Pump parameters are stable depends on the efficiency of its own, some of the high efficiency of the pump, but some of the efficiency of the pump is not satisfactory. Today we introduced the water pump efficiency depends on what factors, we summed up the technical staff of a total of eight, make it clear of these factors we use water pump or water pump are a great help.
1 water pump itself is the most fundamental efficiency of the impact. Under the same working conditions of the pump, the efficiency may be a difference of more than 15%.
2 the running condition of the water pump is lower than the rated condition of the pump, the pump efficiency is low and the energy consumption is high.
3 motor efficiency in the use of basic remain unchanged. Therefore, it is important to choose a high efficiency motor.
4 the influence of the water pump efficiency is mainly related to the design and manufacture quality. Pump selected, the late management of small.
5 hydraulic loss, including hydraulic friction and local resistance loss. After running a certain period of time, the impeller and guide vanes inevitably lead to the surface abrasion, the hydraulic loss increases, the hydraulic efficiency is reduced.
6 water pump volume loss, also known as leakage losses, including the impeller seal ring, the class, the axial force balance between the three kinds of leakage loss. Volume efficiency is not only related to the design and manufacture, but also with the management of the late. After running for a certain period of time, due to the friction between the components, the gap increases, the volume efficiency decreases.
7 as the filter cylinder block, intake and other causes of pipeline centrifugal pump and idling.
8 water pump before the start, the staff do not pay attention to the centrifugal pump start the preparatory work before the heating pump, plate pump, infusion pumps and other basic operating procedures are not complete, often caused by pump cavitation, causing the pump noise, vibration, low pump efficiency.
