All types of access gates are organically integrated with mechanical, electronic, microprocessor control, and various reading and writing technologies. In recent years, they have become more and more popular. People can often see them in subways, railway stations, scenic spots, and halls. Various gates. First of all, we must know that the maintenance of the tunnel gate is of utmost importance. Like the automobile, it needs maintenance and maintenance. The maintenance and service of the gate affects the service life of the gate directly. Therefore, regular maintenance of the gate must be performed. To do, but also to do a good job, many users rarely maintain or even do not maintain, and other manufacturers only after the bad machine to replace 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 we must understand the importance of maintenance of the gate. Maintenance begins with the following aspects.
First, external cleaning and maintenance
The general gates are made of domestically produced 304 stainless steel, and it is recommended to clean the exterior once a week.
1, the surface is clean: Use a soft cloth to clean the surface of the dust, with a soft cloth and talcum powder to polish the outside of the chassis, conditions can be coated with anti-rust oil, just coated with anti-rust oil do not wipe by hand, etc. 3-5 About the hour, you can dry it by hand, otherwise it will destroy the effect of surface rust prevention.
2, the use of a long time, especially in outdoor use, there may be some rust spots, remove rust spots: use sandpaper and talcum powder along the long lines to wipe (protect thick grain direction), otherwise it will affect the appearance.
3, if it is the appearance of spraying or painting chassis, use a soft cloth to wipe off the dust on the outside, if exposed scratches, use the same color paint to make up, but be careful not to wing flap, swing gate of the radio eye part of the painted , otherwise the brake accident alarm, causing unnecessary trouble.
Second, movement maintenance
The movement is the heart of the machine and it must be maintained. It is recommended to maintain it once a month.
1. Cut off the power supply, open the cover of the brake, clean the dust on the surface, add the butter after cleaning the drive part first, and apply some butter to the gears and wheel slots of the wing lock and swing gate .
2. Check the fasteners and connecting rods for loosening and tighten them.
3. Check the wear of the wearing parts. The positioning arm of the tripod gate and the positioning plate have more than 3mm gaps and replace them in time. The normal clearance (1-1.5mm) is properly added in the solenoid valve core to make the solenoid valve Reducing resistance during left and right movements, and being lubricated, be careful not to add too much and be moderate.
4. Pay attention to the limit switch and the limit piece of the gate. Do not adjust it to prevent it from being too far or too close.
Third, the circuit power supply maintenance
1, cut off the power, clean the surface of dust. Be careful not to wash with water and prevent short circuits from occurring.
2, according to the previous use, to see if there is a problem in the circuit part, there is no problem, then check the circuit, power supply, wires, plug-ins are exposed or loose, to be bandaged, organize, tighten the plug, check for leakage, if the wire has Aging should be replaced.
3, refer to the gate manual, check whether the various parameters are normal, there are no aging electronic components. There are problems, we must contact the manufacturers, follow the steps, find the root cause of the problem, replace individual electronic components.
