Vertical Mud Pump is how the transmission

Vertical mud pump is a centrifugal pump is to rely on the rotation of the impeller to obtain centrifugal force. Until the gas density reaches the working range of the mechanical vacuum pump and is drawn out, thereby gradually obtaining a high vacuum.
In the vertical mud pump body with the right amount of water as the working fluid. When the impeller clockwise rotation, the water was thrown around the impeller, due to the role of centrifugal force, the water formed a shape similar to the pump cavity close to the same thickness of the closed ring. The inner surface of the lower part of the water ring is tangent to the impeller hub, and the upper inner surface of the water ring is in contact with the tip of the blade (actually the blade has a certain depth of insertion in the water ring). At this point the wheel hub and the water ring between the formation of a crescent-shaped space, and this space is divided by the impeller and leaves the number of equal number of small cavity.
If the impeller of the lower 0 ° as a starting point, then the impeller in the rotation 180 ° before the small chamber volume from small to large, and the end of the suction port connected, then the gas is inhaled, when the suction end of the small cavity When the impeller continues to rotate, the small cavity from large to small, so that the gas is compressed; when the small cavity and the exhaust port is connected, the gas will be discharged outside the pump. In summary, the vertical mud pump is to rely on changes in the pump chamber volume to achieve aspiration, flexible shaft pump compression and exhaust, so it can be variable-volume centrifugal pump.

Vertical mud pump can be used for petroleum, chemical, machinery, mining, light industry, medicine and food and many other industrial sectors. In many industrial processes, such as vacuum filtration, vacuum diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing, vertical mud pump has been widely used. Can be extracted flammable, explosive gas, in addition to pumping dust, water gas, therefore, the increasing use of water ring pump.
