The particles in the slurry processed by the gravel pump have larger diameters. When selecting a gravel pump, you should ensure that the particle size requirements that the gravel pump can pass.
The clearance between the nut and the impeller of the gravel pump can be adjusted, which improves efficiency and makes it easy to disassemble and assemble the impeller.
The current-passing parts are made of high-chromium alloy, which has high hardness, high strength and longer service life than cast iron.
A spare blade is used on the back of the impeller to reduce the pressure on the back, reduce the axial force, prevent some debris from entering the seal, and protect the seal from wear.
Gravel pump maintenance methods.
In order to reduce slurry leakage, the tightness of the packing should be adjusted at any time, the bearing water pressure and water volume should be met according to regulations, and the bearings should be replaced regularly.
When replacing bearings, make sure they are dust-free and clean.
During normal operation, ensure that the temperature is appropriate and that the elastic pads in the coupling are installed correctly.
Make sure the direction of the motor and pump is correct and that the gravel pump components and piping system are installed correctly and securely. Pay attention to the degree of wear of flow parts and maintain and replace them in time.
