Professional replacement of Longgang automatic expansion door sign = installation and replacement of Longhua electric expansion door trackWhen we install the electric door, there are usually many ways to install the bottom pulley for us to choose from. One of the inlaid slideways is a common one. What are the advantages of this installation method for the use of electric doors.With more and more large-scale parking lots need more and more public places, the demand for automatic expansion doors in Longgang District is increasing, but there are also higher requirements for performance and technology expansion doors, which means that the development of expansion facing doors is no longer pure, more is the pursuit of high-tech development direction, but also shoulders a new development mission!Inlaid guide rail for electric door row, including door row, slide block and hinge rod. One side of the door row forms a slide way, which is characterized in that the slide way of the door row is embedded with a lining body, the two ends of the lining body are fixed in the slide way, and the middle part of the lining body is embedded in the slide way. The reason for adopting this structure is that the structure can isolate the operation of the inner wall of the sliding groove between the surface contact and the slide block in the electric door, so as to avoid the direct friction between the slide blocks caused by the noise and the damage of the sliding groove and the surface coating to the slide groove line of the door. In order to further explain the above purpose, structural features and inlay guide rail of the electric door row, the inlay guide rail of the row is described in detail below. The force direction of the electronic door does not affect the opening action of the doorHaifeng part of the electric door used for a long time, in the later use process often failure. Why? Solve the problemWhat are the methods of failure in daily use?1. Insert the clutch key into the clutch of the power door. The clutch is located in a concave hexagon groove at the end of the shaft, and the chain is tied at the end of the motor. Then rotate 180 degrees clockwise. At this time, press the remote control control switch once to check whether the motor is no longer idling and connected with the chain.Haifeng electric door can move, but it will stop intermittently again and again, and the motor rotates very slowly.This may be due to voltage instability and low voltage. First, check whether the voltage is stable step by step. When this phenomenon occurs, check the voltage. If it is confirmed that the voltage is within the normal range, and there is still a phenomenon of non permanent use, it can be preliminarily concluded that there is a problem in the motor or control system. The way to detect whether the controller has faults is to directly press the switch stop key with the remote control, and observe whether the prompt light on the control board is on or off. If it is on, the controller is OK. The next step is to connect the motor directly to the 220 V power supply. If there is rotation, it means the motor is normal. According to this method, check and check respectively, and analyze whether the fault is motor or controller. If the above method is still invalid, it means that the service life of the motor or control system has aged naturally and needs to be replaced.
