(1) If the existing pump type is not satisfied with the requirements of the fountain equipment to describe the flow and describe the head, the series, parallel and variable speed method can be selected.

Fountain pump selection is necessary to fit the fountain equipment description needs, including the fountain system to describe the flow needs and describe the needs of the head, as long as these needs are reached, the role of the description can be completed.

(2) The selected pump, its flow and head should be fundamentally common with the flow and head described by the fountain equipment, and when the operating point changes, the pump has been operating at a high efficiency scale, without cavitation or overload of the power machine.

¢Û The size and number of pumps are mutually restricted. Pump selection is large, the efficiency is high, the number of devices is small, equipment, civil engineering and management costs can be reduced accordingly; However, the number can not be too little, or a pump attack, the whole system has a great impact. Usually, it is appropriate to install 2~4 sets. When the system describes the flow is small, can also only set up 1 pump, but should be equipped with a satisfactory number of vulnerable parts. Sprinkler pumping stations usually do not have backup pumps.

(4) If there are several pump types that can satisfy the needs of the flow rate and the description of the head of the fountain equipment, the pump type with high efficiency, small supporting power, easy operation and repair, and small total investment of the fountain system should be selected.

¢Ý the pump of the same fountain equipment is as common as possible, so that :(1) easy to handle and parts replacement; (2) get used to automatic and semi-automatic control; (3) Make the pump room layout single.
