Description

Technical Field

[0001] This utility model relates to the field of fire water supply equipment technology, specifically an integrated vortex preventer for fire pumps. Background Technology

[0002] In fire-fighting water supply systems, water pumps are core power components, and their operational reliability directly affects the effectiveness of fire emergency response. When no suction well is installed at the suction inlet, a vortex preventer must be installed according to relevant technical specifications to prevent the water flow from creating vortices that draw in air. If the vortex phenomenon is not effectively controlled, it may lead to cavitation problems inside the water pump, manifesting as noise and vibration during operation. Over time, it can also cause corrosion and damage to the flow-through components, and in severe cases, it will lead to a decrease in the pump's flow rate, head, and other performance parameters, affecting the stability of the water supply.

[0003] Most existing vortex preventers adopt a multi-component assembly structure, such as Figure 1 As shown, the vortex preventer cover 1 needs to be fixed to the suction pipe 5 using connectors such as flanges 4. However, to facilitate the installation of fastening bolts 3, the flanges 4 on the vortex preventer cover 1 are connected to it via a vertical pipe 2, which limits the height of the minimum fire water level 6 and makes the installation process relatively cumbersome. Therefore, an integrated vortex preventer for fire pumps is proposed. Utility Model Content

[0004] The present invention aims to solve the above-mentioned problems, thereby providing an integrated vortex preventer for fire pumps that can effectively solve the problems of limited installation of existing vortex preventers and the need to increase the size of the water tank.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is: An integrated vortex preventer for fire pumps includes a vortex preventer housing and a suction pipe. The vortex preventer housing and the suction pipe are integrally formed, and the connection end between the suction pipe and the vortex preventer housing is bent at 90°. Multiple water inlet holes are provided on the circumferential sidewall of the vortex preventer housing. One end of the suction pipe is connected to the interior of the vortex preventer housing, and the other end is used to connect to the suction port of the fire pump.

[0006] Furthermore, the water inlet holes are evenly distributed on the circumferential sidewalls of the vortex preventer cover, and the total flow area of ​​all water inlet holes is greater than 1.2 times the flow area of ​​the water suction pipe; this allows water to enter the cover from different directions in a balanced manner, reducing the turbulence caused by water flow impact. Combined with a reasonable flow area setting, this ensures water intake efficiency and avoids the formation of vortices due to excessively fast local water flow.

[0007] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: This utility model adopts an integrated design of the vortex preventer cover and the water intake pipe, which avoids the use of flanges and other connecting parts and additional connecting pipes in traditional multi-part assembly structures, simplifying the installation process. At the same time, the 90° arc transition design at the connection point reduces the restriction on the minimum fire water level, allowing more fire water to be fully utilized. It solves the water level restriction problem and cumbersome installation problem caused by flanges and connecting pipes in traditional assembly structures, ensuring that the fire pump reduces the generation of vortices when drawing water, reduces the risk of cavitation, and improves operational reliability.
