The original boiler room equipment of a large chemical group in Sichuan Province frequently encountered problems such as excessive vibration, reduced efficiency, and water leakage at the seal. It was necessary to replace the existing boiler feed water pumps. As a leading chemical enterprise with an annual output value of over 5 billion yuan, the production line has strict requirements for equipment stability. The new feed water pumps to be replaced must not only meet the water supply demand of 200 cubic meters per hour and a head of 600 meters, with water temperature as high as 100 degrees Celsius, but also control energy consumption costs. This poses a dual challenge of "efficiency + stability" to the pump suppliers. After receiving the customer's procurement information, Changsha Zoomlion Pump Industry promptly contacted the customer.
The entire process of implementing customized solutions
After on-site investigation by our technical team, it was found that the original water pump is a segmented balance disc multi-stage pump with packing seal. The equipment maintenance cycle is too short and there is a leakage problem. In response, we propose:
1.The self-balancing multi-stage centrifugal pump is adopted to replace the balance disc structure, and the alloy mechanical seal is selected as the sealing form, which effectively extends the maintenance cycle and solves the water leakage problem.
2. Optimize the hydraulic model, forge the process of the flow passage section, effectively extend the maintenance cycle, increase the continuous operation time, reduce maintenance costs, and achieve energy conservation and efficiency improvement.
3. Configure temperature, seismograph and other sensors to provide real-time early warnings of bearing temperature, vibration values, etc., providing a good foundation for timely troubleshooting and extending the service life of the water pump.
The project implementation creates a win-win outcome.
The project team completed the installation and commissioning of two sets of DG200-80x6 boiler feed water pumps within 40 days this time. Among them, the production took 35 days, and the installation and commissioning guidance and testing took 2 days. "From installation to after-sales response, it exceeded expectations!" Manager Wang from the customer's equipment department gave feedback. "This is crucial for our continuous production."
