Description
Technical field
The utility model relates to wind power technology field, particularly relates to a kind of wind power generating set braking system device for recovering hydraulic oil.
Background technique
The hydraulic system of wind power generating set (hereinafter to be referred as wind-powered electricity generation unit) is as driver part, for the braking system (spindle brake and off-course brake) of wind-powered electricity generation unit provides power.Braking system is as hydraulic actuator, for Transmitted chains braking and the yaw system braking of wind-powered electricity generation unit provide braking moment.Yawing brake system when work, because break is oil cylinder pushing form, when having the situation downforce oil of damage, seal ring can overflow, and hydraulic oil constantly gathers, until spill on driftage friction plate, causes the problems such as frictional noise that braking force is not enough and abnormal; Can drop onto in yaw platform and pollute if fluid continues to assemble, while even causing regular maintenance, personnel slip.Spindle brake seepage fluid may drop onto in frame, causes serious disaster hidden-trouble.For the problem of the outside seepage of braking system hydraulic oil, the hydraulic system of wind-powered electricity generation unit adopts return line or oil-collecting bottle two schemes to solve conventionally.
Wherein, the scheme of return line is: by return line, off-course brake and spindle brake drain tap are coupled together and directly receive the hydraulic fluid port that leaks back to of hydraulic station, the advantage of this scheme has two: one, and return line and hydraulic system form a loop, and the hydraulic oil oozing out can not be discharged to and outside hydraulic system, cause environmental pollution; The 2nd, the hydraulic oil oozing out, all the time in hydraulic system inner loop, can not inhaled the problems such as empty, fuel tank hydraulic pressure oil level is too low by initiation solution press pump when indivedual break generation serious leakage.
But also Shortcomings of return line scheme: owing to conventionally having certain height difference between off-course brake and hydraulic station fuel tank, add the siphonage of oil pipe to hydraulic oil in fuel tank, the effusion force feed of some off-course brakes not only cannot turn back to fuel tank, hydraulic oil in fuel tank even can, by suck-back in the oil returning tube of off-course brake, cause very large potential safety hazard.
Oil-collecting bottle scheme is to connect an oil-collecting bottle at the drain tap place of each off-course brake, and effusion force feed is deposited in oil-collecting bottle.The advantage of this scheme is that oil-collecting bottle is corresponding one by one with off-course brake, is convenient to the off-course brake of determining that sealing goes wrong.
But oil-collecting bottle scheme is based on off-course brake good seal, the very little condition of hydraulic pressure oil mass of oozing out designs, in the time that damaging appears in the seal ring of off-course brake, the hydraulic pressure oil mass of oozing out is much larger than the volume of oil-collecting bottle, overflow to oil-collecting bottle and cause hydraulic oil severe contamination yaw platform and the cabin oozed out outward, and form serious disaster hidden-trouble.
Therefore, in each tool advantage, also there is defect separately in existing break effusion force feed recovery scheme, has certain potential safety hazard, need to be optimized existing hydraulic oil recovery scheme.
