How to better utilize CQB magnetic pump

2025-01-21

In the context of the rapid development of the domestic pump industry, fluoroplastic magnetic pumps are well-known for their excellent properties. However, you know that there are two major components under the umbrella of pneumatic plastic magnetic pumps, namely COB magnetic pumps and IMD magnetic pumps. It is much simpler to learn about CQB magnetic pumps after understanding fluoroplastic magnetic pumps. We will not go into too much detail here. This article will explain how to use CQB magnetic pumps well. Firstly, let's talk about the installation of CQB magnetic pump (similar to IMD magnetic pump):

(1) Magnetic pumps should be installed horizontally and not vertically. The plastic pump body should not bear the weight of the pipeline. For special requirements for vertical installation, the motor must face upwards.

(2) When the suction liquid level is higher than the pump axis line, open the suction pipeline valve before starting. If the suction liquid level is lower than the pump axis line, the pipeline needs to be equipped with a bottom valve.

(3) Before using the pump, it should be checked that the motor fan blades rotate flexibly without any jamming or abnormal noise, and all fasteners should be tightened.

(4) Check if the rotation direction of the motor is consistent with the direction mark of the magnetic pump.

(5) After the motor starts, slowly open the discharge valve and adjust it to the desired opening after the pump enters normal operation.

(6) Before the pump stops working, the discharge valve should be closed first, and then the power should be cut off.

It is important to pay special attention to the following points when using CQB magnetic pumps, otherwise it may cause damage and shorten its service life.

(1) Due to the fact that the cooling and sliding of magnetic pump bearings rely on the medium being transported, it is absolutely prohibited to operate them in an empty manner, while also avoiding the spatiotemporal transport caused by power outages and subsequent layering during operation.

(2) If the conveyed medium contains solid particles, a filter screen should be added to the pump inlet; if it contains ferromagnetic particles, a magnetic filter should be added.

(3) The ambient temperature of the pump during use should be less than 40 ℃, and the temperature rise of the motor should not exceed 75 ℃

(4) The medium being transported and its temperature should be within the allowable range of the pump material (see Appendix B for the operating temperature of engineering plastic pumps (60 ℃), the operating temperature of metal pumps (100 ℃), the suction pressure of the conveying system should not exceed 0.2MPa, the maximum working pressure should be 1.6MPa, the density should not exceed 1600Kg/m ², and the viscosity should not exceed 30x10-6 ㎡/s, which is a liquid free of hard particles and fibers. (V) For the medium that is prone to precipitation and crystallization, it should be cleaned in a timely manner after use and the accumulated liquid in the pump should be drained.

(6) After 1000 hours of normal operation of the magnetic pump, the wear of the bearings and end face moving rings should be disassembled and inspected, and vulnerable parts that are no longer suitable for use should be replaced.

How to improve the flocculation effect of polyacrylamide?

2025-01-20

To improve the flocculation effect of polyacrylamide, you can consider the following strategies:

 

1. Adjust the polymer dosage: The optimal dosage of polyacrylamide depends on various factors such as the type and concentration of the suspended particles, pH of the solution, and temperature. Conduct jar tests or pilot-scale experiments to determine the optimum dosage for your specific application. Increasing the dosage within the optimal range can enhance the flocculation effect.

 

2. Optimize the polymer chain length: The molecular weight of polyacrylamide significantly influences its flocculation performance. Higher molecular weight polymers often exhibit better bridging and flocculating properties. Experiment with different molecular weight ranges to find the most suitable polymer for your application.

 

3. Modify the charge of the polymer: The charge of polyacrylamide can be adjusted to enhance flocculation. Anionic polyacrylamide is commonly used for flocculating negatively charged particles, while cationic polyacrylamide is effective for treating positively charged particles. Non-ionic or amphoteric polyacrylamide can be used for neutral or mixed charge systems.

 

4. Optimize the pH of the solution: The pH of the solution can significantly impact the flocculation performance of polyacrylamide. In some cases, adjusting the pH to an optimum range can greatly enhance flocculation. Conduct pH titration tests to determine the optimal pH for flocculation in your system.

 

5. Utilize coagulants: In combination with polyacrylamide, coagulants such as alum or ferric chloride can improve flocculation. Coagulants destabilize the particles, while polyacrylamide aids in bridging and flocculation. The combination of coagulation and flocculation processes can lead to improved overall performance.

 

6. Increase mixing intensity: Adequate mixing helps promote contact between the polymer and the suspended particles. If the mixing intensity is insufficient, consider optimizing the mixing conditions, such as increasing the mixing speed, using different impeller designs, or extending the mixing time.

 

7. Use a multistage polymer addition: For complex or hard-to-flocculate systems, a multistage polymer addition technique can enhance the flocculation effect. By adding polyacrylamide in multiple stages, each polymer addition can target different stages of flocculation, leading to improved floc strength and settling efficiency.

 

8. Conduct pilot-scale or field trials: To validate the efficacy of polyacrylamide and optimize its application, it is recommended to perform pilot-scale or field trials. These trials allow you to assess the flocculation performance under actual process conditions and make necessary adjustments accordingly.

 

Remember to always follow safety guidelines and consult with experts in the field of polymer flocculation to ensure the appropriate and effective use of polyacrylamide.

How to increase the sedimentation rate of polyacrylamide?

2025-01-20

To increase the sedimentation rate of polyacrylamide, you can consider the following strategies:

 

1. Increase the molecular weight: Polyacrylamide is available in various molecular weights. Using a high molecular weight polyacrylamide can enhance the sedimentation rate. Higher molecular weight polymers tend to have larger particle sizes and greater settling velocities.

 

2. Adjust the concentration: Increasing the concentration of polyacrylamide in a solution can also accelerate sedimentation. Higher polymer concentrations result in denser particle packing, leading to faster settling.

 

3. Modify the pH: The pH of the solution can affect the sedimentation rate. In some cases, adjusting the pH to a specific value can encourage the formation of larger polymer aggregates, which settle more rapidly. Experiment with different pH values to optimize the sedimentation rate.

 

4. Apply a flocculant agent: Adding a flocculant agent to the polyacrylamide solution can enhance the sedimentation rate by promoting the aggregation of fine particles. Flocculants can be inorganic salts, organic polymers, or specific chemicals tailored for the purpose.

 

5. Utilize centrifugation: Sedimentation can be accelerated by using centrifugation. By subjecting the polyacrylamide solution to high centrifugal forces, you can separate the particles quickly based on their sedimentation rates. Centrifugation is especially useful when dealing with very fine particles or when speed is crucial.

 

6. Control the temperature: The temperature of the solution can have an impact on the sedimentation rate. Higher temperatures reduce the viscosity of the solution, allowing faster settling. However, it is important to ensure that the temperature does not cause degradation or other undesirable effects on the polyacrylamide.

 

7. Optimize stirring or agitation: Gentle stirring or agitation can prevent settling and maintain the suspension. However, if you need to increase the sedimentation rate, reducing or stopping the agitation can allow the particles to settle faster.

 

Remember to conduct small-scale experiments and optimize these conditions based on your specific requirements and the characteristics of the polyacrylamide you are using.
