Anti-High Frequency Interference Gas-Electric-Water Hybrid Slip Ring
45# Steel Air Shaft
Product Overview
This anti-high frequency interference gas-electric-water hybrid slip ring is specifically engineered for complex industrial environments with high-frequency electromagnetic interference. Featuring a composite structure of aluminum alloy shell and high-strength 45# steel pneumatic shaft, it integrates one pneumatic channel, two water channels, and twelve 5A electrical channels with targeted anti-high frequency interference treatment. Supporting speeds up to 250 rpm and maximum pressure of 1.0 MPa, it provides stable and reliable integrated gas, water, and electrical transmission for rotating equipment in harsh electromagnetic environments.
Key Features

Frequently Asked Questions
Q1: What specific measures are included in "high-frequency interference resistance"?
A: These mainly include: 1) Independent shielding of critical signal lines; 2) Optimized internal grounding to create a low-impedance interference return path; 3) Using electromagnetic shielding materials to isolate internal and external interference; 4) Filtering of input and output ports. These measures work together to ensure stable signal transmission within the typical industrial high-frequency interference band of 10kHz to several GHz.
Q2: Can the 12-channel 5A circuit be used to transmit high-frequency signals such as encoders?
A: Yes. Thanks to the anti-interference design, these channels are capable of transmitting high-frequency signals. For particularly sensitive differential signals (such as encoder A/B/Z), we recommend using twisted-pair shielded cables and specifying channels for targeted optimization.
Q3: Does the 45# steel pneumatic shaft require rust prevention treatment?
A: Yes. The 45# steel surface is nickel-plated or chrome-plated for rust prevention to cope with the potentially humid environment of the water channel. For special corrosive media, stainless steel pneumatic shafts can be customized.
Q4: Does the water channel support hot water or hot oil?
A: Standard seals are suitable for clean water or emulsions at temperatures ranging from 0-80℃. For high-temperature hot water, hot oil, or corrosive media, please provide the media type, temperature, and pressure parameters. We can then select appropriate high-performance sealing materials such as fluororubber and perfluoroether.
