[model utility content]
For addressing the above problem, the utility model provides a kind of process equipment pressurized oil system, include oil groove, oil hydraulic power device, pressure regulator, a plurality of oil hydraulic cylinder, a plurality of operating valve, upper limit valve and worktable, worktable is by oil cylinder pushing and have descending stroke of a upward stroke.Aforesaid oil hydraulic cylinder includes a master cylinder and a pair of auxiliary oil cylinder, between master cylinder and auxiliary oil cylinder, be relation in parallel, and master cylinder has the first oil pocket and the second oil pocket.Aforesaid a plurality of operating valve includes a lift valve, a rate conversion valve and a Decompression valves, be all each other relation in parallel, lift valve and Decompression valves are arranged between master cylinder and oil hydraulic power device, and the rate conversion valve is arranged between auxiliary oil cylinder and oil hydraulic power device.
Therefore, main purpose of the present utility model is to provide a kind of process equipment pressurized oil system, and the control by the design of oil circuit wherein and each operating valve, reach time saving effect.
A purpose more of the present utility model is to provide a kind of process equipment pressurized oil system, and the control by the design of oil circuit wherein and operations valve, make process equipment more easy to use.
[accompanying drawing explanation]
Fig. 1 is this process equipment pressurized oil system working oil path figure schematic diagram.
[embodiment]
The utility model mainly discloses a kind of process equipment pressurized oil system, wherein the basic structure of process equipment and oil hydraulic circuit basic principle are known by those skilled in the technology concerned, therefore, with explanation hereinafter, no longer process equipment and oil hydraulic circuit are done to complete description.Simultaneously, graphic with what hereinafter contrasted, the main expression structural representation relevant with the utility model feature, also do not need according to the complete drafting of actual size, formerly explanation.
Please refer to Fig. 1, for a mode of execution of the present utility model, include oil groove 1, oil hydraulic power device 2, pressure regulator 3, a plurality of oil hydraulic cylinder 4, a plurality of operating valve 5, a upper limit valve 6 and worktable 7, worktable 7 has upward stroke, pressure release stroke and descending stroke.Oil hydraulic cylinder 4 includes a master cylinder 41 and a pair of auxiliary oil cylinder 42, and each other for being arranged in parallel, wherein master cylinder 41 has the first oil pocket 411 and the second oil pocket 412; A plurality of operating valves 5 include a lift valve 51, rate conversion valve 52 and a Decompression valves 53, between each operating valve 5 for being arranged in parallel, lift valve 51 and Decompression valves 53 are arranged between master cylinder 41 and oil hydraulic power device 2, and rate conversion valve 52 is arranged between auxiliary oil cylinder 42 and oil hydraulic power device 2.Pressure regulator 3 includes oil pressure adjusting valve 31, pressure gauge 32 and pressure overload loop 33; Oil hydraulic power device 2 comprises motor 21, oil pressure pump 22 and oil purifier 23.
The described process equipment pressurized oil system of the present embodiment, include first rate of climb and second rate of climb in the upward stroke process, and first rate of climb is greater than second rate of climb.When oil hydraulic power device 2 starts, the process equipment pressurized oil system of the present embodiment enters upward stroke, and now lift valve 51 and oil pressure adjusting valve 31 are driven, and the first oil pocket 411 of master cylinder 41 starts oil-feed, and the worktable 7 of process equipment starts fast rise; After rising to special position, give a slow speed signal, now lift valve 51, rate conversion valve 52 and oil pressure adjusting valve 31 are driven, the speed of upward stroke switches to second speed, now the second oil pocket 412 of master cylinder 41 and auxiliary oil cylinder 42 oil-feeds, worktable 7 slows down the rate of climb, and the second oil pocket 412 and secondary oily 42 cylinders due to master cylinder 41 start oil-feed simultaneously, so process equipment has larger pressure force.Be noted that especially in whole upward stroke, oil pressure adjusting valve 31 is the state in driving all, to guarantee can not produce the problem of oil pressure overload in uphill process.
In addition, when worktable 7, in the process of first rate of climb, when all operations valve 5, all under not driven state, worktable 7 can stop at arbitrary position, and after giving rising signals, worktable 7 continues to rise.
When upward stroke arrives the terminal set, upper limit valve 6 is driven forms path with oil groove 1, and now starts pressure leak process afterwards, and in pressure leak process, only Decompression valves 53 is driven, now the first oil pocket 411 and oil groove 1 conducting of master cylinder 41.
After completing, pressure release enters descending stroke, descending stroke has a lower position, in descending stroke, only lift valve 51 is driven, worktable 7 starts to descend because of the gravity of self, when worktable 7 arrives lower position, all operations valve 5 is all in negative load condition not, and worktable 7 stops at lower position, after giving rising signals, worktable 7 rises once again.
According to the above description, process equipment pressurized oil system described in the utility model, control and oil circuit design by each operating valve 5, make and have two kinds of different rates of climb in worktable 7 uphill process, particularly, when process equipment starts to start, worktable 7 rates of climb are fast, after the speed switching, the speed of worktable 7 slows down and has enough pressure forces simultaneously and processed, and therefore can effectively save the time of processing or commissioning device, more convenient in operation.
The foregoing is only preferably mode of execution of the utility model, not in order to limit interest field of the present utility model; Simultaneously above description, for correlative technology field, special personage should understand and implement, so other do not break away from the equivalence completed under the spirit that the utility model discloses and change or modification, all should be included in the claim scope.
