Abstract
The utility model provides a novel water pump. The water pump comprises a motor, a rotary shaft, a sleeve, at least two bearings, a case and an impeller, wherein the motor is connected with the rotary shaft by a transmission device; the sleeve is arranged outside the rotary shaft; the rotary shaft and the sleeve are connected by at least two bearings and at least two water seals; the impeller is arranged on the other end of the rotary shaft; the case which is connected with the sleeve is arranged outside the impeller; the rotary shaft is inserted to the case; a water inlet and a row of water holes are arranged on the case in a through manner; and the opening of the water inlet is downwards arranged on the sleeve on the right sides of the water seals. The gap between the impeller and the housing is 0.6mm to 1.0mm. The novel water pump can greatly relieve the pressure and the impact of water flow to the bearings, so that the service life of the bearings is increased.
Description
[technical field]
The utility model relates to a kind of novel water pump.
[background technique]
Water pump is the machinery of carrying liquid or making the liquid supercharging.It sends mechanical energy or other external energies of prime mover to liquid; Liquid energy is increased; Mainly be used for carrying liquid to comprise water, oil, acid & alkali liquid, emulsified liquid, suspended emulsion and liquid metal etc., the liquid that also can carry liquid, gaseous mixture and contain suspended solids.
The running principle of water pump: in water pump, fill water earlier, the impeller that starts the back rotation drives the water high speed rotating in the pump, and water is made centrifugal motion, outwards throws away and be pressed into outlet pipe; After water was thrown out of, near the pressure the impeller reduced, and near rotating shaft, just forms a low pressure area; The pressure here is more much lower than barometric pressure, and the water of outside just under atmospheric effect, is reopened the bottom valve intake pipe and got in the pump; The water of rushing in is thrown out of again in the impeller high speed rotating, and is pressed into outlet pipe; Impeller is continuous high speed rotating under power engine drives, and water just is pumped to eminence from lower continuously.The water intake of Centrifugal water pump commonly used is over against the rotating shaft of impeller, and water gets into the back from water intake and water seal and bearing caused bigger pressure and impact, fragile bearing.
[summary of the invention]
The technical problem that the utility model will solve is to provide a kind of novel water pump, can alleviate pressure and impact that bearing receives current greatly, increases the working life of bearing.
The utility model is achieved in that
A kind of novel water pump; Comprise a motor, a rotating shaft, a sleeve, at least two bearings, a housing and impellers, said motor connects said rotating shaft through a transmission device, and said jacket casing is located at outside the rotating shaft; Be connected with at least two water seals through said at least two bearings between said rotating shaft and the sleeve; Said impeller is located at the other end of rotating shaft, and the said impeller outside is provided with the housing that is connected with sleeve, and said rotating shaft is inserted in the housing; Logically on the said housing be provided with a water intake and a drain opening, the opening of said water intake is arranged on the sleeve on water seal right side down.
Further, the gap between said impeller and the housing is 0.6～1.0mm.
The advantage of the utility model is:
Gap between impeller and the housing is 0.6～1.0mm, when increasing the water pump pumping load, can avoid impacting each other between blade and the housing; In addition, water intake is positioned on the housing of rotating shaft side, and opening is arranged on the sleeve on water seal right side, can alleviate pressure and impact that bearing receives current greatly, increases the working life of bearing.
[description of drawings]
Combine embodiment that the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation of a kind of novel water pump of the utility model.
[embodiment]
See also shown in Figure 1; A kind of novel water pump that the utility model is related; Comprise a motor 1, a rotating shaft 2, a sleeve 3, at least two bearings 4, a housing 5 and impellers 6, said motor 1 connects said rotating shaft 2 through a transmission device 7, and said sleeve 3 is set in outside the rotating shaft 2; Be connected with 2 at least two water seals 8 through said at least two bearings between said rotating shaft 2 and the sleeve 3; Said impeller 6 is located at the other end of rotating shaft 2, and said impeller 6 outsides are provided with the housing 5 that is connected with sleeve 3, and said rotating shaft 2 is inserted in the housing 5; Logically on the said housing 5 be provided with a water intake 51 and a drain opening 52, the opening of said water intake 51 is arranged on the sleeve 3 on water seal 8 right sides down; The water intake 51 of the utility model is logical to be located on the housing 5 of rotating shaft 2 sides, and opening is arranged on the sleeve 3 on water seal 8 right sides, can alleviate pressure and impact that bearing 4 receives current greatly, increases the working life of bearing 4.Gap between said impeller 6 and the housing 5 is 0.6～1.0mm, and this design can be avoided impacting each other between blade and the housing when increasing the water pump pumping load.
Though more than described the embodiment of the utility model; But the technician who is familiar with the present technique field is to be understood that; We described concrete embodiment is illustrative; Rather than being used for qualification to the scope of the utility model, those of ordinary skill in the art are in the modification and the variation of the equivalence of doing according to the spirit of the utility model, all should be encompassed in the scope that the claim of the utility model protects.
