Abstract
The invention discloses a numerical control mixed transportation pump with a simplified function. The numerical control mixed transportation pump is of an outer circulation fan plug shielding structure. A pair of rotators are vertically arranged into a pump case; a side end surface of the pump body and the rotators form a sealed volume; when a spur gear pair drives the rotators to revolute at the same angular velocity in a reverse direction, the sealed volume is divided into upper and lower parts by mesh lines of the pair of rotators; an upper fan plug is largest in volume, and is subjected to liquid seal to form vacuum; liquid is absorbed from the upper inlet end of the pump body and the meshing is performed through the lower sides of the mesh lines, so that the volume of the part is squeezed, the liquid is discharged from the outlet end and the trapped liquid flows away from a gap. The numerical control mixed transportation pump with the simplified function, provided by the invention, has the characteristics that the motor direct driving and the motor loading are integrated into a whole, a shaft can not extend outside, and therefore, the pump generates friction to shaft-seal a device during operation, so that the liquid leakage can be avoided, oil supply is not required for the pump including the driving part; under the same flow, compared with other pumps, the pump disclosed by the invention has the high-efficient and energy-saving effects.
