Weak current College】 【elevator maintenance management.

<br> <br> Elevators for people developing the use of space. The popularity of the elevator, and as the city's prosperity provides favorable conditions. But the elevator will fail, failure and inconvenience to people. Strengthening the management and maintenance of elevators, .make troubleshooting elevator quickly to restore normal operation, the elevator is very necessary. Do a repair management is the establishment of the elevator maintenance standards and appropriate elevator maintenance management system to ensure that the lift maintenance standards ("smooth implementation. <br> First, .the elevator maintenance standards establish the property company engineering Dept of elevator administrator, based on national standards and corporate area of elevator situation the elevator maintenance standards. Note do not set standards and national standards. The following is a company of the elevator maintenance standards. < .br> <br> (1) room <br> <br> 1 room airflow temperature is between 5-40 ℃, relative humidity is not more than 85 per cent, to ensure that no rain penetration. <br> <br> 2 .rooms in the fore and aft should be normal pressure. <br> <br> 3 room emergency operating procedures, notices, and hung on the obvious. <br> <br> 4 acbin logo clearly visible. <br> <br> 5 .-room door-good, signs in a prominent place clearly linked to. <br> <br> 6 engine room power, Jack good. <br> <br> 7 room shall not live, should be kept clean. <br> < .br> 8 traction wheel on vertical deviation is less than 2.0mm, traction wheel Groove with guide wheel Groove parallel degree deviation is less than 1.0mm. <br> <br> 9 speed limiter adjustment positions should lead to the prohibition on non-labour .office professionals. <br> <br> 10 speed limiter Groove, bushings, wear allowed within (reference GB5972 - 86) runtime is no exception. <br> <br> 11 speed limiter, flexible and reliable safety switches. <br> < .br> 12 speed limiter-safety clamp-safety switch linkage and reliable. <br> <br> 13 traction wheel running direction marked clearly. <br> <br> 14 the bearing flexible runtime no abnormal sound, temperature not higher than 80 ℃ ., working 2500 ~ after replacement of the new oil 3000h. <br> <br> 15 all phases and phase conductor between good insulation, electrical equipment shell grounding good. <br> <br> 16 voltage fluctuation in ± 7% range, frequency .fluctuation ± 2% range. <br> <br> 17 brake braking good, cabin to rated speed to the idling uplink trip upper range loses power, should be able to completely stop. System stop distance not greater than 250cm. <br> < .br> 18 elevator rescue manual loose gate, manual turning operation equipment, should be complete and hang on the wall, not his. <br> <br> 19 traction wheel Groove wear from V-slot bottom 4 ~ 5mm, should be replaced. .<br> <br> (2) Wells road and car <br> <br> ① flexible upper and lower limit switch. <br> <br> ② elastic sliding guide shoe size A, C, top clearance 2mm (2.5 ± 1.5 .) mm. <br> <br> ③ rope combined fixed head meets GB7588-87.923 standards. <br> <br> ④ the average tension wire, cabin guide top distance deviation up to standard. <br> <br> ⑤ to block .pressure plate fixed solid, no rust. <br> <br> ⑥ car top lighting, emergency stop switch, maintenance control switch properly. <br> <br> ⑦ cabin safety form a flexible, reliable switching action. Hall door mechanical and electrical .interlocks and reliable. <br> <br> ⑧ car door's safety edge and opto-electronic protective flexible and reliable. <br> <br> ⑨ signs clear clean, alarm device properly. <br> <br> ⑩ instruction, call of .duty, the selected layer, orientation, and other devices are accurate. <br> <br> (3) pit maintenance reference GB7024.1-86. <br> <br> Second, the elevator maintenance and repair system for the safe operation .of the elevator, Elevator maintenance, regular inspection and repair. Elevator and elevator watch electrician responsible for elevator failure emergency maintenance work, the company engineering Dept managers responsible for elevator maintenance organization monitoring work, and is responsible for establishing the elevator maintenance management system. Elevator .maintenance management system mainly includes: <br> <br> (1) month maintenance system primarily examine the various button is flexible, switch is normal, no noise and odour nuisance, speed brake components are reliable. Maintenance finished filling out the elevator maintenance records .of the month. <br> <br> (2) quarter maintenance system <br> <br> For the main equipment room for maintenance. Such as checking the traction motor is running, there are no abnormal noise; reducer is leaking oil, .gear and traction motor temperature rise over whether; traction motor actuator is reliable; speed feedback device feedback signal has no changes in the control cabinet of the reliability of electrical components in action; the action of the limit switch is reliable. Maintenance finished filling out the .elevator quarter maintenance records <br> <br>.
