How to fill water in vacuum pump of water supply ring

Generally, we will have a full understanding of the water ring vacuum pump before using it, so we understand the importance of filling water to the equipment, and the water filling operation is an important part of the pump operation management. Only when the water pump and the water inlet pipe are filled with water before starting the equipment can they work normally. If the equipment does not discharge water after starting, it is generally caused by the air in the pump is not discharged completely and the water is not filled. This also reminds us that there are abnormalities, so we need to check them carefully. So, how to fill the equipment with water?

1. Manual water filling method for small pump station with inlet pipe diameter less than 300 mm, a bottom valve is usually set at the inlet of the inlet pipe, and manual water filling method is generally adopted, that is, water is filled from the special water filling and exhaust hole on the upper part of the pump shell by the water filling funnel (or an inverted ordinary bottle with the bottom removed).

2. For small pump station without bottom valve, vacuum water tank filling method can be used.

3. Before starting the water ring vacuum pump, fill the water tank with water for sealing. After the water pump is started, the water enters from the vacuum tank. As the water level of the water tank drops, a certain vacuum will be formed in the water tank. The water in the water inlet tank will enter the water tank through the water inlet pipe under the action of atmospheric pressure, so as to form the water circulation and make the water pump start to operate normally.

4. Common usage: install the manual pump on the suction hole of the water ring vacuum pump or on the water inlet pipe close to the pump, conduct the suction and water diversion, make it a tool for filling water when the vacuum pump starts, thus eliminating the bottom valve on the water inlet pipe of the pump, reducing the energy loss, and improving the efficiency of the pump device.

5. For the pump house with semi submerged type (i.e. the elevation of the water inlet pipe and the top of the pump is below the water surface of the water inlet pool), the water can be introduced into the pump by itself without manual water filling. The advantages of this kind of pump station are obvious, that is, it is easy to realize the automation of the pump station and has strong timeliness.

Therefore, before starting the water ring vacuum pump for work, we must do the relevant preparations well, and the operators must master the safe and correct working methods skillfully, so as to ensure the normal operation of the equipment, reduce the number of problems in the operation process, greatly reduce the occurrence of accidents, so as to ensure that the safety of the operators themselves is not threatened.
