Fire pump is a relatively professional fire fighting tool, which plays a vital role in our lives and is related to the life safety of many people. They can be seen in almost every corner of office or community in the city. Many people think that firefighting tools should be professionals, but in fact, in many emergency situations, we may use them ourselves.
Let’s take a look, what should be paid attention to before starting:
1. Check the status of the process valve switch. Sometimes, due to long-term use or failure, the valve switch will not open when needed, which poses a big safety hazard. It is very important to check the switch status of the corresponding return valve and whether it can meet the requirements. In this process, we need to understand that the return valve should be fully open, while the valve group valve is in a tightly closed state. In addition, professional knowledge also includes that when trying out the foam outlet, you need to close several foam tank valves at the inlet.
If you don’t understand, you can ask professionals to explain, or you can search and query on the Internet, and you will gradually understand them. In addition, it should be noted that opening one of the return valves can start the pump. And after all of these are completed, remember to restore all valves to their original state. Once a real emergency situation arises or a fire pump is needed for an exercise, the corresponding demand valve in the valve block should be opened and the return valve should be in a tightly closed state.
2. The handle state of the clutch should be in the “closed” position for removal of silt. We must pay attention to these small details.
3. Turn on the bleed switch and close the valve after resetting the float. Before the fire pump is started, it is mainly to check some small aspects.
