Abstract
The utility model relates to a centrifugal sand pump, which can effectively increase sand-pumping efficiency. The utility model the technical scheme that the utility model provides the centrifugal sand pump, the inside of a pump shell is provided with an impeller which is arranged on a pump shaft through an impeller connecting disk and the pump shell is connected with a front cover of the pump shell and a rear cover of the pump shell. The utility model is characterized in that the outer side of the impeller connecting disk is provided with gland filling cavities along the circumferential direction, and the inside of each gland filling cavity is provided with a Y-shaped sealing ring; the Y-shaped sealing ring is arranged between outer diameters of both sides of the impeller and the pump shell; the outer side of an imbibition port of the impeller is provided with cavities along the circumferential direction, and the Y-shaped sealing rings are arranged in the cavities. The utility model effectively solves gland sealing, the sealing between the outer side of the impeller and the inner side of the pump shell and the sealing of the imbibition port, therefore the sand-pumping efficiency is raised.
Description
Technical field: the utility model relates to a kind of centrifugal shell pump.
Background technique: because the working environment of sand pump is very abominable, pump case is inner and damage in impeller is very serious, and in a short period of time, pump case and impeller are subjected to heavy wear, excesssive gap, and the suction journey reduces lift and also reduces inefficiency.
Sand pump in the work, suction port are negative pressure, and outlet is a malleation.When outlet pressure raises, should not only not go out from sand and water that outlet is gone out, the effect that is subjected to not only outlet pressure and entrance negative pressure on the contrary the gap in the middle of impeller outer wall and pump case inwall down but also got back to suction port work shifts where laborers do not exerts themselves motor, and excessive fuel consumption is not worked.This should become inner loop from the Sha Heshui that outlet is gone out greatly with regard to equaling, and causes very big mechanical wear and idle work.
The negative pressure of suction port produces by the impeller rotating centrifugal, should suck the pump housing to sand under water by pipeline, raises out the pump housing by the impeller rotation again.After sand pump work a period of time, impeller and pump case, packing rope wearing clearance become big, at this moment a large amount of outlet sand is subjected to will pour in suction port under the work of outlet pressure and entrance negative pressure, sand and water circulate inner generation of pump case, will cause the negative pressure of suction port to reduce like this, the suction deficiency, produce to inhale husky less, go out husky also less, the consequence work shifts where laborers do not exerted themselves of motor, make and take out husky efficient and descend greatly.
The model utility content: the technical problems to be solved in the utility model provides the centrifugal shell pump that husky efficient is taken out in a kind of effective raising.Technological scheme: a kind of centrifugal shell pump, be provided with impeller in the pump case, impeller is contained on the pump shaft by the impeller land, pump case is connected to pump case protecgulum and pump case bonnet, it is characterized in that: in the impeller land outside, along the circumferential direction be provided with the packing filling chamber, in the packing filling chamber y-type seal ring be housed; Between the both sides of impeller external diameter and housing, y-type seal ring is housed; In the outside of suction eye, along the circumferential direction be provided with chamber, y-type seal ring is housed in the chamber.Beneficial effect:, therefore improved greatly and taken out husky efficient because the utility model structure has solved packing_seal effectively, the impeller outside seals with sealing, the suction port of inside pump casing.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment: as shown in the figure, be provided with impeller 5 in the pump case 1, impeller 5 is contained on the pump shaft 7 by impeller land 13, pump case is connected to pump case protecgulum 2 and pump case bonnet 6, in the impeller land outside, along the circumferential direction be provided with the packing filling chamber, y-type seal ring 3 is housed in the packing filling chamber; Between the both sides of impeller external diameter and housing, y-type seal ring is housed, during enforcement, is provided with the external diameter that round boss 14 constitutes impeller in the both sides of impeller, y-type seal ring 4, y-type seal ring 8 are housed between round boss and the housing; In the outside of suction eye, along the circumferential direction be provided with chamber, chamber inner wall is provided with wear ring 15, and y-type seal ring 9 is housed in the chamber.Between impeller and the pump case protecgulum, the cavity that forms between impeller and the pump case bonnet is water filling cavity 10, water filling cavity 10 is provided with intake pipe 11 and waste pipe 12.Be threaded between pump shaft and the impeller land, can be for convenience detach when breaking down, further increase work efficiency.
Y-type seal ring 3 in the packing filling chamber has solved the packing_seal problem effectively, when pump pressure improves, and the internal diameter of y-type seal ring and shaft seal, external diameter and pump case sealing, the pump internal pressure is high more, and sealing effect is good more.Y-type seal ring 4, y-type seal ring 8 solve the sealing problem of the impeller outside and inside pump casing effectively.Y-type seal ring 9 has solved the suction port sealing problem.Simultaneously, water filling in water filling cavity 10 can be lubricated and cooling the sealing and the working life of improving Y type envelope greatly to y-type seal ring.
