The maintenance of the three-roll gate is very important. Like the automobile, it needs maintenance and maintenance. The maintenance and service of the three-roll gate directly affects the service life of the three-roll gate. Therefore, regular maintenance and maintenance of the three-roll gate must be done regularly, and it should be done as required. Many users rarely maintain or even do not maintain it at all. Only when the machine is broken, does it think of the manufacturer and only then replace the components. This is often due to small losses, usually there is no maintenance, a little bit of a problem, a long time will affect the use, so the user must be aware of the importance of maintenance of the three roller gate in use. The three roller gates generally maintain the following points:

First, external maintenance
Most of the three-roll gates are made of domestically produced SU304 stainless steel. Once a week, the exterior is cleaned, rust spots are removed, the surface of the chassis is polished with a soft cloth and fossil powder, and anti-rust oil is applied. The rust-proof oil just applied is not to be used by hand. Rub, wait 3-5 hours natural drying can hand contact, otherwise it will destroy the surface rust effect. If it is sprayed on the exterior, wipe out the dust on the outside and expose the scratches. Use the same color paint to make up for it, or use the "Lidobe" used in the car for repair.
Second, the movement maintenance
The movement is the heart of the machine and it must be maintained. It is generally maintained once a month. Open the top cover to cut off the power supply, clean the dust, and then clean the drive section and add butter or high-consistency oil. Check whether the fasteners are loose, tighten the fasteners, check the wear of the wearing parts, position the arm and the positioning plate more than 3mm, replace the above gaps in time, normal clearance (1-1.5mm), solenoid valve The proper addition of butter or oil in the core, so that the solenoid valve in the left and right movement is to reduce the resistance, get the lubrication, not too much, should be appropriate.
Third, the circuit part of the maintenance
According to the previous use situation, to see whether there is a problem in the electronic control part, if there is no problem, check whether the power supply is exposed to be bandaged, the wires are sorted out, and if the wire is aged, replace it. Refer to the instructions of the three-roll gate and check the parameters of each part. If you have problems, you must follow it, find the source of the problem, and replace individual electronic components.
The above maintenance must have special personnel to maintain, especially the maintenance of the electronic control part, to be trained professionals, a full understanding of the principle of electronic control, in order to post operation.
