Regular maintenance of elevator equipment
As we all know , elevators and other mechanical and electrical equipment , need regular inspection , maintenance and repair . Through regular maintenance of elevator equipment , maintenance, you can maximize reach the elevator and in the original design , manufacturing standards and technical requirements ; and ensure the security and reliable operation of the elevator equipment , reduce the failure rate and extend the life of the elevator equipment. But how to effectively carry out regular inspections of the elevator equipment , maintenance and repair , which is each elevator manufacturers, elevator installation Maintenance units and users are concerned about the issue very seriously and following the issue , talk about some personal views and understanding, to discuss with you , questionable.
Establish a management system in a report on the work of the management and maintenance of hardware applications , hardware conditions continue to improve
Maintenance work on the management of applications and hardware , installation repair and maintenance of each unit should establish a complete system on a regular basis to ensure the quality of repair and maintenance work management systems and measures ; and hardware conditions continue to improve , improve the efficiency of repair and maintenance work , quality and customer satisfaction.
1.1 are required to establish personal responsibility to make the repair and maintenance work documentation , written confirmation of management and users , supervision and management approaches closely together.
( 1 ) Due to the uniqueness of repair and maintenance work, and determines that it has a large workload scalability , Maintenance and repair and maintenance work in the field of working time is not easy to control, management features, and therefore , must be regularly corresponding dimension Potier inspection , maintenance and repair and other work , namely the responsibility to the relevant personnel . In this way, can mobilize and improve the initiative, flexibility and responsibility Maintenance personnel working on site ; can be really strengthen the repair and maintenance work on site .
( 2 ) Maintenance work and its effect is good or bad , you have the final say ; let Maintenance personnel to regularly repair and maintenance of working conditions and the results reported in writing to the user , and the user 's signature recognition , and the results back company ( bottom left archive ) . In this way, both for repair and maintenance work carried out effective supervision and management , but also improve user satisfaction .
1.2 Users are required to establish regular visits to collect user feedback , and quality checks Maintenance work , supervision and management system.
( 1 ) shall establish specialized management system of regular visits sent users to obtain user feedback, the user gets the / site information first-hand information , and timely feedback to the design and manufacturing technologies , installation and other departments for product quality and improved work ; and dynamic tracking , handling questions or complaints from users to improve customer satisfaction.
( 2 ) Of course, the oversight of repair and maintenance work , supervision or confirm the user alone is not enough ( after all, because users are not professionals ) . Periodic sampling to be taken by the responsible leadership and Maintenance work Maintenance Supervisor , and a full-time quality inspection ( inspection ) occasional special inspectors combination of approaches to manage. Regular Maintenance work can ensure strict technical regulations conducted by the security dimension , and thus the periodic repair and maintenance work ( attendance , safety, quality and service, repair and maintenance , etc. ) to implement effective monitoring, control and management.
1.3 Maintenance ladder required to establish a user profile - ie Maintenance ladder database management system to improve the efficiency of repair and maintenance management.
( 1 ) Maintenance ladder for each user must create a user profile , especially just starting to use the elevator, use the elevator and all the important parts ( eg door systems, electrical control systems, mechanical systems, etc. ) for failure case, the input dimension Potier database management system , and then classify , statistics and analysis. Thus , you can find out the cause of the high failure rate of the elevator , and "right" , and constantly improve the quality of products and quality installation repair and maintenance work to improve the reliability of the elevator equipment , reducing the failure rate of the elevator .
( 2 ) can be based on user profiles created using the elevator accumulation and fault conditions , as well as repair and maintenance work ( including replacement parts ) and other raw data . These data through statistical analysis of the factors affecting the reliability of the elevator ( such as computer crashes, easy to wear or faulty parts, etc. ) , ahead of pretreatment or replacement of wearing parts ; take positive , preventive maintenance maintenance measures , repair and maintenance work to improve the efficiency and user satisfaction .
( 3 ) can put the daily work routine data Maintenance personnel , maintenance records, and the use of user ladder , failure and replacement parts, etc. ( including electric / escalator inspection and acceptance time, cost situation etc. ) , enter the security dimension ladder database management system. Conducive to strengthening oversight of the Maintenance personnel work , control and management , but also conducive targeted to identify specific Maintenance work cycle of the user elevator formulate Maintenance plan or medium-sized repair plan , but also conducive to the management and implement specific management measures.
1.4 pairs qualified user units ( such as elevators relatively large number of units , users, or regional concentration ) , using remote monitoring / surveillance system, 24-hour hotline call repair service, improve user satisfaction.
( 1 ) remote monitoring / surveillance system capable of operation, fault and maintenance of elevators , etc. timely dynamic monitoring , recording, in order to effectively implement 24h hotline call repair service, improve customer satisfaction , and to lay a solid foundation material conditions .
( 2 ) remote monitoring / surveillance system is also able to work Maintenance personnel ( such as repair services, such as timeliness and maintenance time case ) effectively monitor, manage , can greatly improve the efficiency of repair and maintenance work , quality, rationalization and scientific management in favor of repair and maintenance work.
2 to develop specialized technical inspection and maintenance procedures regularly cycle is technically
Technically, should develop specific models for a variety of specific technical regulations elevator inspection and maintenance of a regular cycle , and strictly enforced , in order to effectively guarantee the elevator equipment technically periodic inspection , quality service and maintenance work.
2.1 for the case of different types of features and user- specific elevator used to formulate the need for inspection and maintenance of specialized technical regulations periodic cycles:
( 1 ) lift equipment and other electromechanical devices, which require the use of the environment , the use of inferior frequency different situations , take a different maintenance cycle , in order to maximize the elevator to ensure safe and reliable operation of equipment, reduce the failure rate and prolong equipment life for .
( 2 ) usually lift regular cycle maintenance cycle , there are daily inspection , weekly inspection , monthly inspection , quarterly inspection , inspection, seizure of six ways for different types of situations and user specific features of the elevator used to formulate a special inspection content or maintenance program is required. Because each maintenance system , the way , has its own priorities and specific content on the front and rear aspects are closely linked to each other and are closely linked, maintenance personnel must frequently inferior status under the existing circumstances and use the elevator to develop the specific maintenance ladder way , then carefully and strictly according to technical regulations and the development of maintenance programs performed in order to truly ensure safe and reliable operation of the elevator , reduce the failure rate and extend the life of purpose.
2.2 the maintenance system ( periodic maintenance inspection cycle cycle ) the similarities and differences , as well as maintenance of key parts of its specific technical requirements:
( 1 ) Daily inspection and maintenance system. Number of units applicable to lift more concentrated , more, and daily inspection and maintenance of major projects elevator scene Permanent Maintenance personnel ; course is also suitable for the user 's self- repair and maintenance units ladder maintenance work . The specific contents can be checked as the leader responsible for repair and maintenance work Maintenance work routine sampling of the contents of the first seizure . ① Maintenance personnel required to lift a daily driver or administrator for elevator use, and personally visited each site to check the operation of the elevator use , make day record. ② daily inspection and maintenance of key parts should be placed on the reliability of the elevator running ( ie, whether the fault elevator operation stability and correctness of the action , the speed of the elevator ) , to ensure that the elevator without fail safe operation. ③ the correctness of the action in the elevator running , mainly to check each button , the signal indicator, leveling , elevator operation , ultra- loaded with features and so on. ④ run stability in the elevator , the elevator is running the main examination , the speed is normal, stable , with or without abnormal noise when the door switch door is normally smooth and so on.
( 2 ) weekly inspection and maintenance system . Elevator equipment suitable for very high frequency , and key , the key user units elevator maintenance work. Of course, the weekly inspection and maintenance work content is also suitable for repair and maintenance supervisor to check the contents of the daily repair and maintenance quality sampling work. ① weekly inspection and maintenance work focus should be placed on inspection and maintenance of the elevator safety device , as well as flexibility of operation of the elevator parts. ② In the case of elevator operation safety and reliability aspects of safety devices , mainly layers required inspection and maintenance elevator door locks , electrical contacts and safety interlock safety switch for each circuit reliability and performance, and brake the car door safety device . ③ parts for elevators operating flexibility , the main layer required inspection and maintenance of the car door pulley block and door flexibility of moving parts , as well as motors, worm gear , steering wheel and other rotating cleaning and lubrication .
( 3 ) Monthly inspection and maintenance system. Elevator running well for most routine maintenance work . Of course , the content of the monthly inspection and maintenance work can serve as a full-time Maintenance Supervisor and quality inspection personnel to carry out repair and maintenance work quality checks , check the contents when tested . ① focus on the monthly inspection and maintenance work is to check the operation of the elevator which may be due to frequent loosening , wear parts ( eg door sedan layer ) of solidity and integrity of the elevator in the overall structure is intact , firm, secure good working condition. ② in the elevator firm in terms of the fastening parts , maintenance must check the contents of the car throughout the main floor door bolts, door since the complex gate layer device , rail bracket plate bolts, traction Sheng Sheng heads, balance compensation devices, control cabinets each electrical set screws , wells and information devices. ③ due to slip on a complete roll wear parts , reliability , maintenance or replacement shall check the contents of the main floor is the car door pulley slider door belts, boots shoe lining , each fuse fuse traction , traction wire rope . ④ course, did not carry out daily inspection and maintenance of elevators weekly inspection , during the monthly maintenance , you must check the contents of the corresponding day and weekly inspection and maintenance work requirements ( maintenance, inspection items ) included in the scope of the monthly maintenance work , and to conduct a more comprehensive elevator hygiene and regular inspection and maintenance of the maintenance work.
( 4 ) Quarterly inspection and maintenance system. Good condition suitable for operation , the user using the low frequency of maintenance of the elevator , and to perform normal maintenance work is not carried out monthly of negligence or omissions out maintenance projects. Similarly, the quarterly inspection and maintenance work content is also available as a full-time Maintenance Supervisor and quality inspectors check the contents of repair and maintenance work during quality checks when . Focus ① quarterly inspection and maintenance work should be checked with the elevator on the impact of the various components of the gap between the reliability or relative size of the adjustment and maintenance , taking into account the date of the seizure, when the weekly inspection , monthly inspection negligence, omission place . ② maintenance in the quarter , with the gap or the relative sizes of the various moving parts of an elevator between the checks , the main contents are adjusted to adjust the automatic door system check , knife gate and landing door sill spacing layers , electrical interlock door sedan layer the degree of engagement of the tensioner reliable contacts , as well as traction rope rope between each gap brakes , the car hit the board on heavy equipment and the top surface of the buffer distance , embedded security clearance on both sides of the wedge and rail peace layer precision .
( 5) The annual inspection and maintenance system. Suitable for routine checks of government departments in the elevator before the annual maintenance . Of course , the content of the annual inspection and maintenance work the same as the contents will be seized during the annual inspection repair and maintenance work full-time when quality inspection quality inspection personnel. Focus ① annual inspection and maintenance work is that the elevator safety and reliability , easy to wear and spare parts related to the size of the various system components important to conduct a comprehensive inspection , system maintenance work. ② annual inspection and maintenance of elevators , the site must be inspected and maintained main contents are: lift overall performance , safety and reliability for inspection , testing, wear parts for reliability and complete replacement of the affected elevator reliable important with the gap or the relative sizes of the various moving parts between checks , adjustments and so on.
( 6 ) special inspection repair and maintenance system. Longer period applicable to the use of elevators and / or questions fault conditions more generally conduct a special inspection and maintenance period of 3 to 5 years, of course , based on the specific use of elevators , maintenance situation varies < or earlier or later > . Similarly, the special inspection and maintenance work content will be seized as a full-time content inspection personnel performing quality repair and maintenance work of the special quality inspection when . ① special inspection of the elevator repair and maintenance work is what we usually say that the project to repair or overhaul , repair and maintenance personnel to determine the need for special inspection of the elevator repair and maintenance of content according to the specific situation . But it comes to the safety of the project ( such as the governor of the safety gear , safety circuit of each switch , door protection systems, etc. ) must be used as special inspection repair and maintenance of the project will be seized . ② While the specific conditions of different elevators , special inspection of the contents of the elevator repair and maintenance projects that repair or overhaul work will vary, but common special repair project content: hoisting machine brake , various sheaves , rails , traction rope, car layer door , compensation devices , wells and information devices, control cabinets and other electrical components of each inspection and maintenance or replacement.
Really want to do regular maintenance of elevator equipment , maintenance work is a complex and challenging task ; and on the maintenance of elevator equipment is concerned, it was never a good or regulations or fixed format . Only one hand in the management and continuous improvement and hardware to improve ; hand technically specific manufacturers use specific models and technical requirements of the elevator lift equipment , to develop an appropriate periodic inspection and maintenance plan cycle and be careful implementation , in order to really make the elevator equipment through effective regular maintenance , maintenance, reach the original design , manufacturing standards and technical requirements , and reduce the failure rate and prolong the life of elevator equipment .
