Abstract
The utility model discloses a redundant-type hydraulic pressure station comprising an oil tank and a driving oil cylinder. A first hydraulic power unit and a second hydraulic power unit are arranged in parallel on an oil outlet pipe of the oil tank, and the oil outlet pipe and an oil return pipe between the oil tank and the driving oil cylinder are respectively communicated with a rodless cavity oil pipeline of the oil cylinder and a rod cavity oil pipeline of the oil cylinder through a first magnetic exchange valve and a second magnetic exchange valve which are in series connection with each other. A single-pole double-throw switch is arranged on power circuits of the first hydraulic power unit, the second hydraulic power unit, and the first magnetic exchange valve and the second magnetic exchange valve. Redundant design for the components prone to fault is adopted in the redundant-type hydraulic pressure station, so that processing speed in time of the fault is improved, equipment investment is reduced, cost is saved, and benefits of an enterprise are increased.
Description
Technical field
The utility model relates to mechanical field, is specifically related to hydraulic station.
Background technique
Hydraulic station is a kind of equipment that mechanical energy is converted into the pressure energy of hydraulic oil, is widely used in the fields such as aviation, engineering machinery, mining equiment.Concerning the hydraulic station of the waste incineration and generating electricity boiler that is applied to continuous operation, the expense of at every turn again putting stove is higher, so requiring equipment failure rate is zero, and the hydraulic station continuous operation is prone to fault, the processing scheme that in the past adopted is the using and the reserved, namely prepare two hydraulic stations, cause equipment funds to drop into higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of redundance type hydraulic station, can solve prior art for guaranteeing that the continuous operation of production needs to prepare two hydraulic stations and causes the higher problem of equipment funds input.
The utility model is achieved through the following technical solutions:
the redundance type hydraulic station, comprise fuel tank and drive oil cylinder, the oil outlet tube of described fuel tank is communicated with the first power unit, the outlet one tunnel of described the first hydraulic power unit is returned to fuel tank through spill pipe, another road communicates with the first solenoid directional control valve, described the first solenoid directional control valve also respectively with the return tube of fuel tank and the rodless cavity oil pipe that drives oil cylinder, the rod chamber oil pipe communicates, described the first hydraulic power unit advances, the outlet two ends are parallel with the second hydraulic power unit, advancing of described the first solenoid directional control valve, outlet also is parallel with the second solenoid directional control valve, described first, the filler opening of the second solenoid directional control valve is through solenoid valve and first, the outlet of the second hydraulic power unit communicates.
The further improvement of the utility model scheme is that the oil outlet tube of fuel tank is provided with filter.
The further improvement of the utility model scheme is that the return tube of fuel tank is provided with one-way valve.
The further improvement of the utility model scheme is that spill pipe is provided with relief valve.
The utility model advantage compared with prior art is:
The parts that commute breaks down carry out Redundancy Design, have improved the processing rate when breaking down, and have reduced the equipment funds input, have saved cost, have increased the benefit of enterprise.
