Description
Technical field
The utility model relates to the machinery field of sealing technology, refers in particular to the mid-sealing structure unit of a kind of pump housing.
Background technique
The product majority that uses in the every profession and trades such as biogas and steam at present is air ring type vacuum pump such as the lateral flow type blower fan of preposition bearings means of fixation, and most of preposition bearing structure does not have complete isolation design mode with the interior working medium of cavity on the existing market.When working medium does not have complete isolation design in preposition bearing structure and the cavity, enter working medium in the air ring type vacuum pump cavity such as water vapor, biogas or other from the external world, directly enter in the bearing that runs up by the space, its internal grease is easily run off, overflow the external world, also make its working medium contaminated, and the perishable ball of some working medium, accelerate its wearing and tearing.
The air ring type vacuum pump of the mid-bearings means of fixation of using in the industries such as biogas, steam simultaneously adopts individual layer design of Sealing Structure mode usually between its pump housing and mid-bearing.Usually adopt by the sealing of individual layer oil seal structure device between the pump housing and mid-bearing, the working medium that enters in the cavity easily sees through, and enters bearing, and accelerates bearing wear, shortens its working life, reduces quality of product.
Summary of the invention
The utility model provides a kind of for the problem of prior art and can effectively guarantee its sealing and Security and make it not be subject to the mid-sealing structure unit of the pump housing that working medium pollutes.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
The mid-sealing structure unit of a kind of pump housing, include the pump housing, impeller, motor and rotor shaft, described impeller is installed in the pump housing, described motor is connected with the pump housing and by the rotor shaft drives impeller, described impeller set is located at rotor shaft, is provided with bearing and one deck seal arrangement at least in the described pump housing, and described bearing is embedded in the pump housing, described seal arrangement is arranged between bearing and the impeller, and bearing and seal arrangement are socketed with rotor shaft respectively.
Wherein, be provided with two-layer seal arrangement between described bearing and the impeller.
Wherein, described bearing one end is provided with bearing plate, and bearing plate is connected with the pump housing by screw.
Wherein, described impeller one end is provided with the impeller pressing plate, and the impeller pressing plate is connected with impeller by hex screw.
Wherein, be provided with slider between the described two-layer seal arrangement.
Wherein, described rotor shaft is multidiameter shaft.
As preferably, described seal arrangement is oil sealing.
The beneficial effects of the utility model:
The utility model provides a kind of pump housing mid-sealing structure unit, bearing is arranged in the pump housing, and the double sealing structure mode is set in the pump housing to be sealed, when water vapor, biogas or other working medium enter in the pump housing, because the double sealing structure effect is isolated water vapor, biogas or other working medium in its pump housing fully with bearing or motor, make it be difficult for entering in the bearing, and the damage bearing, thereby guarantee its precision; Because design bearing in the pump housing, makes it be not easy to be polluted by water vapor, biogas or other working medium.The product vitals is difficult for being corroded, and its life-span is guaranteed, and its precision is not fragile.

Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the utility model is further described, the content that mode of execution is mentioned not is to restriction of the present utility model.Referring to Fig. 1 and Fig. 2, below in conjunction with accompanying drawing the utility model is described in detail.
The mid-sealing structure unit of a kind of pump housing as shown in Figure 1, include the pump housing 1, impeller 2, motor 3 and rotor shaft 4, described impeller 2 is installed in the pump housing 1 inner chamber, described motor 3 is connected with the pump housing 1 and by rotor shaft 4 drives impeller 2, described impeller 2 is sheathed on rotor shaft 4, be provided with bearing 5 and one deck seal arrangement 6 at least in the described pump housing 1, described bearing 5 is embedded in the pump housing 1, described seal arrangement 6 is arranged between bearing 5 and the impeller 2, and bearing 5 and seal arrangement 6 are socketed with rotor shaft 4 respectively.
During 2 work of motor 3 impeller, water vapor, biogas or other working medium can enter in the pump housing 1, because the seal action of Multilayer sealing device 6, water vapor, biogas or other working medium in its pump housing 1 are isolated with bearing 5 or motor 3 fully, make it be difficult for entering in the bearing 5, and damage bearing 5, thereby guarantee its precision, because bearing 5 designs in the pump housing 1, make it be not easy to be polluted by water vapor, biogas or other working medium again.
As preferably, be provided with two-layer seal arrangement 6 between described bearing 5 and the impeller 2.Two-layer seal arrangement 6 is set, can play multi-sealed effect, effectively isolated medium enters in the situation in the motor, can effectively save production cost.
