Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
A transportation vehicle driven by a traction motor using electrical energy as the driving force. Common electric vehicles mainly include railway mainline electric vehicles, subway electric vehicles, urban trams (including trams or trolleys), light rail electric vehicles (also known as express trams), and so on. In addition, there are maglev electric vehicles, battery electric vehicles, and inertia flywheel electric vehicles. Common electric vehicles (such as trams, subway electric vehicles, etc.) use electricity from overhead contact networks or third rails, which are introduced into the vehicle through different forms of current collectors. Then, depending on the current system of the power supply and the nature of the traction motor, the electricity is either reduced through transformers, transformed through power converters, or both, like AC electric locomotives, and finally sent to the traction motor to drive the vehicle. Battery electric vehicles and inertia flywheel electric vehicles do not have an external contact network. The former relies on batteries to provide electrical energy and achieves short distance operation through traction motors; The latter relies on external power input to drive a huge inertia flywheel to rotate at high speed during vehicle parking at the station, accumulating energy. Then, the kinetic energy of the flywheel is used to drive the vehicle for short distance operation. These two types of electric vehicles, due to their lack of contact network, are beneficial for maintaining the neatness and aesthetics of urban streets when used in cities. In special occasions where explosion-proof measures are needed, they can also play their spark-free characteristics. Magnetic levitation electric vehicles rely on strong electromagnetic attraction or repulsion to levitate the vehicle on specific tracks, and are then driven by linear motors (including asynchronous or synchronous motors) to operate, and speed regulation is achieved by changing the input frequency of the motor. Its speed can be as low as that of ordinary urban trams, or it can reach a super high speed of over 500km/h. Magnetic levitation electric vehicle is a newly developed and technically challenging electric vehicle
