Abstract
The utility model relates to the field of water pumps, and provides a water pump with good sealing performance. The water pump comprises a fixing seat, a bearing, a pump body, a sealing mechanism, an impeller and a rotating shaft. The fixing seat sleeves one end of the rotating shaft. The bearing is mounted at one end in the pump body after sleeving the rotating shaft. The rotating shaft is mounted in the pump body, and the impeller is mounted at the other end of the rotating shaft. The sealing mechanism is mounted at one end, close to the bearing, of the rotating shaft. A water inlet pipe is arranged on one side of the pump body, and a water outlet pipe is arranged on the other side of the pump body. Orifices of the water inlet pipe and the water outlet pipe are arranged outside the sealing mechanism respectively. The sealing mechanism is arranged on the bearing in the pump body, and certain gaps are formed among the fixing seat, the pump body and the impeller respectively, so that water leakage between the pump body and the fixing seat is prevented; the water pump has the advantages of simple structure, stable performance and long service life.
Description
Technical field
The utility model relates to a kind of water pump, relates in particular to the good water pump of a kind of sealability.
Background technique
Auto pump is the core component of car engine cooling system, its maintainability directly has influence on the normal work of motor, under normal circumstances, the failure mode of auto pump is Seepage, be that cooling water overflows from spillway hole by mechanical seal, if Leckage is more, illustrate that water pump lost efficacy, if now maintenance or replacing not in time, the water of seepage will penetrate into shaft connecting bearing inside gradually, corrode the rolling element of bearing, and the even more serious consequence that finally causes motor to damage, so it is particularly important that the reliability of mechanical seal seems in auto pump.
Model utility content
The technical problems to be solved in the utility model is, for the deficiencies in the prior art, and provides a kind of sealability good water pump.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of sealability good water pump, comprise fixed base, bearing, the pump housing, sealing mechanism, impeller and rotating shaft, described fixed seating is loaded on one end of described rotating shaft, described bearing housing is installed on the one end in the described pump housing after being loaded in described rotating shaft, described rotating shaft is installed in the described pump housing, its the other end is provided with described impeller, described rotating shaft is provided with described sealing mechanism near one end of described bearing, in one side of the described pump housing, be provided with intake pipe, opposite side is provided with outlet pipe, the mouth of pipe of described intake pipe and the mouth of pipe of described outlet pipe be all arranged at described sealing mechanism outside.
The utility model further preferred version is: between the described pump housing and described bearing, be provided with two seal rings.
The utility model further preferred version is: on described fixed base, prolong outer wall and be evenly provided with multiple mounting holes.
Implement the technical solution of the utility model, there is following beneficial effect: the utility model arranges sealing mechanism by holding at pump body inner shaft, and all has certain space between fixed base, the pump housing and impeller, and anti-sealing leaks between the pump housing and fixed base; The advantage that the utlity model has simple in structure, stable performance and grow working life.
