Parameters: maximum pressure: 1.6MPa maximum temperature: 280 ° C maximum speed: 40rpm Suitable medium: steam, thermal oil structural features: such products to adapt to the steam, and conducting oil are two different types of media, it is in addition to a similar Q-type rotary joint The performance characteristics of the internal structure follows the double ball seal to prevent internal leakage. And change the weakness of a single spring compensation pressure imbalance using rational design of combination spring compensating pressure uniformity, improved sealing performance.
