Shield slurry pumps generally use our G-type gravel pumps. 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 gravel pump can adjust the nut to adjust the impeller clearance, reduce loopholes, improve efficiency, and facilitate the disassembly and assembly of 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 must be adjusted at any time; the bearing water pressure and water volume must be met according to regulations. Replace bearings promptly. When replacing bearings, make sure they are clean. Ensure the temperature is appropriate during normal operation. Make sure the elastic pads in the coupling are installed correctly. Make sure the direction of rotation of the motor and pump is correct. Make sure the gravel pump assembly 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.
