The pressurization capacity of screw pump

If the screw pump is used, it can have a wide pressure range, up to 345 bar. In high-pressure applications, internal leakage should be restricted. The required rotor helix and small operating clearance. In addition, as in the labyrinth sealing theory, it is required to have a large number of active seals between the outlet and the outlet. When the rotor size and outcome are given, increasing the number of active seals requires increasing the length of the conveying components. Here, in order to achieve high pressurization capacity, the length of the screw pump should no longer be considered as small.
