Product Description

At the heart of industrial machinery, the piston rod serves as a crucial connector that empowers the piston to perform its critical work. Primarily found in oil cylinders and cylinder motion components, these rods are characterized by their dynamic movement and the intricate technical demands they meet. The excellence of their craftsmanship not only enhances the lifespan but also bolsters the reliability of the entire machine they reside in. Piston rods are subject to exacting manufacturing criteria, including a surface smoothness requirement of Ra0.4-0.8 μm, coupled with stringent mandates for coaxial precision and impressive wear resistance.

The piston rod is a vital link that joins the piston and the crosshead, providing the necessary force transmission to propel piston movement.
Fundamental prerequisites for piston rods:
(1) Must possess ample strength, rigidity, and stability;
(2) Exhibit exceptional wear resistance and meet demanding standards for machining precision and surface finish;
(3) Architecturally designed to mitigate stress concentration impacts effectively;
(4) Guarantee a secure and steadfast connection to avoid any loosening;
(5) The piston rod's design should streamline both the disassembly and assembly processes of the piston.

Wenzhou Jianqing Industrial Company Nestled in the progressive south Zhejiang Marine Economic Development Zone at the Oujiang Estuary, our company enjoys a prime location renowned for fostering an innovative industrial cluster.
Boasting a legacy of excellence since 1977, Our journey unfolds through three remarkable phases: Phase 1 (1976-1990), Phase 2 (1992-2002), and Phase 3 (2002-2023). It all commenced in 1976 when our visionary founder, Chen Jianqing, set out with his dedicated partners to revolutionize valve production. Despite numerous hurdles, they remarkably produced their inaugural valve batch under constrained conditions, laying the financial groundwork for the enterprise. By 1977, driven by an unwavering commitment to quality, they collaborated with Longwan school office to establish the trailblazing Wenzhou Tianlong Petrochemical Machinery Factory, pioneering in sealing ring production. Although the early journey was marked by a simplistic product line and evolving technical prowess, the founders tackled production and sales challenges with resourcefulness and resolve.
In 1979, with an ambitious vision for growth, the company broadened its product scope beyond initial sealing components, incorporating air valves, packing parts, pistons, piston rods, connecting rods, and bearing bushings. By 1984, the enterprise had transitioned into a private entity, rebranded as Wenzhou Air Compressor Valve Factory, proudly establishing itself as Wenzhou's first specialized compressor components manufacturer.
By 1990, our products had garnered significant market acknowledgment, facilitating our inclusion among the designated production enterprises of the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). We earned esteemed memberships in the China National Gas Corporation's refining and chemical spare parts network and the China Petrochemical spare parts resource market.
In 1992, a pivotal shareholding reform catalyzed our transformation into Wenzhou Jianqing Industrial Company, marking a significant shift in our organizational journey.
As the new millennium dawned, we embraced a strategy of relentless innovation, evolving from import imitations to independent design and research. Our steady advancements have firmly established our industry stature.
Introduction to our product categories: Jianqing Industrial's flagship offerings encompass three core wear-resistant components: air valves, piston ring support rings, and packing rings, alongside gas regulators (actuators) and check valves. Our design philosophy has experienced remarkable evolution, particularly within our air valves, which have advanced from initial metal mesh designs to a diverse array of structural styles including ring inclined, mushroom, and infinity valves.
