Abstract
The utility model discloses a low-vibration and low-noise water pump structure. The water pump comprises a pump body, an impeller, a pump shaft (6) and a support (1), wherein the pump body adopts a double-volute pump body (4); the pump shaft (6) is sealed with the double-volute pump body (4) through a cartridge mechanical seal (3); and the pump shaft (6) is mounted on the support (1) through a bearing component (2) and connected with a motor spindle through a flexible connecting component (7). The low-vibration and low-noise water pump structure provided by the utility model has the advantages of long service life, low vibration and noise, simple structure and reliable performance.
Description
Technical field
The utility model relates to a kind of water pump structure, particularly relates to a kind of low low noise water pump structure that shakes.
Background technique
Referring to Fig. 3, the existing pump structure adopts pump and motor rigid joint, and the pump axial force is born by motor, and the cantilever of pump is longer, the amount of deflection of pump is bigger, and pump very easily produces vibration and noise, the single mechanical end face seal of pump shaft envelope, inconvenience is installed, and the machine envelope does not install sparge water additional, and machine envelope operational safety is low.The pump housing adopts single hull structure, and axial force and radial force can only be born by motor.
The model utility content
Technical problem to be solved in the utility model provides a kind of long service life, the low low noise water pump structure that shakes that vibration and noise is little.
In order to solve the problems of the technologies described above, the low low noise water pump structure that shakes that the utility model provides, comprise the pump housing, impeller, pump shaft and bearing, the described pump housing is the double volute pump body, described pump shaft is by integrated mechanical sealing and the sealing of described double volute pump body, described pump shaft is installed on the described bearing by bearing part, and described pump shaft connects with electric machine main shaft by the resilient connection parts.
Be connected with wash tub pipe between described integrated mechanical sealing and the described double volute pump body.
Described impeller is no equalizing orifice impeller.
Adopt the low low noise water pump structure that shakes of technique scheme, by the pump housing is changed into the design of double volute pump body by mono-hull, in order to most of radial force of ballast pump generation.By adopting integrated mechanical sealing that the fitting machine envelope is more prone to, make the operation of machine envelope more reliable by installing wash tub pipe increase sparge water additional to integrated mechanical sealing.Adopt bearing part to bear axial force, change pump into resilient connection by rigid joint, shortened the arm length of pump, improved the rigidity of pump shaft, avoided the leaf frequency and the frequency multiplication of pump.
The utlity model has following advantage:
1. employing integrated mechanical sealing is installed and removed very conveniently, and integrated mechanical sealing is installed additional sparge water, has improved the working life of mechanical seal.
2. adopt double-shell structure balance radial force, reduced the vibration of pump.
3. adopt bearing to bear axial force, make pump change resilient connection into, the pump cantilever is shortened, reduced the amount of deflection of pump, improved the rigidity of pump shaft, help reducing the vibration and noise of pump by rigid joint.
4. impeller balance hole is removed, blowback stream is reduced, help reducing the noise of pump.
In sum, the utility model is a kind of long service life, vibration and noise is little and the low low noise water pump structure that shakes simple in structure, reliable performance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural perspective;
Fig. 3 is the existing pump structural drawing.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, bearing 1 is connected on the double volute pump body 4, pump shaft 6 is by integrated mechanical sealing 3 and 4 sealings of double volute pump body, be connected with wash tub pipe 8 between integrated mechanical sealing 3 and the double volute pump body 4, pump shaft 6 is installed on the bearing 1 by bearing part 2, pump shaft 6 connects with electric machine main shaft by resilient connection parts 7, and pump shaft 6 is equipped with the no equalizing orifice impeller 5 that is in the pump shaft 6.
Referring to Fig. 1 and Fig. 2, by the pump housing is changed into 4 designs of double volute pump body by mono-hull, in order to most of radial force of ballast pump generation.By adopting integrated mechanical sealing 3 that the fitting machine envelope is more prone to, make the operation of machine envelope more reliable by installing wash tub pipe 8 increase sparge waters additional to integrated mechanical sealing 3.Adopt bearing part 2 to bear axial force, change pump shaft 6 and connecting of electric machine main shaft into resilient connection parts 7 resilient connection by rigid joint, shortened the arm length of pump, improved the rigidity of pump shaft 6, avoided the leaf frequency and the frequency multiplication of pump, changed impeller into no equalizing orifice impeller 5, equalizing orifice has been removed, blowback stream is reduced, help reducing the noise of pump.
