Setting value then starts lubrication operation, and resets the lap count.
As the further improvement of lubrication control method and device, the starting lubrication operation includes: to calculate lubricant to mend
Charge, starts lubricating utensil, and to be lubricated dose of magnitude of recruitment stops lubricating utensil after reaching.
As the further improvement of lubrication control method and device, the starting lubrication operation includes: that change and starting are moistened
Slide the relevant mark of equipment.
The bad basic reason of prior art lubricant effect is: the opportunity of lubrication (injection lubricant) is scheduled, nothing
Method is selected, and can not more be responded according to the difference of equipment operation state.Since the present invention controls not according to the time,
But according to circle number control, and the operating condition that fixing turn has fundamentally reacted equipment is set, faster, the setting circle of equipment operation
Number reach fastlyer, equipment operation it is slower, if fixing turn reaches more slowly, dynamically adjust lubrication opportunity so as to realize, make
Obtaining lubrication opportunity can be responded according to the difference of operating condition, that is to say, that so that when high speed, between the lubrication of relative low speeds
Every shorter.
The opportunity of lubrication is depended entirely on the circle number that equipment has operated also necessarily can in equipment low-speed running
It is lubricated, will not only occur lubrication as the prior art, deficient lubrication will not occur, guarantee that equipment safety stablizes fortune
Row；When equipment runs at high speed, can be just lubricated while equipment runs at high speed in time, it not only will not be as existing skill
There is deficient lubrication like that in art, lubrication will not occurs, improves lubricant effect.And method control of the invention is simple, is easy
It realizes.
