Product Description

The piston rod is a vital connecting component that empowers the piston to perform its crucial work. Predominantly utilized in oil cylinders and cylinder motion execution components, it is distinguished as one of the most active and technically intricate moving elements. The caliber of processing for piston rods has a direct, impactful influence on the overall lifespan and reliability of the entire machinery. Processing requirements are meticulously high, with the surface roughness precision demanded at Ra0.4-0.8 μm, alongside stringent standards for coaxiality and wear resistance, ensuring impeccable performance and extended durability.

The pivotal role of the piston rod is to seamlessly connect the piston with the crosshead, effectively transmitting the forces exerted on the piston and enabling it to move with precision and efficiency.
Essential prerequisites for piston rods include:
(1) Robust strength, unwavering stiffness, and steadfast stability;
(2) Exceptional wear resistance complemented by high precision in machining accuracy and surface smoothness;
(3) Carefully designed to mitigate the adverse impacts of stress concentration on its structure;
(4) Assurance of a reliable, secure connection that prevents any potential looseness;
(5) A thoughtfully engineered design of the piston rod structure that simplifies the processes of disassembly and assembly.

Wenzhou Jianqing Industrial Company Strategically nestled in the heart of the south Zhejiang Marine Economic Development Zone (Oujiang Estuary), our prestigious location is celebrated nationally for fostering a pioneering industrial cluster.
Boasting a rich legacy of excellence since 1977, the illustrious history of our company is delineated by three distinctive growth phases: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). It all commenced in 1976 when visionary founder Chen Jianqing, with his determined companions, embarked on an ambitious journey to produce high-caliber valves. Despite an array of challenges, they successfully delivered their inaugural batch of valves under restrictive processing conditions, thus securing the company's foundational capital. By 1977, driven by an unwavering commitment to excellence, they collaborated with Longwan school office to inaugurate the groundbreaking Wenzhou Tianlong Petrochemical Machinery Factory, focusing on sealing ring production. Although the nascent years were marked by challenges due to simplistic product structures and nascent technical capabilities, the founders showcased extraordinary resilience and innovation in overcoming production and sales challenges.
In 1979, motivated by a forward-thinking vision for expansion, the company extended its product range beyond initial sealing components to encompass air valves, packing parts, pistons, piston rods, connecting rods, and bearing bushings. By 1984, the enterprise made a strategic transition into the private sector, rebranded as Wenzhou Air Compressor Valve Factory, proudly emerging as Wenzhou's pioneering manufacturer specializing in compressor components.
In 1990, our products achieved notable market recognition, empowering us to join the elite ranks of designated production enterprises of the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). We became esteemed members of the refining and chemical spare parts network of China National Gas Corporation, and an integral part of the spare parts resource market of China Petrochemical, marking an era of distinguished partnerships.
In 1992, an innovative strategic shareholding reform ushered in our rebranding as Wenzhou Jianqing Industrial Company, signaling a transformative shift in our organizational journey and setting a new trajectory of growth and success.
With the dawn of the new millennium, we embraced a culture of continuous innovation, evolving from import imitation to pioneering independent design and research and development. Through steady and strategic advancements, we have cemented our reputation and standing within the industry, propelling us towards future achievements.
Introduction to our vibrant product categories: At Jianqing Industrial, our core offerings feature three major wear-resistant components: air valves, piston ring support rings, and packing rings, complemented by gas regulators (actuators) and check valves. Our design philosophy has undergone significant transformation, notably in our air valves, which have progressed from initial metal mesh designs to a diverse array of structural types such as ring inclined, mushroom, and infinity valves, showcasing our commitment to innovation and versatility.
Our vast and diverse client base extends across numerous Chinese provinces, underscoring our extensive reach and influence within the industry. a2c60f24
