How does the elevator repair
Professional personnel should not uninstall electrical appliances at will, in case of electric shock or mistake. The platform should be hoisted and supported when the platform is being repaired under the platform of the platform, so as to prevent the sudden descent of the platform, causing casualties. The overflow valve should not be adjusted arbitrarily. Every element in the hydraulic system works under pressure. Any adjustment of the overflow valve may cause the hydraulic system to operate improperly. There will be unnecessary damage to people, machines and things. In any part of the hydraulic system, the pressure oil must be unloaded first, lest the pressure oil spout and the table suddenly fall. Monthly maintenance A. Roller, shaft and bearing, oil cylinder pin shaft and bearing, arm hinge shaft and bearing, etc.
All parts should be filled with lubricating oil to extend the life of the bearing. The oil and oil level of hydraulic oil. The platform rises all the way up, and in this position, the hydraulic pressure should be 40 to 50 mm above the bottom of the box. Hydraulic oil is a variation of dark, sticky or grit, such as a discovery should be replaced in time (32 # hydraulic oil) Annual maintenance A. check all the hydraulic pipes and connectors. The pipe shall not be broken, the joints shall not be loose, and all the joints must be tightened. Remove and disassemble the descending valve, blow the plunger through compressed air, then load and resettle. C. the elevator hydraulic oil is put in the rejected, tighten the joint remove oil filter, after cleaning, use compressed air is clean, and then back into the tank, and the connecting line. (put on new oil and don't keep using the old oil. Otherwise, the moving parts in the system will accelerate the wear and tear.)
For elevator maintenance the simplest way is to find the manufacturer directly to repair, after all, is their production, repair is good, also save time, our factory is the jinan day machinery, bought two or three years, rarely out of order, maintenance in time, high efficiency, under the baidu search them, you ask yourself, see how.
