact is installed at the bottom of the lifting door body, with a built-in airbag-gas sensitive relay, and the wireless transmitter is set next to it to connect with the airbag-gas sensitive relay. The wireless transmitter It is wirelessly connected with the wireless receiver inside the control box, and it uses remote control to send command signals to the control system, thereby completing the protection and control of the door body, and completely solving the safety hazards of the helix. It has the characteristics of convenient installation, strong anti-interference ability, high sensitivity, accurate control, safety and reliability.
The bottom edge of the wired safety contact is mainly used on the pvc fast door. First, connect the airbag box connection line to the PLC terminal GND terminal of the control box. If there is no GND terminal connection, you should pay attention to connecting the COM line to the G point. Wrong, when the pvc fast door touches the airbag of the pressure tube when it falls to the ground, it cannot receive the signal. A function test is required after installation.
The safety contact bottom edge function test process is as follows: first turn on the power of the control box, turn off the emergency stop switch, press the learning button on the control panel of the airbag receiver once, the signal receiver light is on, and then press the airbag pressure hose several times, the signal receiver light flashes and the memory is successful, repeat Press the pressure hose of the airbag, press once and the light of the receiver lights up once, indicating that the signal connection is successful. Then turn on the emergency stop switch and press the cloth pocket pressure hose door to automatically rise and the test is successful.
Troubleshooting of safety contact bottom edge: If the control box cannot receive the airbag signal during testing and use, check the battery in the transmitter to see if the battery is exhausted and needs to be replaced, and check whether the pressure hose is damaged or leaking. Repair or replace if damaged.
