Amphibious vertical sand discharging pump

Abstract

The invention discloses an amphibious vertical sand discharging pump. The amphibious vertical sand discharging pump comprises a barrel-shaped pump body, wherein a water inlet is formed in the bottom of the pump body, and a water outlet is formed in the top of the pump body. A top cover, an upper bearing pedestal, a middle bearing pedestal, a lower bearing pedestal and a base are sequentially arranged in the pump body. The amphibious vertical sand discharging pump is characterized in that an axial flow type impeller is arranged at the end of a rotary shaft of a water pump motor, and an overflowpipe connected with a water inlet section is arranged on the inner side of the water inlet. The amphibious vertical sand discharging pump has the advantages that a relatively closed environment is formed by a self-suction water supply chamber, then the self-suction capacity of the pump body is greatly improved, the amphibious function is achieved, and the lift of land use is greatly improved; through a multi-stage impeller arranged on the rotary shaft in a sleeving manner, the lift of the pump body is increased, the problem that the pump inner pressure is too high is effectively solved by theoverflow pipe, and therefore the problem that liquid is leaked out to pollute the environment is effectively solved; and the axial flow type impeller guarantees that the total lift of the motor is free of overloads.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and more specifically relates to an amphibious vertical sand discharge pump. Background technique [0002] At present, the existing submersible sand discharge pump is composed of a spout, a diversion sleeve, a submersible motor, an impeller, a guide vane, a pump body, a water-absorbing base, and a filter screen, and has an electromechanical integrated structure. The water suction port is located in the filter screen. The submersible sand discharge pump must be submerged into the water when the user uses it. It is difficult to install, transport and move, and it is easy to block and cause mechanical failure. The traditional self-priming pump is composed of a non-submersible motor, a water suction flange, a water storage container, and a water outlet flange. It cannot be submerged in water, and the fixed installation cannot be moved. Once the pump is submerged, it will fail, causing diffic...
