What are the maintenance of roller gates?

The maintenance of the roller gate is very important. Like the car, it needs maintenance and maintenance. The maintenance and maintenance of the three roller gate directly affects the service life of the three roller gate. Therefore, regular maintenance and maintenance of the three-roller gate must be done regularly, and it must be done as required. Many users rarely maintain or even have no maintenance at all. When the machine is broken, they think of the manufacturer and then replace the parts. This is often due to small loss, usually no maintenance at all, a little bit of a problem, a long time will cause a lot of trouble, so the majority of new and old customers must know the importance of the maintenance of the three roller gate. General maintenance pay attention to the following points:

First, external maintenance

Most of the three roller gates are made of domestic SU304 stainless steel. Once a week, the exterior surface is cleaned, the rust spots are removed, the outer surface of the chassis is polished with a soft cloth and fossil powder, and the anti-rust oil is applied. Rub, wait 3-5 hours to dry naturally to touch, otherwise it will destroy the surface rust-proof effect. If it is painted on the outside, wipe off the dust on the outside, expose it to scratch, use the same color paint to make up, or use the 'Li Duobei' used in the car to repair it.

Second, the movement maintenance

The movement is the heart of the machine and must be well maintained. Generally, it is maintained once a month. Open the upper cover to cut off the power, clean the dust, and clean the transmission part first with butter or high concentration oil. Check the fasteners for looseness, tighten the fasteners, check the wear of the wearing parts, the positioning arm and the positioning plate have more than 3mm, the above clearance is replaced in time, the normal clearance (1-1.5mm), solenoid valve Appropriately add butter or oil in the core, so that the solenoid valve moves in the left and right to reduce the resistance, get lubrication, not add too much, to be moderate.

Third, the circuit part of the maintenance, according to the previous use, see if there is a problem in the electronic control part, no problem, then check whether the power supply is exposed to bandage, wire to sort, wire is aging, replace it, refer to the three roller gate manual, Check the parameters of each part. If you have any problems, you should find out the root cause of the problem and replace the individual electronic components.

Fourth, the above maintenance must be maintained by a special person, especially the maintenance of the electronic control part, to be trained professionals, fully understand the principle of electronic control, in order to work.
