Product Introduction
Farmland irrigation is an indispensable work in agriculture, especially in the season of lack of rain, this work is more frequent. In general, farmland irrigation is to pump water from rivers and canals to farmland for irrigation. Or under the rated pressure, delivery water to the air for spraying.
Generally, the head of the irrigation splitcase pump is within 30 meters, and under special circumstances, the pump with a height of more than 100 meters can be selected. The water output depends on the area of farmland, soil conditions and climate conditions. Customers need to determine the hourly water demand according to the actual working conditions.
Irrigation splitcase water pump is a kind of centrifugal pump. It produces centrifugal power by impeller rotating to work. There are many models to choose, and the range of flow and head to choose is also large. It is the most widely used pump in agriculture. Low head centrifugal pump can be selected in plain area, moderate head centrifugal pump can be selected in hilly area, and pump with high head can be used in high altitude area.
The selection of irrigation splitcase water pump
1. Determine the flow: flow = (total water demand of farmland + water loss of canal) / total time of pump working. The total water demand of farmland is equal to the product of farmland area and irrigation depth. When water flows through the channel, the water loss of the channel is also related to various factors. Generally, the loss of water pump is between 5% and 25% of farmland water demand. The working time of the water pump can be determined according to the actual needs.
2. Determine the head: the actual head can be measured in the field. That is the vertical height from the water source surface to the channel surface or farmland surface. If it is a river or a lake, the water level of the water source should be based on the low water level during drought resistance. When determining the head of water pump, the installation height of water pump should also be considered.
