I-1B Screw Pump
1-18 screw pump is a type of single screw delivery pump. Its main working parts are eccentric spiral screw (rotor) and screw lining (stator) with double line helicoids internal surface.
Its working principle is, when the motor drives pump shaft, screw not only rotates along with its own axial line, but also rolls along with the inside surface of lining, hence a sealing chamber is fonned up.
For every round of screw rotation, the liquid inside sealing cavity will move forward by a screw pitch. Along with the continuous drive of screw, the liquid will be spirally pressed from one sealing cavity into another, and finally extruded out of the pump body.
Screw pump is a late-model machine to deliver liquid, which is featured by simple structure, dependable service, easy operation and maintenance, continuously even liquid outlet, stable pressure etc.
All the metal parts in contact with the medium are made of quality acid resistant stainless steel, bushing made of nontoxic and tasteless rubber. Service temperature may be up to 120℃.
They are used to deliver food pulp, 10,000 Pa·s liquor slurry containing solid particles or rubber pieces, suspending liquid and other corrosive medium in the industries of foodstuff, metallurgy, chemical, dyeing and printing, papennaking, ceramics, etc.
