Power-driven feedwater pump coupler—choose the right coupler for more reliable water supply.
How can issues such as water hammer, water level fluctuations, bearing burnout, stuck control valves, and high energy consumption in power plant boiler feedwater pumps be addressed? Zhongxing Hydraulic Transmission has specifically designed solutions for feedwater pump speed‑control applications. The YOTFQZ, YOTC, and SVTL series deliver precise, stepless speed regulation, while their flexible buffering and vibration‑damping features significantly mitigate pump‑stop water hammer. With a starting overload factor of 1.5–1.8, they ensure smooth torque buildup, protecting the thrust bearings. G2.5‑grade dynamic balancing combined with efficient heat dissipation effectively addresses excessive oil temperatures and abnormal vibrations or noises. The upgraded DXA model extends the maintenance‑free interval to 2–3 years and achieves energy savings of 20%–40%. Backed by 60 years of industry expertise, these products are widely deployed by major power utilities such as China Huaneng, China Huadian, and China Datang, supported by end‑to‑end technical assistance to ensure more reliable water supply.

This article provides a detailed analysis of the energy consumption challenges associated with using a Roots blower in a vertical kiln at a cement plant—a scenario often referred to as “using a large horse to pull a small cart.” It also presents an energy-saving retrofit solution featuring the SVTL450 speed-regulating hydraulic coupling. The article explains how this solution replaces “throttling” with “speed regulation,” achieving energy savings of 20% to 40%, enabling soft starting, and providing precise airflow control. This retrofit is particularly suitable for fans ranging from 55 to 120 kW.
