Guangdong Zhongxing Hydraulic Transmission Custom Couplings Delivered for a Russian Thermal Power Plant Project
Recently, Guangdong Zhongxing Hydraulic Transmission Co., Ltd. successfully passed the customer’s factory acceptance test for a high‑power variable‑speed coupling custom‑designed for the Novokuznetsk Thermal Power Plant in Russia, and the equipment has now been officially packed and dispatched. This product will be integrated into the project’s bubbling‑type steam boiler feedwater pump unit, with a rated input speed of… 2985rpm , with a transmission power of up to 5335kW , providing reliable core drive support for local energy production. 
As a key regional energy project for public welfare in Russia, the boiler feedwater pump unit at the Novolensk Thermal Power Plant has long operated continuously under heavy load, imposing stringent requirements on the speed‑control accuracy, operational stability, and power‑handling capacity of its drive equipment. Leveraging its deep technical expertise in hydraulic transmission and extensive experience in customized projects, Guangdong Zhongxing Hydraulic Transmission developed a tailored drive solution for the project, successfully securing the contract.
In response to the project’s specific operating‑condition parameters, the company’s technical team conducted targeted optimization and upgrades to key components, including the coupling’s flow‑channel geometry, cooling system, and bearing assembly. Through multiple rounds of simulation and bench testing, they ensured that the product maintains efficient, stable performance under high‑speed, high‑power operating conditions.
During the acceptance phase, a representative of the Russian client paid a special visit to the production facility, conducted an in-depth inspection of the manufacturing processes in the workshops, and participated throughout all performance‑testing procedures. 
The customer’s team successfully completed a series of factory acceptance tests, including full‑load performance testing, speed‑regulation accuracy verification, and vibration‑and‑temperature‑rise assessments, thoroughly validating both the manufacturing process and operational performance of the product. Ultimately, all technical specifications of this batch of variable‑speed couplings met or exceeded the contractual requirements, and the customer signed the acceptance confirmation document on the spot, commending the company’s technical expertise and product quality. 
At present, this batch of speed‑regulating couplings has been professionally packaged with rust‑proofing and reinforced for shipment, and has been officially dispatched to the project site in Russia.
The successful delivery of this product to the high-end overseas power market not only underscores Guangdong Zhongxing Hydraulic Transmission’s robust capabilities in customized R&D and manufacturing, but also marks another significant milestone in the company’s deep engagement with the global market. With years of dedicated expertise in the hydraulic transmission sector, the company has consistently leveraged technological innovation to drive growth and earned customer trust through superior quality and service. Looking ahead, Guangdong Zhongxing Hydraulic Transmission will remain focused on global industrial transmission needs, continuously refining its product portfolio and service ecosystem, thereby helping more cutting-edge Chinese industrial equipment reach the world stage and contributing to the high‑quality development of global industry.
