Three kinds of Screw Pump
. Single - Screw Pump
, double - Screw Pump
and three - Screw Pump
Among them, the Single Screw Pump
is mainly composed of a spiral rotor and a rubber stator, the motor drives the rotor to rotate, the rotor and the stator to form dynamic closed cavity volume, with spiral moving forward transmission medium to achieve the purpose of. But wear faster.
Double Screw Pump
is driven by a motor of a synchronous rotation gear, gear shaft drives two groups by two spiral synchronous reverse rotation, but also formed the dynamic volume cavity, but not between the spiral contact, there is a certain gap, so that the service life of the pump is very high. Wide application
Three Screw Pump
is a motor with a drive screw rotation, the main spiral with two with the driven screw reverse rotation, conveying medium, but because he is the main rod from the rod, wear. Generally used for conveying lubricating medium. But because it is close contact, closed effect is good, the output pressure is big.
Mainly used for conveying viscous medium, for example, all kinds of oil, viscose, etc.
Because the price is higher than the pump, so the application is relatively poor, and other aspects of the pump transport difficulties
