In raising this question, let us first understand what the fire protection electrical control device is, the fire protection electrical control device is used for the fire pump start, automatic control and inspection, with control, accept the signal, check the operating status, issue an alarm and other functions.

Control cabinet suitable for the main role of control and inspection, a variety of small communities, villas and other fire fighting water supply systems, industrial or civil buildings, libraries, oil loading and unloading terminals, logistics parks, hospitals, schools, Shi type square and other public facilities of various fire hydrants, sprinkler fire main pump, fire booster stabilized water supply equipment and other fire fighting water supply systems.

What are the main components of a fire pump?
The main components of a fire pump are the impeller, the pump casing and the shaft sealing device.

Fire pump is a more important piece of equipment on the fire fighting system, of course, the correct installation and use of the method is the premise of the normal operation of the fire pump, the following with you, the fire pump of these precautions.

Fire pump is an important equipment in the fire fighting system, whether the normal operation of the fire pump is vital, a little problem with the fire pump can not be ignored, and not the purchase of the fire pump everything is fine, we also need to understand the fire pump, found simple problems can understand and deal with, so as to more effectively ensure the safety of the use of the fire pump.

Fire pumps in the process of use, there may be a variety of problems, the following zjbetter of the editorial with you to analyze, the causes of leakage in the fire pump and how to repair. In order to facilitate the use of fire pumps in the process, if you encounter the problem of leakage to be able to eliminate the problem and repair themselves. The following is the fire pump leakage of several causes and solutions, for reference only:

Fire pumps are extremely susceptible to freezing and cracking in the cold and will not work properly when damaged, endangering people's fire safety.

We all know that the density of water is usually 1 g/cm3, the density of ice is usually 0.9 g/cm3, when the water into ice, the volume will certainly become larger, resulting in pump shell expansion crack. Therefore, if water is still present in the pump body under low temperature conditions, the pump body is extremely prone to swelling and cracking. In order for the pump to be used effectively even in winter, we need to provide some protection for the fire pump against freezing and cracking in winter.

Flow rate and head is an important parameter of fire pumps, in the process of use, found that the flow rate or head is not enough how to do? For example, if a fire breaks out in a high-rise area, the water flow will not reach the scene if the head is not enough, and the fire will not be extinguished in time; when the fire is bigger, the smaller flow cannot extinguish the fire, which also delays the best time to put out the fire.
