Abstract
The utility model belongs to field of vacuum, more particularly to a kind of lobe pump with water cooling interlayer, lobe pump with water cooling interlayer, in the hollow interlayer that the setting of the rear end cap of lobe pump, rear side cover, the pump housing, front side cap and drive end bearing bracket connects, in the first hollow interlayer outlet of rear end cap setting, in the second hollow interlayer outlet of drive end bearing bracket setting.This is newly filled with novel water cooling interlayer leads to entire pump case, and heat dissipation area is big, can be passed through the coolants such as water or oil and be cooled down, and cooling efficiency is high and very simple and convenient；Without individually setting cooling coil, simple in structure, sealing and reliability are high for gear and bearing.
Description
Technical field
The utility model belongs to field of vacuum, and in particular to a kind of lobe pump with water cooling interlayer.
Background technology
Lobe pump is a kind of two-spool positive-displacement vacuum pump, and during acting, gas compression can be produced with when conveying
Heat amount and gear and bearing can also generate heat in operation process, these heats generated can pass to rotor and the pump housing
On；Part expansion rate can be caused to differ and the event such as stuck, shaft sealing leakage, vacuum decay and bearing damage once temperature is excessively high
Barrier.Gear and bearing are usually all to separate the both ends for being enclosed in lobe pump with rotor and the pump housing, are moistened using vacuum oil
Sliding and cooling, and vacuum oil takes away heat by water cooling coil pipe, this type of cooling reliability is not very high, and cooling coil is easy
There is rupture and leakage phenomenon.
The type of cooling of pump internal rotor and gas is mainly the following at present：Water-spraying control, Oil injection cooling, in exhaust outlet
Water cooling coil pipe is added to cool down, reflux cooling, rotor are passed through cooling oil with hollow shaft after exhaust outlet adds condenser cooling discharge gas
Or water is cooled down.Water spray or Oil injection cooling, which can generate steam, influences rate of air sucked in required, while can also use water or oily entrained gas
Operating mode be restricted；Exhaust outlet adds water cooling coil pipe to cool down, and only smaller effect is not fine to heat-transfer surface；Be gas-cooled the cooling side to flow back
Formula can cause efficiency to decline；With the type of cooling structure too complex of hollow shaft, it is rarely employed at present.
Invention content
The utility model in view of the deficiencies of the prior art, proposes that a kind of heat dissipation area is big, cooling efficiency is high, applied widely
The lobe pump with water cooling interlayer, using following technical proposals：
A kind of lobe pump with water cooling interlayer, in the rear end cap of lobe pump, rear side cover, the pump housing, front side cap and drive end bearing bracket
The hollow interlayer of connection is set, in the first hollow interlayer outlet of rear end cap setting, in the second hollow interlayer outlet of drive end bearing bracket setting.
Further, the first hollow interlayer outlet is water inlet, and the second hollow interlayer outlet is water outlet.
Further, the first hollow interlayer outlet is water outlet, and the second hollow interlayer outlet is water inlet.
Specifically, in the first hollow interlayer outlet or the second hollow interlayer outlet setting hand-operated valve.
Specifically, the junction between the rear end cap of lobe pump, rear side cover, the pump housing, front side cap and drive end bearing bracket is respectively provided with
Fluid sealant or gasket.
This newly with it is novel the advantages of be：1st, water cooling interlayer, which fills, leads to entire pump case, and heat dissipation area is big, can be passed through water or oil
Etc. coolants cooled down, cooling efficiency is high and very simple and convenient；2nd, gear and bearing are tied without individually setting cooling coil
Structure is simple, sealing and reliability are high；3rd, the You Heshui of cooling will not entrained gas, it is applied widely；4th, without reflux or steaming
The influence to pumping performance such as vapour, lobe pump are more efficient；5th, water cooling interlayer can play the role of sound insulation and noise reduction, equipment fortune simultaneously
Row is quieter.
Description of the drawings
Fig. 1 is the axial cross-sectional views of the utility model；
Fig. 2 is the transversal profile schematic diagram of the utility model；
Fig. 3 is the structure diagram of gasket.
Specific embodiment
Fig. 1 is the axial cross-sectional views of the utility model；Fig. 2 is the transversal profile schematic diagram of the utility model.Such as Fig. 1
Shown in Fig. 2, a kind of lobe pump with water cooling interlayer, in the rear end cap 10 of lobe pump, rear side cover 11, the pump housing 12, front side cap
13 set the hollow interlayer 1 connected with drive end bearing bracket 14, in first hollow interlayer outlet 2 of the setting of rear end cap 10, are set in drive end bearing bracket 14
Put the second hollow interlayer outlet 3.
Entire pump case is divided into inside and outside two layers by hollow interlayer 1, and inside and outside two layers of junction is bolted, hollow
The rib (not shown) that setting is vertically connected in interlayer 1, rib casting and forming together with internal layer and outer layer, the effect of rib
It is that two layers inside and outside being separated by hollow interlayer 1 is connected, cooling water is filled by hollow interlayer 1 leads to entire pump case, so as to
Realize entire heat dissipation effect of the pump with water cooling interlayer.
The first hollow interlayer outlet 2 of the present embodiment is water inlet, and the second hollow interlayer outlet 3 is water outlet；Certainly,
Can take the first hollow interlayer outlet 2 as water outlet, the second hollow interlayer outlet 3 is water inlet, in the first hollow interlayer outlet or
Second hollow interlayer outlet setting hand-operated valve 4.Fig. 3 is the structure diagram of gasket, as shown in figure 3, in the rear end of lobe pump
Junction between lid, rear side cover, the pump housing, front side cap and drive end bearing bracket is respectively provided with fluid sealant or gasket 5, it is ensured that entire interlayer is close
Feng Xing, it is not easy to leak.
This newly with it is novel the advantages of be：1st, water cooling interlayer, which fills, leads to entire pump case, and heat dissipation area is big, can be passed through water or oil
Etc. coolants cooled down, cooling efficiency is high and very simple and convenient；2nd, gear and bearing are tied without individually setting cooling coil
Structure is simple, sealing and reliability are high；3rd, the You Heshui of cooling will not entrained gas, it is applied widely；4th, without reflux or steaming
The influence to pumping performance such as vapour, lobe pump are more efficient；5th, water cooling interlayer can play the role of sound insulation and noise reduction, equipment fortune simultaneously
Row is quieter.
