Before starting the stainless steel vacuum pump, the pump and the intake pipe should be filled with water, otherwise the pump can not lift water. Sometimes we may have some water in the pump because of the last use, but it is not enough for this use. At this time, we need to fill it with water. What is the method?
1. Artificial filling method for small pumping stations whose diameter of intake pipe is less than 300 mm usually has a bottom valve at the intake pipe. Generally, artificial filling method is adopted, that is, the water filling funnel (or an inverted ordinary bottle without the bottom of the bottle) fills the water from the special filling vent on the upper part of the pump shell.
2. Vacuum tank filling method can be used for small pumping stations without bottom valves.
3. Before starting the stainless steel vacuum pump, fill the water tank with water to seal. After the start of the pump, the pump enters the water from the vacuum tank. As the water level of the tank drops, a certain vacuum will be formed in the tank. Under the action of atmospheric pressure, the water in the intake pool will enter the tank through the intake pipe, thus forming a water cycle, which will make the pump start to operate normally.
4. The most common usage is to install the manual pump on the suction hole of the stainless steel vacuum pump or on the intake pipeline near the pump for air pumping and water diversion, making it a tool for filling water when the stainless steel vacuum pump is turned on, thus saving the bottom valve of the intake pipeline of the pump, reducing energy consumption and improving the efficiency of the pump device. 。
5. Self-diverting water filling method for semi-submerged pumping station (that is, pumping station whose inlet pipe and pump top are all below the water level of the intake pool), water can be introduced into the pump by itself without manual irrigation and diversion. The advantages of this kind of pumping station are obvious, that is, it is easy to realize the automation of pumping station and has strong timeliness.
Filling the stainless steel vacuum pump is the work needed to maintain the equipment. Regular filling can prolong the service life of the equipment and improve the working efficiency of the machine. It is a two-in-one method.
