Product Description

The piston rod is an indispensable connecting element, flawlessly supporting the piston in its vigorous operational environment. Predominantly utilized within oil and cylinder motion systems, it represents a component consistently in motion, necessitating high technical precision. The quality of piston rod processing is pivotal, directly impacting the longevity and reliability of the entire mechanism. With rigorous processing standards, including a surface roughness of Ra0.4-0.8 μm, the piston rod demands the highest standards of coaxiality and wear resistance, ensuring consistent and superior performance.

 

At the core of its functionality, the piston rod acts as the indispensable link between the piston and the crosshead. It is responsible for transmitting the force exerted upon the piston, thereby driving its movement with unmatched precision and dependability.
Key standards and specifications for piston rods encompass:
(1) Ensuring robust strength, stiffness, and stability to endure the most demanding conditions;
(2) Superior wear resistance with exacting requirements on machining precision and surface smoothness;
(3) Ingenious design to minimize the impact of stress concentrations on its structure;
(4) Secure connections assured to prevent any loosening over time;
(5) Thoughtfully engineered for easy disassembly and reassembly, enhancing maintenance efficiency.

 

 

Wenzhou Jianqing Industrial Company Strategically nestled in the south Zhejiang Marine Economic Development Zone (Oujiang Estuary), our location is a beacon of national recognition, nurturing a cutting-edge industrial ecosystem.
With a legacy of unmatched excellence since 1977, our illustrious history unfolds over three transformative growth phases: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). Our journey commenced in 1976, under the visionary leadership of Chen Jianqing and his dedicated colleagues, who embarked on a mission to produce superior quality valves. Despite initial challenges, they successfully delivered their debut valve batch under daunting processing conditions, securing a robust financial foundation for the company. By 1977, driven by a relentless pursuit of excellence, they collaborated with the Longwan school office, establishing the pioneering Wenzhou Tianlong Petrochemical Machinery Factory, specializing in sealing rings. The early years posed challenges of a basic product framework and undeveloped technical skills, yet the founders exhibited remarkable resilience, innovatively overcoming production and sales challenges with tenacity and ingenuity.
By 1979, driven by an ambitious vision for growth, the company expanded its product portfolio beyond initial sealing components, venturing into air valves, packing parts, pistons, piston rods, connecting rods, and bearing bushings. In 1984, the enterprise proudly transitioned into the private sector, becoming the Wenzhou Air Compressor Valve Factory, achieving the distinction of being Wenzhou's inaugural manufacturer dedicated to compressor components.
In 1990, our innovative products gained widespread market acclaim, propelling us into the esteemed circle of designated production enterprises under the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). We earned the privilege of joining China National Gas Corporation's refining and chemical spare parts network, becoming integral to the spare parts resource market of China Petrochemical.
The strategic shareholding reform in 1992 catalyzed our rebranding to Wenzhou Jianqing Industrial Company, marking a pivotal shift in our organizational journey.
As the new millennium dawned, we embraced a culture of relentless innovation, advancing from import imitation to pioneering independent design and research and development. Through progressive strides, we have firmly established our leadership within the industry.
Introduction to our diverse product categories: Jianqing Industrial proudly offers core products featuring three major categories of wear-resistant components: air valves, piston ring support rings, and packing rings, alongside gas regulators (actuators) and check valves. Our design philosophy has evolved profoundly, particularly evident in our air valves, which have progressed from initial metal mesh concepts to a diverse array of structural types, including ring inclined, mushroom, and infinity valves.
Our esteemed and far-reaching clientele encompasses a broad and varied spectrum across the magnificent landscape of numerous Chinese provinces, showcasing our unparalleled reach and influence. 29cef8ca
