From September 23 to 25, the first China (Zhengzhou) New Energy Vehicle and Smart Driving Summit sponsored by the Zhengzhou Municipal Government was held in Zhengzhou Zhongyuan International Expo Center. Geely Automobile, Haima Automobile, Zhengzhou Nissan, Yutong Bus and other domestic new energy vehicles Industry leaders have gathered to participate in the exhibition. A new style of cool and long-lived new energy vehicles attracted people to stop and watch. At this “exposition†known as the Zhengzhou New Energy Vehicle, it is not only the “eye-catching†cars that attract attention, but also the interpretation of the policy on the development of the new energy automobile industry. There are no lack of strong support measures, including "real money" economic subsidies and "special" policies in charging, parking, and traffic. Full promotion of key areas The Yutong Bus Company's pure electric passenger car technology ranks the world's leading position. Haima Motors, Shaolin Coaches, Zhengzhou Nissan and other companies have strong strengths in the research and development of new technologies such as vehicle control and system integration for new energy vehicles... in China's new energy vehicles Zhengzhou occupies an important place in the industry map. “Last year, Zhengzhou new energy vehicles produced and sold 21,600 vehicles, which accounted for 6.5% of the total domestic new energy vehicles.†Zhang Ji, deputy secretary-general of the Zhengzhou municipal government, said that recently, Zhengzhou City has launched a series of special vehicles to support the application and industrialization of new energy vehicles. The development policy is clear that by 2020, the production capacity of new energy vehicles will exceed 150,000, and it will strive to build Zhengzhou into an important R&D and production base for new energy vehicles in the country. While increasing production, it focuses on popularization and application. “For the next four years, Zhengzhou will fully promote new energy vehicles in key areas and strive to promote more than 35,000 units.†Liu Yanling, deputy secretary of the Zhengzhou Industrial and Commercial Committee Party Group, said that in order to accomplish this goal, new and updated buses in urban areas, Starting from this year, all new energy vehicles will be used; from 2018, all counties (cities) and airports will use new energy vehicles. Since 2016, the city's new parade taxis have all used pure electric vehicles. Since 2018, all government agencies and public institutions in the city have adopted new energy vehicles. By 2020, all new and updated sanitation vehicles in the city will use new energy vehicles. The city's 4A-class or above scenic area will use new energy vehicles by 2020. Purchase and use are subsidized “New energy vehicles can not only enjoy state, provincial and municipal subsidy at the time of purchase, but Zhengzhou City will also provide 'real gold and silver' subsidies during the use process,†said Chen Zhigang, deputy director of Zhengzhou City Finance Bureau. According to reports, for the new energy vehicles purchased by consumers, the city of Zhengzhou provides financial subsidies in accordance with the ratio of 1:0.6 of the central government's subsidies. For non-fiscal investment in new energy buses purchased by public transport companies, it is based on the central government subsidy standards. The provincial and municipal finances provide matching subsidies at a ratio of 1:1. For new energy passenger cars purchased and used by individuals and enterprises for rental and public rental, vehicle use subsidies will also be given, mainly for motor vehicle accident liability compulsory insurance premiums, road and bridge fees, charging fees, charging facilities and installation. In terms of fees, the subsidy standard is 1 million yuan for a pure electric passenger car and 0.5 million yuan for a plug-in hybrid passenger car. In addition, free parking fees are charged for public parking spaces for new energy vehicles. Construction of charging facilities crack promotion bottleneck Vigorously promoting the construction of charging infrastructure is conducive to solving the problem of charging electric vehicles and is an important guarantee for the development of new energy automobile industry. According to Zhang Hongxun, deputy researcher of the Zhengzhou Municipal Development and Reform Commission, this year Zhengzhou plans to build 5 city-replaceable power stations and 3000 charging stations. By 2020, the ratio of charging piles to electric vehicles will strive to reach 1:3, basically meeting the charging needs of about 100,000 electric vehicles. Among them, the ratio of public charging piles to electric vehicles is not less than 1:8, and the public charging service radius in urban core areas is less than 1 km. “Breaking the bottleneck in the promotion of new energy vehicles and strengthening the planning, design, and guidance of charging and replacing power infrastructure is an important part.†Liu Yanling said that in the future, 100% of newly-built residential parking spaces should be built with charging facilities or construction and installation conditions. Not less than 2% of the parking spaces should be built in parallel with the residential project to complete the charging facilities and achieve synchronous use. The proportion of parking spaces for new large-scale public buildings, such as shopping malls, hotels, hospitals and office buildings larger than 20,000 square meters, with parking facilities for building public social parking lots, or construction and installation facilities, shall be no less than 15% of the total parking spaces. , And the parking space for the simultaneous establishment of charging facilities is not less than 10% of the total parking space. The installed residential area and social public parking lots are installed at a rate of not less than 3% and 10% of the available parking spaces, respectively. Hydraulic Support System Seals Kits
Hydraulic Support System Seals Kits
The hydraulic support system used in mines is used to support equipment during the mining process of coal mines or other underground mines.

It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
