Importance of elevator maintenance

A lift in the installation and put into operation, due to the installation, maintenance of the limitations of the process, the use of conditions and environmental impact, will inevitably occur in various types of failure.The most common reason is the adjustment of mechanical parts, and the design of the manufacturers to use a variety of protective functions to protect the role of.The former is related to the quality of products, installation and maintenance. In general, the mechanical strength of the mechanical parts is insufficient, the design defects and the displacement result in the displacement. The latter is relatively complex, the operation of the elevator is a complex process, must have the conditions set, starting to lift, under certain conditions, it can run continuously, meet certain conditions, to the normal speed and parking.Therefore, if the elevator is forced to meet the conditions in which it does not have the conditions (such as the cancellation of a detection function or short circuit), there may be some danger.Light will cause further damage to the equipment, causing heavy casualties and other serious accidents.Obviously, how to carry on the correct, timely and thorough maintenance to the elevator equipment is very important.

Elevator maintenance is mainly based on mechanical adjustment, through constant correction of the installation of the nominal size of the parts required to make it in the specified range of normal operation, has reached the standard parts to be scrapped in a timely manner to be replaced;At the same time the necessary cleaning, moving parts and structural parts lubrication and anti rust and to safety, prolong the service life of equipment maintenance purpose.For electrical parts, maintenance work needs to maintain its good insulation, to ensure adequate supply of power to the equipment to run.

Elevator maintenance is a comprehensive strong work, should not only include the adjustment and maintenance work not done, according to the fault characteristics and causes of the elevator, combined with the actual situation, the necessity of improving the structure and performance of the elevator.

A qualified elevator maintenance, in addition to the working principle of the elevator to fully understand, but also must have good mechanical capability (fitter, welder), a considerable understanding of the principle of electrical, electronic technology need to know and be able to use some of the basic functions.At present, it is more required to master the principles of programmable control, digital circuits, microelectronics technology and application, but also to understand the deeper understanding of the principle and application of scm.So, in the full understanding of the elevator fault situation, according to the working principle of the elevator, the elevator according to his knowledge, work flow, analyze the causes of failure and failure scope may exist, in accordance with the vision inspection steps and observed presence of failure state, gradually remove the suspected failure problem, in order to correct to determine the fault point, thorough maintenance.
