Embodiment 1
[0051] 1. Select effective points of measurable parts:
[0052] Select the same type of coal handling machinery and equipment in the national electric power industry within the range of 20° to 50° north latitude: the bucket wheel shaft support hub with the same parameters is used as the effective point 1 of the measurable parts (34 units in 17 companies); the belt conveyor is decelerated with the same parameters The end cover of the input end of the shaft I of the machine is used as the effective point 2 of the measurable parts (50 units in 25 companies); the side wall below the oil level of the oil tank design of the hydraulic system of the luffing mechanism with the same parameters on the bucket wheel machine is used as the effective point 3 of the measurable parts (34 units in 17 companies) ).
[0053] Measure the temperature data of the effective points of the selected measurable parts:
[0054] Under the running state of the machine, measure the bucket wheel shaft suppor...

The invention discloses a method for improving the maintainability of a mechanical device. A same friction pair in a same mechanical device in a same industry or a measurable component having no thermal interaction with a friction pair and having high thermal inertia is selected as an efficient point, and a maintenance scheme is determined by measuring the temperature of the efficient point and judging whether the friction pair component is aged or not by virtue of mathematical statistics. A traditional maintenance mode of after-maintenance and overmuch maintenance is changed by virtue of the predicted maintenance, so that the accuracy for judging the aging of components of the mechanical device can be greatly improved, the information transmission speed is greatly increased, the information transmission range is greatly enlarged, the completeness of the surface of the aged component can be guaranteed, a domino effect is avoided, and the convenience in maintenance can be realized; compared with a traditional maintenance technology, for the method, the overhaul period can be prolonged by four times, the fault stopping rate can be reduced from 2.5 percent to 1 percent, and the maintenance cost can be reduced by more than 60 percent; more importantly, the quantity of damaged components can be greatly reduced, and the quantity of remanufactured components can be greatly increased.
Description
technical field [0001] The invention relates to a method for maintenance of engineering machinery, in particular to a method for improving the maintainability of mechanical equipment, which belongs to the field of maintenance of engineering machinery. Background technique [0002] No matter how perfect the design and manufacture of the machinery and equipment of existing power generation (thermal) power, mining, steelmaking, bulk material conveying docks, tunneling and other enterprises, they will age due to long-term use, storage or idleness. In the prior art, although the temperature is detected, it is hoped that the machine can be maintained at the most suitable time, that is, before the mechanical equipment ages. However, due to empirical judgment, the condition of mechanical equipment cannot be scientifically grasped, which often results in "after-event maintenance" or "surplus maintenance" due to excessive preventive measures.
