Introduction to JINPAT Gas-Liquid-Electric Integrated Slip Ring Technology

Gas-liquid slip rings and electric slip rings are commonly used products in industries such as automation. Some electromechanical devices require only gas-liquid slip rings, while others require only electric slip rings. However, there are often cases where integration of both is necessary. This is where gas-liquid-electric signal integrated slip rings come into play. JINPAT offers three main types of gas-liquid-electric signal integrated slip rings.

The first type involves directly connecting a standard gas-liquid slip ring and a standard electric slip ring using bolts. These integrated products offer high flexibility and do not require redesigning; only the procurement of two standard slip rings is needed. However, this solution is only suitable for relatively common and widely used electromechanical systems, making it less common.

Therefore, in most cases, gas-liquid-electric integrated slip rings require redesigning. This category can be further divided into two types: low-power electric slip rings integrated with gas-liquid functions, and high-power electric slip rings integrated with gas-liquid functions. JINPAT has extensive design experience in both of these product types.

Let's start with the low-power gas-liquid integrated slip rings. Representative models include LPPL120-02A-0402-E2, LPT000-0516-E2-02L, LPT000-1120-1202-02E2-02A, among others. Let's take LPPL120-02A-0402-E2 as an example. This slip ring is a hollow shaft slip ring with a large aperture, reaching a through-hole diameter of 120mm. It integrates 2 air passages, 4 routes of 2A electrical current, and 1 Gigabit Ethernet channel.

On the other hand, LPT000-0516-F2-02L and LPT000-1120-1202-02E2-02A are solid integrated slip rings. The former integrates 5 routes of 16A power rings, 1 Gigabit Ethernet channel, and 2 liquid channels. The latter integrates 11 routes of 20A, 12 routes of 2A electrical current, 2 Gigabit Ethernet channels, and 2 air passages. These products represent typical examples of gas-liquid, electrical, and signal integrated slip rings.

These products have limited volume and relatively low power transmission capabilities. For larger equipment, such as the gas-liquid-electric signal integrated slip rings used in fully rotating cabin-type electric propulsion systems, both power transmission capacity and weight are much larger than those of the aforementioned products. For example, JINPAT has developed a dedicated slip ring for a 3MW cabin-type electric propulsion system, which integrates 3 routes of 4000A high-current transmission, 72 routes of low-power signal transmission, 11 liquid channels, and 1 air passage.
