In the production process of using vacuum unit, how to solve the problem of automatic trip of vacuum unit? First of all, we need to understand the use of the vacuum unit, and make a preliminary diagnosis to determine the cause of the automatic trip of the vacuum unit. Vacuum unit automatic trip reason 1: vacuum unit motor overload work Roots vacuum pump is a booster pump, which can not be used alone, because it needs the combination of the front pump and the vacuum unit. When the vacuum does not reach a certain degree, the motor will overload after the roots pump is started, and the automatic trip will occur at this time. The second reason for the automatic trip of the vacuum unit: foreign matters and sundries fall into the pump cavity or pipe of the vacuum unit The reason for the automatic trip of the vacuum unit is whether there are impurities, welding slag and small particles in the pipeline of the vacuum unit into the pump chamber. The second reason for the automatic trip of the vacuum unit is that the vacuum oil of the vacuum unit is damaged When the performance of the vacuum pump oil of the vacuum unit is damaged, the vacuum unit will trip automatically. If the roots water ring vacuum unit does not work according to the corresponding start-up and stop sequence or under the condition of automatic power failure, the working fluid of the water ring vacuum pump will return to the cavity of the roots pump under the influence of negative pressure, which will damage the performance of the vacuum pump oil and cause the roots pump to overload and trip when it exceeds the rated current.
