带式输送机启动时间和输送带负荷启动的验算

Checking Computations about Starting Time and Starting with Burden about Belt Conveyors

带式输送机启动时产生的动张力将使带式输送机各部件的负荷显著增大,安全系数降低,从而影响带式输送机启动时的平稳性。对于大功率、长距离,高强度带式输送机,对启动时稳定性的要求越来越高。给出了带式输送机启动时启动时间和电机功率的验算方法。

Dynamic tensile force produced by belt conveyors started observably augments a burden endured by the serial parts of belt conveyors, safety factor is descended, and this will affect the calm of belt conveyors started. For the belt conveyors with high - power, long - distance and high - strength, the demand of the calm for belt conveyor started is higher and higher. Introduces the checking computation about the time of belt conveyors started and the power of the motor when belt conveyors are started.
