3GB asphalt triple screw pump is rotor type positive displacement pump, it is to use screw meshing principle, rely on the rotation of the screw in the pump set inside mesh with each other, the conveying medium closed in the gear cavity, along the screw axial continuous uniform to push to the outlet for the system to provide the stable pressure.
It is made of cast steel and has two kinds of insulation and no insulation. It is recommended that the high viscosity medium adopts the screw pump with thermal insulation structure. If the user has special requirements, it can be made to go left and right.
1. Since the rotating element has only three rotors, is relatively small and rotates by liquid pressure, it ensures natural, smooth and quiet operation even at high speeds and pressures.
2. The liquid is enclosed in a chamber sealed by the rotor and sleeve and proceeds continuously from suction to discharge without pulsation or agitation.
3. Internal leakage losses are also low through precision machining of the rotating elements.
4. Since the liquid is continuously conveyed in the direction of thrust without agitation and the sealing chamber operates as an infinite piston, high suction ranges can be easily ensured without cavitation.
5. Small internal space of the rotating element.
6. Direct connection to motors and turbines is possible without reduction.
