Abstract
The invention relates to an enclosed type impeller. The enclosed type impeller comprises a front cover which is of a circular disc shape, a rear cover corresponding to the front cover and a plurality of vanes; the center of the front cover is provided with a shaft hole, the center of the rear cover is provided with a circular opening, the vanes are arranged between the front cover and the rear cover, included angles a are arranged on the vanes, and the included angles a divide the vanes into first vanes and second vanes, the center lines of the top faces of the first vanes are collinear with the tangent line of the inner diameter of the shaft hole, and the first vanes are longer than the second vanes. The included angles a are additionally arranged on the vanes, so that the proportion constant of the water absorbing capacity and the water output capacity is achieved, and the constant current and the constant voltage of water discharging of a water pump are achieved; the vanes are oblique, so that the cutting effect of the vanes are increased, the water absorbing efficiency is improved, and the high lift and the high flow capacity of the water pump are achieved.
Description
Technical field
The present invention relates to impeller field, particularly relate to a kind of double shrouded wheel for water pump.
Background technique
Large discharge, high-lift and high efficiency pump all will be used in high-floor feedwater, high building fire-proof, petrochemical industry, petroleum pipeline conveying etc., the technical performance that traditional pump has is that flow and lift are inversely proportional to, namely when flow is large lift little or high-lift time flow little, and one of vitals determining pump performance is exactly impeller.Impeller is widely used in daily life and industrial production as the essential element of water pump etc., and for the size of different applicable situations and drainage capacity, impeller is designed to many different structures.
Summary of the invention
The object of this invention is to provide a kind of double shrouded wheel, realize the proportions constant of water absorption and water-outlet quantity.
The object of the invention is to be achieved through the following technical solutions:
A kind of double shrouded wheel, comprising:
A protecgulum, shape is disk, and the center of described protecgulum is provided with axis hole.
A bonnet, shape is corresponding with described protecgulum, and the center of described bonnet is provided with circular port, for water inlet.
Some blades, described blade is arranged between protecgulum and bonnet, described blade is provided with an angle a, and blade is divided into the first leaf and the second leaf by described angle a, the end face center line of described first leaf and the tangent line conllinear of shaft hole diameter, described first leaf is longer than the second leaf, the length being preferable over the first leaf is the twice of the second leaf length, makes the path of water suction be greater than the path of draining, realizes water suction space and is greater than drainage space, form negative pressure, thus realize draining.
Further, the outside of described bonnet is provided with the annular tongue matched with described circular port, is provided with adding of matching with described first leaf to come into leaves in described annular tongue, increases path and the water space capacity of water inlet, thus more water can be made to enter into impeller, increase soaking effect.
Further, the angle of described angle a is greater than 90 degree.
Further, the thickness of described blade is more and more thicker to the direction of protecgulum along bonnet, because protecgulum is power source, and the therefore junction surface of reinforced blade and protecgulum, thus the working life increasing impeller; Selectable, the sectional shape of described first leaf and the second leaf is parallelogram or rectangle, and when wheel blade is inclined between protecgulum and bonnet, the sectional shape of described first leaf and the second leaf is parallelogram, increase the shear effect of blade, thus increase soaking effect.
Further, the quantity of described wheel blade is 4 to 16, is preferably 9.
Further, the outside of described protecgulum is provided with the axle sleeve corresponding with described axis hole, increases the surface of contact of protecgulum and motor shaft, makes the connection of protecgulum and motor shaft more firm.
Further, the outside of described protecgulum is also provided with the annular sleeve around described axle sleeve, for the protection of axle sleeve, simultaneously for waterproof.
Beneficial effect of the present invention is: the present invention, by blade is added angle a, achieves the proportions constant of water absorption and water-outlet quantity, thus realizes the constant current constant voltage of pumping drainage; Blade is what tilt, thus adds the shear effect of big leaf's slice, increases water-taking efficiency, water pump can be made to reach high-lift and high flow capacity.
