“The development of new energy will mainly focus on solar energy and nuclear energy.†Academician of the Chinese Academy of Sciences He Wei recently said in an interview with reporters that in the development of photovoltaic solar energy industry, the third generation of photovoltaic power generation technology will replace the first and second generations. He Yong believes that photovoltaic power generation technology should strengthen the construction of solar energy accumulation and storage bases on the water surface. “This is both inexpensive and affordable, and it can effectively avoid the occupation of cultivated land.†The third-generation photovoltaic power generation technology refers to the "solar-smelting silicon + tracking + spotlight + high-efficiency concentrating silicon battery", which is characterized by green, high-efficiency, low-cost, and long-life, in which "green" is the biggest advantage. The core of the “green†technology is solar silicon. Its characteristic is the use of solar energy. Although it is also high in energy consumption, it consumes not electricity, but solar energy. In this sense, the pollution caused by the third-generation photovoltaic power generation technology is basically zero. In nuclear energy, He Yong advocated the development of nuclear energy, but he did not approve of its development in the interior. "We hope that nuclear energy can also enter the sea. We can use nuclear energy to effectively arm our warships and naval forces with unlimited potential." For the development of electric vehicles, He Wei believes that: "Electric vehicles should focus on the development of small and medium-sized passenger and cargo electric vehicles that meet the needs of small and medium-sized towns and rural areas. The current reliable electric vehicles should be miniaturized and have a battery life of 120 kilometers or more. The maximum speed should be reached. More than 80 kilometers, vehicles capable of carrying 3 to 4 or 200 to 400 kilograms of cargo." According to He Ji, the rear electric vehicle may be in the form of a combination of a hub motor, an energy storage system, and a vehicle carrier. Among them, the hub motor can be standardized by an independent research institution, and the use of a hub motor can be used to disregard the complicated transmission system. Such electric cars can standardize the installation of power systems. If it is necessary to increase power, electric vehicles can be increased from 4 to 6 or 8 rounds. This can only be achieved by strengthening the chassis technology.
High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.
High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.
This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.
The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.
Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
