Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
Shown in accompanying drawing 1,2, the utility model is a kind of water pump cover of new structure, comprise water pump drive pulley 1, water pump bearing 2, pump head housing 3, water pump seal 4, water pump vane 5, water pump cover 7, described water pump cover 7 are set to the structure that becomes one with cylinder body body 8, described pump intake 10 and pump outlet 11 are set to the structure with the cylinder body casting processing, and described water pump cover 7 is connected with pump head housing 3.
Be connected by clamping bolt 9 between described water pump cover 7 and the pump head housing 3, be cast with sealed adhesive slot 14 on the described water pump cover 7, scribble the water pump packing glue 6 in gap between water-sealed pump housing 7 and the pump head housing 3 in the sealed adhesive slot 14.
On described water pump cover 7 and the water pump cover flanged surface 13 that pump head housing 3 is connected bolt hole 12 is set, water pump cover 7 is fixedlyed connected with bolt hole 12 by clamping bolt 9 with pump head housing 3.
On described water pump cover 7 and the face that pump head housing 3 is connected 4 bolts hole 12 are set altogether; Be 4 through holes on the respective pump head capsule body 3, wherein less between two gaps has been water pump cover 7 and the bolt hole 12 of pump head housing 3 positioning actions.
The purpose of this utility model is achieved in that described water pump cover 7 is integrated on the engine cylinder-body body 8, and is as a whole with cylinder body body 8.Described integrated form water pump cover 7 is furnished with pump intake 10, pump outlet 11 and the bolt hole 12 of water pump pump head 3 is installed, and integrated form water pump cover flanged surface 13 is concordant with cylinder body body front-end face, is convenient to processing and assembling.
Integrated form water pump cover of the present utility model, the inner chamber molded lines is an involute-type, satisfies the current optimized design.Water flow section increases gradually according to the current requirement.Certain draft angle (being generally 3 degree) is reserved in withdrawing pattern requirement when considering the water cavity casting simultaneously.
