Product Description

Product Description

 

The importance of the bearing shell in the compressor, as a key lining material inside the bearing, is self-evident. They significantly reduce the friction between the shaft and bearings and lower energy consumption by using high-strength, wear-resistant materials and supplemented with special lubricating oil films. At the same time, the design of the bearing cleverly forms fine grooves between the contact surfaces, which can accommodate lubricating oil and constantly change with the rotation of the shaft, effectively reducing wear. In addition, the bearing shell also has excellent shock buffering ability, which can absorb and disperse the vibration generated by the compressor during operation, protecting the machine structure from damage. More importantly, the bearing can ensure the stability of the axial position, enabling precise control of axial displacement during machine operation and ensuring the long-term efficient operation of the compressor. In summary, the bearing shell plays multiple key roles in reducing friction, eliminating wear, buffering vibration, and maintaining axial position in the compressor, and is an important component for improving the service life and safety of the compressor

Company Profile

 

Wenzhou Jianqing Industrial Company Positioned strategically within the illustrious South Zhejiang Marine Economic Development Zone (Oujiang Estuary), Wenzhou Jianqing Industrial Company shines as a modern industrial powerhouse. It proudly contributes to the national initiative focused on fostering advanced industrial clusters, exemplifying modern ingenuity and innovation.
Established in the industrious year of 1977, Wenzhou Jianqing Industrial Company's illustrious journey is elegantly divided into three transformative phases. The journey began in Phase 1 (1976-1990), followed by Phase 2 (1992-2002), and culminating in Phase 3 (2002-2023). Guided by visionary founder Chen Jianqing and a devoted team, the company embarked on this ambitious venture in 1976, meticulously crafting valves under taxing conditions. This tenacious spirit blossomed with the delivery of their inaugural valve batch, securing essential capital. By 1977, the establishment of Wenzhou Tianlong Petrochemical Machinery Factory, in collaboration with Longwan School Office, marked a significant milestone. Initially, the focus was on crafting seal rings amidst complex production challenges, but the founders' determination overcame each obstacle, systematically resolving production and sales challenges to lay a robust foundation for future growth.
Driven by an unwavering pursuit of progress, by 1979 the company strategically expanded its product offerings. Shifting from a sole focus on sealing parts, they diversified into producing air valves, packing elements, pistons, piston rods, and bearing bushings. By 1984, the transition to private ownership led to the transformation into Wenzhou Air Compressor Valve Factory, establishing a pioneering presence as Wenzhou's first comprehensive manufacturer of compressor parts.
As the 1990s dawned, the market began recognizing the superior quality of their offerings. This recognition opened doors to the esteemed circle of designated production enterprises for the Petrochemical Industry Bureau (formerly the Ministry of Chemical Industry). They also became an integral part of China National Gas Corporation's refining and chemical spare parts network, as well as gaining entry into China's Petrochemical's spare parts resource market.
In 1992, a transformative era unfolded with a strategic shareholding reform, ushering in the official renaming to Wenzhou Jianqing Industrial Company. This pivotal shift marked the beginning of a new chapter characterized by growth and strategic realignment.
Post-2000, Wenzhou Jianqing Industrial Company embarked on a trailblazing journey of self-reinvention. Building on years of rigorous product refinement, they transitioned from initially emulating imports to innovating unique designs and spearheading independent R&D. Step by step, they have cemented their esteemed status within the ever-evolving industrial landscape.
Product category introduction: Jianqing Industrial proudly unveils a comprehensive selection of wear-resistant components that stand the test of time and performance. Our portfolio includes air valves, piston ring support rings, packing rings, gas regulators (actuators), and check valves, each a testament to our commitment to innovation and quality. Our design philosophy has seen groundbreaking advancements, especially in our air valves, which have undergone a remarkable transformation. From their initial metal mesh iterations, they have evolved into cutting-edge structures like ring inclined valves, mushroom valves, and our avant-garde infinity valves, setting new standards in the industry.
