A large thermal power plant in Yunnan Province is solving the problem of ash and slag treatment of coal-fired units through technological innovation. The plant generates an average of 800 tons of high-temperature ash and slag slurry per day. The coal ash particles contained in it and the medium temperature of 50-60℃ pose a severe test to the wear resistance and corrosion resistance of the conveying equipment.
After receiving the purchase inquiry from the enterprise, the sales consultant of Changsha Zoomlion Pump Industry customized a selection plan for horizontal slurry pumps for it. According to the flow rate, head, medium temperature and composition, we recommend that the customer choose our company's 100ZJ-I-A33 type horizontal wear-resistant slurry pump. With three core technological breakthroughs, it has become the solution.
1.The self-developed high-chromium cast iron KmTBCr26 (HRC58-62) is adopted, combined with the precision casting process. The wear resistance of the flow-through components is significantly improved compared with the traditional materials.
2. In response to the characteristics of solid-containing media, an innovative "auxiliary impeller seal + stuffing box" combined sealing solution was adopted:
The pre-mounted auxiliary impeller forms a dynamic sealing barrier through centrifugal force.
The rear stuffing box adopts flexible graphite packing + water cooling system. The dual protection ensures a sealing life of over 3,000 hours (industry average 2,000 hours).
The above technical solution has been highly recognized by the customer, and a supply agreement was quickly reached with us. The first cooperation involved the purchase of 2 sets.
If the usage effect is indeed good, a long-term cooperation mechanism will be established subsequently to provide product support for improving the quality and reducing costs of the power plant.
I recently purchased the slag slurry pump from your company, and I must say it has been an outstanding addition to our industrial operations. Before using this pump, we faced frequent disruptions with our previous equipment—inefficiency in handling abrasive slurries and constant breakdowns plagued our workflow. However, your slag slurry pump has completely transformed this situation. Its robust construction and exceptional abrasion - resistance have proven invaluable.
Even when dealing with highly viscous and particle - laden slurries, the pump operates smoothly without any signs of premature wear. The efficiency is remarkable; it maintains optimal flow rates while consuming less energy than comparable models, significantly cutting our utility bills. What’s more, maintenance has become a straightforward task. The design allows easy access to key components, reducing downtime for checks and repairs. The technical support from your team during installation and operation was also top - notch.
They provided thorough guidance, ensuring we maximized the pump’s performance. In summary, this slag slurry pump combines durability, efficiency, and user - friendly design. It has enhanced our productivity and reliability. I wholeheartedly recommend this product to any industry dealing with challenging slurry - handling tasks—you’ll wonder why you didn’t switch sooner!
