JS-01 type Swivels are widely used in water, water filling and tunnel drilling, drilling can meet demand of 300 meters. JS-02 connector type water volume is small, reasonable amount of rotation consistent, high-speed cases, high stability, especially good sealing effect, to meet demand of 300-1500 meters drilling. JS-03-type water with JS-02 type connector advantage through high water to meet the 1000-2200 meters of coal drilling and drilling needs. JS-04 type of water connection for more than 110 large-diameter deep-hole drilling needs, Wenchuan Ke drill hole # 2 by I produced this model with good results.
