离心泵的特点是，送液能力大，流量均匀，但产生的压头不高，且压头随着流量的改变而变化。离心泵适用于工业和城市给排水,如高层建筑增压送水,园林喷灌,消防增压,远距离输送,暖通制冷循环、浴室等增压及设备配套。
The characteristics of the centrifugal pump are that the delivery capacity is large and the flow rate is uniform, but the pressure head is not high, and the pressure head changes with the change of the flow. Centrifugal pumps are suitable for industrial and urban water supply and drainage, such as high-rise building pressurized water supply, garden spray irrigation, fire supercharging, long-distance transportation, HVAC refrigeration cycle, bathroom and other pressurization and equipment matching.
选用方法
Selection method
根据被输送液体的性质及操作条件确定类型；
The type is determined according to the nature of the conveyed liquid and the operating conditions.
根据流量(一般由生产任务定)及计算管路中所需压头，确定泵的型号(从样本或产品目录中选取)；
Determine the type of the pump (selected from the sample or product catalogue) according to the flow rate (usually determined by the production task) and the pressure head required in the pipeline.
若被输送液体的粘度和密度与水相差较大时， 应核算泵的特性参数：流量、压头和轴功率。
When the viscosity and density of the conveyed liquid is quite different from the water, the characteristic parameters of the pump should be calculated: flow, pressure head and shaft power.
选择离心泵时，可能有几种型号的泵同时满足在最佳范围内操作这一要求，此时，可分别确定各泵的工作点，比较工作点上的效率，择优选取。
When selecting a centrifugal pump, there may be several types of pumps that meet the requirements in the best range at the same time. At this time, the working point of each pump can be determined separately, and the efficiency of the pump should be compared and the best choice should be made.
另外，也要考虑离心泵厂家的技术水平，质量问题，更要结合自己的实际需求。注意这几点，一定可以找到满意的离心泵。
In addition, we should also consider the technical level of the centrifugal pump manufacturers, quality problems, and more should be combined with their actual needs. Pay attention to these points, it is sure that a satisfactory centrifugal pump can be found.
