Abstract
The utility model provides a punching electric pump impeller, comprising a font cover plate, a back cover plate and blades. The impeller is characterized in that: mounting holes corresponding to the mounting location of each blade are opened in the front cover plate and the back cover plate; mounting feet corresponding to the mounting holes are arranged on the upper and the lower ends of each blade, the blade is assembled between the front cover plate and the back cover plate; the mounting feet of the blade are inserted into the mounting holes corresponding to the front cover plate and the back cover plate. The mounting foot and the mounting hole are welded. In the utility model, the existing impeller casted integrally is divided into a plurality of parts which are manufactured by a punching method, and then is formed by welding formation, thus skillfully solving the problem that the width of the impeller output is narrow and is not easy to be casted.
Description
Technical field
The utility model belongs to the water pump accessory, a kind of specifically punching press impeller.
Background technique
The effect of water pump vane is that the mechanical energy of prime mover is directly passed to liquid, to increase the static energy and the kinetic energy (mainly increasing static energy) of liquid.Impeller generally has 6-12 sheet backward leaning vane.Impeller has three kinds of open type, half-closed and encloseds, and unshrouded impeller does not have cover plate in the blade both sides, make simple, clean conveniently, be applicable to and carry the material that contains relatively large suspended matter, efficient is lower, the fluid pressure of conveying is not high; Single shrouded wheel does not have cover plate in suction port one side, and at opposite side cover plate is arranged, and is applicable to that conveying easily precipitates or contain the material of particle, and efficient is also lower; Double shrouded wheel has front and rear cover plate at impeller in the blade both sides, and the efficient height is applicable to and carries clean liquid free from foreign meter.General centrifugal pump impeller mostly is this type of.
Impeller adopts the casting method manufacturing at present, because impeller outlet width is narrow partially, is difficult for casting, therefore causes the product mechanical strength not enough, causes yield rate lower.
The technological scheme of model utility
The purpose of this utility model provides a kind of punching press impeller of electrical pump, has changed the mode of traditional Foundry Production, adopts punch, the member welding forming, and structural strength improves.
The technical solution of the utility model is as follows:
A kind of punching press impeller of electrical pump, include forward and backward cover plate, blade, it is characterized in that: the mounting hole corresponding with each blade installation position arranged on the described forward and backward cover plate, each blade upper and lower end has the installation foot corresponding with mounting hole, blade is assemblied between the forward and backward cover plate, and the installation foot of blade is plugged in the mounting hole of forward and backward cover plate correspondence, uses between installation foot and the mounting hole to be welded to connect.
Described blade is an arc shaped blade.
The utility model advantage:
With former cast-in-block impeller, resolve into a plurality of parts and use process for stamping to make, adopt welding forming then, ingenious to have solved impeller outlet width narrow partially, is difficult for the problem of casting.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is a plan view of the present utility model.
Embodiment
Referring to Fig. 1-2.
A kind of punching press impeller of electrical pump, include front shroud 1, back shroud 2, the blade 3 of drawing, respectively go out 3 mounting holes 4 on the forward and backward cover plate 1,2, each blade 3 is forward and backward respectively 3 installation feet 5, and it matches with the mounting hole 4 of forward and backward cover plate, and blade 3 is assemblied between the forward and backward cover plate 1,2, the installation foot 5 of blade 3 is plugged in the mounting hole 4 of forward and backward cover plate 1,2 correspondences, and compress forward and backward cover plate 1,2 with pressing plate, and proofread and correct coaxality, weld between installation foot 5 and the mounting hole 4.
Claims (2)
