Single sand suction device adopting anti-abrasion structure and sand suction method

Abstract

The invention provides a single sand suction device adopting an anti-abrasion structure and a sand suction method. A traditional sand suction pump cannot be used for pumping a medium with large viscosity, the lift and the efficiency of the pump can be reduced sharply caused by the increase of the viscosity of liquid, the viscosity of the medium is limited to be within 114cm, and the requirements of the radial clearance and the axial clearance between a sand suction pump impeller and a pump body are stricter and bring difficulties to machining and assembly processes. The single sand suction device adopting the anti-abrasion structure comprises an adjusting valve (10), wherein the regulating valve is connected with a discharge pipeline (9), and the discharge pipeline (9) is connected with adischarge outlet (8); a discharge outlet is connected with a pump shell (2) through a pipeline; the pump shell is connected with a suction pipeline (5); and the suction pipeline is connected with a connecting flange (11), and the connecting flange is connected with a one-way bottom valve (6) through a pipeline. The single sand suction device is suitable for extracting and conveying medium with strong abrasion resistance such as various kinds of yellow sand and ore sand.

Description

Technical field: [0001] The invention relates to a single sand suction device and a sand suction method using an anti-abrasion structure, a pump suitable for various working conditions, such as transporting acid, various corrosive pulps in the smelting industry, various sewage in the environmental protection industry, etc. Corrosion-resistant and wear-resistant, it can be used in a wide range of applications. Background technique: [0002] Mortar pumps mainly refer to water pumps used to transport mortar, generally centrifugal pumps. The sand pump mainly pans sand on the seabed, and pumps sand from river embankments. Mortar pump means more mortar, the efficiency is low, the highest is not more than 55%, the efficiency of the traditional sand suction pump is 20-40%, which hinders its development in the direction of high power. Traditional sand suction pumps cannot be used to pump viscous media, because as the viscosity of the liquid increases, the head and efficiency of the...

AI Technical Summary

Problems solved by technology

Traditional sand suction pumps cannot be used to pump viscous media, because as the viscosity of the liquid increases, the head and efficiency of the pump will decrease sharply, and the viscosity of the medium is limited within 114 centistokes. The sand suction pump impeller and pump body The stricter requirements for the radial clearance and axial clearance between them bring certain difficulties to the processing and assembly process
