Abstract
The utility model relates to a cooling water pump impeller for a sedan engine. The cooling water pump impeller for the sedan engine comprises an impeller seat 1 and blades 2, wherein each blade 2 is an arc blade with the radius R of 51mm, and the seven blades 2 are uniformly distributed on the impeller seat 1; the centers of circles of the seven arc blades 2 are uniformly distributed on a concentric circle with the diameter D2 of 67.5mm, and the impeller has the inlet diameter D1 of 45.0mm, the outlet diameter D of 60mm, the inlet installing angle of 30 degrees and the outlet installing angle of 40 degrees; each blade has the inlet height b2 of 15mm and the outlet height b1 of 14mm, so that the flux is improved, and the reasonable optimal allocation of head and flux is ultimately realized. With the design, more liquids are involved in energy conversion in the flow process, and the flow is 200L / minute and the head is more than 0.9ba when the rotating speed is 5800 rpm / min; and the liquid flows smoothly at an inlet, so that the eddy current can be effectively avoided. Compared with the prior art, the cooing water pump impeller for the sedan engine has characteristics of compact structure, smooth liquid flow, high hydraulic efficiency and the like.
Description
Technical field
The utility model relates to a kind of centrifugal cooling waterpump of car that is used for, particularly a kind of motorcar engine cooling waterpump impeller.
Background technique
The motorcar engine cooling waterpump is because the narrow limitation of its installing space; And running temperature environment requirement; And consider manufacture cost; Its water pump vane all compares succinctly, generally all adopts the plastic impeller of injection molded, connects into water pump complement with assemblings such as volute, shaft connecting bearing, mechanical type water seal, land in the motor.During work,, drive liquid in rotation through rotatablely moving of impeller; Be transformed into mechanical energy in the liquid, the motion state of liquid is changed, accomplish the conversion of energy; To engine cooling the cooling liquid of certain flow and lift is provided, to satisfy the work working condition requirement of motor.Existing motorcar engine cooling waterpump impeller exists mostly that complex design, structure are not compact, working efficiency is not high.
Summary of the invention
The purpose of the utility model is the above-mentioned deficiency that overcomes existing technology, and the motorcar engine cooling waterpump impeller of a kind of simplicity of design, compact structure, high working efficiency is provided, and works in the operating temperature range of the best to guarantee motor car engine.
The technological scheme of the utility model is: a kind of motorcar engine cooling waterpump impeller; Comprise impeller base and blade; Blade is that radius is the curved blade of 50-51mm, and seven blades evenly distribute on the impeller base, and the even distribution diameter in the center of circle of seven curved blades is on the concentric circle of 67.0-67.5mm.
The further technological scheme of the utility model is: the inlet diameter D of impeller
1Be 44.0-45.0mm, outlet diameter D is 60mm.
The further again technological scheme of the utility model is: the import laying angle of impeller is 30 °, and the outlet laying angle is 40 °.
The utility model technological scheme further is: the entrance height b of blade
2Be 15mm, go out open height b
1Be 14mm.
The utility model has more liquid to participate in transformation of energy in flow process owing to adopt as above design, reaches when 5800 rev/mins of rotating speeds; Flow 200L/ minute; Lift＞0.9ba, and the ingress flow is steady, can effectively avoid the generation of eddy current; Compared with prior art, have characteristics such as compact structure, flow of fluid are smooth and easy, hydraulic efficiency height.
Further describe below in conjunction with accompanying drawing and embodiment detailed structure the utility model.
