In the process of using the rotary joint , it is affected by the outside and its own high temperature and high pressure, and a good seal is required to ensure normal and reliable operation. The so-called sealing means that there is no leakage at the joints and equipment connection ports, and the sealing parts are called seals. Improper use or aging can easily affect the sealing effect. After all, wear parts must be checked regularly in order to solve the problem in time.
Rotary joints require seals with long-lasting wear resistance, low friction resistance and stable friction coefficient. The rotary joint must be controlled within a certain pressure and temperature range. The sealing structure is simple and compact, easy to disassemble and inspect, and slow wear can be automatically compensated to a certain extent.
The two main requirements for purchasing a rotary joint are technical and economic requirements. Simply put, it means spending less money to buy cost-effective joints. The technical requirements for joints are more complicated, such as pressure, temperature, path and specification of rotary joints. Of course, different types of joints must be selected for different job requirements, as well as some special rotary joints, such as professional rotary joints in the printing and dyeing industry, and embedded rotary joints in continuous casting machines. Multi-channel rotary joints are required to transmit different media; if you think that domestic rotary joints cannot meet the requirements, you need to use imported joints, but foreign and domestic standards are different. It is recommended that you specify the specifications and requirements at the time of purchase, so as not to fail to install normally after purchase.
