JINPAT Pneumatic and Hydraulic Integrated Slip Ring Technology Analysis

JINPAT has been deeply involved in the slip ring industry for nearly 30 years and has long possessed the technical strength to independently develop pneumatic and hydraulic integrated slip rings. In the field of pneumatic and hydraulic integration, JINPAT has mastered several key core technologies, capable of providing various new technical solutions such as integrating pneumatic, hydraulic, and other signal modules to meet the demands of new conductive mechanical equipment.


Among numerous types of slip rings,pneumatic and hydraulic slip rings are relatively unique in function. They are typically used for the transmission of gases and liquids, providing raw material supply, equipment cooling lubrication, and equipment driving power to application terminals. Generally, pneumatic and hydraulic slip rings are integrated into other types of slip rings. The LPPL000-36A-0106-1502-0301-E2slip ring is a multifunctional pneumatic and hydraulic + electric + signal combination slip ring. Its pneumatic and hydraulic slip ring module features 36air passages, with a total length of 842mm and a maximum diameter of 220mm,with pneumatic pipes of G3/8″ specification at P10mm.


The main materials of pneumatic and hydraulic slip rings are metal, primarily lightweight aluminum alloys and various grades of stainless steel. Aluminum alloy pneumatic and hydraulic slip rings have unique advantages in light weighting, but their pressure tolerance is lower compared to stainless steel, so they are generally used more for transmitting air or liquid media within a certain pressure range. On the other hand, stainless steel pneumatic and hydraulic slip rings far exceed aluminumalloys in hardness and other aspects, so pneumatic and hydraulic slip rings on the market that can withstand higher pressures are mostly made of stainless steel. JINPAT also develops high-pressure-resistant pneumatic and hydraulic slip rings using stainless steel materials.


The difference in materials determines the different pressure tolerances of pneumatic and hydraulic slip rings. Therefore,when in use, pneumatic and hydraulic slip rings should operate within their designed pressure ranges. If the pressure of the transmitted gas or liquid exceeds the designed pressure tolerance of the pneumatic and hydraulic slip ring, it may lead to damage and pose safety hazards, which is one of the important precautions for using pneumatic and hydraulic slip rings.


The service life of pneumatic and hydraulic slip rings is also influenced by the chemical properties of the transmission medium. Generally, the chemical properties of compressed air, water,lubricating oil, and coolant are relatively stable and will not corrode the interior of aluminum alloy or stainless steel pneumatic and hydraulic slip rings. In some cases of JINPAT, some customers use pneumatic and hydraulic slip rings to transmit corrosive liquids. During later maintenance, a large amount of rust residue is cleaned from the interior, which affects the smooth rotation of pneumatic and hydraulic slip rings and shortens their lifespan, even leading to scrapping.
