Notes on selecting special pump for music fountain

The fountain selected for music fountain construction is a special pump. The flow and head shall be consistent with the design flow and head of music fountain system. When the set value changes, the pump is always in the high efficiency working range, without cavitation or engine overload. The size and table number of music fountain special pump are mutually restricted. The special pump for fountain has large volume, high efficiency, few installation units, and corresponding reduction in equipment, civil engineering and management costs; however, the number of tables cannot be too small, and the failure of one pump has a great impact on the whole system.

Generally speaking, it is advisable to install 2-4 sets. When the design flow of the system is less than one hour, only one special pump for fountain can be set, but the quantity of wearing parts shall be sufficient. The pump station does not usually have a dedicated pump for the standby fountain. If there are several types of pumps that can meet the requirements of the design flow and head of the fountain system, the type of pumps with high efficiency, small power, convenient operation, convenient maintenance and less total investment should be selected. The fountain system is installed in the same fountain system, and the design conforms to the same model, which is convenient for management and spare parts. The self-adaptive automatic and semi-automatic control make the pump house structure single. The existing fountain pump model can not meet the requirements of design flow and design head of fountain system, and can be solved by series, parallel and variable speed.

It is very important to select the special pump with good cavitation performance as far as possible, which can simplify the pump house structure, reduce the investment of pump station and ensure the safe operation of the unit. Taking the centrifugal pump type selection as an example, the pump has high suction and low water level, which can be used in simple brick and wood structure. On the contrary, it is necessary to transform it into a more complex dry room pump house composed of reinforced concrete and masonry.
