Background technique
At present, the hydraulic system on the steel rolling production-line has following characteristics: pipeline is long, caliber is big, system pressure is high; The fuel tank volume is big, big with oil mass.Cold filtration system in the hydraulic system on traditional steel rolling line as shown in Figure 1, this system comprises: recycle pump 12, motor 13, fuel tank 11, cooling system 14 and filter 15.Wherein, motor 13 links to each other with recycle pump 12, the filler opening of recycle pump 12 links to each other by the oil outlet of pipeline with fuel tank 11, and the oil outlet of recycle pump 12 links to each other by the filler opening of pipeline with cooling system 14, and the oil outlet of cooling system 14 links to each other with the filler opening of filter 15; The oil outlet of filter 15 links to each other by the filler opening of pipeline with fuel tank 11.
The working principle of said system is: recycle pump 12 under motor 13 drives the hydraulic oil in the fuel tank 11 flowed through successively cooling system 14 and filtration system 15, realization is to the cooling and the filtration of hydraulic oil, and the filler opening of hydraulic oil that will be behind cold filtration by fuel tank 11 enters fuel tank, the recycle pump reciprocation cycle just can be so that the hydraulic oil in the fuel tank keeps good user mode.
Because the effect that above-mentioned hydraulic system only plays cooling and filters hydraulic oil, and reservoir capacity is big, and consuming time more with the general a large amount of repairings of oil strain dolly, and each hydraulic station need be equipped with the oil strain dolly of a special use, the increase equipment cost.
The model utility content
In view of this, the utility model provides hydraulic system, and to make things convenient for repairing, the use that reduces the oil strain dolly reduces equipment cost.
For achieving the above object, the utility model provides following technological scheme:
A kind of hydraulic system, comprise recycle pump, motor, fuel tank, cooling system, filter and control valve, wherein, described recycle pump links to each other with described motor, the filler opening of described recycle pump links to each other with the oil outlet of described fuel tank, and the oil outlet of described recycle pump links to each other with the filler opening of described cooling system; The oil outlet of described cooling system links to each other with the filler opening of described filter; The oil outlet of described filter links to each other with the filler opening of described fuel tank; The oil outlet of described fuel tank is provided with the repairing pipeline, and this repairing pipeline is provided with second control valve.
Preferably, in above-mentioned hydraulic system, described recycle pump fuel sucking pipe first control valve of connecting, described first control valve links to each other with the oil outlet of fuel tank.
Preferably, in above-mentioned hydraulic system, described first control valve and described second control valve are high-pressure ball valve.
From technique scheme as can be seen, directly on original pipeline, make improvements among the utility model embodiment, increase the repairing pipeline at the fuel tank filler opening, can directly refuel by the repairing pipeline, and do not need to use the oil strain dolly, therefore hydraulic station does not need the repairing dolly is provided, and the expense of single repairing pipeline the expense than repairing dolly is low far away, therefore reduced the cost of equipment.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of hydraulic system in the prior art;
The structural representation of the hydraulic system that Fig. 2 provides for the utility model embodiment.
Embodiment
Hydraulic system among the utility model embodiment is to improve on original hydraulic system, has realized repairing by increasing several parts, therefore, directly gets final product by this repairing pipeline of use when hydraulic system is carried out repairing, and need not by the repairing dolly.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described.
The utility model embodiment discloses a kind of hydraulic system, and to make things convenient for repairing, the use that reduces the oil strain dolly reduces equipment cost.
This hydraulic system, as shown in Figure 2, comprise recycle pump 22, motor 23, fuel tank 21, cooling system 24, filter 25 and control valve, wherein, recycle pump 22 links to each other with motor 23, the filler opening of recycle pump 22 links to each other with the oil outlet of fuel tank 21, and the oil outlet of recycle pump 22 links to each other with the filler opening of cooling system 24; The oil outlet of cooling system 24 links to each other with the filler opening of filter 25; The oil outlet of filter 25 links to each other with the filler opening of fuel tank 21; Also be provided with repairing pipeline 28 on the oil outlet of fuel tank 21, this repairing pipeline 28 is provided with control valve 27.
In the above-mentioned hydraulic pressure cooling system, recycle pump 21 can be screw pump, blade hydraulic pump or gear pump, and power is big during owing to the gear pump operation, good stability, so the preferential gear pump that adopts among the utility model embodiment.Because the workload of hydraulic system is big in the steel rolling process, so hydraulic oil adopts water-cooled usually when cooling, hydraulic oil flow is realized lowering the temperature behind cooling system, and the filtration by filter filters out the waste residue in the hydraulic oil then.
Above-mentioned hydraulic system can realize that two kinds of actions comprise normal state and repairing, and wherein, course of normal operation is: closed control valve 27, and open control valve 26, oil circuit is switched on the proper functioning oil circuit; Recycle pump 22 under motor 23 drives, the hydraulic oil in the fuel tank 21 flowed through successively cooling system 24 and filtration system 25, realization is to the cooling and the filtration of hydraulic oil, and the filler opening of hydraulic oil that will be behind cold filtration by fuel tank 21 enters fuel tank 21, recycle pump 22 reciprocation cycle just can be so that the hydraulic oil in the fuel tank 21 keeps good user mode; When the repairing state, opening controlling valve 27, and closing control valve 26 just can be realized repairing by repairing pipeline 28.
Directly on original pipeline, make improvements among the utility model embodiment, increase the repairing pipeline at the fuel tank filler opening, can directly refuel by the repairing pipeline, and do not need to use the oil strain dolly, therefore hydraulic station does not need to provide the repairing dolly, and the expense of the single repairing pipeline expense than repairing dolly far away is low, has therefore reduced the cost of equipment.
