Questions You Should Know about Dredger Pumps exporters

3&#; The flow of the dredging pump is insufficient or unstable

There are several reasons as below:

SGB supply professional and honest service.

1) Insufficient flow in a pump can often be attributed to issues with the suction pipe or bottom valve. Leaks in the suction pipe or bottom valve can disrupt the flow and reduce the pump&#;s effectiveness. It is important to check for any air leakage sources in these components and promptly address them by sealing or repairing them. Additionally, a blocked water inlet can restrict the flow. In such cases, it is necessary to clean out any sludge or blockages that may be obstructing the water inlet to restore the proper flow rate. Regular inspection and maintenance of these components are crucial to ensure uninterrupted and efficient operation of the pump system.

2) A common cause of insufficient pump flow is low voltage, which can result in reduced pump speed. To address this issue, check the power supply voltage and adjust it as necessary to maintain the appropriate level. Additionally, examine the running speed of the engine, especially in the case of a diesel engine. Ensure that the engine is operating at a stable and rated rotating speed, as variations can affect pump performance. Regular monitoring and adjustment of power supply voltage and engine speed are essential to maintain optimal pump flow and prevent issues related to insufficient flow.

3) If a pipeline is leaking or if air is present in the pump body, it is essential to promptly discharge the air from the pipeline. Accumulated air can adversely affect the pump&#;s performance and efficiency. By releasing the air from the pipeline, the system can be restored to normal operation. Regular inspection and maintenance of the pipelines are necessary to identify and address any leaks or air accumulation, ensuring a smooth and efficient flow of the fluid through the pump system.

4) If the seal ring or impeller of a pump experiences severe wear, it can result in an unstable flow. To address this issue, it is crucial to conduct regular inspections and promptly replace any severely worn seal rings or impellers. The wear of these components can cause disruptions in the fluid flow, leading to reduced efficiency and potential damage to the pump system. By identifying and replacing worn seal rings and impellers in a timely manner, the pump&#;s flow stability can be restored, ensuring optimal performance and preventing further complications. Proper maintenance and monitoring are key to detecting wear and taking appropriate corrective actions to maintain the pump&#;s functionality.

5) Insufficient water inlet depth at the bottom valve can lead to the entry of air during pumping operations. To address this issue, it is important to adjust the depth of the bottom valve based on the suction lift of the pump. By ensuring an adequate water inlet depth, air ingress can be minimized, promoting efficient and uninterrupted pumping. Proper adjustment of the bottom valve depth is essential to maintain a stable water supply, prevent airlocks, and optimize the pump&#;s performance. Regular monitoring and adjustment of the water inlet depth in accordance with the pump&#;s specifications are necessary to mitigate air entry and maintain smooth operation.

6) If the pump works normally within a period of time after startup, but the current gradually decreases and the flow is obviously insufficient, and this problem still occurs after restarting the normal operation for a period of time, mostly because the slurry or other sundries are accumulating in the suction pipe, it may be caused by the pump cavitation. In serious cases, there will be large noise in the pump and obvious vibration of the pump head. At this time, the forebay and suction pipe should be thoroughly cleaned, Increase the length of the mixing device to reduce the settlement of the slurry.

4&#; The slurry pump does not absorb water (or cannot pump slurry)

There is air in the pump body or air accumulation in the water inlet pipe, or the filling water is insufficient, the pump packing is not tight and leaking, and the gate valve or flap door is not tightly closed. Solutions: first raise the water pressure, then fill the pump body with water, and then start the machine. At the same time, check whether the check valve is precise and whether the pipeline and discussion have signs of air leakage. If air leakage is found, apply lubricating oil or blending paint at the discussion place after disassembly, and tighten the screws. Check the oil seal ring of the water pump shaft. If it is worn and strained, replace it with a new one. Leakage or air leakage of pipeline. The nut may not be tightened during installation.

5. Conclusion

The following is a summary of common problems and corresponding solutions in the use of dredging pumps:
(1) Pump efficiency decreases: The efficiency of the dredging pump may be affected by various factors, such as wear of the pump blades, blockage inside the pump, insufficient opening of the inlet valve, etc. Solutions include regular inspection and replacement of worn parts, clearing blockages inside the pump, ensuring the inlet valve is fully open, etc.
(2) Clogging of the pump: The dredging pump may be clogged when handling mud containing solid particles, causing the pump to fail to operate normally. Solutions include increasing the dilution of the mud, regularly cleaning the particle deposits inside the pump, and enhancing the pump&#;s anti-clogging ability.
(3) Pump leakage: The pump seal may have leakage problems, resulting in energy loss and mud leakage. Solutions include inspecting and replacing worn or damaged seals, installing seals correctly, ensuring the finish of the sealing surface, etc.
(4) Pump vibration and noise: Excessive vibration and noise may occur during operation of the dredging pump, which affects the performance and life of the pump. Solutions include checking and adjusting the pump installation position, balancing the rotating parts of the pump, adding vibration damping measures, etc.
(5) Motor overheating or failure: The motor of the dredge pump may overheat or fail due to excessive load, poor operating conditions, etc. Solutions include regularly checking the operating status of the motor, ensuring the motor is well ventilated, preventing overload operation, etc.
(6) Pump leakage: The dredging pump may have water leakage problems during operation, which may be caused by seal failure, pump body damage, etc. Solutions include inspecting and replacing pump seals, repairing or replacing damaged pump body parts, and more.

By promptly discovering and solving these common problems, you can ensure the normal operation of the dredger pump and extend its service life. Measures such as regular maintenance, proper operation and selecting the appropriate dredge pump model and material can also help prevent problems from occurring. When encountering problems that cannot be solved, it is recommended to seek professional help and support.
