Shandong Boshan Fire Pump Manufacturer

Description :

　　Most fire water sources provide firefighting water that requires pressurization by fire pumps to meet the requirements for water pressure and volume during firefighting. The malfunction of the water pump due to improper setting and maintenance will inevitably affect firefighting and rescue, causing unnecessary losses. Which brand of fire pump is good? What are the performance requirements for fire pumps? The performance requirements of NFPA20 for fire pumps in the United States are: the flow rate of the fire pump should be 150% of the design value, the head should not be less than 65% of the selected working point head, the head when the pump is turned off should not be greater than 140% of the selected working point head, the flow rate of the stabilizing pump should be 1-2L/S, and the head should be 1.1-1.2 times the head of the fire pump. At the same time, it is stipulated that a measuring flow meter should be installed on the outlet pipe of the fire pump, which should be able to test 175% of the selected flow rate of the water pump. A pressure gauge with a diameter greater than 89mm should be installed on the outlet pipe of the fire pump.

　　Regional distribution of fire pump manufacturers: Northeast region: mainly producing chemical pumps; North China region: mainly producing mud pumps; Southeast region: mainly producing civilian water pumps; Emerging enterprises, represented by Dalian Three Phase Machinery Equipment Development Co., Ltd., adhere to the pragmatic pursuit of innovation and perfection for small and medium-sized enterprises, and continuously develop and grow; Domestic pump R&D and processing enterprises, while constantly pursuing self-improvement, will inevitably go global with the deepening of technology research and development, becoming the world processing center of the pump industry. Enterprises can only invest a large amount of funds to purchase new pumps, while charging for a large number of components, resulting in a significant waste of funds. The design and manufacturing of domestic pumps basically follow the "metal" concept, which uses stainless steel and carbon steel materials as the main pump body materials. Faced with high corrosion and strong erosion environments, high nickel alloys are needed, and even excellent corrosion-resistant materials such as titanium, zirconium, tantalum, etc. are used. These rare metal materials are expensive and have large price fluctuations, and the high manufacturing cost and complex manufacturing process result in the high price of such pumps, which in turn leads to high procurement costs. With the development of international advanced pump body research and the application of new material pump bodies, domestic research institutions have drawn on the development ideas of pump body research in developed Western countries. A few domestic enterprises and institutions have begun to develop inorganic non-metallic materials such as ceramics, fiberglass, graphite and carbon products, as well as synthetic organic polymer materials such as plastics, glass fiber or carbon fiber reinforced engineering plastics. The development trend of these domestic pumps has catered to international trends and quickly achieved good results in domestic use.
