Description

A kind of centrifugal pump of innovative blade
Technical field
This utility model is related to field of mechanical technique, and in particular to a kind of centrifugal pump of innovative blade.
Background technology
Centrifugal pump is a kind of application working machine widely, and it can be widely used for the row such as electric power, metallurgy, coal, building materials Industry conveys the slurry containing solid particle.Such as thermal power plant's hydraulic(-ash) sluicing, technics of metallurgy mineral dressing factory pulp conveying, coal washery coal slurry and dense medium Conveying etc..Either in commercial production is still lived, it all has irreplaceable status.
In recent years, country increasingly payes attention to energy-saving and emission-reduction.The energy saving research of centrifugal pump is increasingly paid attention to.For impeller effect The research of rate, all pays close attention to both at home and abroad the optimization of pump front and rear cover plate gap, the number of blade and impeller hydraulic performance substantially now;And for The anti scuffing research of impeller, is concentrated mainly on both at home and abroad cavitation corrosion, improves the aspects such as blade strength.
Used as the acting part of centrifugal pump, centrifugal pump does work impeller by the high speed rotation of impeller to liquid, so as to realize Conveying to liquid, is the vitals of centrifugal pump.Centrifugal pump impeller is generally divided into double shrouded wheel, half-opened impeller, open type leaf Three kinds of wheel.Double shrouded wheel efficiency is higher, most widely used, it is adaptable to cleaning liquid of the conveying without solid particle and fiber.It is half-open Formula impeller adiabatic efficiency is between double shrouded wheel and unshrouded impeller, it is adaptable to which conveying is easy to precipitate or the liquid containing solid suspension. And unshrouded impeller efficiency is minimum, but simple structure, it is processing, easy to manufacture, it is adaptable to which that conveying is containing more solid suspension or band The liquid of fiber, such as silt carrying flow.Three of the above impeller, no matter which kind of impeller blade cross sectional shape is substantially the same.Open type leaf Wheel is applied in some special occasions, but also faces in engineer applied problems, and such as efficiency is low, easy abrasion.Efficiency is low to be Determined by its version, the fluid into impeller can not be conveyed out completely, and segment fluid flow passes back into the pump housing;Its is defeated The dielectric property sent determines that impeller is easily abraded again, and the abrasion of unshrouded impeller is divided into physical abrasion and cavitation corrosion.
In the design of impeller, blade profile is generally rectangular cross-section, because front side of vane is plane, operation intermediary confrontation leaf The resistance of impeller blade is larger, and energy loss is higher;In operation the solid particle in medium is vertically hit in fortune with certain speed On capable blade, it is easier to cause physical abrasion.
