No need for an underground fire pump room – self-priming installation scheme for synchronous discharge and suction fire pumps

Thread Content

Synchronous suction-discharge fire pump – a self-priming fire pump installed directly above the water tank. The synchronous suction-discharge fire pump is a self-priming water pumping fire pump that is installed above the liquid level; since the plane of its pump shaft remains below the surface of the self-priming device, water flows naturally into the pump under the effect of gravity when the pump is started, allowing water to be delivered in just zero seconds. Furthermore, this pump not only meets the requirements for self-priming but also has a self-priming function; its self-priming height can reach 8.5 meters, and the horizontal distance of the inlet pipeline can be up to one kilometer. At the same time, since this pump does not require the construction of an underground pump room, it reduces civil engineering costs, shortens the construction period, and prevents accidents caused by flooding of the pump room, which has earned it high praise in the market. (Synchronous intake and discharge fire pumps are available in three types: XBD/TXD type synchronous intake and discharge fire pumps (motor-driven), XBC/TXC type synchronous intake and discharge fire pumps (diesel engine-driven), and TXB type synchronous intake and discharge variable-frequency fire (domestic) water supply equipment). All of these three types have passed the mandatory testing and 3C certification conducted by the Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Fire-Resistant Components (i.e., Tianxiao Suo); therefore, they are required to be approved everywhere in the country.) The above three types of inspection reports as well as 3C certification can be searched for by visiting the China Fire Protection Products Information Network and entering our company name. 2 In the \"Code for Design of Building Water Supply and Drainage GB50015-2009\" (2.1.32), the term for self-priming refers to the method in which water enters the pump body under the force of gravity when the pump starts. Although the synchronous exhaust fire pump is installed above the water tank, the plane of its pump shaft is below the liquid level of the front-mounted self-priming device. When the pump is started, water flows naturally into the pump due to gravity, and it is then sent into the pipeline system as the impeller rotates, allowing water to be discharged immediately upon startup. It fully meets the requirement in the \"Technical Code for Fire Water Supply and Fire Hydrant Systems GB 50974-2014\" that fire pumps should have a self-priming suction function. 3 The current codes, such as the \"Code for Fire Protection Design of Petrochemical Enterprises\", the \"Code for Design of Oil Depots\", and the \"Code for Fire Protection Design of Thermal Power Plants and Substations\", all specify that our synchronous discharge-type fire pumps can be used for fire protection water supply. 4 Since the company was established in 2007, many projects across various provinces, cities, and industries across the country have adopted our synchronous intake and discharge type water pumps for fire protection purposes. Moreover, in cities in China with the strictest fire safety regulations such as Beijing, Shanghai, Tianjin, and Guangzhou, there is a continuous stream of fire protection projects. Installation method of synchronous discharge pumps. In addition, our synchronous discharge fire pumps can make full use of existing natural water sources, rainwater, reclaimed water, landscape water, etc., around them as fire-fighting water; the fire pumps can be installed within a radius of up to a thousand meters from these water sources, meaning that the horizontal distance between the pumps and the water sources can reach one kilometer. There is no need to rebuild the fire water tank and pump room, which saves investment while making full use of the existing operating conditions. For example, Shanghai Zhongran Shipbuilding Co., Ltd. uses water from the Huangpu River for fire fighting (with the horizontal distance between each inlet pipe being over 70 meters), while Jiangsu Lianyungang Shenzhou New Energy Co., Ltd. uses landscape water for fire fighting (with the horizontal distance between each inlet pipe being around 300 meters). For this reason, in recent years, our synchronous suction fire pumps have achieved highly convincing results across various provinces and cities throughout the country, as well as in different industries. In the future, fire departments will no longer need to build underground pump rooms; fully above-ground synchronous suction and discharge fire pumps can easily provide fire fighting water.

If you are interested in information regarding the working principle, product samples, selection guides, and other related materials, you can add me as a friend, and I will send you a detailed set of sample materials. For some extreme operating conditions, technical experts can also be arranged to provide you with solutions! I hope to have the opportunity to work with all of you friends.
