What are the main components of centrifugal pumps?

<p style="text-align: justify;">1. If there is any small failure of the pump, remember not to let it work. If the packing of the pump shaft is worn out and added in time, if the pump continues to be used, the pump will leak.</p> <p>2. Strong vibration occurs during the use of the water pump, which must be stopped and checked, otherwise it will also cause damage to the water pump.</p> <p style="text-align: justify;">3. The water pump must pay attention to maintenance after use, for example, when the water pump is used up, the water in the pump should be cleaned, it is best to remove the water pipe and then rinse it with clean water.</p> <p style="text-align: justify;">4. The tape on the water pump should also be removed, and then rinsed with water and dried in a light place, do not put the tape in a dark and humid place. The tape of the pump must not be stained with oil, let alone apply something sticky to the tape.</p>

<p>1. Check whether all screws and nuts are loose.</p> <p>2. Change the oil of the gearbox once, and fill the gear oil to the center of the gearbox oil label.</p> <p>3. Check whether the coupling is clean and free of bruises, and check the concentricity of the coupling.</p>

<p style="text-align: justify;">The basis of pump selection shall be considered from the aspects of process flow, water supply and drainage requirements, and five aspects shall be considered from liquid conveying capacity, equipment lift, liquid property, pipeline layout and operating conditions.</p> <p style="text-align: justify;">1. The colloid mill flow is one of the important performance data of the pump.</p> <p style="text-align: justify;">2. The head required by the equipment system is another important performance data of the selected pump, which is usually used to select a margin of 5% to 10% of the pump magnification.</p> <p style="text-align: justify;">3. Liquid properties, including liquid medium name, physical properties, chemical properties and other properties, physical properties and temperature density D, C u viscosity, solid particle diameter and gas medium, etc., are related calculations for the total system.</p> <p style="text-align: justify;">4. The pipeline layout condition of the device system refers to the liquid conveying liquid at the liquid delivery height, such as the lowest level of the absorption side, such as the highest level of the discharge side length.</p> <p style="text-align: justify;">5. The contents of operating conditions, such as the operation of saturated steam force P of liquid, pressure PS at suction side, pressure vessel PZ at exhaust side, altitude, ambient temperature gap or continuous operation, and the position of pump is fixed or portable.</p>
