Description

A kind of engine cooling water pump
Technical field
The utility model relates to a kind of engine cooling water pump, belongs to engine cooling water pump manufacturing technology field.
Background technique
At present, the cooling waterpump that motor is used generally adopts whole stand-alone configuration; Mainly by cast cast housing (not being with arc spiral shape volute casing), shaft connecting bearing; The integrated type water seal, the cast iron impeller is formed, and the major defect of this form is that underfed, lift are lower, fragile; Mainly show the following aspects: 1. the shape of water pump vane blade generally adopts backward bent vane, because the too small difficult acquisition higher flows of blade exit established angle; 2. corrosion, cavitation erosion take place in water pump direct casting iron flake wheel easily, the dynamic balancing weak effect, and loss power is big, and efficient is lower; 3. no water outlet snail formula runner on the water pump shell; Directly impeller is inserted the engine cylinder-body water intake; Throw away the cooling liquid divergence expression through impeller; Energy loss is big, performance and efficient are low, and performance requirement 4. water pump packings that do not reach the motor of state's four dischargings generally adopt seal ring or planar sealing pad, and assembling is complicated, lost efficacy easily.
The model utility content
The utility model technical problem to be solved is, overcomes the shortcoming of existing technology, proposes a kind of engine cooling water pump, can effectively improve the lift and the flow of water pump, reduces the loss of energy and the assembly technology of equipment.
In order to solve above technical problem; The utility model provides a kind of engine cooling water pump; Comprise water pump shell, shaft connecting bearing, integrated type water seal, water pump vane, sealed cover and water receiving pipe, be provided with bearing hole and water seal hole in the said water pump shell, said water receiving pipe is installed in the water inlet of said water pump shell; Said shaft connecting bearing is installed in the bearing hole of water pump shell, and the integrated type water seal is passed in the water seal hole that bearing journal is installed in water pump body; Said water pump vane is installed on the axle journal of bearing, leaves the gap with the angular surface type of said water pump shell, and places the center region of said water pump shell runner; Said sealed cover is installed on the water pump shell in the said water pump vane outside, links to each other with the engine water inlet.
The technological scheme that the utility model further limits is: aforesaid engine cooling water pump, and said water pump vane is a half-opened impeller, blade shape is Gothic, can effectively improve the lift of water pump; And select for use the PPS engineering plastics as material, can prolong the working life of water pump, and not produce corrosion, cavitation erosion, and dynamic equilibrium state is good.
Aforesaid engine cooling water pump, symmetry offers pressure compensation opening on the said water pump vane plate, and balance is owing to the uneven axial force that produces of impeller cover both sides coolant pressure effectively.
Aforesaid engine cooling water pump; Said sealed cover adopts both sides to be bonded with the two way sealed structure of fluorine rubber, and a side and water pump shell are fitted, and play the effect of water-sealed pump inner chamber; Opposite side and engine cylinder-body are fitted, and play the effect of water-sealed pump assembly and motor connection part; The metal that contacts with cooling liquid applies rust-preventing film, can prevent the corrosion of cover plate bare metal.Because fluorine rubber sealing gasket and cover plate are combined as a whole, and have simplified assembly process, also be difficult for dislocation in the process of installation and use, can better guarantee sealing effect.
Further; Aforesaid engine cooling water pump; The pumping chamber of said water pump shell is the spirality volute casing, and is arranged on the water pump shell through forging type, to reduce the casting defect of engine cylinder-body; Purpose is will collect from the high speed cooling liquid that blade flows out with less hydraulic loss to guide water outlet into, thereby can guarantee that water pump has higher efficient, higher lift.
The beneficial effect of the utility model is: the utility model novel structure, and it is convenient to implement, and can effectively improve lift of pump and flow, and dynamic balancing is effective; Through the setting of blade wheel structure, make the power consumption penalty of pump little, efficient reaches raising, and can prolong the whole working life of pump greatly.

Embodiment
Embodiment 1
A kind of engine cooling water pump that present embodiment provides; Structure such as Fig. 1 mainly are made up of water pump shell 1, shaft connecting bearing 2, integrated type water seal 3, water pump vane 4, sealed cover 5, water receiving pipe 6 to shown in Figure 3, and water receiving pipe 6 is installed in the water inlet of water pump shell 1; Shaft connecting bearing 2 is installed in the bearing hole of water pump shell; Integrated type water seal 3 is passed in the water seal hole that bearing journal is installed in water pump body, and impeller 4 is installed on the axle journal of bearing, forms certain clearance with the inclined-plane of water pump shell; Be in spiral shell spiral type runner center region, the two way sealed cover plate that the two sides all is bonded with fluorine rubber is installed on the water pump shell.
Water pump vane adopts half-opened impeller, adopts the Gothic blade 8 of external diameter 90mm, can guarantee that enough flows can effectively improve the lift of water pump again.Material selection PPS engineering plastics can prolong the working life of water pump, and not produce corrosion, cavitation erosion, and dynamic equilibrium state are good; In addition, have six pressure compensation openings 9 axial force of producing owing to impeller cover both sides coolant pressure is uneven of balance effectively on the back shroud of impeller.
The pumping chamber of water pump shell 1 adopts spirality volute casing 7; And be casted on the water pump shell; To reduce the casting defect of engine cylinder-body; Purpose is will collect from the high speed cooling liquid that blade flows out with less hydraulic loss to guide water outlet into, thereby can guarantee that water pump has higher efficient, higher lift.
Water pump packing cover plate 5 adopts two way sealed; Both sides are bonded with high performance import fluorine rubber; One side and water pump shell are fitted; Play the effect of water-sealed pump inner chamber, opposite side and engine cylinder-body are fitted, and play the effect of water-sealed pump assembly and motor connection part; The metal that contacts with cooling liquid adopts Cr
