Sand Pump Used on Cutter Suction Dredger

2021/05/22

The sand pump used on the sand suction dredger is generally required to be horizontal, wear-resistant, and the impeller is durable.

The horizontal sand pump is a kind of impurity pump designed according to the two-phase flow theory, which is divided into 250pn-30, 250pn-35, 250pn-40, 350pn-24, 350pn-35, 350pn-45 and 400pn-22. The pump has the characteristics of high hydraulic efficiency, good wear resistance and stable performance when conveying the medium containing solid particles. The pump is suitable for inland river dredging, coastal dike reclamation, and coal mine, mine, power plant and other enterprises to transport slurry containing solid particles. The concentration of the conveying medium can reach more than 40%, and the medium particles can reach 50 mm. Scope of application: 1. It is suitable for inland river dredging, coastal dike reclamation, pumping mud and yellow sand from rivers, lakes and sea water reservoirs. 2. When coal mines, mines, power plants and other enterprises transport slurry containing solid particles, the concentration of transport medium can reach more than 40%, and the medium particles can reach 50 mm. Auxiliary equipment: need to install emptying device.

Structural features:

1. It is mainly composed of pump body, impeller, guard plate, pump cover, bracket and bearing components.

2. The material of pump body, impeller and guard plate can be made of gray cast iron, cast steel, wear-resistant alloy and non-metallic wear-resistant materials. Users can choose according to the purpose when ordering.

3. The shaft seal of the pump adopts the packing seal, and the high-pressure flushing water is added into the packing chamber to ensure the normal operation of the pump.

4. The turning direction of the pump is anticlockwise when viewed from the water inlet, and the outlet of the pump is on the right side of the horizontal direction when viewed from the water inlet. The outlet can be adjusted in the range of 360 degrees if it is needed on site. Material: pump shell can be cast iron, cast steel, alloy. The material of impeller and guard plate can be made of cast iron, cast steel, wear-resistant alloy and non-metallic wear-resistant material. Users can choose according to the purpose when ordering.

Features of sand suction vessel: it has the advantages of large flow, wide flow channel, and can transport all kinds of mud and sand media, with a variety of materials to choose from, which can flexibly adapt to a variety of working conditions.
