Machine seals.Drive mechanism drives pump shaft, impeller to rotate, and impeller rotates the centrifugal force produced and entered from the pump housing by medium
Mouth passage sucks discharges from exit passageway, it is achieved pump medium.The impeller of existing dredge pump all uses
Arranging three spiral vanes in meeting the transverse plane of pump housing intake channel, these three spiral vanes are with in impeller
The heart is that initial point gradually extends to impeller outer circumferential edges, and is uniformly distributed in impeller end plane, three spirals
Shape blade forms three independent spiral flow channels from the impeller center of circle to outer circumferential edges each other.It is main
Wanting shortcoming is that plug spiral flow channel between adjacent two blades of impeller easily gambled by the granule in medium and fiber
In, reduce operational efficiency, and when dallying, easy burn-out machine seals.
Summary of the invention
It is an object of the invention to the shortcoming existed for prior art, it is provided that a kind of impeller channel be difficult to gambling plug,
The new and effective dredge pump that operational efficiency is high.
Technical scheme includes the pump housing, impeller, pump shaft, front pump cover, and pump shaft one end connects driver
Structure, the other end is fixing with impeller to be connected, and is installed on the pump housing by axle sleeve in the middle part of pump shaft, and impeller is installed on pump
In pump chamber between body intake channel and exit passageway, pump spindle center line overlaps with pump housing intake channel centrage；
Mainly arranging two spiral vanes in wheel nose face, two spiral vanes are symmetrical before the impeller
Both sides, the end face center of circle, the inner of two spiral flow channels that two spiral vanes are formed each other interconnects mutually
Logical, the axial height of spiral vane is gradually lowered from inside to outside, and drive end bearing bracket inner face has and spiral type leaf
The involute circular arc camber that the axial height of sheet cooperates.
Preferably, the axial fit clearance between spiral vane and drive end bearing bracket inner face is 0.25 millimeter.
Preferably, the pump housing of axle sleeve periphery is provided with machine oil sealing chamber, machine oil sealing chamber by the pump housing, mechanical seal ring,
The annular seal space constituted between sealing gland, mechanical seal ring is fitted in sleeve outer circle face and the pump housing by sealing gland
And between sealing gland.
It is an advantage of the invention that impeller uses two spiral vanes, two spiral vanes are formed each other
Two spiral flow channels be interconnected, media particle and fiber are difficult to accumulated plugging runner in runner, right
With the dependable performance of pumping of granule or fiber medium, operational efficiency improves 5-10%.

Detailed description of the invention
New and effective dredge pump as shown in Figure 1, including the pump housing 2, impeller 3, pump shaft 5, front pump cover 1,
Pump shaft 5 one end connects drive mechanism, and the other end is fixing with impeller 3 to be connected, by axle sleeve 7 in the middle part of pump shaft 5
Being installed on the pump housing 2, impeller 3 is installed in the pump chamber between the pump housing 2 intake channel and exit passageway, pump
Axle 5 centrage overlaps with the pump housing 2 intake channel centrage；Two spiral type leaves are set in impeller 3 front end face
Sheet 12, described impeller 3 front end face, it is the impeller 3 end face in face of the pump housing 2 intake channel side, impeller
3 rear end faces install wheel hub 4, and two spiral vanes 12 are symmetrically distributed in both sides, the impeller 3 front end face center of circle,
Spiral angle on the most each diameter line and two spiral vane 12 joinings, height and from the center of circle away from
From equal, the starting point of two spiral vanes 12 is positioned on the diameter line of both sides, the center of circle, described spiral vane
The starting point of 12 is the end points near circle centre position, two spirals that two spiral vanes 12 are formed each other
