| Technical innovation of motor-driven fire pump
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.
