Self-balancing double-suction self-balance leaking hydrolysis feed pump developed by Jiangsu Feixiang Pump Manufacturing Co., Ltd. has been used in Hubei Dangyang Huaqiang Chemical Co., Ltd., Heilongjiang Haolianghe Fertilizer Plant More than 40 coal chemical, urea and other enterprises. According to Zhu Wuwen, deputy general manager of the company, the balance of axial force is a chronic problem of multistage centrifugal pumps. The traditional horizontal multistage pump uses a balance disc, a balance drum and a balance pipe to balance the axial force of the pump. The amount of leakage is large, the pump performance fluctuates greatly, and the wear and tear of the pump is easy to run. When the high temperature medium is conveyed, the maintenance cycle does not come out 3000 hours. The company developed the JFZY-MS double-suction self-balancing leak-free leaking feed pump has two patented technologies, the use of excellent hydraulic model, according to AP1610 international advanced standards of design and manufacture of self-balanced axial force, no leakage, pipe connections Convenient and effective solution to the traditional horizontal multi-stage pump axial force self-balancing problem is the upgrading of traditional chemical pump products. Leak-free hydrolytic feed pumps have great potential for retrofitting new coal chemical projects and urea plants. The domestic use of many deep hydrolysis urea plant, showing that can increase production efficiency, reduce consumption and extend the service life advantage. According to reports, the product was successfully developed in 2004, when the investment into Jilin Tonghua Chemical Co., Ltd., Shandong Tengzhou Ruida Chemical Co., Ltd., Inner Mongolia Wulashan Chemical Fertilizer Plant, Xinjiang Xinhua Chemical Fertilizer Co., Ltd. and other enterprises in the deep hydrolysis of urea plant Use, made significant economic and social benefits. Due to the large shaft diameter, high load bearing, inner segment and outer cylinder design, the bearing pressure grade of the pump is increased. The thermal expansion medium is even, stable and long-life when conveying high-temperature medium, which prolongs the equipment operation cycle.
