Mechanical equipment is composed of metal or other materials, by several parts assembled, in one or more power drives, which can complete the production, processing, operation, and other functions or utility device. Electrical equipment is divided into high voltage electrical equipment and low voltage electrical equipment according to voltage grade.
Dynamic machinery converts existing mechanical or other nonmechanical energy into available mechanical energy. Power machinery includes wind machinery, hydraulic machinery, thermal engine (gasoline engine, diesel engine, gas engine, steam turbine), electric motor, pneumatic motor, hydraulic motor, etc.
Energy conversion machinery that converts mechanical energy into some nonmechanical energy or USES mechanical energy to do a particular job. Energy conversion machinery includes a generator, heat pump, hydraulic pump, compressor, etc.
TradeAider will check the products based on common quality standard and customer requests, including but not limited to sampling inspection, graphic evidence, and quality report, and in the meantime keep all the inspection records block-chained and publicly notarized.
