Abstract
The utility model discloses a kind of Roots pump of quiet close structure, described Roots pump motor is positioned at the top of Roots pump, described Roots pump end cap is positioned at the bottom of Roots pump rotor, described Roots pump body is positioned at the bottom of Roots pump end cap, described Roots pump protecgulum is positioned at the lower end of Roots's pump housing, described Roots pump motor core is arranged on Roots pump cover internal, and described roots pump rotor axle is connected with Roots pump rotor.The utility model is by being the same axis by Roots pump rotor and roots pump rotor axle, the Roots pump motor stator poured into a mould directly is assemblied in the bonnet of Roots pump, then accurate seal structure is also in by Roots pump end cap and Roots pump protecgulum, after being fully assembled, be in complete sealing state in Roots pump, all sealings are static seal, thus solve the fault of leakage of oil, leakage vacuum, greatly reduce maintenance cost, ensure that the cleaning of working environment.
Description
Technical field
The utility model relates to vacuum transmission field, is specially a kind of Roots pump of quiet close structure.
Background technique
The sealing of current domestic travel axis is all adopt the sealing of skeleton rubber shaft seal substantially; this sealing means; due to the characteristic of skeleton rubber shaft seal; the axle coordinated with it, hole dimension tolerance are variant, the lacking experience of assembly crewman, operating conditions change all frequently can there is leakage of oil, leak the fault of vacuum, thus cause the problem of shutdowns, stoppings production, pollution work-yard and increase labor intensity.
Summary of the invention
The technical problem that the utility model solves is the Roots pump providing a kind of quiet close structure, to solve the problem.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Roots pump of quiet close structure, comprise Roots pump rotor, Roots pump end cap, Roots's pump housing, Roots pump protecgulum, Roots pump motor stator, roots pump rotor axle, described Roots pump rotor is positioned at the top of Roots pump, described Roots pump end cap is positioned at the bottom of Roots pump rotor, described Roots pump body is positioned at the bottom of Roots pump end cap, described Roots pump protecgulum is positioned at the lower end of Roots's pump housing, described Roots pump motor stator is arranged on Roots pump cover internal, and described roots pump rotor axle is connected with Roots pump rotor.
As preferably, described Roots pump rotor and roots pump rotor axle are the same axis.
As preferably, the working principle of described Roots pump is decomposed by motor, and rotor mandrel uses pump rotor axle, and motor stator is directly fixed on the pump housing.
The utility model is by being the same axis by Roots pump rotor and roots pump rotor axle, the Roots pump motor stator poured into a mould directly is assemblied in the bonnet of Roots pump, then accurate seal structure is also in by Roots pump end cap and Roots pump protecgulum, after being fully assembled, be in complete sealing state in Roots pump, all sealings are static seal, thus solve the fault of leakage of oil, leakage vacuum, greatly reduce maintenance cost, ensure that the cleaning of working environment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view in the A-A cross section of Fig. 1.
Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1-2, a kind of Roots pump of quiet close structure, comprise Roots pump rotor 1, Roots pump end cap 2, Roots's pump housing 3, Roots pump protecgulum 4, Roots pump motor stator 5, roots pump rotor axle 6, described Roots pump rotor 1 is positioned at the top of Roots pump, described Roots pump end cap 2 is positioned at the bottom of Roots pump rotor 1, described Roots's pump housing 3 is positioned at the bottom of Roots pump end cap 2, described Roots pump protecgulum 4 is positioned at the lower end of Roots's pump housing 3, it is inner that described Roots pump motor stator 5 is arranged on Roots pump end cap 2, described roots pump rotor axle 6 is connected with Roots pump rotor 1.
As preferably, described Roots pump rotor 1 and roots pump rotor axle 6 are the same axis.
As preferably, the working principle of described Roots pump is decomposed by motor, and rotor 1 mandrel uses pump rotor axle 6, and motor stator is directly fixed on the pump housing.
The utility model is by being the same axis by Roots pump rotor and roots pump rotor axle, the Roots pump motor stator poured into a mould directly is assemblied in the bonnet of Roots pump, then accurate seal structure is also in by Roots pump end cap and Roots pump protecgulum, after being fully assembled, be in complete sealing state in Roots pump, all sealings are static seal, thus solve the fault of leakage of oil, leakage vacuum, greatly reduce maintenance cost, ensure that the cleaning of working environment.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
