Description
Technical field
It the utility model is related to lubricant passage way field, and in particular to the oil circuit of gear-box temperature-sensing valve.
Background technology
With developing rapidly for wind-powered electricity generation industry, unit reliability turns into the important parameter that can not be ignored, and gear-box operation can
It is a crucial ring in whole aircraft reliability by property, therefore ensures that gear-box is reliable, to ensures that unit generation amount has great shadow
Ring.
But the temperature-sensing valve control technology in existing lubricating system there is it is very important the shortcomings that：
1st, most common failure when gearbox lubrication system temperature control defective valve is gear-box operation, temperature control defective valve can cause to lubricate
The oil device that can not be cooled normally cools down, and causes lubricating oil temperature high, the high disorderly closedown of unit report gearbox temperature, loss generates electricity
Amount.
2nd, temperature-sensing valve belongs to easily-consumed products in itself, and projected life can use 2 years, but the complexity of running of wind generating set operating mode
Temperature-sensing valve is non-timely caused often not timed out just to be failed in projected life with safeguarding.Such case often summer more
Prominent, summer temperature is higher, and temperature-sensing valve is chronically at open mode, and copper powder precipitation speed is accelerated in temperature-sensitive bag, accelerates temperature-sensing valve
Failure.Even some owners reflect that a summer needs 2~3 temperature-sensing valves of replacing to us.
Therefore, make and can effectively solve the problem that the technical reform scheme of temperature-sensing valve frequent failure is particularly important, and market
Need badly.
Utility model content
The utility model provides a kind of improvement of gear-box temperature-sensing valve oil circuit, the purpose is to solve prior art shortcoming, makes
Lubricating oil is made instantly available cooling, is effectively improved the problem of temperature-sensing valve frequent breakage is brought, and in the winter time low temperature when protect cooler.
A kind of improvement of gear-box temperature-sensing valve oil circuit, including gear-box temperature-sensing valve, distributor, cooler, it is characterised in that：
The entrance of the low-temperature outlet connection cooler of gear-box temperature-sensing valve, the hot outlet connection cooler of gear-box temperature-sensing valve enter
Mouthful, the entrance of the outlet connection distributor of cooler；A safety valve is installed in parallel with cooler, the entrance connection of safety valve is cold
But the entrance of device, the outlet of the outlet connection cooler of safety valve.
It is of the present utility model to be beneficial in that：
A safety valve is installed in parallel with cooler, is forcing temperature-sensing valve exit lubricating oil flowing to the same of cooler
When, it can effectively protect the blockage problem of the cooling fan in cooler.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model structure chart.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below
Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the utility model, for this area
For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings
Example.
As shown in Figure 1：
The entrance of gear-box temperature-sensing valve 1 is connected with gear-box filter.
The low-temperature outlet 11 of gear-box temperature-sensing valve 1 connects the entrance of cooler 2, the hot outlet 12 of gear-box temperature-sensing valve 1
Connect the entrance of cooler 2, the entrance of the outlet connection distributor 3 of cooler 2.
The outlet of distributor 3 is connected with gear-box.
A safety valve 4, namely the entrance of the entrance connection cooler 2 of safety valve 4, safety are installed in parallel with cooler 2
The outlet of the outlet connection cooler 2 of valve 4.
During normal temperature, temperature is not high, and before gear-box temperature-sensing valve 1 is opened, a lubricating oil part is through gear-box temperature-sensing valve 1
Low-temperature outlet 11 flows into cooler 2, flows into distributor 3 after cooling and enters back into gear-box, another part flows from hot outlet 12
To cooler 2, distributor 3 is flowed into after cooling and enters back into gear-box；Temperature raises, and gear-box temperature-sensing valve 1 starts to open, from low
The lubricating oil of the outflow of temperature outlet 11 is reduced, and the lubricating oil flowed out from hot outlet 12 increases；Temperature is increased to gear-box temperature-sensing valve 1
After fully opening, low-temperature outlet 11 is closed, and lubricating oil only flows to cooler 32 from hot outlet 12, flows into after cooling
Distributor 3 enters back into gear-box.
Namely in summer high temperature, this scheme forces oil circuit all to flow to cooler 2, and lubricating oil must just enter after supercooling
Enter distributor 3 and enter back into gear-box, thus be avoided that gear-box temperature-sensing valve 1 fails to open because of long-term open, do not have again
Lubricating oil caused by replacing is possible in time is uncolled just to flow to the accident that distributor 3 enters gear-box with the condition of high temperature.
Winter environment temperature is low, and when oil temperature is relatively low, this scheme still forced feed lubrication oil all flows to cooler 2, but oily
When the low cooling fan that causes to a certain extent in cooler 2 of temperature is internally-damped excessive, at this moment the pressure of fluid can open with it is cold
But the safety valve 4 in parallel of device 2, after safety valve 4 is opened, fluid is directly entered without subcooler 2 but after passing through safety valve 4
Distributor 3, gear-box is entered back into, can so play the function of protection cooler 2, avoid winter low temperature oil from causing in cooler 2
Cooling fan block；The program reduces the problem of human intervention oil circuit moves towards, and avoids because the factors such as personnel's replacing cause
The problem of winter does not safeguard and damages cooler 2 in time.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments
State bright, professional and technical personnel in the field is realized or using the utility model.A variety of modifications pair to these embodiments
It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality
In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this
These embodiments shown in text, and it is to fit to the most wide scope consistent with principles disclosed herein and features of novelty.
