Introduction to Through-Hole Gas-Liquid Electrical Signal Integrated Slip Ring Technology

The gas-liquid electrical signal integratedslip ring is a common type of custom slip ring, and JINPAT currently offersnearly a thousand models of this type of slip ring to its customers. However,among these cases, non-through-hole products occupy a larger share, andthrough-hole gas-liquid electrical integrated models are relatively rare. Amongthe through-hole gas-liquid electrical integrated slip rings offered by JINPAT,there are also many models with large production quantities, among which theLPT080-0220-05S-01A is a representative example. This slip ring has a diameterof 80mm, with only 1 gas passage integrated into the gas-liquid module, whilethe electrical module includes 2 20A current and 5 signal passages.

In general, gas-liquid electrical sliprings with the same aperture or no aperture will not share the same spindle,and due to the significant internal structural differences between the twomodules, it is normal for the outer diameter of each module to differ as well.The LPT080-0220-05S-01A is a model with different outer diameters for thegas-liquid and electrical slip ring modules, with the electrical slip ringmodule having a diameter of 170mm and the gas-liquid slip ring module having anouter diameter of 154mm. This product is the largest customized gas-liquidintegrated slip ring in terms of production quantity for JINPAT, with largeannual shipments.

JINPAT also has multiple related cases ofproducts that integrate the electrical and gas modules on the same spindle,among which the representative product is theSPT060-0230-1625-0210-0605-02S-0301-E2-01A. This integrated slip ring has only1 gas passage in the gas-liquid module, and can be used to transmit compressedair at a maximum of 10 bar. The product's characteristic is that the electricalmodule has various current path specifications, including 30A, 25A, 10A, 5A,and 1A, and in addition to these current paths, the product's electrical modulealso integrates 1 Gigabit Ethernet and 2 ordinary signals. Generally speaking,the 1A current path in a hollow shaft slip ring also supports the transmissionof ordinary signals.

In the through-hole gas-liquid electricalintegrated slip rings offered by JINPAT, there is also a special type ofproduct in which the inner layer is an electrical slip ring module and theouter layer is a gas-liquid module. The representative model of this type ofproduct is the LPPL050-0610-24S-04A. The advantage of this structure is that itsaves axial space and supports the transmission of more gas-liquid passages,but the disadvantage is that it takes up a relatively large lateral space, ascan be seen from the dimensions of the LPPL050-0610-24S-04A, which has a heightof only 142mm, but an outer diameter of 234mm, which is much larger than a50-diameter hollow shaft slip ring. This characteristic makes this type ofthrough-hole gas-liquid electrical integrated slip ring particularly suitablefor installation in some special electromechanical equipment that requires alow center of gravity.
