Abstract

The utility model discloses an internal-combustion engine cooling water pump adopting flexible blades. The cooling water pump comprises a pump body, an impeller positioned and mounted in the pump body through a pump shaft, as well as a water inlet pipe and a water outlet pipe which are integrated with the pump body, wherein the impeller comprises an impeller hub and impeller blades arranged on the impeller hub; and the impeller blades adopt flexible blades with the Shore A hardness 70-75. Therefore, when the impeller works, gapless operation between the impeller and the pump body is achieved by virtue of the flexible deformation of the flexible blades, so that not only is the volume efficiency of the water pump improved, but also the self-suction function of the water pump is enhanced. Accordingly, the utility model has the advantages of more compact structure, smaller volume and lighter weight.

Description

A kind of cooling water of internal combustion engine pump that adopts flexible blade

Technical field

The utility model relates to a kind of cooling water of internal combustion engine pump, and especially a kind of impeller adopts the cooling water of internal combustion engine pump of flexible blade.

Background technique

At present, water pump vane commonly used, what generally adopt is rigid blade, therefore, during impeller work, such water pump must leave the gap between its blade and the pump housing, so, the volumetric efficiency of water pump is not high, and water pump self-suction is limited in one's ability, simultaneously, the structure of this type water pump is compact inadequately, and volume, weight are all bigger.

The model utility content

The utility model provides a kind of cooling water of internal combustion engine pump that adopts flexible blade at the deficiencies in the prior art, and its impeller blade is set to flexible blade, when then impeller is worked, by the resiliently deformable of this flexible blade, realized and the pump housing between the running of no gap, therefore, not only improved the volumetric efficiency of water pump, also increased the self-absorption function of water pump, in addition, also made the utility model structure more compact, volume is littler, and weight is lighter.

For realizing above technical purpose, the utility model will be taked following technological scheme:

A kind of cooling water of internal combustion engine pump that adopts flexible blade, comprise the pump housing, by the impeller of pump shaft location and installation in the pump housing and intake pipe and the outlet pipe that is wholely set with the pump housing respectively, described impeller comprises impeller hub and is arranged at impeller blade on this impeller hub, and described impeller blade is the shore a hardness value between 70~75 flexible blade.

Described impeller is connected by the mode that spline endoporus-splined shaft is connected with pump shaft, and described impeller endoporus is a splined hole, and pump shaft cooperates the installation position to be set to splined shaft with impeller.

Described impeller endoporus is 12 tooth serration spline endoporus.

The end face periphery of described intake pipe and outlet pipe is wholely set the locking anticreep muscle that arc length is 0.7~0.8 π r all respectively, and the arc two ends of this arc locking anticreep muscle are tangent with corresponding intake pipe or outlet pipe external diameter respectively, wherein, r is the radius of locking anticreep muscle.

The arc length of described locking anticreep muscle is 0.76 π r.

According to above technological scheme, can realize following beneficial effect:

1, because impeller described in the utility model adopts flexible blade, when then impeller is worked, by the resiliently deformable of this flexible blade, realized and the pump housing between the running of no gap, therefore, not only improved the volumetric efficiency of water pump, also increased the self-absorption function of water pump, in addition, also made the utility model structure more compact, volume is littler, and weight is lighter.

2, pump shaft described in the utility model is connected by the mode that spline endoporus-splined shaft is connected with impeller, when then impeller is worked, can be poor according to its pressure at both sides, automatically be in axial sliding along pump shaft, and be positioned to pressure balance point (working position of impeller the best), so both carry moment of torsion, improved the Performance And Reliability of water pump again.

3, it is π r that the utility model has been wholely set arc length all respectively in the end face periphery of intake pipe and outlet pipe, and the locking anticreep muscle that the two ends of arc are tangent with the water pipe external diameter respectively, wherein, r is the radius of locking anticreep muscle, therefore, when flexible pipe is connected with outlet pipe with intake pipe respectively, can guarantee effectively that on the one hand intake pipe is connected with flexible pipe assembling locking respectively with outlet pipe, on the other hand, the amount of deformation that causes in the time of can also reducing flexible pipe and intake pipe and outlet pipe assembling effectively, promptly avoided flexible pipe to be connected inefficacy with intake pipe or outlet pipe because of amount of deformation is excessive, be that the technical solution of the utility model can be so that intake pipe be when being connected with flexible pipe respectively with outlet pipe, more convenient, reliably.

Embodiment

Accompanying drawing discloses the structural representation of a preferred embodiment of the utility model without limitation, explains the technical solution of the utility model below with reference to accompanying drawing.

Shown in Fig. 1, Fig. 2 a, Fig. 2 b, Fig. 3 a and Fig. 3 b, the cooling water of internal combustion engine pump of employing flexible blade described in the utility model, comprise the pump housing 1, by the impeller 2 of pump shaft 5 location and installation in the pump housing 1 and intake pipe 4 and the outlet pipe 3 that is wholely set with the pump housing 1 respectively, described impeller 2 comprises impeller hub 22 and is arranged at impeller blade 21 on this impeller hub 22, and described impeller blade 21 is the shore a hardness value between 70~75 flexible blade.During production, with impeller hub 22 metal-cored and nitrile rubber and other materials through special formulation, by the mold integral injection-compression molding, promptly can be made into impeller 2 through subsequent treatment again, therefore, during impeller 2 rotation,, realized and the no gap running of 1 of the pump housing by the resiliently deformable of flexible rubber blade.

The utility model then is connected with impeller 2 described pump shaft 5 for improving the Performance And Reliability of water pump by the mode that spline endoporus-splined shaft is connected, described impeller endoporus 23 is a splined hole, and pump shaft 5 cooperates the installation position to be set to splined shaft with impeller 2.Described impeller endoporus 23 shown in Fig. 2 a is 12 tooth serration spline endoporus.Be pump shaft 5 with impeller 2 between to be connected be that 12 tooth serration splines are connected.
