The maintenance of the three-roller gate is very important. Like automobiles, it requires maintenance and maintenance. The maintenance and maintenance of the three-roller gate directly affect the service life of the three-roller gate. Therefore, the three-roller gate must be regularly and regularly maintained and maintained, and must be done according to the requirements. Many users have little or no maintenance at all. When the machine is broken, they only think of the manufacturer and then replace the parts. This is often caused by a small loss, and there is no maintenance at all. A little problem will cause a lot of trouble after a long time, so the new and old customers must understand the importance of the maintenance of the three roller gate. Note the following points for general maintenance:
1. External maintenance
Most three-roller gates are made of domestically made SU304 stainless steel. The exterior is cleaned once a week to remove rust spots. Use a soft cloth and fossil powder to polish the exterior of the chassis. Apply anti-rust oil. Do not use the anti-rust oil just applied. Wipe, wait for 3-5 hours to dry naturally before touching it, otherwise it will destroy the surface anti-rust effect. If it is sprayed on the surface, wipe off the dust on the surface, and have scratches on the surface, use the same color paint to repair it, or use the car's 'Lidobe' to repair it.
Second, 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 and cut off the power, clean the dust, and then clean the transmission part before adding butter or high-concentration motor oil. Check whether the fasteners are loose, tighten the fasteners, check the wear of the wearing parts, the positioning arm and the positioning disk have more than 3mm, the above clearance should be replaced in time, normal clearance (1-1.5mm), solenoid valve Properly add butter or engine oil in the core to make the solenoid valve move left and right to reduce resistance and get lubricated. Don't add too much, it should be moderate.
3. Maintenance of the circuit part . According to the previous usage, see if there is any problem in the electric control part. If there is no problem, check whether the power supply is exposed and bandaged, the wire is sorted, and the wire is aging. Replace it. Refer to the manual of the three-roller gate. Check the parameters of each part. If there is a problem, it is necessary to find out the root cause of the problem and replace individual electronic components.
Fourth, the above maintenance must be maintained by a dedicated person, especially the maintenance of the electronic control part. Only trained professionals must fully understand the principles of electronic control before they can start operation.
