Abstract
The invention discloses an internal exhausting liquid ring type self-priming centrifugal pump. An existing liquid ring type self-priming centrifugal pump is multiple in operation steps, and prone to causing leakage of transmission medium. The admission port of the internal exhausting liquid ring type self-priming centrifugal pump is communicated with the inlet of a pump body through a vane wheel rear cover plate upper through hole, a vane wheel inlet and a channel, and an exhaust port is communicated with the outlet of the pump body through an exhaust channel, an exhaust pipe and a gas-liquid separation chamber. When the internal exhausting liquid ring type self-priming centrifugal pump works, a liquid ring wheel induction chamber forms a vacuum pump to pump the gas in pipelines to the admission port, the gas in the admission port mixes with liquid and enters a liquid ring wheel, under the action of the high-speed rotation of the liquid ring wheel rotating, the gas-liquid mixture is enabled to flow to the gas-liquid separation chamber to achieve gas and liquid separation, the liquid flows back to a liquid storage chamber, the gas flows to the outlet of the pump, thus the process runs in cycle, the gas in the pipelines are discharged constantly until the liquid is sucked up, and a self-priming process is completed. The internal exhausting liquid ring type self-priming centrifugal pump is easy and convenient to operate, and media cannot leak.
