During operation, there are four types of common failures of slurry pumps: corrosion and abrasion, mechanical failure, performance failure and shaft sealing failure. These four types of failures often affect each other.

For example, the corrosion and abrasion of the impeller will cause performance failure and mechanical failure, and the damage of the shaft seal will also cause performance failure and mechanical failure.

1. Bearings Overheated

A. Too much, too little or deterioration of lubricating grease/oil will cause the bearing to heat up, and the appropriate amount and quality of oil should be adjusted.

B. Check whether the pump -motor unit is concentric, adjust the pump and aglign it with the motor.

C. If the vibration is abnormal, check whether the rotor is balanced.

2. Reasons and solutions that may causenon output of slurry

A. There is still air in the suction pipe or pump, which should be filled with liquid to discharge the air.

B. The valves on the inlet and outlet pipeline are closed or the blind plate is not removed, then the valve should be opened and the blind plate removed.

C. The actual head is higher than the maximum head of the pump, a pump with higher head should be employed

D. The rotation direction of the impeller is wrong, so the rotation direction of the motor should be corrected.

E. The lifting height is too high, which should be lowered, and the pressure at the inlet should be increased.

F. The debris is blocked the pipe or the suction pipeline is small, the blockage should be removed and the pipe diameter should be enlarged.

G. The speed does not match, which should be adjusted to meet the requirements.

3. Reasons and solutions for insufficient flow and head

A. The impeller is damaged, replace it with a new impeller.

B. Too much damage to the sealing ring, replace the sealing ring.

C. The inlet and outlet valves are not fully opened, they should be fully opened.

D. The density of the medium does not meet the requirements of the pump, re-calculate it.

4. Reasons for serious seal leakage and solutions

A. Improper selection of sealing element materials, replace suitable elements.

B. Serious wear, replace the worn parts and adjust the spring pressure.

C. If the O-ring is damaged, replace the O-ring.

5. Reasons and solutions of motor overload

A. The pump and engine (output end of the motor or diesel engine) are not aligned, adjust the position so that the two are aligned.

B. The relative density of the medium becomes larger, change the operating conditions or replace the motor with suitable power.

C. Friction occurs in the rotating part, repair the friction part.

D. The resistance (such as pipeline friction loss) of the device is low, and the flow will become bigger than required. The drain valve should be closed to obtain the flow rate specified on the pump label.

In the mining industry, the efficient handling, transportation, and disposal of tailings are crucial for the overall success and environmental sustainability of mining operations.Tailing slurry pumps play a significant role in this process, as they are responsible for the transportation of the tailings, which are the by-products of the mining process. These pumps are designed to handle the heavy and abrasive nature of the tailings, making them an essential component in mining operations.

Tailing slurry pumps are specifically designed to handle the high-density and abrasive nature of tailings, which are a mixture of water and finely ground rock particles.These pumps are typically utilized in large-scale mining operations where the volume of tailings is substantial. efficient transportation of tailings is crucial for the containment and disposal of these by-products, as well as for the overall safety and environmental impact of mining activities.

One of the key features of tailing slurry pumps is their ability to handle high concentrations of solids.These pumps are equipped with special design features, such as large impeller passages and heavy-duty construction, which enable them to handle the abrasive nature of the tailings without clogging or excessive wear. This ensures the continuous and reliable transportation of the tailings, minimizing downtime and maintenance costs.

Furthermore, tailing slurry pumps are designed to operate in harsh and challenging environments, such as high pressure and temperature conditions.This makes them suitable for the demanding conditions present in mining operations. Additionally, these pumps are available in a range of sizes and configurations to meet the specific requirements of different mining applications.

Overall, tailing slurry pumps are an essential component in the efficient handling and transportation of tailings in mining operations.Their ability to handle high-density and abrasive materials, as well as their reliability in harsh environments, make them indispensable for the success and sustainability of mining activities. As the mining industry continues to evolve, the importance of tailing slurry pumps in the overall process of handling tailings is only set to increase.

The sheath is also called the volute, because its shape is more like the shell of a snail. It's made of the same material as the impeller and there are many different materials. We determine the material to use according to the characteristics of the slurry.

Cast iron material: not wear-resistant, cheap.

High chromium alloy: wear resistance, corrosion resistance, in the slurry pump used more.

Natural rubber: wear-resistant, corrosion-resistant, generally conveying non-angular particles of the slurry used more, compared with high chromium alloy will be a little corrosion resistance.

A49 material: This material price is relatively high, generally used to transport more corrosive slurry. In the desulfurization pump used more.

The above are several materials commonly used in slurry pumps. In addition, 316 stainless steel, lined with ceramic material. These several are used less, generally for special grout will choose these two materials, and the price will be much higher than the other several.
