Motor driven fire pump is a
kind of fire pump which is directly connected with light engine and water pump
and can be moved or fixed by manpower to put out general material fire and small
oil fire. Due to the advantages of portability, flexibility and freedom from
traffic, power and regional barriers, the motor driven pump has been widely used
to put out the initial fire in places with poor road access conditions, such as
industrial and mining enterprises, warehouses, ports, docks and rural areas,
where it is difficult for fire engines to pass or reach in time.
Motor driven
fire pump is mainly composed of engine, water supply system and fixed support.
At present, the water inlet of the fire pump used at home and abroad is hard
tubular (determined by the operating principle of the equipment), and the screw
thread rotary sleeve method is generally used between the water inlet of the
pump body and the water intake pipe. The main problems of this method are as
follows: the user must insert the threaded joint of the water intake pipe into
the threaded pipe orifice at the other end of the water pump inlet in a parallel
rotation way, which is hard and time-consuming; In addition, when the water
inlet pipe is aging and hard, especially in winter, it is difficult to quickly
install the water inlet pipe. In case of fire, it will bring great trouble to
users. In case of fire alarm, fire fighting is against time, so the application
of this technology greatly reduces the difficulty of operation and improves the
actual application performance of the product.
Zhejiang Yu'an improved the
original product. After the improvement, the products were compared. The
specific parameters (of the same group of operators) are as follows: the water
filling time of the fire pump before the improvement is 110 seconds; The water
filling time of the improved fire pump is 40 seconds.
So where is 70 seconds
saved? 1. When the motor-driven fire pump is under vacuum, Yu'an adopts the
one-way valve technology, which eliminates the need to manually close the
connection switch for 6 seconds; 2. After Yu'an improved the connection between
the water inlet and the water diversion pipe of the fire pump, the time required
for the quick coupling connection method is 1 second; It took 65-95 seconds for
the original thread mode; How long does it take for a fire to burn violently
from the initial stage? Class A fire generally lasts about 5 minutes; Class BC
fire generally lasts about 2 minutes; It can be seen that the application of
this technology will greatly improve the fire extinguishing efficiency,
effectively control the further upgrading of fire, and greatly improve the
excellent performance of this product.
