The present invention is in order to solve the problem, propose a kind of MW class wind turbine group hydraulic system, this device by increasing effective filtration on oil return circuit, coordinated by high pressure filter and return filter, by system with pumping plant is completely isolated comes, fully filter out break, element, pipeline wear and tear the particle and other pollutant that cause; By innovative design on wind power generating set valve block, the valve block structure of built-in filter core and one-way valve can be installed, be combined to form novel filtrating equipment, innovation solve the difficult problem cannot placing traditional return filter because fuel tank upper cover plate is less; Thus effectively ensure that the turbidity test of system fluid, greatly reduce oil contamination and system failure rate.
To achieve these goals, the present invention adopts following technological scheme:
A kind of MW class wind turbine group hydraulic system, comprise system oil-way, high pressure filter and oil return filter mechanism, wherein, the oil feeding line of system oil-way arranges high pressure filter, oil return circuit increases an oil return filter mechanism respectively at the link position place of two Solenoid ball valves and fuel tank, the fluid of whole system is fully filtered, the control unit after oil pump feed mouth, executive component completely and pumping plant isolate and filter;
Described return filter is valve block structure, comprises valve block body, and valve block body inside is filled with filter core.
Oil return circuit return opening is provided with in described valve block body, the filter core mounting hole upper end that oil return circuit return opening is arranged by pipeline connection valve block body inside, filter core mounting hole lower end connects the auxiliary hole that one-way valve connects drainback passage, described pipeline is also communicated with plug-in one-way valve mounting hole, and the lower end of plug-in one-way valve mounting hole is communicated with filter core mounting hole.
In described filter core mounting hole, filter core is set.
The outside of described filter core mounting hole is evenly laid with several filter core fastening flange tapped holes, in order to install the screw of fixing filter core.
Beneficial effect of the present invention is:
(1) factors such as the present invention is from the particularity of hydraulic system of wind power generating set operating mode, considers vibration equipment, and difference variation is large are on the impact of oil contamination in hydraulic system.On the basis of traditional filtering design principle, add oil return filter, the control unit after oil pump feed mouth, executive component isolates with pumping plant completely and filters, fundamentally solution oil contamination and then the high problem of solution rate of fault;
(2) the present invention fully takes into account hydraulic system of wind power generating set small volume, upper cover plate installing space is limited, tradition return filter volume cannot be installed more greatly and the problem such as vibration equipment, innovative design is designed by valve block structure, and combination utilizes Cha Installed formula one-way valve, filter core etc. on valve block, realize the function of oil return filter.Adopt Flange joint, filter element replacing is convenient; Thus solve the problems referred to above;
(3) problem effectively solving hydraulic system of wind power generating set oil contamination and a series of equipment failures caused because of oil contamination, and then improve the generated energy of unit.

Embodiment:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
A kind of novel MW grade wind driven generator machine hydraulic system, it by increasing effective filtration on oil return circuit, coordinated by high pressure filter and return filter, by system with pumping plant is completely isolated comes, fully filter out break, element, pipeline wear and tear the particle and other pollutant that cause; By the structure of the built-in filter core of innovative design on wind power generating set valve block, innovation solve the difficult problem cannot placing return filter because fuel tank upper cover plate is less; Thus effectively ensure that the turbidity test of system fluid, greatly reduce oil contamination and system failure rate.
Realize the problems referred to above by the following method:
1, the system that novel oil return filter coordinates high-pressure filteration is increased;
2, the filtrating equipment innovative design of filter core, one-way valve makeup valve block.
As shown in Figure 1, the basis of traditional design mode high pressure filter increases oil return filter, fully filter out the oil residue that brake wear, hydraulic element wearing and tearing, external contaminant etc. cause, avoid oil contamination to affect product performance.The oil pump feed mouth place of oil return circuit increases return filter, namely between Solenoid ball valve (19.1 and 19.2) and fuel tank, increases a neoteric oil-returning filtering device respectively.
Fig. 2, Fig. 3 are can built-in oil return filter core, plug-in one-way valve thus realize the self-control valve block structure schematic diagram of return filter function, first, from the particularity of hydraulic system of wind power generating set operating mode, consider vibration equipment, the factors such as difference variation is large are on the impact of oil contamination in hydraulic system.On the basis of traditional filtering design principle, add oil return filter, the control unit after oil pump feed mouth, executive component isolates with pumping plant completely and filters, fundamentally solution oil contamination and then the high problem of solution rate of fault.
