Driven gas-liquid separation starting device

A driven gas-liquid separation starting device, wherein a gas-liquid chamber, a primary gas-liquid separation chamber, a secondary gas-liquid separation chamber and a self-priming chamber are arranged in a housing and communicated in sequence, wherein

• the gas-liquid chamber is communicated with a pump channel, a rotation mechanism is arranged in the gas-liquid chamber, the rotation mechanism is driven by a mixed gas-liquid fluid in the pump channel to rotate;
• a second cam mechanism is arranged in the primary gas-liquid separation chamber, the second cam mechanism is connected to an output shaft of the rotation mechanism, the primary gas-liquid separation chamber is divided by a baffle of the primary gas-liquid separation chamber and the second cam mechanism into a plurality of primary gas-liquid separation units, a plurality of spiral gas-liquid separation mechanisms in contact with the second cam mechanism are arranged in each of the primary gas-liquid separation units, the spiral gas-liquid separation mechanisms are driven by rotation of the second cam mechanism to cut the mixed gas-liquid fluid;
• a first cam mechanism is arranged in the self-priming chamber, the secondary gas-liquid separation chamber is in contact with a rolling pair of the first cam mechanism through a supporting connecting rod, a volume of the secondary gas-liquid separation chamber is changed by rotation of the first cam mechanism, to carry out further gas-liquid separation on the mixed gas-liquid fluid with a high gas content obtained through separation in the primary gas-liquid separation chamber;
• and an exhaust chamber for exhausting gas is arranged on the self-priming chamber.
