The invention is mainly applied to the field of vacuum equipment and particularly relates to a novel vacuum compression system. The novel vacuum compression system comprises a motor. The motor is a double-shaft extension motor. One output end of the motor is connected with a vacuum pump A through a speed reducer A, and the other output end of the motor is connected with a vacuum pump B through a speed reducer B. The vacuum pump A and the vacuum pump B are both double-suction vacuum pumps. Air inlets of the vacuum pump A and the vacuum pump B communicate with air inlet pipes correspondingly. The two air inlet pipes communicate with a main air inlet of a vacuum system through an air inlet T-joint. Through the novel vacuum compression system, a vacuum unit can be made to operate at an optimum performance working point in a matched mode, and the technical requirements for the large air pumping amount are met. A driver and the pumps can be controlled through clutches. The air pumping amount can be increased when the two pumps operate in parallel. The compression ratio can be increased, and the air discharge pressure can be increased.
