The rubber molding machine has a high rotation speed. Uninterrupted supply of air for rapid cooling through high-speed rotary joints. For example, in the case of high-speed rotation of the rotary joint, the uninterrupted supply air cooling solid joint leakage can not be achieved, resulting in insufficient pressure and reduced gas volume. Under automatic production conditions, the rubber product cannot be rapidly formed and forms waste. Therefore, the realization of uninterrupted supply is essential, and the requirements for the street are extremely high. Conventional products in China usually use O-rings and Grae ring seals. The solid temperature is too high. The equipment speed is higher than 120 degrees. The wear resistance of the sealing surface is reduced. It is usually not available for 1-3 months and must be replaced.
The rotary joint realizes high-speed and high-temperature conditions, and the joint life is extended by 2-3 times of the service life of the conventional product. The technical support is to adopt a full-rotation floating seal structure. The overall joint structure is a shell, a stainless steel multi-spring, and a sealing ring. Tungsten carbide sealing ring. Hollow shaft, static ring needle roller bearings. Achieve high-speed rotating stainless steel multi-spring, evenly arranged. Achieve more balanced pressure balance compensation. The seal ring forms a sealed environment between the casing and the hollow shaft, and the hollow shaft and the static ring are designed to have a unique rotation stop device. Efficient sealing when the joint is rotated at high speed
