Title: Dalian Mairuisheng Transmission: Taking Proven Chinese Engineering and Customized Fluid Coupling Solutions to the Global Market

Subtitle: With over a decade of dominance in China's core industries and a complete product range from model 274 to 1150, Dalian Mairuisheng leverages its engineering prowess to offer high-value, optimized hydrodynamic drive solutions worldwide.

FOR IMMEDIATE RELEASE

DALIAN, China – January 26, 2026 – Dalian Mairuisheng Transmission Mechanism Equipment Co., Ltd., a trusted partner in China's mining, port, and heavy industrial sectors, today announced its strategic expansion into international markets. The company will offer globally high-performance, cost-effective, and highly customized Fluid Couplings solutions, built upon profound technical expertise and validated success in demanding domestic applications. Dalian Mairuisheng boasts a mature portfolio capable of manufacturing a complete series of hydrodynamic couplings, from compact units (e.g., Model 274) to extra-large drives (e.g., Model 1150), and possesses the advanced technical capability to custom-engineer Magnetic Couplings for specialized applications.

Headquartered in Dalian, a major industrial hub in China, Mairuisheng's reputation is rooted in a deep understanding of the country's most challenging industrial environments. Domestically, its Fluid Couplings are critical components in the drive systems of major mining conglomerates and bulk material handling conveyor belts, celebrated for exceptional reliability and superior adaptation to local operating conditions. The company now aims to bring this philosophy of "creating customer value through engineering intelligence" to the global stage.

1. Core Strength: Complete Product Series and Deep Customization Capability

Mairuisheng's competitive edge lies in its comprehensive product matrix and agile design responsiveness.

   Full-Series Coverage: The production line is成熟 (mature) in covering standard and non-standard models such as 274, 366, 560, 750, and 1150, ensuring a matching hydrodynamic coupling is available for every drive need, from small auxiliary machinery to high-power main drives.

   Deep Customization: Going beyond standard catalogs, the company's engineering team excels at providing全方位 (comprehensive) customization—including connection dimensions, cooling methods, and auxiliary chamber structures—based on specific client load characteristics, spatial constraints, and process requirements.

   Technical Extension: Leveraging long-term accumulation in fluid power transmission, the company has successfully developed and applied Magnetic Coupling technology, offering an efficient and reliable alternative for scenarios requiring absolute密封 (seal) and leak-free power transmission, such as in chemical and offshore platform applications.

2. Value Demonstration: A Classic Case Study Highlighting Engineering Optimization

The value of Dalian Mairuisheng is embodied not just in manufacturing, but in its engineering capability to optimize overall solutions for clients. A quintessential case from China's mining industry clearly illustrates this point:

A large mining customer, while selecting equipment for a long-distance, high-load conveyor, initially specified a relatively complex Dual-Chamber Fluid Coupling based on conventional design practices to achieve ideal soft-start and overload protection performance. However, when Dalian Mairuisheng's engineers became involved, they did not simply produce according to the drawings. Through meticulous re-calculation and dynamic simulation analysis of the drive motor's power, speed, load inertia, and the conveyor's actual starting resistance, they proposed an innovative alternative: using a one-size-larger standard model Fluid Coupling (e.g., Model 750 instead of the planned 560) with a specially engineered Extended Auxiliary Chamber.

The key to this solution was that the precisely calculated extended auxiliary chamber could provide a soft-start effect and torque-limiting characteristics similar to the dual-chamber structure during startup, fully meeting the core requirements of smooth equipment acceleration and overload protection. Ultimately, this proposal delivered significant benefits to the customer:

1.  Substantial Cost Savings: The manufacturing cost and price of a single larger-model Fluid Coupling with an extended chamber were significantly lower than those of the complex dual-chamber model.

2.  Enhanced Reliability: The simplified internal structure reduced potential failure points, improved overall equipment operational reliability, and lowered long-term maintenance costs.

3.  Fully Met Performance Standards: Actual operation verified a smooth startup curve and effective protection functionality, completely satisfying production process requirements.

This case perfectly exemplifies Mairuisheng's philosophy of "replacing over-engineering with precise calculation and creating optimal cost through innovative solutions"—a unique value proposition it is prepared to bring to international clients.

3. The Engineering Principle: Precision Over Presumption

This case study underscores a fundamental principle at Dalian Mairuisheng. The company approaches every hydrodynamic coupling application not as a simple component substitution, but as a unique system integration challenge. "Our process begins with data, not assumptions," explains a senior Mairuisheng application engineer. "We analyze the complete drive train dynamics. Often, a well-calculated modification to a robust, standard platform like our Fluid Couplings yields better performance and economics than opting for a more complicated, catalog-specified design. This requires deep mastery of hydrodynamic coupling characteristics across our entire size range, which is what our domestic experience has provided us." This analytical, value-driven approach is central to their service offering for global partners seeking to optimize capital expenditure (CapEx) and total cost of ownership (TCO) for their drive systems.

4. Commitment to Global Partners: Shared Expertise, Delivered Reliability

"Entering the international market is not merely about selling products," stated the Director of International Business at Dalian Mairuisheng. "We are committed to sharing the engineering experience and technical optimization capabilities validated in China's complex industrial landscapes. We believe that for global customers seeking reliability, economy, and customized support, our complete series of Fluid Couplings and Magnetic Coupling solutions, coupled with our engineering advisory service based on practical calculation, will be a highly competitive choice. The most important lesson from our 'extended chamber替代 (replaces) dual-chamber' case is that the best solutions often stem from a deep understanding of the customer's real needs and precise engineering practice. We are eager to build similar success stories with our new partners worldwide."
