three-screw pump

1 Overview

The SN three-screw pump is a quantitative, low-pressure rotor pump that axially transports a certain lubricating medium without pulsation. It is suitable for transporting fuel oil, lubricating oil, hydraulic oil, mineral oil and other oils and lubricating fluid liquids.

2. Working principle

The conveyed medium must not contain any abrasive particles and substances corrosive to the pump material. The SN three-screw pump is composed of a special profile (cycloid) with a spiral profile. When the motor or the motor drives the active screw to rotate, the continuously moving sealed chambers gradually form a vacuum, and the liquid is sucked by the suction port under the action of atmospheric pressure It is conveyed to the discharge port continuously and without pulsation in the axial direction, without stirring or emulsification. The ability to form discharge pressure depends on the system load and the number of screw seal cavities, and also has a certain relationship with the viscosity of the conveying medium and the driving speed.

3. Product features
