Description

Vacuum pump

Technical field

The utility model relates to pump technical fields, refer in particular to a kind of vacuum pump.

Background technique

Existing vacuum pump, general volume is all smaller, and mounting structure is compact, when vacuum pump work, can generate big Calorimetric amount, so heat is not easy to be discharged, is accumulated in shell due to small in size, and the time is long, will make internal component It is impacted, reduce service life.

Therefore, the defect based on above-mentioned existing vacuum pump needs to improve existing vacuum pump.

Utility model content

The purpose of this utility model is that providing a kind of vacuum pump in view of the deficiencies of the prior art, which solves existing Present in some vacuum pumps: not the defects of easy heat radiation, influence service life.

To achieve the above object, the utility model is achieved through the following technical solutions: vacuum pump, including motor, pump Body, motor are installed on one end of the pump housing, and fixed case is equipped between the pump housing and motor, is equipped with fan, fan in the shaft of motor In fixed case.

Specifically, the fan includes outer ring, inner ring, blade, outer ring, inner ring are shifted to install, one end of blade and outer The medial surface connection of ring, the lateral surface of the other end and inner ring connect.

More specifically, the upper and lower end of the pump housing has each extended over cover board, is equipped with side between the side of two cover boards Plate, the outer end face of two cover boards are equipped with end cap, and cover board, side plate, end cap surround fixed case, and the shaft of motor is passed through from end cap.

Further, the cover board of the lower end of the pump housing offers ventilation hole.

Further, the side of the end cap has inner groovy, and vent passages are formed between inner groovy and side plate.

The utility model has the beneficial effects that: vacuum pump can be made more quickly by the way that fan is arranged in fixed case Heat dissipation, to prolong the service life.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the schematic diagram for removing side plate of the utility model.

Fig. 3 is the schematic diagram for removing cover board and end cap of the utility model.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

Seeing Fig. 1 --- Fig. 3, the utility model vacuum pump include: motor 1, the pump housing, and motor 1 is installed on one end of the pump housing, pump The upper and lower end of body is extended with cover board 3 to 1 side of motor respectively, and side plate 4, two cover boards 3 are equipped between the side of two cover boards 3 Outer end face end cap 2 is installed, the outer end face of cover board 3 is furnished with positioning pin, and the inner face of end cap 2 has location hole, and positioning pin is inserted Enter location hole, the shaft of motor 1 is passed through from end cap 2.

Pump housing one end of the utility model is extended with crossbeam 5 to 1 side of motor, and crossbeam 5 can support side plate 4.

The outer end face of the crossbeam 5 of the utility model offers screw hole, and correspondence offers hole on end cap 2, will by bolt End cap 2 and crossbeam 5 are fixed.

Fan 6 is installed, fan 6 includes outer ring 8, inner ring 9, blade 10, outer ring in the shaft of the motor 1 of the utility model 8, inner ring 9 shifts to install, and one end of blade 10 connect with the medial surface of outer ring 8, the lateral surface of the other end and inner ring 9 connects.

The side of the end cap 2 of the utility model has inner groovy 11, when end cap 2 and side plate 4 assemble, inner groovy 11 and side plate Vent passages are formed between 4.

The cover board 3 of the lower end of the pump housing of the utility model offers ventilation hole 7, when ventilation hole 7 assembles under fan 6 End, can divulge information.

In addition, pumping intracorporal rotor shaft oil sealing with there are two, increase the leakproofness of product, it will not permeability.

The utility model can be when motor 1 works, while rotates fan 6, does not need external power supply, and can make to pump Intracorporal hot-air is quickly pulled away, and is realized rapid cooling, is extended the service life of vacuum pump.

Certainly, the embodiment of the above, only the preferred embodiments of the utility model, not limit the utility model Practical range, therefore all equivalence changes done according to structure, feature and principle described in present utility model application the scope of the patents or repair Decorations, should be included in present utility model application the scope of the patents.
