The direct hydraulic oil rotary joint of the high-pressure cleaning machine is a rotary sealing device designed specifically for high-pressure hydraulic systems, mainly used for transmitting hydraulic oil media
The direct hydraulic oil rotary joint of the high-pressure cleaning machine is a rotary sealing device designed specifically for high-pressure hydraulic systems, mainly used for transmitting hydraulic oil media.
Core advantages
High voltage tolerance:
The working pressure can reach 35MPa, meeting the extreme working environment requirements of high-pressure cleaning machines
Adopting a balanced mechanical seal design to achieve pressure balance and ensure stable operation under high pressure
Excellent sealing performance:
Equipped with imported seals (graphite ring/silicon carbide mirror ring)
Multi stage O-ring combination structure effectively reduces sealing surface wear
Oil film sealing technology extends service life
High speed rotation stability:
The maximum speed reaches 8000rpm
Precision bearing support system ensures smooth high-speed operation
Structural design advantages:
Stainless steel shell, strong corrosion resistance
Split structure design for easy maintenance and replacement
The shell is equipped with oil injection nozzles and observation holes to support bearing lubrication and leakage monitoring

JD40 rotary joint is a key sealing component in industrial fluid transmission systems, usually referring to a rotary connection device with a diameter of DN40 (or corresponding British caliber). As a transitional sealing device that transports fluid media (such as water, steam, hydraulic oil, thermal oil, compressed air, etc.) from static pipelines to dynamic rotating or swinging equipment
