Recently, the Ministry of Communications issued the "Implementation Opinions on Accelerating the Promotion and Application of New Energy Vehicles (Draft for Comment)" (hereinafter referred to as the "Opinion Draft"), proposing that by 2020, the city of bus cities will add or update city buses and taxis. Among urban logistics distribution vehicles, the proportion of new energy vehicles is not less than 30%; the proportion of new energy vehicles in Beijing-Tianjin-Hebei region is not less than 35%. The application of new energy vehicles in the transportation industry has taken shape, with a total volume of 300,000 units.
In fact, before this, new energy pilot cities such as Beijing and Tianjin have introduced new energy vehicle promotion and application programs. These three areas will be the key directions for the promotion of new energy vehicles in the future. People in the industry said that the use of the public sector to promote new energy vehicles, whether in the preparation and implementation of supporting facilities, or the maintenance of equipment already in operation, has certain advantages over the private market.
Tianjin New Energy Bus "Great Popularity"
“This year, Tianjin Public Transport Group will use 'Building Green Bus' as the target of vehicle renewal this year. It plans to add and update more than 30% of the number of new energy bus operators in the bus operation vehicles.” General Manager Zhang Yaguang said that by 2015, Tianjin's pure electric bus promotion and application scale will reach 2,000. In accordance with the technical route of “recharging and replacing, adapting to local conditions, charging, charging, and changing”, this year the power company will build two power stations and increase 200 electric buses. At the same time, this year will also be charged according to local conditions. Station to meet the needs of Tianjin's development of pure electric buses.
The reporter also learned that according to the statistics of the Tianjin Science and Technology Commission, the city has already operated a total of 1,319 energy-saving and new-energy vehicles, operating 10 charging and replacement stations, and charging 471 charging piles. A total of 220 pure electric buses were operated in 8 bus lines in Tianjin. This year, we will strive to add 600 more pure electric buses, and the total number will reach 800. The postal express field actively promotes the replacement of motorized tricycles by new energy vehicles. At present, the mini-pure electric postal express vans developed by Qingyuan Company, a new energy vehicle company in Tianjin Binhai New Area, have entered the stage of large-scale production.
Public area "green light"
"As of now, we have helped nearly 650 vehicles in dozens of bus lines including Tianjin Binhai District use hybrid technology, and with the further clarification of the new energy vehicle promotion policy, the profit margin of the new energy vehicle industry will be Gradually released." Li Qiao, secretary of the Party branch of Tianjin Songzheng Electric Vehicle Technology Co., Ltd., told reporters that in recent years, with the rapid development of hybrid vehicle power systems, China's new energy vehicle-related industries have already had a certain market size. The cost of research and development of such automotive technology has also dropped significantly.
In addition to Tianjin Songzheng, new energy vehicles and key component companies such as Tianjin Qingyuan Electric Vehicle, Lishen Battery and Qifengtai Automobile Refit Co., Ltd. in Binhai New Area have also begun to accelerate the pace of industrial production. The 30 new energy express logistics vehicles developed and produced by Qingyuan Company have been delivered to Tianjin EMS, SF Express and other customers. At present, the production of new energy express vehicles has achieved large-scale production; the electric sanitation trucks produced by Tianjin Yufengtai Automobile Refit Co., Ltd. And electric postal vehicles have also been put into use...
The city's supporting facilities need to go first. "The development of new energy automobile industry should not only pay attention to the research and development of vehicle technology, but also pay attention to the coordinated development of various links in the industrial chain such as infrastructure construction and after-sales service system construction. Domestic promotion of new energy vehicles needs to realize the foundation of urban electric transportation. The integration of facilities will enable light rail vehicles, trolley buses and charging facilities in the city to be combined, and at the same time develop new wireless charging technologies, which should be used first in the middle of the city.” National “863 Program” Energy and New Energy Vehicle Major Projects The group leader Ouyang Minggao said that the urban network also needs to be combined with the new energy vehicle industry to establish a motorized intelligent transportation system, including vehicle data management system, traffic data management system, energy data management system, etc. These are the new domestic More critical aspects of the widespread promotion of the energy automotive industry.

HEATING INSULATION FOR BPHE

Heating insulation for a Brazed Plate Heat Exchanger is important to minimize heat loss and improve the overall efficiency of the system. Some common insulation materials used for this purpose include:
1. Mineral Wool: Mineral wool is a popular choice for insulation due to its excellent thermal properties and fire resistance. It is available in various forms, such as blankets or boards, and can be easily cut and shaped to fit the heat exchanger.
2. Foam Insulation: Foam insulation, such as polyurethane or polystyrene, is lightweight and offers good thermal insulation. It is often used in applications where space is limited or weight reduction is desired.
3. Fiberglass: Fiberglass insulation is widely used in industrial applications due to its low cost and good thermal insulation properties. It is available in various forms, such as batts or loose fill, and can be easily installed around the heat exchanger.
4. Ceramic Fiber: Ceramic fiber insulation is known for its high-temperature resistance and low thermal conductivity. It is commonly used in applications where the heat exchanger operates at high temperatures.
When selecting insulation for a brazed plate heat exchanger, it is important to consider factors such as the operating temperature, space limitations, and fire safety requirements. Additionally, proper installation and sealing of the insulation are crucial to ensure maximum effectiveness.
