Feedback signal device, and thus opening and closing direction and the time of control oil pump station and magnetic valve；Magnetic valve bottom is provided with by fat liquoring
Gear, smearing rubber is axially lifted with by the parallel gears above at the gear of fat liquoring.
Further, magnetic valve is three position four-way electromagnetic valve, and forward grease outlet and reverse grease outlet are provided with magnetic valve.
Further, smear rubber and use magnetic oil-resistant rubber material, to smear and be provided with multiple oil ducts on rubber.Can be
In the presence of magnetic force, rubber and gear surface adhesive are smeared, while the scattered fat by rubber surface oil duct in rotation process is made
With by grease uniform application to gear surface.
In the system, lubricant grease is expressed into separator by oil pump station, by separator wait pressure be assigned to~it is individual (according to
Oil site requirement) in fuel feeding branch road, its detailed process is：
(1) grease is expressed to separator by oil pump station unification, and grease is supplied into each by each fuel feeding branch road of separator
Oil site, overflow valve is set as 10MPa in the end of each fuel feeding bypass duct, pressure, uniform with the fuel feeding for ensureing each branch road
Continually and steadily.
(2) spring type mechanical accumulator ensures that in closed electromagnetic valve oil pressure over-pressed will not produce damage to equipment in fuel feeding branch road,
And when magnetic valve is opened, lubricating grease can flow out in time under stress, gear is dropped into by the appropriate location of the field of conjugate action.
(3) magnetic valve is three-position four-way valve, when ensure that the rotation clockwise and anticlockwise of gear, can be by grease
It is coated onto in the correct field of conjugate action.Corresponding oil-out can be opened according to the positive hour hands of the job requirement of lowering or hoisting gear or counterclockwise,
And adjusted according to actual speed, opening and closing time of magnetic valve is so as to control the application place and oil quantity of grease.
(4) rubber is smeared, using magnetic oil-resistant rubber material.Tow sides have cloth deep-fried twisted dough sticks line and oil duct.So no matter
Gear is rotated clockwise or counterclockwise, and smearing rubber can all fit in the presence of magnetic force with face of gear, and in the mistake for rotating
Grease is uniformly arrived the field of conjugate action of gear in journey.
The beneficial effect of the invention is：Fat, simple structure low cost are mended in the system energy self-lubricate.Can be according to rising
Or the different operating modes such as decline, and oil-out is adjusted, lubricated the field of conjugate action.Lubricating grease is fuel-displaced according to lifting action Synchronization Control
Waste is avoided, while also reducing the pollution to marine environment.The dispersion smearing mechanism of lubricating grease is simple, highly reliable.
