Product Description

Customized Heavy Duty Sand Dredging Pump made in China with cheap price


Heavy Duty Sand Dredging Pump is successfully developed by adopting advanced two-phase flow hydraulic design theory and hydraulic model. Reasonable cantilever ratio design and high-quality wear-resistant materials make the pump have the advantages of high efficiency and energy saving, long service life, high conveying concentration, and good anti-cavitation performance. Smooth operation, no leakage, and convenient maintenance.

It is used to transport corrosive, high-concentration slag slurry containing a large amount of solid materials. Such as heavy-medium coal preparation process, power station hydraulic slag removal system, blast furnace slag removal, mining, chemical industry, metallurgy, salt mud, etc.

This time we introduce the rubber-lined slurry pump with rubber flow parts. It adopts a double pump shell structure. The pump body and pump cover are equipped with replaceable wear-resistant and corrosion-resistant rubber linings (including impellers, sheaths, and protectors). Board etc.). The pump inlets are all horizontal, and the pump rotates clockwise from the driving direction.


The Advantages of Heavy Duty Sand Dredging Pump


Slurry pump is an indispensable conveying equipment in the concentrator. It is mainly used for the hydraulic conveying of solid materials such as first-stage grinding, second-stage grinding and tailings. Many mines have found that due to erosion wear, cavitation wear, chemical corrosion and electrochemical corrosion of the slurry pump during operation, the flow parts of the slurry pump are very easy to wear.

The flow parts of the slurry pump made of rubber materials have good wear resistance, corrosion resistance, long service life and easy replacement. However, for a long time, limited by the characteristics of rubber and its technical level, rubber flow parts are mostly used in medium and small slurry pumps and fine particle slurry transportation.

Failure cause of the rubber sheath


Some users will encounter the failure of the rubber sheath when using the heavy duty sand dredging pump. The rubber sheath of the slurry pump is a component used on the pump body, which is equivalent to the pump casing. Its main function is to reduce the wear of corrosive slurry to the pump body, thereby prolonging the service life of the slurry pump. Today we will analyze the cause of failure.


 Heavy Duty Sand Dredging Pump


① Excessive wear. The sheath is a component that is in direct contact with the slurry containing a large amount of solid particles. The high-speed moving slurry will have a strong impact on the sheath, causing the rubber sheath material to continue to wear. When the abrasion reaches a certain level, the rubber sheath will fail and the slurry will directly contact the pump body. At this time, the sheath should be replaced.


 Heavy Duty Sand Dredging Pump


②The temperature is too high. We know that the high temperature resistance of rubber is not high. When it reaches a certain temperature, the rubber will soften, reduce the degree of wear resistance, and even burn. At present, although rubber has made breakthroughs in high temperature, if the cooling system of the Heavy Duty Sand Dredging Pump is not good, the service life of the rubber will be greatly shortened.

③Serious cavitation. At the low pressure near the center of the impeller, the water vaporizes into bubbles. When the bubbles flow with the slurry to a place with higher pressure, the bubbles burst or shrink instantly, and the nearby slurry fills the void created by the bursting of the bubbles at a high speed. In this process In the medium, the slurry produces strong abrasion on the sheath.

④ Corrosion. Each kind of rubber sheath has its most suitable pH value. If it is higher or lower than this value, the service life of the sheath will be shortened.
