The two vacuum pumps can be started simultaneously or one pump can be started independently. The two vacuum pumps simultaneously suck and exhaust air, so that the air suction quantity can be increased, and when the two pumps work in parallel, the vacuum unit can be matched and operated at the working point with the optimal performance, thereby realizing the technical requirement of large air suction quantity. A clutch can be used for controlling the driving machine and the pump. The vacuum pump A and the vacuum pump B have the same rotation direction and are connected in parallel.

The vacuum pump A and the vacuum pump B are in the same rotation direction.
The two pumps can also be set to rotate in opposite directions, so that the two pumps are connected in series, when the two pumps work in series, a compound gas suction compression system is formed, which is equivalent to multi-stage compression, and the reasonable distribution of the system compression ratio under the high suction speed and the high exhaust pressure in the vacuum environment with the absolute pressure of 3300Pa can be realized; when the two pumps work in series, the exhaust port of one vacuum pump is communicated with the suction port of the other pump through a pipeline.
The beneficial effects of the invention are:
the vacuum unit can be matched and operated at the working point with the best performance, the technical requirement of large air extraction amount is realized, the overlarge outline size and the overlarge weight are changed into the normal size and weight, and the vacuum unit is suitable for normal transportation and installation. A clutch can be used for controlling the driving machine and the pump. When two pumps are connected in parallel to work, the air pumping quantity can be increased.
