Abstract
The utility model relates to a super low noise pump comprising a pump body, an impeller, a water-cooled electric machine, a water inlet and a water outlet body. The utility model is characterized in that the water-cooled electric machine is positioned at the upper part of the impeller in the pump body; a path formed by a gap is arranged between the water-cooled electric machine and the pump body, the connection position between the pump body and a water inlet body is provided with an O-shaped ring. The rotor of the water-cooled electric machine is connected with the enclosure of the water-cooled electric machine by a sliding bearing. The utility model has the following advantages that the noise of the pump is reduced by 5-10 dBA again, simultaneously the pump efficiency is improved by 2-3%, and the pump does not leak.
Description
Technical field
The utility model relates to a kind of pump, particularly a kind of ultra-low noise pump.
Background technique
Present existing Low noise pump mainly by the pump housing, impeller, mechanical seal, cool back water pipe, pump cover, water-cooled machine, rolling bearing etc. and form.There is following shortcoming in it: the flow of water pump that cooled back the water pipe backwater effect, thus having influenced the hydraulic efficiency of water pump, the motive sealing of machinery damages and leaks easily, and the noise that produces during the rolling bearing running is bigger.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of Low noise pump in the prior art, and a kind of noise that can further reduce water pump is provided; Improve pump efficiency; Make the leak free ultra-low noise pump of pump.The utility model designs a kind of ultra-low noise pump, comprise the pump housing, impeller, water-cooled machine, water intake, water-outlet body, it is characterized in that: water-cooled machine is arranged in the upper impeller of the pump housing, and the passage that has the space to constitute between the water-cooled machine and the pump housing has O shape circle in the joint of the pump housing and water inlet body.The rotor of water-cooled machine is connected the shell of water-cooled machine by sliding bearing.The utility model has the advantages that 5～10dBA falls in noise again that make pump, improve pump efficiency 2～3% simultaneously and make pump not have leakage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise the pump housing 1, impeller 2, water-cooled machine 3, water intake 4, water-outlet body 5 among the figure, it is characterized in that: water-cooled machine 3 is arranged in impeller 2 tops of the pump housing 1, the passage 6 that has the space to constitute between the water-cooled machine 3 and the pump housing 1 has O shape circle 7 in the joint of the pump housing 1 and water inlet body 4.The rotor 8 of water-cooled machine 3 is connected the shell of water-cooled machine 3 by sliding bearing 9.Main improvement of the present utility model is exactly on existing Low noise pump basis, and mechanical dynamic seal is removed, and changes O shape into and encloses 7 static seals, changes rolling bearing into sliding bearing 9 structures, makes the flow channels of the cooling channel 6 of water-cooled machine 3 as pump.Because the water outlet of pump is through the cooling chamber passage 6 of water-cooled machine 3, so after the cooling motor, what loss of the flow of pump nobody is so improve 2～3% than existing Low noise pump efficient; Noise than rolling bearing is low in the running owing to sliding bearing 9; All noise sources are all shielded by water in the pump in addition, so 5～10dBA can fall in the noise of pump again; Simultaneously, change mechanical seal into seal static seal, guaranteed that pump does not have leakage with O shape circle 7.
Claims (2)
1, a kind of ultra-low noise pump, comprise the pump housing, impeller, water-cooled machine, water intake, water-outlet body, it is characterized in that: water-cooled machine is arranged in the upper impeller of the pump housing, and the passage that has the space to constitute between the water-cooled machine and the pump housing has O shape circle in the joint of the pump housing and water inlet body.
2, by the described a kind of ultra-low noise pump of claim 1, it is characterized in that: the rotor of water-cooled machine is connected the shell of water-cooled machine by sliding bearing.
