Answer: First of all, we must understand the relationship between pressure and lift: pressure = liquid density * g * lift (g = 0.981). In fact, the fire water pump can not only transport water, as long as the physical and chemical characteristics and water liquid are fine, but most of them transport water in daily life. The density of water is 1 ton per cubic meter. It can be obtained from the above formula : Pressure=1000*0.981*lift, pressure=0.981*lift, at this time the pressure and lift are almost the same, so whether we refer to lift or pressure, it can basically be regarded as a parameter.

Fire pumps can be powered by various sources, including electricity, diesel engines, and, in some cases, natural gas. The selection of a power source depends on factors such as reliability, availability, and the specific requirements of the facility.

Electric fire pumps are commonly used in urban areas with a stable power supply. They are efficient and can start automatically in response to a fire alarm signal. In contrast, diesel-powered fire pumps are reliable in areas with inconsistent power availability, as they can function independently. The choice of power source should align with the facility’s operational conditions and the need for uninterrupted fire protection.

1. The fire pump packing seal should be able to form a reliable seal without leaking, and it should have good wear resistance.
