離心泵的特點(diǎn)是，送液能力大，流量均勻，但產(chǎn)生的壓頭不高，且壓頭隨著流量的改變而變化。離心泵適用于工業(yè)和城市給排水,如高層建筑增壓送水,園林噴灌,消防增壓,遠(yuǎn)距離輸送,暖通制冷循環(huán)、浴室等增壓及設(shè)備配套。
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.
選用方法
Selection method
根據(jù)被輸送液體的性質(zhì)及操作條件確定類型；
The type is determined according to the nature of the conveyed liquid and the operating conditions.
根據(jù)流量(一般由生產(chǎn)任務(wù)定)及計算管路中所需壓頭，確定泵的型號(從樣本或產(chǎn)品目錄中選取)；
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.
若被輸送液體的粘度和密度與水相差較大時， 應(yīng)核算泵的特性參數(shù)：流量、壓頭和軸功率。
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.
選擇離心泵時，可能有幾種型號的泵同時滿足在最佳范圍內(nèi)操作這一要求，此時，可分別確定各泵的工作點(diǎn)，比較工作點(diǎn)上的效率，擇優(yōu)選取。
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，也要考慮離心泵廠家的技術(shù)水平，質(zhì)量問題，更要結(jié)合自己的實(shí)際需求。注意這幾點(diǎn)，一定可以找到滿意的離心泵。
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.
