In the use of vacuum pump unit in the process of automatic trip this situation is very troublesome, how to solve it, first we should understand the use of equipment, combined with other equipment to make a preliminary judgment, in order to find the cause of automatic trip.
Vacuum unit automatic trip reason 1: vacuum pump motor overload work. When the equipment is used, it 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 work overload after the pump starts, and the automatic trip will occur at this time.
The second reason for the automatic trip of the vacuum unit is that foreign matters and sundries fall into the pump cavity or pipe of the vacuum unit. The reason for the automatic trip of the vacuum pump unit is whether there are impurities, welding slag, small particles in the pipeline of the vacuum pump unit into the pump chamber.
The third reason for the automatic trip of the vacuum unit is that the vacuum oil of the vacuum unit is damaged. When the performance of vacuum pump oil is damaged, the vacuum unit will trip automatically. If the vacuum pump unit does not work according to the corresponding start-up and stop sequence or under the condition of automatic power-off, the working fluid of the water ring vacuum pump will return to the pump cavity under the influence of negative pressure, which will damage the performance of the vacuum pump oil, resulting in the overload of the equipment, exceeding the rated current and tripping.
The above is the common vacuum pump unit automatic trip problems and several common solutions, in the actual use process, to analyze the specific situation, combined with other equipment to determine the cause of automatic trip is the guarantee of high quality work.
