JMZ-TK Series
Robust and Durable, Undaunted by Harsh Environments — The Reliability Engineering of JMZ-TK Vibration Isolators
Any excellent engineering product must ultimately withstand the severe tests of real-world environments. For vibration isolators, they may need to operate stably for a long time under harsh conditions such as humidity, salt spray, high-low temperature cycles, and dust. From the very beginning of its design, Xi'an Hoan Microwave Co., Ltd. has taken "reliability" as the core gene of the JMZ-TK series friction damping vibration isolators.
Material-Level Reliability Assurance
Key components of the JMZ-TK, especially the friction pairs, are made of high-performance wear-resistant composite materials and special alloys. These materials have undergone rigorous screening and testing, featuring low creep, anti-aging, and corrosion-resistant properties. Even under long-term loads, they can maintain stable mechanical performance and precise friction coefficients. The housing and connecting parts are usually made of high-quality galvanized steel or stainless steel, and undergo multi-layer protection treatment, enabling them to easily meet IP rating protection requirements and effectively resist erosion from moisture and corrosive gases.
Structural-Level Reliability Design
The entire vibration isolator has a compact structure, with no complex moving joints or vulnerable flexible membranes, fundamentally reducing the risk of failure. Designers have fully optimized structural stress through finite element analysis, ensuring that no plastic deformation or damage occurs even under extreme loads. A unique locking mechanism prevents the vibration isolator from detaching from the equipment during transportation or installation, enhancing the safety of the entire system.
Process-Level Reliability Control
Xi'an Hoan has a comprehensive quality management system. Every process, from raw material warehousing to finished product delivery, is under strict control. Critical processes such as preload application for friction pairs and damping force calibration are completed by precision tooling and equipment, ensuring that every JMZ-TK vibration isolator leaving the factory has highly consistent and reliable performance.
