We use pumps in many places, whether in production or in life, so you know that pumps are also capable.

Size, different pumps can do a different job. Today, we will see how the capacity of the pump can be identified.

The capacity of the identification pump mainly includes the flow and lift, and also the shaft power, speed and the necessary cavitation allowance. Is the amount of liquid flow through the pump outlet output refers to the unit of time, the general use of the volume flow; lift conveyor unit weight are liquid from the pump entrance to the export of energy increment, the volumetric pump energy increment is mainly reflected in the pressure increases, so usually in quantity instead of pressure to lift said. The efficiency of the pump is not an independent performance parameter, it can be calculated by other performance parameters, such as flow, head and shaft power. On the other hand, the known flow, lift and efficiency can also be used to calculate the shaft power. Health level self-priming pump

There are some interdependent and variable relations between the performance parameters of the pump. By testing the pump, we can measure and calculate the parameter values separately and draw them into curves. These curves are called the characteristic curves of the pumps. Each pump has a specific characteristic curve, which is provided by the pump factory. The performance section that is usually recommended is also marked on the characteristic curve given by the factory, which is called the working range of the pump.

The actual working point of the pump is determined by the intersection of the curve of the pump and the characteristic curve of the pump. To choose and use the pump, the working point of the pump should be set within the scope of work to ensure the economy and safety of the operation. In addition, when the same pump conveyed a liquid with different viscosity, the characteristic curve of the same pump would change. Usually, most of the characteristic curves given by a pump manufacturer are the characteristic curves of a clean cold water. For power pumps, with the increase of liquid viscosity, the lift and efficiency are reduced, and the shaft power increases. Therefore, sometimes viscous liquids are heated to make the viscosity smaller, so as to improve the efficiency of transmission.
