CNSME PUMP

The selection of slurry pumps is a very important task. There are many types of slurry pumps. We must choose the appropriate pump type according to the properties of the slurry and meet the working conditions.According to its purpose, it includes ash pump, ash pump, circulation pump, desulfurization pump, filter press feed pump, liquid submersible pump, chemical pump, corrosion-resistant pump, submersible slurry pump, etc.If the choice is not suitable, it will cause the pump to work in large or small flow, high or low head, material to resist wear, corrosion, etc. This is not only in the use of which cannot meet production requirements, and inefficient, short life, causing waste and loss.In severe cases, other accidents may occur even in emergencies as the work is not going as expected.The selection of the model is mainly based on flow and head.It is necessary to know the small flow and large flow required by the device. When selecting a pump, it is based on the large flow rate. If the large flow rate is not given, it can usually be 1.11 times the normal flow rate.In addition to considering the low intake liquid level and high water transfer height, the head required for the device system should also be considered.Generally, when selecting a pump, take 1.04 to 1.11 times the system head.After determining the two performance parameters of flow rate and head, determine which pump type is used according to the requirements of the device system.In addition to its strong wear resistance, it also has the characteristics of high efficiency, good cavitation performance, stable operation, long service life and low speed and high head.What parameters are needed to summarize the selection of slurry pumps?1. Must parameters: head, flow, industry. These are the parameters that must be known for selection and are the basic conditions for slurry pump selection calculation; 2. In addition to the above parameters, if there are: slurry concentration, pipeline, pH value, even altitude, natural temperature, slurry temperature, etc., you can accurately select a better slurry pump.

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:
