Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of rotary joints, it is recommended to prioritize checking key technical parameters such as pressure rating, speed range, and medium compatibility to ensure compatibility with existing equipment or pipeline systems.
  • In different scenarios such as construction machinery or food processing, the sealing material and corrosion resistance of rotary joints need to be selected according to specific working conditions, such as special alloy materials that need to be considered in high-temperature environments.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to reduce procurement risks.
  • Multi type rotary joints are suitable for complex systems that require simultaneous transmission of multiple media. When purchasing, it is necessary to specify the number of interfaces and fluid types to avoid increasing costs due to design redundancy.

Knowledge Base

Q

When choosing a crane tube rotary joint, comprehensive considerations should be made from multiple aspects such as material, sealing performance, structural design, manufacturing process, applicable working conditions, etc. The following is a detailed introduction: 1、 Material selection Outer ring material: alloy steel is preferred to ensure structural strength. Inner ring material: Choose stainless steel or lined with polytetrafluoroethylene according to the characteristics of the medium. Stainless steel is suitable for most conventional media

Q

This article introduces the definition, classification, characteristics, and common drawing methods of rotary joints, and analyzes their advantages, disadvantages, and applicable scenarios with application examples to help readers gain a deeper understanding of the application of rotary joints.

Q

The black oil inside the machine rotary joint is usually lubricating oil, which reduces the degree of friction and wear of the rotary joint. During the operation of the machine, the high temperature and wear inside the machine are caused by the heat and friction generated by high-speed rotation, so the role of lubricating oil is very important. The black color of lubricating oil is caused by the mixing of metal wear and impurities such as dust inside the machine.
