The support sleeve on the top of the bearing pressure ring is used to support the filled sealing ring. The bearing pressure ring is made of special materials to reduce the friction between it and the hollow rotating shaft.

When the detachable water seal structure in the rotary seal connection device leaks, that is, the filling seal ring and the second O-ring are damaged, high-pressure water will enter the water-permeable chamber along the surface of the hollow rotating shaft, and pass through the water-permeable channel, ring The groove and the drip hole flow out of the casing; the high-pressure water seeps into the upper surface of the bearing pressure ring along the inner wall of the assembly hole, and then flows into the drip hole through the inner wall of the casing.

Turntable: It is used to install the manual seal adjustment mechanism, and to disperse the high-pressure water flow, and to carry out the rotary jet cutting operation driven by the driving motor;

By twisting the pressure cap, the pressure cap presses the pressure sleeve downwards, and the lower end of the pressure sleeve squeezes the soft sealing packing (soft sealing packing, commonly known as mud-like soft packing, is a new sealing packing synthesized from asbestos-free polymer materials. , the appearance is like clay with special plasticity), the soft sealing packing seals the outer surface of the pressure rod to avoid leakage of high-pressure water here;

The lower surface of the pressure pad is an upwardly concave spherical structure, which can improve the sealing effect on the jet hole;

The lower end surface of the pressure sleeve is a conical concave structure with a small top and a large bottom, so that when the soft sealing packing is pressed downward, the extrusion force on the soft sealing packing is directed towards the pressure rod, which fully improves the sealing effect.

Since the turntable needs to withstand the high pressure of high-pressure water, sufficient sealing is required. Therefore, a first sealing structure that is slidingly fitted with the first sealing adjustment block is provided on the first sealing box. The inner wall of a guide groove is respectively provided with a first anti-corrosion sealing gasket which is sliding and sealingly matched with the inner bottom surface of the turntable and the side wall of the guide rail, and a second sealing structure which is slidingly matched with the second sealing adjustment block is arranged on the second sealing box.
