Horizontal Slurry Dredge Pump

Description:

Horizontal slurry dredge pump is a specialized pump designed to handle slurry fluid mixtures containing solids and liquids. It is commonly used in industries where solid-liquid mixtures need to be moved, such as mining, pulp and paper, chemical processing, and dewatering treatment.

When selecting a slurry pump for mine tailings, it is important to consider the specific application, pump capacity, head, solids content, partical size,pump material, and other relevant factors. The type of slurry pump to choose depends on the specific pumping requirements and the physical properties of the slurry being pumped.

Composition of Horizontal slurry dredge pump
Horizontal slurry dredge pump, in addition to the pump head part (including front and rear pump shell, volute, front and rear protection plate, impeller, etc.) structure is different, the rest of the structure is similar, using the same series of transmission parts, the following according to the pump head part, shaft seal part of the machine transmission part.
1, pump head part Horizontal slurry dredge pump double pump shell structure, and the front pump shell, the rear pump shell and with a replaceable flow section (including impeller, volute, cover plate liner, frame plate liner). The front and rear pump shell is made of gray cast iron or ball ground cast iron according to the working pressure. It is vertically open and bolted. The rear pump shell has a stop and the bracket is bolted. Pump outlet can be rotated according to eight angles, impeller front and rear cover plate with back blades to reduce leakage, improve pump life and efficiency, each type of pump inlet are horizontal direction, from the direction of the drive pump clockwise rotation.
Second, the shaft seal part: the shaft seal has three forms, the auxiliary impeller shaft sealing machine packing shaft seal, mechanical seal.
1. Expeller seal: When the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure, a single pump or a multi-stage series third-stage pump can use the auxiliary impeller shaft seal, which has the advantages of non-diluting pulp and good sealing effect.
2.Gland packing shaft seal: packing shaft seal structure is simple, easy maintenance, need to use sealing water, for not suitable for the condition of the auxiliary impeller shaft seal and pump suction conditions can be used packing shaft seal.
3. Mechanical seal: For the conditions that are not suitable for the above two types of shaft seals, mechanical seals are used to reduce the number of maintenance of the shaft seals.
4. Transmission part: This series of pumps all use the same series of transmission, including bracket and bearing assembly, pump shaft diameter, good rigidity, short cantilever, in harsh working conditions will not bend and vibration. Bearing selection of single row tapered roller bearing and angular contact ball bearing combination use, can withstand the jump of large axial and radial load, bearing using lithium grease lubrication, the advantages of this lubrication is: high oil film strength, grease adhesion, not easy to lose, longer use time; The sealing is simple, and the bearing body is equipped with a sealed end cover at both ends, which can effectively prevent pulp and other dirt from entering the bearing.

Third, the factors of slurry pump wear have the following aspects:
1. Medium characteristics
2. Material characteristics
3. Abrasive and material interaction

Advantages slurry pumps:

Firstly, they are designed to handle mixtures with high solids content, making them suitable for various industrial applications where solid-liquid mixtures need to be moved.

Secondly, slurry pumps for mine tailings have a longer lifespan than regular pumps because they are designed to handle abrasive materials.

Finally, slurry pumps provide efficient and reliable pumping performance, ensuring that the process is not disrupted by pump failure.

Application:

The applications of slurry pumps are widespread. In mining operations, slurry pumps are used to transport mined materials out of the mine and to process them further. In pulp and paper manufacturing, slurry pumps are used to transport pulp and paper stock between processing stages. In chemical processing, slurry pumps are used to move solid-liquid mixtures in various processes, such as mixing, reacting, and filtering.

Finally, in sewage treatment plants, slurry pumps are used to transport sludge and other solid waste for further processing or disposal.

The driving method of slurry pump for mine tailings is an important factor that affects its performance and efficiency. In general, there are DC,CV,CRZ,ZV
