Centrifugal Pump Volute With High Corrosion Resistance And Long Operating Life
Centrifugal pump volute, the main function of the volute is to collect the water flow from the impeller and keep the water flow velocity in the volute as a constant by the continuous increase of the cross section of the water to reduce the head loss. After the water is discharged from the volute, it flows through the pressure cone through the diffusion cone. The function of the diffuser cone is to reduce the velocity of the water stream and convert part of the kinetic energy of the water stream into pressure energy.
The slurry pump jacket is used on the pump body, and its function is mainly to protect the pump body from material damage, and to stabilize the operation of the equipment and prolong the service life. Usually, the material conveyed by the slurry pump contains solid particles of a certain size and some acid-base ions, so the sheath is subject to wear and corrosion of the slurry during use.
1 Wear: The relative movement speed between the solid ions and the overcurrent components in the slurry is large, the solid particles have continuous impact and wear on the surface of the flow parts, the surface of the flow parts is damaged due to tearing, and finally the overcurrent The component has been damaged.
2 Corrosion, the material conveyed by the slurry pump contains certain acid, alkali and salt ions, and corrodes the surface of the flow component through chemical reaction and electrochemical reaction during the transportation of the material.
3 Cavitation, due to uneven air pressure inside the slurry pump, a large amount of air bubbles are generated in a small air pressure in a small air pressure, and the air bubbles are shattered in a place with a large air pressure, and the liquid has a severe impact on the overcurrent components when filling the gap. Make it damaged.
4 All-purpose slurry pump guard plates are made of rubber. If the refrigeration system of the pump is not good, the guard plate will be damaged due to excessive temperature.
