CNSME PUMP

A slurry pump is a machine that increases the energy of a solid and liquid mixture through centrifugal force and converts electrical energy into kinetic and potential energy of the medium.It has strong wear resistance, high mechanical strength, does not age, and does not decompose toxins. It is widely used in metallurgy, mining, coal, chemical, power plants, sand extraction, environmental protection, municipal engineering and other industries, transporting suspended solid particles.　　After a certain usage time, the slurry pump sometimes trips.At this time, we need to restart the device.In fact, this process can more or less damage the device.In order to ensure its normal operation, some hazard inspections are required, faults are eliminated one by one according to conventional methods, and then deal with them in time. What is the reason?1. The motor is wet, resulting in excessive current.2. The voltage of the submersible pump is unstable.3. Control cabinet system failure.4. The quality of the submersible pump motor.5. The use of a head is much lower than the pump head, which leads to an increase in current, and excessive flow will lead to overcurrent.Solution: Control the outlet valve of the slurry pump to open to reduce flow and reduce current to the allowable current range, or change the impeller diameter to reduce the pump pressure head.

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:
