1. In terms of installation technology, the water absorption pipeline requires severe sealing, and it cannot be leaked or leak. Otherwise, the vacuum of the water pump into the water inlet will be destroyed, reducing the amount of water out of the pump pump. Therefore, we must carefully do the interface of the pipeline to ensure the construction quality of the pipeline connection.

2. Determine the height of the pump device (that is, the suction). This height refers to the vertical interval from the water source water surface to the central line of the pump leaf wheel. It cannot be confused with the permission to suck the vacuum altitude. And it is determined by stopping experiments under the condition of regulating atmosphere and 20 degrees Celsius. It did not think about the water flow after the water absorption pipeline.

3. The height of the water pump device should be allowed to suck the vacuum height deducting the losses of the water absorption pipeline. The remaining local value is restrained to the practical terrain absorption height. The height of the water pump device cannot surpass the calculation value, otherwise, the pump will not be able to draw the water.

3. It should be pointed out that when the pump device location is different from the experimental conditions, if the water temperature of more than 300 meters above sea level or be pumped exceeds 20 degrees Celsius, the calculation value should be stopped to correct. That is, the atmospheric pressure at different altitude and the saturated steam pressure higher than the temperature of 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the saturated steam pressure can be negligible.

4. The size of the calculation value is the resistance of the resistance of the water absorption pipeline. Therefore, the shortest pipeline should be used to arrange, and the curved number accessories should be installed as little as possible. It can also be considered to be appropriately equipped with a large caliber water pipe to reduce the internal flow rate of the pipe.
