Centrifugal pumps are a common fluid-conveying device in industrial production, and their stable operation is essential to production efficiency. However, during operation, a number of problems may arise, including abnormal vibration, insufficient flow rate, bearing overheating, etc. Yantai Longgang Pump Industry Co., Ltd. (hereinafter referred to as Longgang Pump Industry) responds to these common faults by offering a number of effective and dependable solutions that are based on years of technical accumulation and industry experience.
Common Problems of Centrifugal Pumps and Their Solutions
1. The pump cannot start or operate abnormally
Potential causes: power outages, motor damage, impeller jamming, and the inlet valve not being opened.
Solutions:
- Check the insulation performance of the power supply and motor to ensure stable voltage.
- Clean foreign matter in the pump chamber to prevent impeller blockage.
- Check whether the inlet and outlet valves are fully open to avoid air binding.
Advantages of the Longgang Pump Industry:
High-performance motors and anti-stuck impeller design are used to reduce the startup failure rate.
2. Insufficient flow rate or head
Potential causes: impeller wear, excessive clearance of the sealing ring, mismatched rotation speed, and leakage of the inlet pipeline.
Solutions:
- Replace the worn impeller or adjust the seal ring gap.
- Check whether the pump speed meets the design requirements.
- Check the pipeline system to ensure there is no leakage or blockage.
Technology of Longgang Pump Industry:
Use high chromium alloy impeller and precision casting technology to extend the service life of the impeller and improve pump efficiency
3. Excessive vibration or noise of the pump body
Potential causes: damaged bearings, unbalanced rotors, unstable foundation, and cavitation.
Solutions:
- Make sure the bearings are properly lubricated and replace any damaged ones.
- Adjust the dynamic balance once again.
- To lessen resonance, reinforce the pump base.
- Optimize the suction pipeline’s design to prevent cavitation.
Solutions of Longgang Pump Industry: Shock-absorbing brackets and high-precision bearings are included to enhance operating stability and successfully lessen noise and vibration.
4. Overheating of bearings or mechanical seals
Potential causes: insufficient lubrication, failure of the cooling system, seal failure, and poor alignment.
Solutions:
- Regularly add or replace lubricating grease.
- Check whether the cooling water system is unobstructed.
- Replace damaged mechanical seals to ensure installation accuracy.
Technology of Longgang Pump Industry:
Use imported high-temperature resistant bearings and double-end mechanical seals to improve wear resistance and high temperature resistance.
Technical and Strength Advantages of the Longgang Pump Industry
- Advanced manufacturing technology: To optimize the hydraulic model and increase pump stability and efficiency, CAD/CAE simulation design is used.
- High-wear-resistant materials: To prolong the service life, important parts such as impellers and pump casings are made of stainless steel, high-chromium alloy, and other materials.
- System of intelligent monitoring: Predictive maintenance is accomplished through the provision of remote monitoring and fault early warning capabilities.
- Thoughtful after-sales system: To guarantee clients’ worry-free production, a skilled technical staff offers on-site diagnosis and quick repair services.
