The utility model discloses a high pressure hydraulic rotary joint relates to electromechanical field field. This high pressure hydraulic rotary joint, including the adapter main part, top cap and taper plug, be equipped with annular filter screen on top cap, be equipped with movable spring on top cap, be equipped with taper plug on movable spring. This high pressure hydraulic rotary joint, through the setting of annular filter screen can in the process of oil delivery, can filter treatment to oil, like this can avoid the time of long -time use input oil, will have the precipitate of not preventing the situation that the plugging device leads to the stability of high pressure hydraulic rotary joint work, thereby ensuring that the hydraulic machine can be normal practicality, and through the setting of spacing round bar, can limit the side plate and spacing block, like this convenient the adapter main part and top cap separate, thereby convenient subsequent user to annular filter screen wash, remove the impurity in the adapter main part, ensure the use effect of adapter main part.

A high-speed hydraulic rotary joint includes a rotary inlet pipe and a bearing coaxially arranged with the rotary inlet pipe; the right end of the rotary inlet pipe is fixedly connected to the left side of the outer ring of the bearing, and a rotary outlet pipe is coaxially fixed to the right side of the inner ring of the bearing; a quick-release unit is coaxially arranged at the left end of the rotary inlet pipe, the quick-release unit including a rotary joint, a rotation limiting sleeve, and a translation limiting sleeve; the right end of the rotary joint is coaxially fixed with the rotary inlet pipe and its inner cavity is connected; a rotation limiting sleeve is sleeved on the outer side of the left end of the rotary joint, and a rotation limiting groove with an opening at the right end is formed axially on the cylindrical wall of the rotation limiting sleeve; a translation limiting sleeve is sleeved on the outer side of the rotation limiting sleeve. It is slidably connected to the rotating limiting sleeve, and the cylindrical wall of the translation limiting sleeve is inclined along the circumference with a translation limiting groove with an opening at the right end; the circumferential surface of the rotary joint is provided with a cylindrical limiting pin along the radial direction; the limiting pin passes through the limiting space formed by the intersection of the rotating limiting groove and the translation limiting groove; it can not only filter and clean the fluid medium in the high-speed hydraulic rotary joint and collect solid impurities in the fluid medium; but also cut off the unfiltered fluid medium from entering the equipment after the solid impurities in the filter unit reach a certain amount, and at the same time prompt the filter unit to be replaced to prevent solid impurities from entering the equipment through the fluid medium.
