CNSME PUMP

The selection principles for slurry pumps and motors are very important It is mainly to determine the model specifications, type and the model, specifications and type of the motor to be used The selection of pumps and motors should follow the following principles: 1. Meet performance requirements: The performance of the pump mainly refers to the flow rate, head, and cavitation margin of the pump, followed by the speed, power and efficiency of the pump The flow rate and head of the pump are often valued by people, but the cavitation margin of the pump is often ignored In fact, when the cavitation of the pump is not met It will reduce the performance of the pump and shorten its life, and it will be unusable in severe cases 2. Meet process and installation requirements: In addition to the above performance requirements, the process requirements must also meet the temperature, properties, viscosity, corrosiveness and Containing impurities, etc. At the same time, the requirements for installation must also be considered 3. Economic efficiency: It is necessary to consider the economic efficiency of both one-time investment and long-term use costs One-time investment refers to the cost of purchasing pumps, motors, pipelines and the construction investment of pump stations Long-term use economy considers power consumption and pipeline hydraulic loss The life and maintenance cost of pumps and motors 4. Convenient installation, use, maintenance and repair of pumps The above are the selection principles of slurry pumps and motors Whether the selection is correct or not directly affects whether the pump meets the use requirements, is economical and easy to use If the selection is inappropriate, it will cause uneconomical operation and convenient use and maintenance Short life, high purchase cost, or even unusable So the selection of pumps and motors is an important task

Can mechanical seals be used in slurry pumps for easily crystallized ore pulp?

It is recommended to use: expeller + packing seal: the expeller generates centrifugal force to block particles from entering the sealing area, the packing seal is low-cost and resistant to a certain amount of crystallization (regular maintenance is required).

Pumps for Quartz Sand_Rubber-Lined Slurry Pumps in Quartz Sand Beneficiation Equipment

Quartz sand beneficiation focuses primarily on purification, a technically challenging separation process aimed at removing minor or trace impurities from quartz sand to produce refined quartz sand or high-purity quartz sand. Common purification techniques employed domestically and internationally include: Washing, Classification & Desliming, Scrubbing, Magnetic Separation, Flotation, Acid Leaching, and Microbial Leaching.

The Ultimate Guide to Slurry Pumps: Types and Applications

Selecting the right slurry pump ensures efficient performance, especially when dealing with high-volume and abrasive slurries. The ideal pump depends on the application, material compatibility, and operational demands.

Diagnosis Methods for Cavitation in Warman Slurry Pumps

The following techniques can be used to determine whether cavitation is occurring in a slurry pump:a. Ultrasonic testing b. External noise monitoring c. Vibration analysis

Horizontal Slurry Pumps: Principles & Application

Because they offer longevity, efficiency, and adaptability, horizontal slurry pumps are crucial for sectors handling abrasive slurries. Knowing their values, applications, and maintenance needs allows businesses to maximize performance and reduce expenses.

Commissioning of Slurry pumps

Slurry pump commissioning must be strictly conducted in accordance with established procedures: Prior to startup, first activate the shaft seal water and adjust it to the specified pressure. Fully open the inlet valve. For non-backflow pumps, water must be injected. After opening the outlet valve to one-quarter, initiate startup; During operation, monitor flow rate, head, current, vibration, and bearing temperature (temperature rise ≤35°C, maximum ≤75°C). Mechanical seal leakage should be ≤3-5 ml/h. Before stopping the pump, flush with clean water for 30 minutes, close the outlet valve first, then shut down the pump, and finally close the shaft seal water and inlet valve. It is strictly prohibited to fully open the outlet valve when stopping the pump to prevent water hammer. Throughout the entire trial operation process, ensure that parameters remain stable, avoid cavitation and overload conditions, to ensure safe operation of the equipment.

Common Problems During Feeding of Slurry Pumps

When a slurry pump malfunctions during operation, the first step is to identify the cause of the failure. Corresponding repair measures should be taken based on the characteristics of the failure and maintenance experience.

Aspects to Pay Attention to for Slurry Pumps to Run Stably and Efficiently in Series

The advantage of slurry pumps in series is that multiple pumps are arranged in one pump station, which is convenient for installation, maintenance, operation and management, with a total low cost, it can realize overall automatic management. The following aspects should be noted when selecting slurry pumps in series:

The Hazards to Slurry Pumps if Running in a Low Flow Area for a Long Time

The slurry pumps we often use are a type of centrifugal pump. It mainly drives the slurry mixture to rotate through the high-speed rotating impeller blades, and throws out the slurry to achieve the purpose of transportation.

The methods for adjustment the flowrate of slurry pumps

The flowrate adjustment method of slurry pump can be selected in various ways according to different needs and occasions. The following are some common flowrate adjustment methods:
