Description

Technical Field

[0001] The present invention relates to a friction testing system and method for a data center, an energy storage system and a supercharging system. Background Art

[0002] Data centers are the core of modern information technology infrastructure, containing a large number of servers and storage devices for processing, storing and transmitting large amounts of data. Servers are one of the most critical components in a data center, responsible for running applications and services.

[0003] The new power system based on new energy is becoming an important choice for sustainable energy development. With the rapid development of new energy technology, the application of energy storage system is becoming more and more extensive.

[0004] Supercharging technology is a fast charging technology that can quickly inject electrical energy into the battery of an electric vehicle by providing higher current and power, thereby shortening the charging time and improving the charging efficiency. Compared with the traditional slow charging method, the main purpose of supercharging technology is to fully charge the battery of an electric vehicle in the shortest time, greatly increasing the range of the electric vehicle.

[0005] Data centers, energy storage, and supercharging systems generate a lot of heat when processing high-load tasks, so heat dissipation is an important issue in data center design and operation and maintenance.

[0006] In the prior art, data centers, energy storage and supercharging systems generally dissipate heat through refrigerant media. Only at this stage are fluorine pump air conditioners used for thermal management. However, the service life of the friction pairs of fully enclosed fluorine pumps cannot be predicted, resulting in a large amount of cost waste in long-term operation testing. Summary of the invention

[0007] The purpose of the present invention is to provide a technical solution for a friction testing system and method for a data center, energy storage and supercharging system in view of the deficiencies in the prior art. The system can not only detect the wear of the friction interface on the rotating table, but also predict the service life of the coating on the metal surface and the cold medium. At the same time, the amount and pressure of the cold medium entering the rotating table are adjusted by the expansion valve to realize the gas-liquid two-phase conversion process during the operation of the gas and liquid simulated fluorine pump. The implementation method of the friction testing system has simple steps, which can not only meet the recycling requirements of the cold medium, but also control the amount of the cold medium when entering the rotating table. At the same time, the system operation cycle can be predicted according to the collected data to ensure the safe and efficient operation of the system.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The pump body, the pump cover and the fixed frame are connected to form a closed structure. The rotating cover is connected to the output shaft of the motor and is limited within the closed structure. Through the design of the closed structure, not only can the leakage of the refrigerant medium be prevented, but also the stable rotation of the rotating cover can be ensured to reduce resistance.

[0021] Furthermore, a first magnet is distributed in a ring shape on the inner wall of the rotating cover, which is used to drive the second magnet to rotate synchronously. A third magnet is provided on the inner wall of the rotating cover, and the third magnet is close to the fourth magnet, which is used to generate magnetic force to realize axial force on the rotating body.

The magnetic force generated by the first magnet drives the second magnet and the entire rotating body to rotate synchronously, so that the friction interface generates rotational friction;

[0027] S4. Then, the third magnet generates magnetic force to apply axial force to the rotating body, and the temperature, pressure and vibration parameters of the friction interface are detected by the sensor to achieve temperature control of the refrigerant medium, and the friction wear is predicted based on the parameters.

The magnetic force generated by the first magnet 17 drives the second magnet 18 and the entire rotating body to rotate synchronously, so that the friction interface generates rotational friction;
