Description

A kind of ultra-large type Roots vaccum pump end cap water spacer
Technical field
The present invention relates to the technical field of ultra-large type Roots vaccum pump, especially a kind of ultra-large type Roots vaccum pump end cap water Spacer is not related to its mechanical connecting structure.When Roots vacuum pump operation, by water spacer and the common structure of Roots vaccum pump end cap It is passed through recirculated water in the cavity made, interior components are pumped to Roots vaccum pump and carry out temperature adjusting, the pump housing is made to keep certain temperature, Guarantee that Roots vaccum pump works normally.
Background technique
When the inlet pressure of lobe pump is higher than 1 Torr, outlet and the pressure difference of entrance are likely to be breached 15 ~ 20 Torr, or It is higher.The power of pump is directly proportional to pressure difference.Therefore pressure difference is big, and the power of pump sharply increases, therefore lobe pump delivery temperature, pump The temperature of the temperature of interior part, especially rotor can increase therewith, if do not taken cooling provision (especially to arrange to the cooling of rotor Apply), pump long time running under atmospheric pressure, the thermal expansion of rotor may cause gap disappearance, rotor by wedging, stuck, or even Damage.
So it is found that the temperature change of the Roots vaccum pump pump housing can the working performances such as practical pumping speed to pump have very big shadow It rings, can be related to vacuum pump work normally, especially ultra-large type Roots vaccum pump.The entire Roots vaccum pump pump housing in order to prevent It overheats, by pump body temperature control within the scope of reasonable equilibrium temperature, needs to take pump some temperature regulation measures, often Method is to fill an aftercooler in exhaust side, to adjust delivery temperature and pump body temperature.It also needs to explore in practice The ways and means that temperature adjusting is more carried out to the Roots vaccum pump pump housing, combine, integrated application, multi-facetedly to sieve Thatch vacuum pump body carries out temperature adjusting.
Summary of the invention
The purpose of the present invention is to provide a kind of ultra-large type Roots vaccum pump end cap water spacer, provide more one kind to super Large-scale Roots vaccum pump pumps the product and method that interior components carry out temperature adjusting, to take various temperature regulative mode, more The temperature of the Roots vaccum pump pump housing is efficiently controlled in reasonable range, promotes the efficiency of Roots vaccum pump.
To achieve the goals above, the technical solution of the present invention is as follows: a kind of ultra-large type Roots vaccum pump end cap water spacer, packet Including water spacer integrally is in hollow kidney-shaped mesa-shaped, and the inner cavity of water spacer is in hollow form, and the front end face of water spacer forms front end boss The rear end face of flange, water spacer forms aft end flange flange, and water spacer is socketed on outside vacuum pump end cap, and water spacer passes through rear end It is bolted between male flange and vacuum pump body front end, vacuum pump end cap is fixed at vacuum pump body front end, water Closed cavity is formed between spacer and vacuum pump end cap, forms circulation water inlet and circulating water outlet at water spacer.
The invention discloses a kind of ultra-large type Roots vaccum pump end cap water spacer, ultra-large type Roots vaccum pump end cap water spacers After carrying out temperature adjusting, the technical effect that can generate are as follows: keep lobe pump body temperature further controllable, be maintained at certain temperature In range, guarantee that Roots vaccum pump works normally, while improving the efficiency of Roots vaccum pump to a certain extent.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is sectional view of the present invention.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The invention discloses a kind of ultra-large type Roots vaccum pump end cap water spacers, are different from the prior art and are: including Whole water spacer 1 is in hollow kidney-shaped mesa-shaped, and the inner cavity of water spacer 1 is in hollow form, and the front end face of water spacer 1 forms front end boss The rear end face of flange 2, water spacer 1 forms aft end flange flange 3, and water spacer 1 is socketed on outside vacuum pump end cap 4, and water spacer 1 is logical Later it is bolted between end boss flange 3 and vacuum pump body front end, before vacuum pump end cap 4 is fixed on vacuum pump body At end, closed cavity 5 is formed between water spacer 1 and vacuum pump end cap 4, circulation water inlet 6 is formed at water spacer 1 and recirculated water goes out Mouth 7.
In the specific implementation, the lower section of the water spacer 1 forms circulation water inlet 6, circulation water inlet 6 and closed cavity 5 The top of connection, water spacer 1 forms circulating water outlet 7, and circulating water outlet 7 is connected to closed cavity 5.
In the specific implementation, if being equipped with dry plate stiffener plate 8 between the front end boss flange 2 and aft end flange flange 3, For supporting between male flange 2 and aft end flange flange 3.
In the specific implementation, gap 9 is formed between the front end boss flange 2 and aft end flange flange 3.
In the specific implementation, when water spacer and Roots vaccum pump assemble, it is connected by screw bolts mode, passes through aft end flange method Water spacer and vacuum pump end cap and the Roots vaccum pump pump housing are connected as one by orchid;It is connected by screw bolts mode, it is convex by front end Water spacer and the rear cover of another Roots vaccum pump pump housing are connected as one by lot or luck by which people are brought together orchid 2.Both the original function of former end cap had been maintained, A closed cavity is constructed again simultaneously, for being passed through recirculated water, Fig. 1 and Fig. 2 are shown in the signal of recirculated water circulating direction.Water of the present invention The closed cavity that spacer and Roots vaccum pump end cap jointly constructs go out, major function are in Roots vaccum pump operating status, even It is continuous to be passed through recirculated water, to carry out temperature adjusting to the components in Roots vaccum pump, the pump housing is made to be maintained at certain, controllable temperature In range, guarantee that Roots vaccum pump works normally, while promoting the efficiency of Roots vaccum pump to a certain extent, this is the present invention Design purport where.Two end flanges of water spacer are the front end for being separately connected a pump housing and the rear end of another pump housing.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that Present invention specific implementation is confined to these above-mentioned explanations.For those of ordinary skill in the art to which the present invention belongs, Without departing from the inventive concept of the premise, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to the present invention Protection scope.
