[ Instrument Network Instrument Development ] On May 17, the “Research on Online Measurement and Testing Technology for Charging Facilities†applied by the National New Energy Vehicle Storage and Energy Supply Product Metrology and Testing Center of the Metrology Institute of Anhui Province successfully passed the preliminary review of the strategic international science and technology innovation cooperation project. .
The project is based on the B/S structure to build a remote online measurement and test network platform for charging facilities. It is intended to solve the problem of data interaction, online measurement and test module design, and vehicle-mounted charging facility verification/detection system development. The final research goal is to develop an online measurement and test platform based on IoT charging facilities, including on-site measurement and test modules, data processing and communication modules, and develop two sets of vehicle-mounted charging facility verification/detection systems, which satisfy JJG 1148-2018 and JJG1149-2018. It also meets the requirements of the standard NB/T 33008.2 arrival acceptance inspection test project, and proposes international standard development plans for the online measurement method standards (procedures), AC and DC measurement test modules for charging facilities.
The project cooperates with the Hefei Institute of Material Science of the Chinese Academy of Sciences and a number of industry-leading new energy charging facilities companies. The implementation of this project will effectively promote the service platform of China's new energy charging facilities operators to the world, which is beneficial to China's new energy automobile industry. Develop in a healthy and orderly manner.

Hydraulic Support System Seals
Hydraulic support seal
The seal of the Saifu lever hydraulic support is composed of a sealing ring, a retaining ring, a guide ring and a dustproof ring.
Sealing ring:Prevent leaks. Used in the category of hydraulic supports: drum ring, composite seal, mountain ring, bud ring, O-ring, etc. Generally rubber, polyurethane material.
Used together with the sealing ring, it has the functions of anti-crowding, guiding and reducing wear. It is generally made of phenolic XII cloth, 45% copper powder mixed with filled PTFE and other materials.
Guide ring:
It is a part used on the jack piston or piston rod to support the movement of the piston or piston rod. It can prevent the piston or piston rod from direct contact and friction with the cylinder during the movement, and protect the cylinder and the piston or piston. The rod is not damaged. Generally, it is polyoxymethylene, polytetrafluoroethylene and other materials.
Dust-proof ring: the main function is to go out and reciprocate the piston rod to expose the impurities attached to the outer surface of the cylinder, so as to prevent impurities such as external dust from entering the inside of the sealing mechanism. Generally rubber, polyurethane and other materials.
