How to solve the problem of insufficient flow of melt pump or insufficient outlet pressure

Recently, we have often asked our customers to ask questions like this: how to solve the problem of insufficient flow of melt pump or insufficient export pressure?

Pipeline pump

(1) reason: insufficient inhalation. Solution: increase liquid level.

(2) cause: leakage of pump body or inlet. Solution: replace gasket, fastening bolt, repair.

(3) reason: medium viscosity is high, solution: reduce medium viscosity.

(4) cause: excessive axial clearance of the gear, solution: adjust the interval.

(5) cause: gear radial clearance or side clearance too large, the solution: replace the pump shell or gear.

(6) reason: inlet valve opening is not enough. Solution: increase valve opening.
