H-type rotary joint, also known as cooling water rotary joint , is a series of products specially designed for cooling. It has the characteristics of small size, light weight, small friction torque, etc., and adopts flat sealing technology. Environment, choose various impregnated pairs of graphite, bronze, tungsten carbide, silicon nitride, which are enough to resist the influence of rust, scaling, debris and other impurities on the sealing surface. Our seals are on CNC machine tools and special grinding machines. The finished, mirror-like surface makes the seal more reliable, while also using high-precision rolling bearings to make it rotate smoothly.
H-type rotary joint is named because of its shell structure. H refers to the copper shell structure. Because h-type rotary joints are mostly copper shells, they are referred to as H-type rotary joints for short. According to the circulation method, it is divided into HD type unidirectional flow type rotary joint and HS type bidirectional flow type rotary joint . HS type two-way flow type rotary joint is divided into HS-G type two - way flow inner tube fixed rotary joint and HS-X type two - way flow inner tube rotary rotary joint according to the inner tube installation form. If the rotary joint outer tube and equipment journal The connection adopts flange connection , with suffix F, such as HS-XF40-20, HS-GF40-20, where 40mm refers to the nominal circulation diameter of the outer tube of the rotary joint is 40mm, and 20mm refers to the nominal circulation of the inner tube of the rotary joint. The diameter is 20mm. The connection between the outer tube of the rotary joint and the equipment journal is threaded , and there is no need to add a suffix, such as HS-X40-20, HS-G40-20, but the rotation of the outer tube of the rotary joint and the rotation of the equipment drum should be opposite. The tighter the thread, the tighter it becomes. )
