Component 430, first cleaning assembly 420 is used to clean the main suction nozzle 111, and second cleaning assembly 430 is used to clean
The branch suction nozzle 112.
As shown in Fig. 2 first cleaning assembly 420 and second cleaning assembly 430 are straight with the discharging tube 200
Lead in succession, the connectivity part and second cleaning assembly 430 of first cleaning assembly 420 and the discharging tube 200 with it is described
The connectivity part of discharging tube 200 is equipped with switching device, and the switching device is electrically connected with the control system 300, in order to control
The regulating switch device according to actual needs of system processed 300, make liquid outlet 120 to go out liquid only individually right through the first cleaning assembly 420
Main suction nozzle 111 is cleaned, or the liquid that of liquid outlet 120 is only individually carried out to branch suction nozzle 112 through the second cleaning assembly 430
Cleaning, or make liquid outlet 120 go out liquid through the first cleaning assembly 420 and the second cleaning assembly 430 simultaneously to the He of main suction nozzle 111
Branch suction nozzle 112 is cleaned.
First cleaning assembly 420 is helical form and is set around the main suction nozzle 111.
Preferably, in the embodiment of the present invention, first cleaning assembly 420 includes being arranged in the main suction nozzle 111
First jet 421；Second cleaning assembly 430 includes the second nozzle 431 being arranged in the branch suction nozzle 112.
Above-mentioned second cleaning assembly 430 also includes some branch pipes 432, and the second nozzle 431 of the mouth of pipe of some branch pipes 432 is inserted
If entering in the Heavenly Stems and Earthly Branches suction nozzle 112.
It is understood that the first jet 421 and the second nozzle 431 may be configured as 360 degree of jet roses,
So as to realize the high-pressure medium of the conveying of dredge pump 1 by first of installation on the first cleaning assembly 420 and the second cleaning assembly 430
Nozzle 421 and second nozzle 431 carry out thoroughly flushing without dead angle and clear to the main suction nozzle 111 and branch suction nozzle 112 of dredge pump 1
Reason.
Preferably, in the embodiment of the present invention, some 3rd nozzles 422 are provided with first cleaning assembly 420, for example
4,5 or 6 etc..Some 3rd nozzles 422 uniformly can be arranged on first cleaning assembly 420, when by the
When one cleaning assembly 420 is rinsed and clears up to the main suction nozzle 111 of dredge pump 1, while realizing to cesspool bottom and main suction
First 111 debris that position deposits farther out enter horizontal high voltage and wash away, and deposition debris is stirred, it is easier to be taken away by dredge pump 1.
Preferably, in the embodiment of the present invention, cutter 1111 and cutting screen pack are installed in the main suction nozzle 111
1112。
It is understood that above-mentioned cutter 1111 are connected by axle 900 with the motor 500, the cutter 1111
It is fixedly mounted on the bottom surface of the axle 900 by screw, the top of the axle 900 is defeated with the motor 500 by shaft coupling 910
Shaft is connected.
In the embodiment of the present invention, by the cutter 1111 and the cutting screen pack that are installed in the main suction nozzle 111 of dredge pump 1
1112 cooperation, makes cutting of the dredge pump 1 to debris in sewage more thorough, more abundant, prevents larger debris from winding impeller, blocks up
The plug main suction nozzle 111 of dredge pump 1, influences the normal operation of pump, wastes electric energy.
Preferably, in the embodiment of the present invention, the cutter 1111 are inducer, when being prevented from the operating of cutter 1111
The influence nominal situation of dredge pump 1.
It is to be appreciated that the features such as inducer is with its cascade solidity high and low incidence so that liquid working substance streams leaf
During piece type face pressure drop less, its maximum pressure drop point from vane inlet farther out, Fluid pressure blade outer edge area higher, institute
It is smaller with critical effective cavitation surplus of inducer；Meanwhile, inducer is a kind of aial flow impeller, and circulation area is big, even if
Also can normally be worked under the conditions of local cavitation and be not easily blocked, and centrifugal force is smaller, will not produce gas-liquid separation, thus lure
Guide wheel has anti-cavitation performance higher, and can improve the anti-cavitation performance of pump.
In sum, compared with prior art, the beneficial effect of dredge pump of the invention is：
(1), dredge pump of the invention receives the signal of pressure sensor using control system, automatically controls first switch dress
The closing with second switch device is put, the suction nozzle of dredge pump is backwashed by cleaning assembly, is cleared up, prevent debris from blocking
Blowdown pump suction causes dredge pump rotor oscillation, causes the possibility of mechanical destruction, the stability in use of pump in itself to dredge pump
It is good, increase the service life of pump；Extension maintenance and cleaning cycle, downtime are few, have saved cost of labor, the use of dredge pump
Low cost, usage cycles are long.
(2), further, dredge pump of the invention, if being additionally provided with Heavenly Stems and Earthly Branches suction nozzle, on the one hand realizes ten thousand in addition to main suction nozzle
After one has the main suction nozzle of foreign matters from being blocked, remain to maintain the normal work of dredge pump by branch suction nozzle；On the other hand when pending production,
When sanitary sewage duty ratio is larger, the main suction nozzle and the branch suction nozzle are simultaneously operable, and compact conformation operates steadily.
(3), further, dredge pump of the invention is by the cutter that are installed in the main suction nozzle of pump and cutting screen pack
Coordinate, debris larger in sewage are carried out with thorough, sufficient cutting, prevent foreign matter from winding increase motor on the impeller vanes and bear
Carry, be effectively reduced power consumption.
