When selecting a hydraulic coupling, don’t rely solely on the model number! Verify the power rating, speed, and shaft diameter to ensure you choose the right one the first time—avoid costly mistakes.

2026-09-28

When buying a hydraulic coupling, do you just pick the model number—only to find that once installed, it can’t drive the load, slips and overheats, or even burns out the motor? This article clarifies two key selection criteria: matching power and speed, and verifying input and output shaft diameters. It also includes a practical checklist, ensuring even beginners can make the right choice on their first try.

Power-driven feedwater pump coupler—choose the right coupler for more reliable water supply.

2026-09-15

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.
