【 Weak current College 】 elevator equipment of periodic maintenance

We all know, elevator and other electrical equipment, the need for periodic inspection, maintenance and maintenance. Through the elevator equipment of periodic maintenance, maintenance, you can make the elevator to reach and satisfy the original design, the manufacture of standard and technical requirements; and to ensure the elevator equipment is safe and reliable operation, lower failure rates and extended life of elevator equipment. But how can we effectively elevator equipment, regular inspection, maintenance and maintenance, this is the elevator manufacturers, installation maintenance unit and elevator users very seriously and concern, following on the issue, on the personal opinions and perceptions, and us to explore, question.
1-report on work management and hardware application to establish a management system to continuously improve the hardware conditions
In the maintenance work management and hardware application, each installation maintenance unit should establish a comprehensive, systematic guarantee regular maintenance work on quality management systems and practices; and continuously improving hardware conditions, improve maintenance efficiency, quality and user satisfaction.
1.1 shall establish post responsibility system, so that the maintenance work of documenting, writing of management and user identification, supervision and management approaches.
(1) due to maintenance work is unique, it has the scalability, maintenance workload and work on-site and maintain work time is not easy to control, management features, therefore, must have the appropriate maintenance stairs of periodic checks, maintenance and maintenance work, the responsibility to relative respectively. In this way, you can increase the mobilization, on-site maintenance personnel work initiative, flexibility, and sense of responsibility; and indeed strengthen maintenance work.
(2) maintenance work and its effect is good or bad, most users have a say; let the maintenance personnel to regular maintenance work and results to the user report, and get the user's signature, and the result of feedback company (retention). In this way, both on maintenance work for effective monitoring, management, and increasing user satisfaction.
1.2 shall establish regular visits to users, collect user feedback, and maintenance of quality inspection, supervision and management of the system.
(1) should establish specialized management system, visit the user regularly send people, getting user feedback, to obtain user/site information such as first-hand information, timely feedback to the design, manufacturing and technology, installation, and other departments, for product quality and the improvement of the work; and dynamic tracing, processing the user's question or complaint, improving customer satisfaction.
(2), of course, the maintenance work of supervision, the supervision of the user alone or confirm that it is not enough (because the user is not a profession). Shall be taken by the responsible for the maintenance work and maintenance supervisor for periodic sampling, and full-time quality inspection (acceptance) of occasional special inspection combined approach to management. Ensure regular maintenance work to strictly technical specification for the maintenance, in order to work on periodic maintenance (attendance, security, maintenance of quality and service, etc.) to exercise effective supervision, control and management.
1.3 shall establish maintenance ladder users archives--i.e. maintenance stairs database management system, improve the efficiency of the management of maintenance.
(1) for every machine maintenance stairs user shall establish customer files, especially for newly put into use of Elevator, elevator and various important parts (such as door system, electrical control systems, mechanical systems, etc.), and so on, enter dimensional ladder database management system, and then sorting, statistics and analysis. In this way, you can find out the elevator failure rate is high, then the "remedy", and continuously improve product quality and installation maintenance work quality, improve the reliability of the elevator equipment, lower the elevator failure rate.
(2) establishment of user can archieves, accumulation of elevators and fault conditions, as well as the maintenance work (including replacement of parts and components), of the original data. And through these data for statistical analysis, impact, elevator and reliability factors (such as a computer crash, easy-to-wear or failed parts, etc.), ahead of pretreatment or replace wearing parts; proactive, preventive maintenance measures that can improve maintenance efficiency and user satisfaction.
(3) can the maintenance personnel in their daily work, maintenance records, and the use of user ladder, failure and replacement parts, such as daily work data (including electric/escalator inspection and acceptance of the time, cost, etc), enter dimensional ladder database management system. To strengthen maintenance personnel supervision, control and management as well as to specifically identify the user specific maintenance work elevator to formulate plans for cycle or major maintenance repair scheme, but also conducive to the management and implementation of specific management measures.
1.4 on conditions of the user (such as elevator number relatively many, centralized user or region), the use of remote control/monitoring systems, 24-hour hotline call fellow initiates, improve user satisfaction.
(1) remote monitoring/surveillance system can run on the elevator, faults and maintenance work, timely news monitoring, logging, and to effectively implement 24 h Hotline call fellow initiates, improve user satisfaction, and lay a solid material conditions and the Foundation.
(2) remote monitoring/surveillance system can also work on maintenance personnel (such as repair services of timeliness and maintenance time, and so on) for effective monitoring, management, may significantly improve maintenance efficiency, quality and maintenance work of rationalization and scientific management.
2 in technology developed specifically for periodic cycle maintenance of the technical specification for
Technically, should develop specialized for specific model elevator the regular cycle maintenance, technical rules and strict enforcement of the order is technically valid to ensure the elevator equipment periodical inspection, maintenance and maintenance of quality.
2.1 for different types of lift characteristics and user specific use cases, developing specialized regular cycle maintenance of the technical specification of necessity:
(1) Elevator equipment and other electrical equipment, the need for their use, frequency of use, take different Zhou maintenancePeriod, to the maximum guarantee of elevator equipment is safe and reliable operation, lower failure rates and extended equipment life.
(2) typically elevator maintenance cycle of periodic cycle, there are clearance, inspection, week, month and quarter and annual inspection, testing, and other six ways, in view of the characteristics of different types of lift and user specific use case scenarios, developed specifically for the maintenance of the work content or scheme is necessary. Because each maintenance system, manner, has its own focus and specific content, and links, are closely linked to each other and close contact, maintenance personnel shall be based on the existing State of the elevator and the use of frequency, the ladder of specific maintenance mode, and then carefully and strictly according to the specification and development of the maintenance plan execution, can truly guarantee safe and reliable operation of the elevator, lower failure rates and extended life.
2.2 various maintenance system (regularly cycle maintenance check cycle) of similarities, and maintenance of key parts of the body and the specific technical requirements:
(1) the daily maintenance of the system. Applies to the escalator number more concentrated and more, and permanent maintenance personnel to the scene of major projects in the elevator of the daily inspection and maintenance; and of course also fit-owned maintenance workers in user units for maintenance. The specific check content can also be used as responsible for the maintenance work for routine maintenance work sampling of the content in the first check. ① request maintenance personnel daily to lift drivers or administrators understand the elevator usage, and personally run inspection of the elevator and the use of the site, making good day record. ② daily inspection and maintenance of key parts should be placed on the reliability of elevator operation (that is, the correctness of the elevator movement, elevator speed stability and have no trouble), ensure that the lift without fault, safe run. ③ in elevator action of correctness, the main check all button, the signal indication, leveling, elevator and loaded with features. ④ in elevator operation stability, check the elevator runs, the speed is functioning, stable, there are no abnormal noise, door switch door is functioning smoothly etc.
(2) weekly maintenance of the system. Suitable for elevator equipment using frequency is very high, as well as key, key user elevator maintenance work. Of course, the weekly maintenance work is also suitable for maintenance supervisor for routine maintenance quality sampling inspection. ① weekly maintenance work should focus on maintenance of security equipment, elevators and escalators running parts of flexibility. ② in the elevator safety equipment safety and reliability, required to check the maintenance of the elevator door lock the layers, electrical interlock-contact and safety circuit on the safety switch of the reliable and brake performance and the car door security protection devices. ③ elevator operation, main parts and flexibility required to check the maintenance car-door pulley and door the flexibility of all moving parts, as well as motor, worm gear, wheel, rotate the clean lubrication conditions.
(3) monthly maintenance of the system. Suitable for most healthy routine maintenance of elevators. Of course, a monthly inspection and maintenance work the same as a maintenance supervisor and Allied quality inspection personnel on maintenance work quality spot checks, checks of the examination. ① monthly inspection and maintenance work is focused on, check the elevator because of frequent running may be vulnerable to loose, easy-to-wear component (such as car-Mun) of soundness and integrity so that the lift in overall structure, is intact, strong, safe and reliable good working condition. ② in the elevator the fastening parts of firmness, shall check the maintenance of the content is primarily the car floor door bolts, layers, device, automatic door-door guide bracket clamp bolts, DRAY rope head, balanced compensation equipment, electrical control cabinets in the tightening screw, Wells road information devices. ③ to slip scroll wear part of complete and reliability, required to check the maintenance or replacement of content is the main destination layer door pulley, door machine belt, shoe lining of boots, the fuse box core traction, traction rope, etc. ④ course, not checked, check and maintenance of elevators for monthly maintenance, you must check the appropriate day and week to check maintenance requirements (maintenance, check project) included in the monthly maintenance of areas and elevators to conduct a more thorough cleaning and periodic checks, maintenance, maintenance work.
(4) quarter of the maintenance of the system. Suitable for healthy, use frequency lower user elevator maintenance, as well as to perform normal monthly maintenance work is not easy to neglect, omission or off project maintenance. Similarly, the quarterly inspection maintenance content can also be used as a maintenance supervisor and Allied quality inspection personnel in the maintenance work at the time of checking the quality of checks. ① quarter maintained the focus should be placed on the reliability of the work affected elevator parts between gap or relative size checks, adjustment and maintenance, taking into account the day of check, check, monthly checking is negligence, omission of locations. ② quarter maintenance, all moving parts for elevator between gap or relative size inspection, adjustment of main content check adjustment system, access the automatic door machine tool and the Office door and sill level spacing, car-door interlock contact reliable mesh, as well as traction rope between various rope tensioner, brake clearance, cabin the hit the top surface of the plate and buffer range, security-wedge and Rails on either side of the clearance of peace layer accuracy, etc.
(5) the annual maintenance of the system. Applies to the escalator in the Government sector and annual inspection of a routine inspection and maintenance before. Of course, the annual inspection and maintenance work the same as a full-time quality inspection personnel in the annual inspection maintenance work quality control will check content. ① annual inspection and maintenance work is focused on security on the elevator, the reliability, easy to wear parts as well as the various system components important related dimensions in a comprehensive, systematic checks and maintenance work. ② the required annual inspection and maintenance of elevators shall be maintained in the position and main contents are: elevator machine performance and safety reliability checks, tests, wear parts and complete reliability, reliability of work on the elevator to the moving part among important clearance or relative size check, resize, etc.
(6) special inspection maintenance system. Suitable for longer term lift use and/or issue of fault more generally intoLine special inspection maintenance cycle is 3-5 years, of course, depending on the specific use of Elevator, maintenance status vary <或提前或延后>. Similarly, a special inspection and maintenance work as a full-time quality inspection personnel conducted a special maintenance work quality control will check content. ① special inspection of the elevator maintenance work is what we usually say project repair or overhaul, maintenance personnel according to the specific situation to determine lift special inspection and maintenance of content. But the security program (such as speed limiter safety clamp, the safety switch and door circuit protection systems, etc.) must be addressed as a matter of special inspection maintenance will be checked project. ② Although specific conditions are different, the elevator lift special inspection maintenance, repair or overhaul work item of content will vary, but often there are special repair project content: tractor brake, various rope wheels, guide rails, traction rope, car-door, compensator, Wells road information system, control cabinet of various electrical components, such as maintenance or replacement.
To really do a good Elevator equipment maintenance, maintenance work on a regular basis, is a more complex and challenging topic; and elevator equipment maintenance is concerned, it is not a very good or fixed or format. Only one hand in the management and hardware constant improvement and advancement; on the other hand the technical model for all manufacturers of specific technical requirements for the elevator and elevator equipment of specific use to formulate appropriate periodic cycle maintenance plans, and conscientiously implemented, we can really make the elevator equipment through effective regular maintenance, maintenance, and reach the original design and manufacture of standard and technical requirements, and reduce failure rates and extended life of elevator equipment.
