G-type single-Screw pump is a positive displacement pump, which relies on screw and bushing intermeshing in the suction chamber and the discharge chamber to produce volume changes to transport liquid. It is an internal mesh enclosed screw pump. The main working part consists of a bushing (stator) with a double-headed helical cavity and a single-headed helical screw (rotor) engaged with it in the stator cavity. When the input shaft drives the rotor through the universal joint to revolve around the center of the stator, the stator-rotor pair continuously mesh with each other to form a sealed chamber. The volume of the sealed chamber is uniformly and axially moved at constant speed, and the medium is transported from the suction end through the stator - The rotor is fed to the press-out end and the medium drawn into the closed chamber flows through the stator without being agitated and destroyed. G-type single-screw pump specifications are based on the nature of the liquid being transported and flow, pressure to determine, while the pump speed by the viscosity and corrosive liquid transport, as the main parameters to choose, in order to ensure reliable operation of the pump. Pump design speed for the transmission of water or water similar non-corrosive liquids allow the maximum speed, in actual use due to the nature of the media and life requirements are different, the selection should generally be lower than the design speed. For high viscosity and medium containing particles, the design speed of 1 / 2-1 / 3 or lower is generally used. Low speed is good for pump wear. However, the wear rate of the stator decreases after use. At this time, the speed can be properly increased , To compensate for the decline in traffic is also a policy.
