Abstract
The utility model discloses a bearing chamber of a primary air fan, comprising a bearing chamber body, an oil-gas pressure relief cover and an oil-gas collecting plate. The oil-gas pressure relief cover is formed by an inner cylinder and an outer cylinder with a top cover; the upper part of the inner cylinder is provided with at least one pressure relief hole which is positioned in the covering range of the outer cylinder with the top cover; the lower part of the inner cylinder and the top part of the bearing chamber body are connected by screw thread; and the oil-gas collecting plate is arranged on the top part of the bearing chamber body. The bearing chamber of the primary air fan effectively solves the potential safety hazard existing in the primary air fan for a long time and ensures the safety of production.
Description
Technical field
The utility model relates to a kind of primary air fan bearing chamber, particularly a kind of can be to the primary air fan bearing chamber of oil gas unloading pressure protection.
Background technique
The bearing lubrication of primary air fan is the main oil pump of dependence equipment itself and the dual pressure lubrication of oil ring in the bearing chamber.Main oil pump is that bearing carries out normal fuel injection in equipment operation, and the oil ring in the bearing chamber carries out rotating band oil simultaneously and is the bearing fuel feeding.When equipment operation after a period of time oily temperature progressively raise, will produce oil gas in the bearing chamber, bearing chamber will produce minute-pressure when oil gas reaches a certain amount of, and bearing chamber seals.Fig. 1 is the schematic representation of existing primary air fan bearing chamber, as shown in the figure, the top of bearing chamber 1 comprises a peep hole, peep hole is by 3 sealings of a sealing cover, because bearing chamber 1 seals, at this moment the oil gas that produces in the bearing chamber 1 will be from the outside seepage of axle envelope of bearing chamber 1 and axle 2, the direction of arrow as shown in FIG..The oil gas of seepage condenses into oil droplet at this place and leaks into the casing of primary air fan.There is thermal insulation layer the casing outside, and oil spill can be piled up in that thermal insulation layer is inner, and the operating temperature of primary air fan is usually more than 326 ℃, will the breaking out of fire phenomenon when oil spill reaches a certain amount of.
For such fault routinely the solution of leakage of oil carry out i.e. outaged equipment, the axle envelope of adjusting the gap between axle envelope and the rotatingshaft or more renewing.But after a period of time, the phenomenon of the very fast axle of generation again envelope place's leakage of oil also causes fire, has had a strong impact on the safe operation of equipment at equipment operation.And after the axle envelope is carried out the routine maintenance, strict measurement has been carried out in the axle envelope and the gap of axle, meet installation code fully.
Summary of the invention
For addressing the above problem, the utility model provides a kind of primary air fan bearing chamber, bearing chamber is changed into atmosphere by closed state be communicated with, and avoids oil gas to reveal the safe operation of support equipment from the axle envelope.
For achieving the above object, primary air fan bearing chamber of the present utility model, comprise bearing chamber body, oil gas venting closure and oil gas collection dish, described oil gas venting closure is made of the urceolus of inner core and band top cover, the top of described inner core is provided with at least one pressure relief vent, described pressure relief vent is positioned at the scope of the urceolus coating of described band top cover, and the bottom of described inner core is connected with the screw top of described bearing chamber body, and described oil gas collection dish places the top of described bearing chamber body.
The position, upper end portion of described oil gas collection dish is higher than the position, underpart of described urceolus.
Primary air fan bearing chamber of the present utility model has solved the long-standing potential safety hazard of primary air fan effectively, has guaranteed the safety of producing.
Description of drawings
Fig. 1 is the schematic representation of existing primary air fan bearing chamber,
Fig. 2 is the schematic representation of primary air fan bearing chamber of the present utility model.
Embodiment
Fig. 2 is the schematic representation of primary air fan bearing chamber of the present utility model.As shown in the figure, primary air fan bearing chamber of the present utility model comprises bearing chamber body 10, oil gas venting closure 30 and oil gas collection dish 40, described oil gas venting closure 30 is made of the urceolus 32 of inner core 31 and band top cover, the top of described inner core 31 is provided with at least one pressure relief vent 33, described pressure relief vent 33 is positioned at the scope that described urceolus 32 coats, and the bottom of described inner core 31 is connected with the screw top of described bearing chamber body 10; Described oil gas collection dish 40 places the top of described bearing chamber body 10.
The urceolus 32 of described inner core 31 and band top cover is formed in one.The height of the urceolus 32 of band top cover is less than the height of inner core 31.Pressure relief vent 33 guarantees that the smooth row of the oil gas of bearing chamber body 10 inside is to the bearing chamber outside.
Because once this blower fan is when routine work, have a large amount of particle suspensions such as pulverized coal particle and dust particle etc. around the equipment in the middle of air, do not blocked and prevented that rubbish from entering bearing chamber in order to guarantee pressure relief vent 31 by foreign matter, therefore pressure relief vent 33 is positioned at the scope of urceolus 32 coatings of described band top cover, and promptly the position, underpart of urceolus 32 is lower than the position of pressure relief vent 33.The urceolus 32 of band top cover can also guarantee to accumulate in earlier the inwall of urceolus 32 when oil gas is discharged, all be collected in the oil gas collection dish 40 when forming oil droplet.The position, upper end portion of described oil gas collection dish 40 is higher than the position, underpart of described urceolus 32.Such layout is equivalent to form a labyrinth shape structure, can guarantee not outer the rushing down of oil gas and the secondary pollution that forms, has guaranteed that also foreign can't enter bearing chamber simultaneously, has guaranteed the normal operation of primary air fan.
Primary air fan bearing chamber of the present utility model is that oil gas venting closure 30 and the original peep hole sealing cover of oil gas collection dish 40 replacements are set at the peep hole place of the bearing chamber of prior art.The closed state of bearing chamber changed into atmosphere be communicated with, the oil gas of generation directly discharges.Promptly the oil gas that progressively raises of the temperature in the bearing chamber produces when primary air fan runs well, and the oil gas that produces no longer is deposited in the bearing chamber but by oil gas venting closure 30 directly in the bearing chamber row outside bearing chamber, assurance oil gas is not piled up in bearing chamber, therefore, as long as the axle envelope meets installation code.Oil gas just can not revealed from the joint of bearing chamber body 10 and axle 20, and the primary air fan bearing chamber just can not cause fire accident because of leakage of oil.
Claims (2)
