Description
Technical field
The utility model relates to a kind of decompressor of vertical mill hydraulic system, reasonably regulates for equalizing pressure of pulling back to vertical mill.
Background technology
The effect of vertical mill in Plate rolling is used to obtain the suitable width dimensions of steel plate, uses the adjustment of AWC function to roll gap to realize the control of width.Its operation principle is: when roll gap closedown or open mode (during screw mandrel action), hydraulic system is to the equalizing pressure of the hydraulic cylinder 70Bar that pulls back, roll gap puts the as-rolled condition (when namely screw mandrel is failure to actuate) that puts in place, hydraulic system is to the equalizing pressure of the hydraulic cylinder 100Bar that pulls back, ball ring contact between edger roll and screw mandrel, screw mandrel is pressurizeed by AWC cylinder as push rod, and compensating cylinder pull-back forces acts on the gap of upper and lower ball ring being eliminated screw mandrel.
But this equipment in use has problems always: because edger roll bearing up-down force is uneven, ball ring has wearing and tearing always, and lower peripheral surface pad is larger than upper ball ring wear extent, the life-span is short, the metallic particles of wearing and tearing not only can block grease channel, outside impact lubrication unstable wear, pressure also can be caused to suppress height and leakage of oil, and the oil pressure therefore how stablizing vertical mill becomes a urgent problem.
Although had decompressor to carry out reduced pressure treatment to hydraulic system, but the valve of pressure-reducing valve can run into fault after long-term use unavoidably in the past, cause stopping and repair, in these faults, have the problem such as locator problem, oil cylinder leakage of oil.Once there is these problems, just need process of stopping, so just impact is caused on production, reduce output.
Summary of the invention
The purpose of this utility model is to provide one can regulate equalizing pressure of pulling back, and realizes the stable operation of vertical mill, and can prevent leakage of oil, avoids the decompressor of the vertical mill hydraulic system of parking process.
The purpose of this utility model is achieved in that
