Oil and gas exploration equipment is an important part of China’s high-end equipment manufacturing industry. At the same time, slip rings are also installed in many places on the equipment in this field.As a professional slip ring manufacturer, JINPAT also often designs and manufactures corresponding slip rings for offshore oil and gas exploration industry equipment. In this article, we will deeply analyze what slip rings are used in the lower deck of oil and gas exploration equipment.

 

In the equipment industry, the equipment on the drill pipe usually needs to go down to the water thousands of meters deep in the sea. In order to meet the power output of the drill pipe, a high voltage of at least 2500V must be used to achieve the purpose of long-distance transmission. Slip rings similar to oil drilling platforms and deep-sea exploration robot control center slip rings used on oil and gas exploration ships also increase the rated working voltage of the slip rings to 2500V in order to ensure the power supply of underwater robots that go thousands of meters deep into the seabed.

 

Whether it is the slip ring of a deep-sea exploration robot or the slip ring on the drill pipe of an oil drilling platform, both are high-voltage slip rings, and both use carbon brushes and copper rings for contact; but the required rated current is very small. For example, the slip ring on the drill pipe of a drilling platform only has a current of 120A. the current path of the slip ring of a seabed exploration robot is only about 20A per circuit. So, are there any slip rings with higher voltage and larger current in the equipment of the oil and gas exploration industry? Yes, such slip rings are slip rings for pod-type electric thrusters.

 

Pod electric propulsion is commonly used in luxury cruise ships, scientific research ships, oil drilling platforms and other ship platforms. Why is it called a pod propulsion slip ring? Because this type of propulsion directly uses a motor to drive the propeller forward. The motor and propeller are hoisted and installed at the stern of the ship. The reason why it is called a rudder propeller is related to the ability of 360° wireless rotation given by the slip ring.

 

The slip rings installed on the podded electric propulsion system are usually rated at several thousand amperes to meet the high power requirements of the propulsion system. For example, the 3MW podded electric propulsion system slip ring developed by JINPAT has a designed rated current of 4000A.

In modern aerospace engineering, ensuring the safe operation of equipment is of vital importance. Recently, China’s commercial aerospace sector has once again become the focus due to a serious accident during the test run of the Tianlong-3 rocket, which has attracted widespread attention. This incident once again highlights the importance of key technologies in aerospace engineering. Slip rings, as a high-precision rotary joint device, have multiple functions and are widely used in aerospace, aviation, transportation, industry and other fields.In the future, with the continuous advancement of technology, slip rings will continue to develop in the direction of greater intelligence and efficiency, providing more advanced, high-precision and high-efficiency transmission solutions for various fields, especially playing a key role in ensuring the safe operation of aerospace equipment.

 

The Tianlong-3 rocket, the “protagonist of the accident” this time, was designed to support the construction of China’s satellite Internet constellation, and its technical specifications are comparable to those of the US SpaceX’s Falcon 9.This liquid carrier rocket with a diameter of 3.8 meters and a takeoff weight of 590 tons uses a parallel structure of nine TH-12 engines and liquid oxygen-kerosene propellant. It has excellent carrying capacity, making it one of China’s largest liquid commercial rockets.However, the occurrence of this test run accident revealed the lack of a technical detail: the lack of a steel cable restraint system. In rocket tests, the steel cable restraint system can effectively ensure the stability and safety of the rocket during the test run and prevent similar accidents from happening.As part of the cable restraint system, the slip rings played a key role by providing electrical connections and allowing the rocket to transmit data and power signals during the test run.

 

The application of slip ring technology in the aerospace field is not limited to the rocket test stage. Slip rings also play an important role in the actual launch process. For example, they play the role of bridging connection in the navigation, control and communication systems of rockets and spacecraft. Slip rings can transmit high-speed data, video signals and power to ensure the normal operation of various systems during flight. They are one of the indispensable technologies in the modern rocket launch process.

 

Therefore, it can be seen from the Tianlong-3 rocket accident that it is crucial to further strengthen the research and development and application of slip ring technology. In the future, with the rapid development of China’s commercial aerospace industry, technological innovation and safety management will become key factors in promoting the continuous progress of the industry. By improving and perfecting slip ring technology, the safety and efficiency of rocket testing and launch can be improved, laying a solid foundation for the long-term development of China’s aerospace industry.

 

In summary, the reflection triggered by the Tianlong-3 rocket accident is not only a warning for safety management, but also a reflection on the application of key aerospace technologies. In future aerospace projects, the advancement of slip ring technology will bring more stable and reliable support for rocket launch and operation, and promote China’s commercial aerospace to new heights.

The application of JINPAT slip ring in projectors is mainly reflected in its unique performance and technical characteristics, which can ensure the uninterrupted transmission of power and optical fiber signals when the projector is rotating at 360 degrees. The following is a specific analysis of the application of JINPAT slip rings in projectors:

 

1, to solve the winding problem: the projector needs to achieve 360 degrees of rotation in the work to provide multi-angle projection effect. However, the traditional cable is prone to winding and breaking during the rotation process, which affects the normal use of the projector. As a precise power transmission device, slip ring can effectively solve this problem. Through its internal rotating interface, the slip ring enables stable transmission of electrical signals and energy, ensuring that no cable entanglement or breakage occurs during rotation of the projector.

 

2, high-performance transmission: JINPAT slip ring has the characteristics of small insertion loss, high revolution, no contact, no friction, etc., to ensure the high-quality transmission of power and optical fiber signals. This allows the projector to maintain stable performance during rotation without problems such as signal interruptions or distortion.

 

3, widely used: the application of slip rings in projectors is not limited to general display occasions, but also widely used in high-end robots, remote control systems, radar antennas and other fields. In these fields, the slip ring can also play its unique performance advantages to provide reliable support for the stable operation of various rotating equipment.

 

4, installation and maintenance: Although the installation and maintenance of the slip ring requires a certain amount of professional knowledge and skills, by following the correct installation steps and precautions, you can ensure the stable operation of the slip ring in the projector. At the same time, regular maintenance and inspection can also find and solve potential problems in time to extend the service life of the slip ring.

 

In summary, the application of JINPAT slip ring in projector not only solves the problem of winding, but also provides high-performance transmission and a wide range of application scenarios. With the continuous development of technology, JINPAT slip rings will be more and more widely used in projectors and other fields.

The 2024 Paris Olympics is about to be held, and there will be an opening ceremony that will attract worldwide attention. In previous Olympic opening ceremonies, HDMI Slip Rings were used in cameras and stabilization equipment, as well as other types of Electronic slip rings including rotating stages.As a professional slip ring manufacturer with nearly 30 years of experience, JINPAT Electronics is paying attention to the advanced technical equipment that may be used in the Olympic New Media Center and other key venues, especially in the application of HDMI slip rings.

 

 

In previous Olympic opening ceremonies, the most impressive thing for people was the lighting ceremony.Taking the Beijing Winter Olympics as an example, after the ignition, the lit Olympic torch was installed in the middle of the snowflake sculpture and rotated continuously with the sculpture, while the snowflake sculpture was installed in the ribbon-shaped sculpture, and the ribbon sculpture rotated counterclockwise along with the base.In order to ensure that the Olympic torch burns brightly for 24 hours at night, A electronic slip ring needs to be installed under the torch sculpture.If the torch does not use hydrogen as fuel, then a Pneumatic Hydraulic Integrated Rotary Joint is required to transmit combustible gases such as natural gas and hydrogen.

 

Since this snowflake sculpture is integrated with LED lights, although there are many light groups, the total power is not large and the working voltage is not high.When designing the Conductive Slip Ring, two 15A current paths and one grounding path are designed to fully meet the power supply needs of the sculpture.Even if a backup path is added, only Two paths with the same current need to be added, which has little impact on the structure, cost, etc. of the conductive slip ring.

 

The design and manufacturing of the conductive slip rings used in the Olympic torch is not difficult. At present, most of the hundreds of conductive slip ring manufacturers in China have the ability to design such integrated rotary joints. As a long-established slip ring manufacturer, JINPAT Electronics naturally has the ability to design and manufacture such products.
