Abstract
The utility model discloses a blast blower with a high-pressure blast preventing structure, which belongs to the field of mechanical manufacture. The blast blower is characterized in that the blast blower comprises an impeller (1), a wall board (2), a sealing shaft sleeve (3), a venting plug (4), a wind shield (5), a shaft (6) and an oil tank (7). The blast blower has the advantages that the heating effect to lubrication oil in an oil tank by high-speed and high-temperature wind current is thoroughly eliminated, oil temperature is reduced, and the service life of lubrication oil is prolonged. Lubrication oil is prevented from being blown out from the venting plug, so that the consumption of lubrication oil is reduced, and the time for charging lubrication oil is prolonged. Lubrication oil can not be leaked, so that environmental pollution is eliminated.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of blower with anti-high-pressure blast structure.
Background technique
The present roots blower that uses of China is at the rotation speed of fan height, under the high situation of exhaust pressure, distinguished and admirable from the high speed that the blower fan sealing axle sleeve spills, directly be blown into fuel tank by seal clearance, bearing, because this high speed airflow temperature height quickens lubricant oil intensification in the fuel tank, reduce the lubrication effect of lubricant oil, blower fan working life is shortened in acceleration lubricant oil volatilization, and high velocity air is blown into fuel tank simultaneously, the lubricant oil that gear is stirred blows out from venting plug, causes waste and environmental pollution.
Summary of the invention
The purpose of this utility model provides a kind of overcoming the above problems, and adapts to a kind of blower with anti-high-pressure blast structure of new structure of the various industry development needs of China.
Solving the in-problem technological scheme of the utility model is that this a kind of blower with anti-high-pressure blast structure comprises impeller, wallboard, sealing axle sleeve, venting plug, barge board, axle, fuel tank composition.The sealing axle sleeve of ladder-type is sleeved on the axle, and at the rear portion of impeller, front end and wallboard form the labyrinth clearance sealing, barge board be sleeved on sealing axle sleeve second step on, fuel tank and wallboard pass through bolted on connection, and venting plug is housed above.
When blower fan turns round, there is the high speed hot air flow to blow to the fuel tank direction by seal clearance, when running into the step of ladder-type axle sleeve 3, change direction, the direct hole that communicates with atmosphere by wallboard 2 air that bleeds, remaining micro-hot blast, blocked by barge board 5, eliminated heat effect, prevented that simultaneously the lubricant oil that splashes from blowing out befouling environment from venting plug 4 lubricant oil in the fuel tank.
By researching and analysing the characteristics of wind flow, traditional sealing axle sleeve is designed to ladder-type, increase thick sealing axle sleeve rear portion external diameter, change wind direction, simultaneously set up barge board, thoroughly block the distinguished and admirable influence of high speed, thereby effectively reduce the fuel tank temperature fuel tank at the sealing axle sleeve rear portion, increase the working life of lubricant oil, prolong blower fan working life.
Described a kind of blower with anti-high-pressure blast structure, the sealing axle sleeve of use ladder-type has changed the high speed winds flow path direction that leaks, thereby reduces the distinguished and admirable influence to lubricant oil in the fuel tank of high speed.
Described a kind of blower with anti-high-pressure blast structure is set up barge board on sealing axle sleeve, thoroughly block the influence of high speed winds to fuel tank.
Beneficial effect: the utility model has following advantage:
Thoroughly eliminate the distinguished and admirable heat effect of high-speed and high-temperature, reduce the oil temperature, prolong lubricant oil working life lubricant oil in the fuel tank.Prevent that lubricant oil from blowing out from venting plug, save the lubricant oil consumption, prolong refueling time.Do not have oil leakage, stop environmental pollution.
Description of drawings
Fig. 1 is a kind of blower section partial structurtes schematic representation with anti-high-pressure blast structure of the utility model.Form by impeller 1, wallboard 2, sealing axle sleeve 3, venting plug 4, barge board 5, axle 6, fuel tank 7.
Embodiment
Below in conjunction with accompanying drawing a kind of blower with anti-high-pressure blast structure of the utility model is described further.
A kind of blower with anti-high-pressure blast structure of the utility model is made up of impeller 1, wallboard 2, sealing axle sleeve 3, venting plug 4, barge board 5, axle 6, fuel tank 7.The sealing axle sleeve 3 of ladder-type is sleeved on the axle 6, and at the rear portion of impeller 1, front end and wallboard 2 form the labyrinth clearance sealing, and barge board 5 is sleeved on the second step of sealing axle sleeve 3, and fuel tank 7 passes through bolted on connection with wallboard 2, and venting plug 4 is housed above.
When blower fan turns round, there is the high speed hot air flow to blow to the fuel tank direction by seal clearance, when running into the step of ladder-type axle sleeve 3, change direction, the direct hole that communicates with atmosphere by wallboard 2 air that bleeds, remaining micro-hot blast, blocked by barge board 5, eliminated heat effect, prevented that simultaneously the lubricant oil that splashes from blowing out befouling environment from venting plug 4 lubricant oil in the fuel tank.The sealing axle sleeve 3 of ladder-type is sleeved on the axle 6, and at the rear portion of impeller 1, front end and wallboard 2 forms the labyrinth clearances sealing, and barge board 5 is sleeved on 3 the second step of sealing axle sleeve, and fuel tank 7 passes through bolted on connection with wallboard 2, and venting plug 4 is housed above.
When blower fan turns round, there is the high speed hot air flow to blow to the fuel tank direction by seal clearance, when running into the step of ladder-type axle sleeve 3, change direction, the direct hole that communicates with atmosphere by wallboard 2 air that bleeds, remaining micro-hot blast, blocked by barge board 5, eliminated heat effect, prevented that simultaneously the lubricant oil that splashes from blowing out befouling environment from venting plug 4 lubricant oil in the fuel tank.
