As a kind of equipment widely used in industrial filtration, the stability and efficiency of the performance of the filter press is crucial to the smooth running of the production process. In the actual use of the process, sometimes there will be filter press pump feeding slow problem, affecting the filtration efficiency. In this paper, we will discuss in depth the common causes of slow feeding of filter press pumps and put forward corresponding solution strategies.

First, filter press pump feeding slow cause analysis

1. Conveying pipeline blockage: If the conveying pipeline is blocked when the filter press pump is conveying materials, it will lead to poor material flow and slow down the feeding speed. Possible reasons include the inner wall of the pipeline is not smooth, the bending radius of the pipeline is too small, and the material contains impurities.

2. Pump speed is too low: The speed of the pump is an important factor affecting the feeding speed. If the pump speed is too low, it will result in a reduction in the pump output flow rate, thus affecting the feeding speed. Possible causes include motor failure, loose or worn drive belts, and mechanical failure of the pump.

3. Insufficient suction of the pump: the filter press pump needs to have a certain suction to absorb the material in the process of conveying the material. If the suction of the pump is not enough, it will lead to sucking up the material at a slower speed, thus affecting the feeding speed. Possible reasons include low pressure at the suction port of the pump and cavitation.

4. Influence of material characteristics: different materials have different characteristics such as fluidity, particle size distribution, water content, etc., and these factors will affect the feeding speed of the filter press pump. For poor fluidity, large particle size, high water content of the material, the feeding speed may become slower.

5. Improper operation: In the process of using the filter press pump, if it is not operated properly, such as frequent starts and stops, overloaded operation, etc., it may lead to the pump's loading speed to become slower.

Second, to solve the filter press pump feeding slow method

In response to the above possible causes, here are some ways to solve the slow feeding of the filter press pump:

1. Cleaning or replacing pipes: For slow loading problems caused by clogged pipes, measures such as clearing the clog, replacing the pipes or increasing the bending radius of the pipes can be taken to restore smoothness to the pipes.

2. Check and adjust the speed of the pump: check whether the pump motor and transmission device work properly, adjust the speed of the pump to the normal range to ensure that the output flow of the pump meets the requirements.

3. Improve the suction of the pump: check whether the suction port pressure of the pump is normal, if necessary, you can adjust the working parameters of the pump or take other measures to improve the suction port pressure. Pay attention to prevent the occurrence of cavitation.

4. Improvement of material characteristics: For materials with poor fluidity, large particle size and high water content, measures such as adding flow improvers, crushing large-size materials and reducing water content can be taken to improve the fluidity of the materials, thus speeding up the feeding speed.

5. Standardised operation: In the process of using the filter press pump, irregular operations such as frequent starting and stopping and overloading should be avoided. Operate in accordance with the specified operating procedures to ensure the normal operation of the pump and the feeding speed.

6. Regular maintenance: Regular maintenance of the filter press pump, cleaning pipes and pump body, replacing worn parts, checking seals, etc., in order to keep the pump in good working condition and prolong its service life.

7. Seek professional help: If none of the above methods solves the problem, it is recommended to seek professional help in order to better diagnose the problem and fix it.

Through the above analysis, we can conclude that the reasons for the slow feeding of the filter press pump mainly include the clogging of the conveying pipeline, the low speed of the pump, insufficient suction, the influence of material characteristics and improper operation. In order to solve this problem, we need to start from many aspects, including cleaning or replacing the pipeline, checking and adjusting the speed of the pump, improving suction, improving material properties and standardising operation. In order to ensure the efficient and stable operation of the filter press pump, we should also pay attention to the regular maintenance of the equipment. In the event of equipment failure, we should seek professional help in a timely manner to repair, so as not to bring unnecessary losses to the production of equipment downtime for a long time. In the actual use of the process, we should also pay attention to the operating conditions of the equipment and performance changes, in order to find and solve potential problems in a timely manner. Strengthen the daily inspection and maintenance of equipment is also an important measure to ensure the normal operation of equipment. Through regular inspection and maintenance of the key parts of the equipment and wearing parts, you can find and deal with potential problems in a timely manner, to avoid the occurrence of serious equipment failure or downtime. Strengthening the daily maintenance of equipment can also extend the service life of equipment and reduce maintenance costs. Therefore, operators and maintenance personnel should fully understand the importance of routine maintenance, and take effective measures to ensure the normal operation of the equipment and the use of results.
