噴泉專用泵是噴泉工程中必須存在的一種噴泉設備，選擇合適的噴泉專用泵能使噴泉達到預期設計的效果。所以在噴泉專用泵的選擇上面有很多講究和注意疊浪噴泉工程廠家工程師王工為大家先整理一下噴泉專用泵的選型的原則
Fountain pump is a kind of fountain equipment that must exist in fountain engineering. Selecting suitable fountain pump can make fountain achieve the desired design effect. Therefore, in the selection of fountain pump, there are a lot of stress and attention to superimposed wave fountain engineering manufacturer Engineer Wang Gong for you first sorted out the selection principle of fountain pump.
1、所選定的噴泉專用泵，其流量和揚程應與噴泉系統設計流量和設計水頭基本一致，且當工作點變動時，泵始終在高效率范圍工作，不致產生汽蝕或使動力機過載。
1. The flow rate and head of the selected special fountain pump should be basically consistent with the design flow rate and head of the fountain system. When the working point changes, the pump always works in the high efficiency range without cavitation or overloading of the engine.
2、噴泉專用泵的大小和臺數是相互制約的。噴泉專用泵選得大，則效率高，安裝臺數少，設備、土建和管理等費用均可相應減少;但是，臺數又不能太少，否則1臺泵發生故障，對全系統影響很大。一般以安裝2~4臺為宜。當系統設計流量較小時，也可只設置1臺噴泉專用泵，但應配備足夠數量的易損零件。噴灌泵站一般不設置備用噴泉專用泵。
2. The size and number of special fountain pumps are mutually restrictive. If the special pump for fountain is selected large, the efficiency will be high, the number of installations will be small, and the cost of equipment, civil engineering and management will be reduced accordingly; however, the number of units can not be too small, otherwise one pump will break down, which will have a great impact on the whole system. Generally, it is advisable to install 2-4 sets. When the system design flow is small, only one fountain pump can be installed, but enough vulnerable parts should be equipped. Sprinkler pumping stations generally do not set up special spare fountain pumps.
3、如果有幾種泵型都能滿足噴泉系統設計流量和設計水頭的要求，則應選擇其中效率高，配套功率小，便于操作、維修，并使噴泉系統的總投資小的那種泵型。
3. If there are several types of pumps that can meet the requirements of design flow and head of fountain system, the pump type with high efficiency, low matching power, easy operation and maintenance, and low total investment of fountain system should be selected.
4、同一噴泉系統安裝的噴泉專用泵，盡可能型號一致，這樣：①便于管理和零件配換;②適應自動化和半自動化控制;③使泵房結構單一。
4. The special pump for fountain installed in the same fountain system should be of the same type as possible, so that: (1) it is easy to manage and replace parts; (2) it is suitable for automation and semi-automation control; and (3) it makes the structure of pump house single.
5、如果現有的噴泉專用泵型號不能滿足噴泉系統設計流量與設計水頭的要求，可采用串聯、并聯以及變速的方法解決。
5. If the existing type of fountain pump can not meet the design flow and design head requirements of fountain system, series, parallel and variable speed methods can be used to solve the problem.
6、盡可能選擇汽蝕性能好的噴泉專用泵，這對于簡化泵房結構、減少泵站投資、保證機組安全運行有很大影響。以選擇離心泵為例。如果所選泵的允許吸上真空高度值大，而水源水位變化又不大時，可采用簡易的、由磚木結構所組成的分基型泵房;反之就必須改用較為復雜的、由鋼筋混凝土與磚石混合結構組成的干室型泵房。
6. Choosing fountain pump with good cavitation performance as far as possible has great influence on simplifying pump house structure, reducing investment of pump station and ensuring safe operation of unit. Take centrifugal pump as an example. If the allowable vacuum height of the selected pump is large and the water level of the water source is not changed much, a simple and basic pump house composed of brick and wood structure can be used; otherwise, a more complex dry chamber pump house composed of reinforced concrete and brick and stone mixtures must be used.
7. Recommend the use of national and ministerial products and products and energy-saving products with national production licenses to avoid the use of obsolete products.
7、推薦采用國優與部優產品以及獲得國家生產許可證的產品與節能產品，避免采用淘汰產品。
7. Recommend the use of national and ministerial products and products and energy-saving products with national production licenses to avoid the use of obsolete products.
噴泉專用泵選型必須符合噴泉系統設計要求，包括噴泉系統設計流量的要求以及設計水頭的要求，只有達到這些要求，才能實現設計效果。
The selection of special pump for fountain must meet the design requirements of fountain system, including the design flow requirements of fountain system and the design head requirements. Only by meeting these requirements can the design effect be achieved.
