Do you know what are the ways to fill the water pump? Let’s follow the editor of Д245 Water pump for a simple understanding!
1. Manual water filling method For small pumping stations with the inlet pipe diameter less than 300mm, the inlet valve usually has a bottom valve at the inlet of the inlet pipe. Usually, the manual water filling method is adopted, that is, charging is carried out from the special water filling vent hole on the upper part of the water pump housing. Fill the water funnel with water. For small pumping stations with an inlet pipe diameter of less than 300mm, the inlet of the inlet pipe is usually equipped with a bottom valve, or the pump can inject water from the outlet of the pump.
2. The self-stop water filling method uses the difference of water gas density and uses the principle of "water gas displacement" to realize the self-stop water filling method. This method removes the bottom valve of the pump. Design a gas container for an appropriate number of containers. Gas exchange tanks are usually plastic products or thin iron parts, and the cost is only half of the cost of the bottom valve. Then, the gas exchange box is placed at the water inlet of the water pump to form a communication body with the water pump and the pipeline. At the same time, the ventilation control valve is installed on the air flow channel between the ventilation box and the water pump. When filling water, fill the oil tank with water in advance, then seal the valve and open the gas exchange valve. After the ventilation is completed, close the ventilation valve, and a part of the water will be suspended in the inlet pipe. Repeat this method several times, the air will be completely emptied, and the water inlet pipe will be filled with water.
In summary, the editor of Д245 Water pump introduces: You can know a little about the filling method of water pump.
