| titleOfInvention | A vacuum oil pump protection device |
| abstract | The utility model discloses a vacuum oil pump protection device, comprising: a first connecting pipe connected with an air outlet of a device to be evacuated; a first cooling device is provided with a first opening into which the first connecting pipe extends; The device is also provided with a second opening for the first connecting pipe to extend; the filtering device is provided with a third opening for the first connecting pipe to extend into, and the upper part of the filtering device is provided with a fourth opening for the gas in the filtering device to flow out. an opening; a second connecting pipe communicated with the fourth opening, and the air outlet end of the second connecting pipe is communicated with the air inlet of the vacuum oil pump; and a second cooling device, the second cooling device is provided with a second connecting pipe extending into The fifth opening, the second cooling device is also provided with a sixth opening for extending the second connecting pipe. After the gas is initially cooled, filtered and cooled again, it enters the vacuum oil pump, which can keep the gas entering the vacuum oil pump free of substances that damage its internal parts, thereby effectively protecting the vacuum oil pump. |
