Description
Technical field
The utility model relates to a kind of air filters for wind turbine gearbox, belong to wind power generation gear case
Hydraulic filtering technical field.
Background technique
For wind turbine gearbox in the case where continuously running, temperature can become very high, and highest can achieve 75 degree or so, cause
Gas expansion inside gear-box generates thermal current and needs to be equipped in order not to damage the dynamic oil sealing and lubricating system of gear-box
Air filter, that is, Ventilated cap, the atmospheric pressure inside and outside come balance gear roller box of being ventilated by it.
Existing wind turbine gearbox air filter is directly installed on cabinet, empty after gear-box runs a period of time
There is permeability phenomenon at air filter.Analysis reason has: the gear rotated in one side gear case body drives lubricating oil high speed to fly
It is oozed out after splashing air filter gas outlet；Another aspect lubricating oil forms certain mist of oil at high temperature and enters sky with thermal current
Air filter oozes out after cooling.Existing air filter usually band desiccant, but the humidity of wind turbine gearbox running environment
Greatly, desiccant tends to be saturated after running a period of time, and the function of filtering gradually weakens, and leads to have permeability existing at air filter
As.
To solve the above-mentioned problems, it needs to improve air filter using some measures, existing technology has: 1.
By increasing transition sleeve between gear case body mounting hole and air filter, to improve the height of air filter；
2. increasing air filter in the height of cabinet installation lug, to improve the height of air filter；3. in air filter
Increase an oil baffle at mounting hole below gear case body and be bolted on cabinet wall, prevents to fly in gear-box
The lubricating oil splashed overflows.The analysis prior art has the disadvantage that one side wind turbine gearbox is mounted in narrow cabin, is
Facilitate installation and lifting, the height of air filter is limited, the prior art 1 and 2 is by improving air filter
Height can bring the new problem of installation and lifting aspect to solve oil leakage problem, and user cannot receive；On the other hand, the prior art
3 need to process installation threaded hole in cabinet wall, and cabinet wall is usually arc or narrow space, increases and adds in cabinet wall
The difficulty in work hole, craftsmanship is poor, and mist of oil also can enter air filter with thermal current in cabinet, cannot efficiently solve infiltration
Oily problem.
Summary of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, provide a kind of good manufacturability prepared, knot
Structure is simple, easy to use and reliable, can preferably solve the oil leakage problem of wind turbine gearbox air filter, meet wind power gear
The air filter for wind turbine gearbox to height limitation new demand is installed and lifted to case.
The purpose of this utility model is completed by following technical solution, a kind of air mistake for wind turbine gearbox
Device is filtered, it is mainly made of air filter, flange, O-ring, purifying tube, air inlet, oil outlet, the flange and net
It is mounted on wind power gear box body, and is sealed on mounting surface by the O-ring, the air mistake after changing cylinder welding
Filter is mounted on flange.
As preferred: the air inlet is arranged on the side wall of purifying tube and the thermal current in gear-box is allowed to enter,
The lubricating oil that thermal current a part is formed after the inner wall of the flange and purifying tube is cooling drops to purifying tube bottom, another
Portion gas is discharged by air filter.
As preferred: the purification drum outer wall is that can effectively prevent inner gear of the gear box from rotating splashing lubricating oil to enter
The lubricating oil of the thin-walled cylinder of air filter, the purifying tube bottom flows back into wind power gear box body by oil outlet
It is interior.
The utility model preferably solve because wind turbine gearbox air filter run a period of time after, air filter
The function of filtering gradually weakens the problem of leading to permeability at air filter, while meeting wind turbine gearbox installation and lifting pair
The new demand of height limitation, and the device technique is good, structure is simple, easy to use and reliable, improves wind turbine gearbox
Reliability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 1, a kind of use described in the utility model
In the air filter of wind turbine gearbox, it mainly by air filter 1, flange 2, O-ring 3, purifying tube 5, air inlet 6,
Oil outlet 7 forms, and is mounted on wind power gear box body 4 after the flange 2 and the welding of purifying tube 5, and pass through the O shape
Circle 3 seals on mounting surface, and the air filter 1 is mounted on flange 2.
As shown in the figure, the air inlet 6 is arranged on the side wall of purifying tube 5 and the hot gas in gear-box is allowed to flow into
Enter, the lubricating oil that thermal current a part is formed after the inner wall of the flange 2 and purifying tube 5 is cooling drops to 5 bottom of purifying tube
Portion, another part gas are discharged by air filter 1.
5 outer wall of purifying tube described in the utility model be can effectively prevent inner gear of the gear box rotate splashing lubricating oil into
Enter the thin-walled cylinder of air filter 1, the lubricating oil of 5 bottom of purifying tube flows back into wind turbine gearbox by oil outlet 7
In cabinet 4.
Embodiment: shown in Fig. 1, a kind of air filter of wind turbine gearbox described in the utility model, it mainly by
Air filter 1, flange 2, O-ring 3, purifying tube 5, air inlet 6, oil outlet 7 form.
The flange 2 and purifying tube 5 uses welding procedure, does not need to process installation threaded hole, technique in box house
Property is good, and structure is simple.
The flange 2 is directly installed on wind power gear box body 4, is sealed on mounting surface with the O-ring 3,
It is fixed using bolt presses, good airproof performance, improves reliability.
The air filter 1 is mounted on flange 2, is not needed to increase transition sleeve or is increased cabinet installation lug
Highly, it keeps air filter height minimum, meet wind turbine gearbox installation and lifts the new demand to height limitation.
The air inlet 6 allows the thermal current in gear-box to enter, and thermal current a part is through the flange 2 and purification
The lubricating oil formed after the inner wall of cylinder 5 is cooling drops to 5 bottom of purifying tube, and another part gas passes through 1 heel row of air filter
Out, the lubricating oil in effective cold filtration mist of oil.The diameter of the fuel feed hole 6 and the setting of quantity need to guarantee total circulation
Area is greater than the area of air filter blow vent.
The oil outlet 7 allows the lubricating oil of 5 bottom of purifying tube to flow back into wind power gear box body 4, keeps mist of oil
In lubricating oil recycled inside gear-box, avoid leaking.The diameter of the oil outlet 7 and the setting of quantity need to guarantee profit
Lubricating oil can be flowed back into sufficiently in cabinet, while also be avoided that the lubricating oil to splash in cabinet enters inside purifying tube 5.
The purifying tube 5 is thin-walled cylinder, the profit that outer wall can effectively prevent inner gear of the gear box rotation from splashing
Lubricating oil enters air filter 1, to avoid the permeability at wind turbine gearbox air filter 1.
