Fire pumps have become very familiar to us in recent years. On the one hand, it is due to the signal of the media and the propaganda of the governing bodies. On the other hand, due to the density of fires occurring more often. Bringing us to an urgent problem is to equip the fire protection system, equip the fire pump for our living and working environment.
How do we choose the pump to match the investment cost and operating range of the machine? This article will share with you a few ways to select a practical fire fighting system!
Fire protection pumps are mainly centrifugal pumps whose primary function is to pump water for fire fighting.
There are two types of fire pumps on the market today:
- The pump is compact, highly portable, and can be transported to many places for use. Example: Pumps mounted on fire trucks. Or portable fire pump,…
- And the other type of pump is often called a fixed pump station with very high pressure and flow. For example, Sprinkler system, fire sprinkler system, fire pump system for buildings, work,…
Currently, most fire protection water pumps use two types of gasoline or diesel engines for the backup pump. And run 3 phase electricity for the main pump.
How to choose a fire pumps?
For a pump specializing in pumping water for fire fighting, the specifications on flow and pressure are the two most important factors for users to refer to before buying a pump.
- Pressure refers to the pressure of the water flowing out of the pump and nozzle. It means that the higher the pressure, the more force there is to push the water out of the pump.
- Flow is related to the amount of water coming out from the pump; the more significant the flow, the more flow.
⇒ These are both essential factors in determining precisely a suitable fire water pump according to the needs.
- Pressure is significant for fire pumps because users will need a lot of water pressure to extinguish the fire ultimately when fighting a fire. The higher the pressure, the greater the total head, which will increase the distance the water can spray to extinguish the fire.
- Flow to determine how much water moved in a given period. In the event of a fire, the user will need a high-flow pump to transport as much water as possible to the location of the fire quickly to extinguish the fire immediately.
→ Both the flow and the pressure of the fire pump have an interaction with each other. And this may affect the user’s general fire resistance. As the pump flow increases, the pressure decreases, and vice versa. When the pressure increases, the pump flow decreases.
In addition to the two factors above that significantly affect how we choose our fire protection pump, you also need to pay attention to issues such as:
The size of the pump the user chooses depends on the application, terrain and pumping environment. If the pump’s location needs to be has a slope, height, for example, pumping a fire protection system for a high-rise building, the user should invest in a pump with large size or a pump capable of pumping out a large amount of water.
If the user does not know what size pump to choose, please contact a specialist or supplier for detailed advice because pumps for fire protection systems require incredibly high efficiency and always ready in any situation. Because once an incident occurs, if the pump is not qualified, does not meet the work in an emergency, there will be a lot of damage to property or even human life.
Choose pump nozzle size
An essential thing besides pump size is the pump nozzle size that users should not ignore. The hose size for the commonly used fire pump is 1.5 hose. This is the hose size many municipal fire departments use (although hose sizes up to 2 and even 2.5 can also be used). And is the best hose size for fire fighting and fighting.
Therefore, before choosing to buy a hose, users should make sure the hose size is suitable for their pump application and make sure the hose is ideal for the pump’s discharge port for connection.
Fire protection system
The most common fire fighting systems today are usually sprinkler systems. The sprinkler system consists of several sprinklers connected through a piping system.
Once a high temperature is detected, the system automatically activates the sprinklers at specified intervals to protect the location where the sprinklers installed. Therefore the sprinkler system is an automatic fire extinguishing system.
Wet piping systems regularly filled with pressurized water both above and below the damp pipe alarm valve. When there is a problem, the water will discharge immediately when the pump nozzle is activated.
Piping systems usually installed in locations where there is no risk of freezing water in the pipeline.
