Description
Technical field
The present invention relates to a kind of bearing support, relate in particular to a kind of roots blower (Roots pump) and use the sandwich-type multifunctional bearing seat.
Background technique
Roots blower (Roots pump) is the strength source device and the vacuum equipment of extensive use both at home and abroad at present.Produce a large amount of heats during this equipment pressurized air (or vacuumizing), heat transfer is to bearing, and bearing burns in hot environment easily, causes damage of product, and this kind situation becomes the restriction roots blower main cause in working life.So the body of roots blower (Roots pump) all centers on cooling design to a great extent.
In the market, the cooling of roots blower (Roots pump) has following several kinds of modes: the I. water cooling; II. open natural cooling; III. forced air cooling but; IV. adverse current cooling.
I. generally design the bearing support (wallboard) of roots blower, can consider to have the water ring road, guarantee that with cooling water bearing turns round in suitable temperature range.
II. another kind of main flow mode is to adopt open bearing support (claiming " open type wallboard " again), utilizes the partition that is connected of the atmosphere of normal temperature with bearing and body, avoids the high temperature of body to conduct to bearing.
III. forced air cooling is meant the main shaft structure of the roots blower (vacuum pump) of modification, on main shaft, a radiation fan is installed, and fan is followed main axis rotation, produces air-flow, takes away the body heat.
IV. adverse current cooling is mainly used in roots blower (Roots pump, especially three leaf Roots pumps); Use because Roots pump is a negative pressure, no longer include a large amount of ambient airs and be inhaled into body, when reaching certain vacuum and spend; The entry end of Roots pump; Air-flow is extremely thin, and the gas of suction can't provide any cooling action for the high-temperature gas that outlet end compresses repeatedly, so the organism temperature of Roots pump is higher than roots blower far away.And the principle of adverse current cooling is, when utilizing the blower fan rotation, the negative pressure space that produces between impeller sucks extraneous Cryogenic air, reduces the temperature of body.
Above four kinds of modes respectively have shortcoming following:
I. water-cooled is the best type of cooling of present effect, also is the maximum mode of existing market accounting.But water-cooling pattern waste great lot of water resources, and processing cost is higher relatively, and existing market gradually reduces water-cooled demand.
II. open natural cooling is the comparatively another kind of mode of main flow of existing market, but because heat finally can pass through main shaft and be passed to bearing, so its effect is quite limited, under the environment of high pressure-temperature, actual has been sacrifice bearing life and even machine life.Under higher operating mode, still need water-cooled mode to replenish, and its structure is conflicted, and causes it can not be adapted as the water cooled bearing seat with the water cooled bearing stand structure, greatly limitations the development of enterprise product line.
III. forced air-cooled structure need be carried out bigger repacking to product, and has reduced the product main axe intensity.Additional simultaneously mechanism has increased the unstability of product, and external fan also is unfavorable for safety.Most critical be, with the flabellum of main axis rotation, increased the actual power loss of product greatly, wasted a large amount of electric power energies for the conserve water resource, lose more than gain.Except that application circumstances, the product of forced air cooling is rare on the market.
IV. the adverse current type of cooling, the existing market utilization often is shown in vacuum, and its shortcoming is the product body that needs customization special; From the perforate of body both sides, introduce ambient air, strengthened noise; Need external parts such as bleed air line and baffler, complex structure, with high costs.And only can make Roots pump reach the normal temperature of roots blower, the temperature when using for the roots blower malleation descends, and has little significance.
Summary of the invention
The deficiency that the objective of the invention is to address the above problem provides a kind of roots blower to use the sandwich-type multifunctional bearing seat.
In order to solve above technical problem, the technological scheme that the present invention adopts is: a kind of roots blower is used the sandwich-type multifunctional bearing seat, comprises bearing seat, is provided with countersunk head spiro pluging hole, flow channel and two bearing holes in the bearing seat; The countersunk head spiro pluging hole is made up of countersunk head spiro pluging hole, last countersunk head spiro pluging hole, following countersunk head spiro pluging hole, left countersunk head spiro pluging hole and right countersunk head spiro pluging hole under countersunk head spiro pluging hole, the runner on the runner; Last countersunk head spiro pluging hole, following countersunk head spiro pluging hole, left countersunk head spiro pluging hole and right countersunk head spiro pluging hole are distributed on the edge of flow channel successively; The countersunk head spiro pluging hole is two on the runner, and the top that is distributed in two bearing holes is inboard; The countersunk head spiro pluging hole is two under the runner, is distributed in the outside, below of two bearing holes.
After the present invention can finish through time processing; Stop up different countersunk head spiro pluging holes (vent) with countersunk head plug screw (plug); Realize that different air cavitys, air flue, water channel distribute, through simple repacking, application of the present invention makes same roots blower realize water-cooled, air-cooled, vacuum adverse current cooling multiple application such as (roots blower is become Roots pump to be used) according to demands of different; And have the advantage of existing four kinds of types of cooling, better heat-radiation effect concurrently.
