Remote control maintenance of Guangming trackless expansion door controller / quick replacement of caster of Zhenmei automatic expansion door base plate
quick replacement of caster of Zhenmei automatic expansion door base plateBecause of the complex structure, the failure rate of the electric door is high. Many times, the electric door will have some small problems. There are two ways to analyze and deal with this phenomenon. Sometimes, the electric door cannot respond to microcomputer operation or local operation. After checking the power supply, it was not found that the electric door had no power. It can even lead to machinery. The operators in this field must study carefully and patiently, and can only work after passing the training. In case of problems during operation, the manufacturer shall be contacted in time to observe the wear and prevent major accidents and accidents. Do well in lubrication. Poor lubrication and maintenance of the electric expansion door will also cause assembly clearance of parts. Due to assembly and other reasons, it is difficult to ensure the uniformity of fit clearance. Lubricating oil is not easy to form a uniform oil film on the friction surface to prevent wear. Thus, the lubrication efficiency is reduced and the early abnormal wear of parts is caused. In serious cases, it will cause scratches or engagement on the friction surface of precision fit, leading to failure. Check the noise level. During the operation of the electric expansion valve, the noise of the equipment increases and the quality of the equipment decreases. Therefore, check the noise, report the problem to the manufacturer in time and deal with it in time. Regularly check whether the components are loose, because the components of the electric expansion door are loose.The measurement of high-rise buildings shall be carried out when the wind force does not exceed level 4. The vertical position and column position of the electric door shall be checked regularly every day. The measurement of the electric gate grid shaft shall be coordinated with the measurement of the main structure, and the error shall be adjusted in time without accumulation. The structure of the inclined bar of the expansion door in our factory determines the integrity and straightness of the expansion door. The more the diagonal bar passes through the main straight bar, the better its integrity and straightness (it can also be judged according to the number of squares formed by diagonal bars between the main straight bars of each span, which is better). In order to save materials, some manufacturers have added upper and lower blanks to make the door lose some functions. The telescopic door is driven by the part of the head to drive the whole door. Therefore, the weight and strength of the head plate are particularly important. At present, there are three types of cement substrate, thin iron plate and cast iron substrate on the market. Whether the cement base plate has weight or strength, whether the thin iron plate has strength or not, and whether the ultra thick cast iron base plate has weight and strength. The head base plate is made of super thick cast iron. For the longer expansion door, the counterweight will be increased proportionally to make the operation of the expansion door more stable. Automatic expansion doors are generally made of stainless steel and aluminum alloy.At present, the trackless expansion door has been widely used in enterprises, factories and other units. The utility model has the advantages of no need to install the track on the ground, increased the aesthetics, more convenient vehicle access, and reduced the damage of the track and the impact of the vehicle. Automatic expansion doors are widely used in large shopping malls, enterprise gates, building communities, even schools and other occasions. The appearance is beautiful and atmospheric, which greatly improves the image of the application unit. Although the automatic expansion door is solid, how to extend its service life? Correct use skills. The automatic expansion door must be operated in strict accordance with the instructions. During the operation of the automatic expansion door, it is necessary to avoid obstacles. In case of any obstacle during operation, the power supply shall be cut off in time. When opening the automatic expansion door, the action shall be light. If the strength control is not good, the electric door will be damaged.
