Description

A kind of high abrasion non-clogging impeller pump

Technical field

The utility model relates to a kind of wing pump, relates in particular to a kind of high abrasion non-clogging impeller pump.

Background technique

At present in industrial and agricultural production, urban construction, fields such as water conservancy are extensive use of all kinds of slurry pump, the slag stock pump, the blast pump, the pump series products of sewage pump or the like specific function, in actual use because the fluid solid content of suction is big, the grinding medium is many, overcurrent speed causes flow passage part (mainly being impeller) wearing and tearing fast soon, although continuous progress along with materials science, the impeller pump case of such pump adopts the alloy material or the macromolecular material manufacturing of high-wear resistance more, but because the conventional construction feature of flow passage part, abominable working condition and make quick wearing and tearing inevitable, the therefore short deadly defect that is still such pump working life.

In addition, when the fiber that contains longer dimension in the fluid of suction, soft material, then being wrapped in through regular meeting and causing suction obstruction, effect to reduce, damage driving machine (motor) on the impeller blade, also is the problem that often occurs in the reality.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of and has simple in structure, long service life, can effectively resist wearing and tearing, prevents to stop up the high abrasion non-clogging impeller pump of advantages such as generation.

For achieving the above object, the utility model adopts following technological scheme:

A kind of high abrasion non-clogging impeller pump, it comprises pump case, and pump case is provided with water intake and water outlet, is provided with impeller in pump case, impeller connects with driving machine, and described impeller is made up of blade and stator one-sided sealing, that three groups and the impeller plate, impeller shaft are connected as one at least.

Described blade is irregular rectangle, the angle that the radial line of it and the impeller plate rotates setting in the direction of the clock is distributed on the impeller plate, the upstream face of blade and top are respectively the plane of inclination angled with the impeller plate, and back side is vertical with the impeller plate or be cambered surface; The front end of blade (promptly axially near the water intake direction) is with shape, structure, the distribution of blade are basic identical but radial length is shorter than the stator of blade.

Described root of blade (promptly with the impeller shaft joining end) is that impeller outer is constant along locating width dimensions to the end, and axial dimension promptly highly proportionally amplifies, and stator then is that axial dimension is constant, and radial dimension amplifies.

Described pump case external diameter is circular, the top is that the pump case center is provided with water intake, water outlet is located at the tangent direction of pump case circumference, the pump case diameter is in proportion greater than impeller diameter, in pump case, be provided with and the proportional spin chamber of width of blade size, impeller in pump case with postposition with the joining propeller shaft couplings of driving machine.

The utility model has adopted the non-sheet impeller blade design design and the design of corresponding pump case of the uniqueness that is different from traditional product, this structural design features is: 1) with " swirling motion " the main means as energy that is sucked fluid and motion mode conversion, as shown in Figure 2, after fluid enters pump case by water intake, under the stator effect of high speed rotating, major part promptly joins the high speed rotating stream in the spin chamber, and flow out by water outlet, have only segment fluid flow after being quickened once more, to add rotating flow again by primary blades, like this, the fluid that is sucked then major part does not contact the process that is sucked of promptly having finished with primary blades, its result is exactly, under same operating mode and abrasive conditions, under the prerequisite of not obvious reduction working efficiency, can effectively slow down the rate of wear of impeller (blade), significantly prolonged its working life; 2) blade and stator have all been done thickening, have been avoided the cavitation wear design, so even inevitably wearing and tearing take place, this structure can guarantee that effective work area (length and width of blade) of impeller (blade) can rapid change not take place because of wearing and tearing, sudden inefficacy also can not occur, this has just guaranteed the working stability and the reliability of pump integral body; 3) stator has two effects before the impeller: the one, and to the fluid that sucks at a high speed accelerations of prewhirling, make its most of adding rotating flow and do not contact with blade, slow down impact and the wearing and tearing of axial force simultaneously to blade; The 2nd, play " disintegrator " effect, the big particle that sucks is carried out fragmentation and changes its moving direction, blade is played a protective role; When 4) containing the fibrous material (as weeds, strap, plastic rope etc.) of longer size in fluid, this structure can realize not having the continuous operation of obstruction; 5) simple in structure, easily manufactured, have good technology capability.

The utility model is wear-resistant because of its unique design has, long service life, nothing are stopped up, do not have the good characteristic that twines, can be widely used in manufacturing and designing of specific pump classes such as all kinds of sewage pumps, slurry pump, slag stock pump, blast pump, market prospects are wide, and economic benefit and social benefit are inestimable.
