In small and medium-sized towns, industrial and mining docks, rural areas and other areas, due to traffic restrictions, it is difficult for fire trucks to reach, or to arrive in time, motor fire pump with hose, water gun, suitable for fighting general material fire, and not subject to traffic, power, regional restrictions. At present, the main commonly used hand lift mobile fire pump and float fire pump two kinds. Portable Fire Pump manufacturer generally consists of gasoline engine, single stage centrifugal fire pump, water diversion device, hand lift frame and other accessories.
According to the different working cycle of gasoline engine, the manual fire pump is divided into four stroke and two stroke two hand lift electric fire pump. A four-stroke gasoline engine rotates twice to complete one cycle, while a two-stroke gasoline engine completes one cycle for every revolution. Four-stroke gasoline engine has a better distribution mechanism, which ensures that the engine has a higher cylinder charging coefficient, better combustion process and better economic performance. The four-stroke gasoline engine is equipped with special lubrication mechanism, the lubrication condition of parts is good, and the service life is long. At the same time, the use of four-stroke gasoline engine does not burn mixed oil, easy to use. At present, the four-stroke gasoline engine has been widely used in hand lift motor pump, such as BJ L5, BJ l0A and so on.
Portable Fire Pump applications and current status
The two-stroke gasoline engine has no distribution mechanism and special lubrication mechanism, but it is simple in structure, small in size, large in power and light in weight. These advantages for hand pump, hand pump machine volume portable fire pump, light weight, good mobility, is also widely used. However, the cylinder inflation coefficient of two-stroke gasoline engine is low, and some unburned fresh mixture is discharged in the intake process, so the economy is poor, and the two-stroke gasoline engine needs to burn the mixture of gasoline and lubricating oil, such as BJ25D, BJ22 and other high-power hand pumps use two-stroke gasoline engine.
Handlift mobile fire pump can also be divided into two kinds of single cylinder and double cylinder according to the number of engine cylinders, such as BJ7, BJ331, BJl0A are single cylinder engine, BJ20, BJ22, BJ25 are double cylinder engine.
There are seven, nine, 11, 15, 20, 22, and 25 horsepower engines. At present, the 46 horsepower high power fire pump developed by our company makes up for domestic gaps and is the best substitute equipment for imported products.
