Description
Technical field
The utility model relates to a kind of rotary-vane vaccum pump more particularly to a kind of rotary-vane vaccum pump bottom plates and rotary vane type
Vacuum pump.
Background technique
Oil seal type direct connection sliding vane rotary vacuum pump is a kind of gas transport pump, it is a kind of gas to be made constantly to suck and discharge pump
Outside to reach the vacuum pump of pumping purpose, sliding vane rotary pump pump core is made of stator, rotor, blade and end cap etc..Rotor is mounted in fixed
The interior point of contact of sub- the inside, stator and rotor is tightly against producing eccentricity since the diameter of stator and rotor is different.
When vacuum pump operation, rotor high speed rotation in stator achievees the purpose that pumping.
Since bore of stator is off-centre operation, the center of gravity of pump core has offset, therefore when vacuum pump operates can generate unavoidably
Biggish vibration.By the way that the good design of vacuum pump, each position cooperates step by step, the vibration feelings of vacuum pump can be mitigated well
Condition.Excellent back-plane design produces effective damping noise reduction effect to vacuum pump.
The bottom plate of the prior art is usually four side structures.
This bottom plate bottom surface is smooth, easily because vibration generates displacement when vacuum pump operation；The mouth that four sides are constituted is hollow structure, no
Vacuum pump can be leaked and effectively be controlled, environment easy to pollute.
Utility model content
The purpose of the utility model is to provide a kind of rotary-vane vaccum pump bottom plate and rotary-vane vaccum pumps.
The purpose of this utility model is achieved through the following technical solutions：
The rotary-vane vaccum pump bottom plate of the utility model, the rectangular parallelepiped structure of bottom plate generally, the rectangular parallelepiped structure
The lower side portion of upper surface is divided into horizontal component, and the upper and lower part of upper surface is tilted down from horizontal component, upper surface middle part
It is provided with groove, lower surface central field portion position is groove floor, and rest part is equipped with reinforcing rib, four tops of the rectangular parallelepiped structure
Point part, which is equipped with, is fastenedly connected interface.
The upper surface of the rotary-vane vaccum pump of the utility model, the pump holder of the rotary-vane vaccum pump and above-mentioned bottom plate
Horizontal component connection, the interface that is fastenedly connected of four apex portions of the bottom plate are connect with ground.
Rotary vane type provided by the embodiment of the utility model is true it can be seen from above-mentioned technical solution provided by the utility model
Sky pump bottom plate and rotary-vane vaccum pump, floor structure is simple, light, good damping result, produce vacuum pump will not because of resonance
Raw offset, and it is convenient for safeguarding.

Specific embodiment
The utility model embodiment will be described in further detail below.Do not make in the utility model embodiment in detail
The content of description belongs to the prior art well known to professional and technical personnel in the field.
The rotary-vane vaccum pump bottom plate and rotary-vane vaccum pump of the utility model, preferable specific embodiment are：
The rectangular parallelepiped structure of bottom plate generally, the lower side portion of the upper surface of the rectangular parallelepiped structure are divided into horizontal component, on
The upper and lower part on surface is tilted down from horizontal component, and upper surface middle part is provided with groove, and lower surface central field portion position is recessed
Groove bottom, rest part are equipped with reinforcing rib, and four apex portions of the rectangular parallelepiped structure, which are equipped with, is fastenedly connected interface.
Bottom plate integrally uses the integral structure of precision aluminium-alloy cast form.
The horizontal component of the upper surface of the pump holder and bottom plate of rotary-vane vaccum pump connects, four apex of the bottom plate
The interface that is fastenedly connected divided is connect with ground.
The rotary-vane vaccum pump bottom plate and rotary-vane vaccum pump of the utility model carry out the improvement in structure to bottom plate,
Vibrationproof performance is improved, vacuum pump leakage is effectively controlled, makes vacuum pump vibrationproof performance more preferably.
Specific embodiment：
Rectangular parallelepiped structure generally, which keeps horizontal, to connect with pump holder
Position, appropriate offset can effectively adjust vacuum pump center of gravity；By-level part both ends with horizontal component is in a certain angle dips down
Tiltedly；
It is provided with groove among upper surface, convenient for collecting leakage pump oil, avoids environmental pollution.
Lower surface central field portion position is groove floor, and both ends are equipped with reinforcing rib, and groove, four tops are equipped among reinforcing rib
Point part, which is equipped with, to be fastenedly connected interface and connect with ground, is made using reduction and contact area of ground, the mode for increasing local pressure
Vacuum pump does not generate offset in the running；
Bottom plate integrally uses the integral structure of precision aluminium-alloy cast form, and structure is simple, highly effective.
The bottom plate of the utility model, structure is simple, light, good damping result, generate vacuum pump will not because of resonance inclined
It moves, and convenient for safeguarding.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
