Description
Technical field
The utility model relates to vacuum pump technology field, specifically a kind of rotary-vane vaccum pump.
Background technique
Rotary-vane vaccum pump is a kind of oil seal type oil-sealed rotary pump, and operating pressure range is 101325 ~ 1.33 × 10-2
(Pa) belong to roughing pump.It can be used alone, and can also be used as the fore pump of other high-vacuum pumps or ultrahigh vacuum pump.It
It has been widely used in the production such as metallurgy, machinery, military project, electronics, chemical industry, light industry, petroleum and medicine and scientific research department.But it is existing
There is also some problems in practice for some rotary-vane vaccum pumps.
Utility model content
To solve the above-mentioned problems, the utility model discloses a kind of rotary-vane vaccum pumps.
The technical solution of the utility model are as follows: a kind of rotary-vane vaccum pump, including the pump housing, the pump housing is interior to be equipped with rotor, stator
And blade, stator are fixedly connected in the internal chamber wall of the pump housing, the surface pivots of stator are connected with rotor, and internal rotor is fixedly connected
There is blade, blade is tightly attached to the internal chamber wall of the pump housing by blade spring, and top is equipped with the air inlet being connected to pump housing inner cavity on the pump housing
Pipe and exhaust pipe, the pump housing are externally provided with cabinet, and there are reservoir between cabinet and the top of the pump housing, exhaust pipe and air inlet pipe are located at
The part of box house is located in reservoir, and coolant liquid is equipped in reservoir, is equipped between exhaust pipe and air inlet pipe and cabinet close
Seal.
Further, for blade using rotor center as dot, uniform genesis analysis is equipped with blade bullet on rotor in blade
Spring is covered with heat sink on the blade of blade spring rear portion.
Further, air inlet pipe one end is equipped with filter screen.
The usefulness of the utility model: the application changes previous in pump housing inner cavity or the knot of external setting radiator
Cooling mechanism is arranged between cabinet and the pump housing structure, i.e., around air inlet pipe and exhaust pipe, first carries out in air inlet with regard to energy rate cold
But, the overall weight (volume for reducing heat dissipation) of the pump housing can either effectively be reduced, moreover it is possible to improve cooling effect (in source
Cool down).

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of rotary-vane vaccum pump, including the pump housing 1, the pump housing 1 is interior to be equipped with rotor 3, stator 2 and blade 4, and stator 2 is fixed to be connected
It connects in the internal chamber wall of the pump housing 1, the surface pivots of stator 2 are connected with rotor 3, and blade 4, blade 4 are fixedly connected with inside rotor 3
The internal chamber wall of the pump housing 1 is tightly attached to by blade spring 5, top is equipped with the air inlet pipe 9 being connected to 1 inner cavity of the pump housing and row on the pump housing 1
Tracheae 8, the pump housing 1 are externally provided with cabinet 7, there are reservoir 10 between cabinet 7 and the top of the pump housing 1, exhaust pipe 8 and air inlet pipe 9
Part inside cabinet 7 is located in reservoir 10, and coolant liquid, exhaust pipe 8 and air inlet pipe 9 and cabinet are equipped in reservoir 10
Sealing ring 13 is equipped between 7,9 one end of air inlet pipe is equipped with filter screen.
For blade 4 using 3 center of rotor as dot, uniform genesis analysis is equipped with blade spring 5 on rotor 3 in blade 4, revolves
Heat sink 6 is covered on 5 rear portion blade 4 of flat spring.
Change previous in pump housing inner cavity or the structure of external setting radiator, cooling mechanism is arranged in cabinet and pump
Between body, i.e., around air inlet pipe and exhaust pipe, energy rate is first cooled down in air inlet, can either effectively reduce the whole of the pump housing
Body weight (volume for reducing heat dissipation), moreover it is possible to improve cooling effect (cooling down in source).
