Motor fire pump is a light engine and pump directly connected to the human movement or fixed by the use of fire pumps used to fight the general material fire and small oil fires. Due to its advantages of light weight and flexibility, it is not restricted by traffic, power and regional barriers, it has been widely used in the fight against the poor traffic conditions such as industrial and mining enterprises, warehouses, ports, wharves and rural areas, the inaccessible or inaccessible fire engines The beginning of the place of fire. Motor fire pump mainly by the engine, water supply system and fixed bracket and other components. Currently used fire pump inlet at home and abroad for the rigid tube (which is due to the use of equipment, the principle of decision), the pump inlet and the diversion tube screw thread commonly used between methods. The main problems of this method are as follows: the user must put the lead screw thread connector in a parallel rotation way into the other end of the screw thread nozzle of the water inlet of the water pump, which is hard and time-consuming. In addition, when the inlet pipe is aged and hardened Especially in the winter it is difficult to quickly install the inlet pipe, in case of fire will bring great trouble for the user. In case of fire, fire fighting is a matter of seconds, so the application of the technology greatly reduces the difficulty of operation to enhance the practical application of the product performance. Zhejiang Yuan to improve the original product, improved, the product is compared, (the same group of operators) specific parameters are as follows: unmodified fire pump water time: 110 seconds; improved fire pump water time: 40 seconds. So where the middle of saving 70 seconds is generated? 1, the vacuum pump Yu Yu is the use of one-way valve technology, eliminating the manual switch connected to the time is 6 seconds; 2, between the fire pump inlet and diversion pipe Yu improved after the use of quick connector The time required for the connection method is 1 second; the original thread time is between 65-95 seconds; what is the time required for the fire from the early stages of combustion to the intense combustion? Class A fire is generally about 5 minutes; BC class fire is generally about 2 minutes; This shows that the application of the technology will greatly enhance the efficiency of fire extinguishing and further control the fire to further upgrade, greatly improving the excellent performance of the product.
Globe Valve
