Being vacuum blower breakdown prediction manner and the vacuum blower breakdown prediction manner which predicts the breakdown of the vacuum blower

摘要

The vacuum blower breakdown prediction method of being possible to predict the breakdown of the dry vacuum blower, the vacuum blower breakdown prediction system, and the vacuum blower centralized monitoring system are offered. Vacuum blower breakdown prediction method when integral calculus value or mean value of electric current of the motor which turns the rotor of the vacuum blower exceed specified alarm setting value, decides the occurrence of breakdown, generates warning. It possesses with the rotor which revolution unrestrictedly is arranged inside the casing and the said casing, it sucks the vapor with the revolution of the said mo one evening and the rotor has the plural steps regarding the vacuum blower breakdown prediction system which predicts the breakdown of the vacuum blower which is spat out, ro one evening provides the pressure sensor between the steps. It does integral calculus value of electric current of the motor which turns the rotor, or the calculation of mean value when the said integral calculus value or mean value exceed specified alarm setting value, it can provide the breakdown prediction section which does the breakdown prediction of the vacuum blower. The breakdown prediction section changes breakdown prediction calculation method on the basis of the pressure value which is detected with the pressure sensor, or discontinues.
