Abstract

The utility model discloses a double-suction double-support submersible slurry pump which relates to a centrifugal impurity pump, and comprises a motor, a pump body and an impeller; the motor and the pump body are connected through a coupling; a shaft is arranged in the coupling; the impeller is arranged in the pump body and is fixedly connected with the shaft; the double-suction double-support submersible slurry pump is characterized in that the pump body is conical and is provided with symmetrical upper and lower ends; a pump cover is arranged outside the pump body, and the bottom end of the pump body is supported by a supporting leg; the pump cover is arranged outside the pump body, and forms a conical inner cavity with the pump body; one side of the pump body is also provided with a drainage port; the upper outer wall and the lower outer wall of the pump body are provided with water absorption runners to supply enough water to the inner cavity, so as to satisfy the water absorption of an upper suction opening and a lower suction opening. The double-suction double-support submersible slurry pump has the advantages of changing the impeller supporting method into a cantilever structure of single-surface supporting, preventing the defect that the impeller produces eccentric wear in operation, changing the status that the prior art only has one suction opening to absorb water, making up for the status that an impeller runner is easy to be blocked by large solid particles, and greatly improving the utility rate of energy.

Description

Double suction dual-gripper slag slurry pump under liquid
Technical field
The utility model relates to a kind of centrifugal transh pump, specifically is double suction dual-gripper slag slurry pump under liquid.
Background technique
Present common vertical anti-silt single suction slag slurry pump under liquid is made up of motor and pump substantially, motor and pump are direct-connected by coupling, the impeller form is a single suction formula impeller, it is centrifugal impurities pump, impeller sucks sewage in the pump case through the single face water sucking mouth, discharge by outlet pipe, because being single face, supports the impeller supporting form, cantilever structure, and working condition is bad, impeller is easy to generate eccentric wear therebetween in operation, and having only a water sucking mouth suction, the runner of impeller own is narrow, is stopped up by big solid particle easily, cause energy utilization rate not high, blowdown flow rate is few.
The model utility content
The technical problem that the utility model solved is to provide the laterally zygomorphic double suction dual-gripper of a kind of taper shape slag slurry pump under liquid.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of double suction dual-gripper slag slurry pump under liquid, by motor, the pump housing and impeller constitute, the motor and the pump housing are direct-connected by coupling, installation shaft in coupling, impeller is installed in the pump housing and with axle fixedlys connected, it is characterized in that: the described pump housing is conical, symmetry is provided with pump cover outside the pump housing up and down, supports by supporting leg, play the together support pump housing up and down, form conical inner chamber between the described pump cover and the pump housing, also be provided with drain opening, on the outer wall up and down of the pump housing suction runner is set in a side of the described pump housing, be used to supply with the sufficient water yield of inner chamber, satisfy suction inlet water absorption up and down.
Described pump cover is conical cover plate, supports by the trisection riser, forms the space runner in the middle of described cover plate up and down.
The joint of the described pump cover and the pump housing is placed with seal ring, is used for the enhanced leaktightness effect.
The utility model can make moisture abundance in the pump housing inner chamber after pump cover and the pump housing combination in use, and the top and bottom of impeller can be absorbed water with equal parts, discharge via the drain opening of side.
The beneficial effect that the utility model has with respect to prior art is that to have changed the impeller supporting form be the cantilever structure that single face supports, avoided impeller to be easy to generate the shortcoming of eccentric wear therebetween in operation, also change pump and had only a suction inlet suction, remedied the situation that impeller channel is easily stopped up by big solid particle, rate of energy has been improved greatly.
