    How to maintain the elevator

    With the advancement of science and technology, the level of design, manufacturing, installation, inspection, repair, maintenance, and use of passenger elevator technology and management has been continuously improved, and the reliability of its operation has increased significantly. But in the maintenance, there are still some typical elevator stop failures, among which the failure of the safety circuit causes the elevator to fail the most. 1. The elevator stops due to phase failure When the three-phase power supply is out of phase, the phase sequence relay will act to cut off the safety circuit and stop the elevator. This kind of failure is mostly caused by elevators controlled by relay logic. Because it is an old-fashioned elevator, the power switch is mostly knife-type, and the current of the elevator running and starting is very large. After a period of operation, if the maintenance personnel do not check in time, the fuse and the screw connection are easily blown, and the elevator loses the phase, causing the elevator to stop, ranging from shutting down the person to the accident. Maintenance personnel should conduct frequent inspections, find suspicious points, and repair them in time. If there are hot and sparks, they should be replaced immediately. It is recommended that the user replace the knife switch with an air switch of equivalent capacity. The elevators currently designed do not have power limit switches, and the safety circuit can be slightly modified, that is, add upper and lower limit electrical switches in series in the safety circuit, and remove the original limit switches. 2. Such failures require maintenance personnel to frequently check the door lock contacts, gaps, whether the hall door wire rope is stretched, whether the door connecting rod is loose, and whether the door lock block hook is deformed or damaged. Find problems and eliminate them in time to reduce unnecessary elevator shutdown failures. In reality, the elevator stops running and people are locked in the car from time to time. As the elevator was shut down, the people in the car panicked, kicked and clashed randomly, causing damage to the elevator or personal injury or death. Therefore, reducing Passenger Elevator Factory stop failures is a very important issue for manufacturers.
  2. As an indispensable means of transportation for ordinary people, in addition to safety, reliability and comfort, elevator supplier have attracted the attention of the public. Intelligence and even technology and fashion are becoming a quiet trend, whether in our villa elevators or commercial passengers. elevator. If you want to choose a villa elevator, it depends on whether the hoistway is reserved. The hoistway is easy to handle, the size of the hoistway, whether the pit has been dug, whether there is a reserved machine room, the passenger elevator is divided into two types: machine room and machine-less room. , And civil engineering, etc., to design your villa elevator, the factory will give you the elevator drawings, and the construction will also follow the elevator drawings. Elevators are special equipment. The country has a series of standards for elevators, and relevant departments of the country must check and accept elevators. To test your elevator, firstly, whether the product design is qualified, and secondly, whether various indicators meet the national standards. After passing the inspection and acceptance by the state agencies, a quality report will be issued, and then a safety acceptance certificate will be issued to the owner before freight elevator can be used.
