The ejector can freely save the speed of the motor, which brings convenience to the scheduling, but each motor has its own natural frequency. It is assumed that the speed of the motor just meets the production request, but it is close to the natural frequency of the motor. Resonance will occur, causing severe damage to the motor. Therefore, it is necessary to consider avoiding the critical speed of the motor as much as possible while satisfying the production request.
Injector use: Firstly applied to various industries vacuum suction process: such as material absorption and transportation, condensation, distillation and evaporation, concentration, decolorization and deodorization, oxygen supply and oxygen removal, dry crystal filtration, chemical absorption, tail (waste) gas neutralization, Vacuum pumping, vacuum molding and other processes. Widely used in light industry, chemical industry, chemical, pharmaceutical, vacuum exercise, sugar, salt, monosodium glutamate, chemical fiber, paper, food, plastics, ceramics, large and medium-sized hospitals and factories and mines vacuum station, vacuum brick, building base Pit precipitation, drainage, petroleum, environmental protection and other industries.
