Detailed Description
In order to make the above features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Referring to fig. 1 to 4
The high-temperature high-speed pump with the self-cleaning function comprises a pump body 20 connected with a driving motor 10, wherein an impeller 30 connected with an output shaft 11 of the driving motor is arranged in a cavity 21 of the pump body, the impeller comprises a shaft sleeve 31, a plurality of inner impeller blades 32 are arranged at intervals on the periphery of the shaft sleeve, an annular partition bracket 33 with inner side surfaces fixedly connected with the outer side ends of the inner impeller blades is sleeved on the periphery of the shaft sleeve, a plurality of middle impeller blades 34 with spiral directions opposite to those of the inner impeller blades are arranged at intervals on the periphery of the annular partition bracket, and the pressure difference between the front and the back of the impeller of the pump cavity is kept to be zero, so that when the output shaft rotates, the inner impeller directly washes a sealing piece body through the inner wall of a sealing cavity, and because the spiral directions of the inner impeller blades are opposite to those of the middle impeller blades, flushing medium of an axial part is stressed and flows back, and the front part and the back of the impeller form high-speed circulating rotating liquid due to standing of scale is prevented from forming a block. A pumping high temperature medium vane wheel 35 is provided at the outer side of the middle impeller vane along the circumference of the hub so that pumping will be completed.
In this embodiment, the inner impeller blade and the middle impeller blade are arranged in a staggered manner, and the size ratio of the inner impeller blade to the middle impeller blade is 2:1, so that the pressure of the front part and the rear part (the sealing cavity 24) of the impeller is mainly kept constant. The middle vane blade is arranged at the hub spoke part of the pump impeller, and has certain rigidity so as to drive the pumping medium vane wheel to rotate, and the inner middle impeller is also arranged at the hub spoke part of the pump impeller.
In the embodiment, 3-5 inner impeller blades are arranged on the periphery of the shaft sleeve at intervals, and the optimal scheme is 4 inner impeller blades; and 3-5 middle impeller blades are arranged on the periphery of the annular partition support at intervals, and the best scheme is 4 middle impeller blades.
In this embodiment, the high temperature medium pumping impeller is a circumferentially swirling impeller 36 to pump the medium.
In this embodiment, a medium inlet 22 connected with the chamber is disposed at the lower part of the pump body, and a medium outlet 23 connected with the chamber is disposed on the water outlet pipe at the upper end of the pump body, so as to facilitate medium in and out, thereby completing pumping in cooperation with the impeller.
In this embodiment, the pump body is provided with a mounting hole for the output shaft of the driving motor to extend into the pump body cavity, the section between the mounting hole and the rear side of the impeller forms a sealing chamber 24, the output shaft extends into the cavity to be connected with the shaft sleeve of the impeller, and a mechanical sealing element 12 is further arranged between the rear side of the shaft sleeve of the impeller and the sealing chamber on the output shaft, so as to complete the sealing of the pump body.
The working principle of the impeller is as follows: the rotary liquid of middle blade directly washes the sealing member body through the sealing chamber inner wall when the output shaft rotates to because interior impeller is because blade spiral direction is opposite with middle blade, the flushing medium atress backward flow of axis part when the output shaft rotates, the impeller front portion forms the rotary liquid of high-speed circulation with the rear portion, guarantee that incrustation scale or fatlute can not form cubic because of standing, let the mechanical seal spare and the cavity of medium automatic clearance sealing chamber through forcing the pressurization circulation, and strengthen the cooling to sealing member sealing pair, produce scale deposit and the timely discharge of knot mud to easy high temperature simultaneously, make the pump normal operating greatly increased pump's life.
The foregoing is only illustrative of the preferred embodiments of the present invention, and includes the magnetically driven pump with no mechanical seal or the canned motor pump, so long as the pump and the seal cavity are suitable for cleaning, it will be apparent to those skilled in the art from this disclosure that it is not necessary to create or create any inventive work for designing the pump with self-cleaning function, but all equivalent changes, modifications, substitutions and variations made in accordance with the scope of the present invention without departing from the spirit and principles of the present invention.
