In the pump industry, "water diversion" refers to "water used for guidance".Because some pumps must manually add water before working to form a closed environment inside the pump. The movement of the internal parts of the pump causes partial vacuum, so that the external water can be pressed into the pump inlet by atmospheric pressure under the pressure difference between internal and external, and complete the water absorption.For example, the water pump used to be used in rural areas must be added to draw up water from the well.
Self-priming is mainly used in pumps and liquid pumps, and is a relatively important parameter.
In the pumping pipe of the pump, under the condition of air, the negative pressure (vacuum) formed when the pump is working is used to push up the water below the pumping port under the action of atmospheric pressure and then discharge from the drainage end of the pump.There is no need to add "water diversion" before this process.A pump of this capacity is called a "self-priming pump."
The height of imbibition is called "suction distance" and the unit is usually "meters".
Also known as "maximum self-priming height."That is, the pump can automatically draw water up the maximum height (pump pumping port is vertical to the surface to be pumped).All of our pumps are self-priming pumps, and the standard suction range refers to this situation.Some centrifugal pumps have no self-priming capacity and must be watered for the first time.Although some diaphragm pumps also have self-priming capacity, the "suction path" of the mark is often different from the vertical height under which the water can be pumped under "all air in the inlet pipe". Please note this point.
