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.

Power Plant Coal Mill Coupler — Choose the Right Coupler for More Efficient Grinding
2026-08-24
How do you select the right coupling for a coal mill’s high‑inertia, heavy‑load start? Zhongxing Hydraulic Transmission has specifically engineered its YOXv750 series—featuring an extended auxiliary chamber—to deliver ultra‑long soft starts of 22–30 seconds under low‑speed, high‑torque conditions typical of thermal power plant coal mills. The starting torque is smoothly controlled at 1.35–1.5 times the rated torque, completely eliminating mechanical shocks and motor trips. Its easy‑disassembly, split‑design allows maintenance without removing the motor. As a nationally recognized high‑tech enterprise, we provide end‑to‑end selection support, ensuring more reliable operation of your pulverizing system.
Metallurgical Crane Couplers — Choose the Right Coupler for Safer Lifting Operations

Many technicians choose couplings based solely on model numbers, only to find that the installed unit can’t handle the load, slips and overheats, or even burns out the motor. In fact, selecting the right coupling is straightforward: match the power rating to the speed, and verify that the input and output shaft diameters are compatible. This article explains in detail the two key criteria for choosing YOX‑series couplings, helping you make the right selection the first time—without any mishaps.
