Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler pumps, in particular to a fire sprinkler pump. Background Art

[0002] Fire sprinkler pumps are key equipment in fire protection systems. They are used to provide sufficient water pressure and flow when a fire occurs to ensure that the sprinkler system can work effectively. They are usually composed of a pump body, impeller, bearings, seals and other components. The impeller is driven by an electric motor to rotate to generate centrifugal force, which sucks in water and pressurizes it to the fire sprinkler system. When the fire is large and the water supply in the fire truck is insufficient, water needs to be drawn from the nearest river. Therefore, the pump body needs to be placed in the river to pump water to extinguish the fire.

[0003] For example, a sprinkler pump for a fire engineering sprinkler pipe is provided in the Chinese patent application with application number 202220066758.5, including a mounting plate, a mounting groove is provided at the center position of the top plate of the mounting plate, a sprinkler pump body is provided in the mounting groove, the top surface of the mounting plate is provided with a limiting mechanism with a fixing bolt, and the bottom plate of the mounting plate is provided with an auxiliary mechanism with a support block. This technical solution is achieved by setting a support block, a rotating shaft, a support column, a limit block and a cone block. When the sprinkler pump body needs to be placed in a nearby river for pumping water, the support column can be removed from the cone block, and after the sprinkler pump body is installed, the sprinkler pump body can be placed in the river, so that there is a certain height difference between the sprinkler pump body and the bottom of the river, so that impurities such as silt at the bottom of the river are not easily blocked by the water inlet of the sprinkler pump body, thereby speeding up the pumping efficiency and extending the service life of the sprinkler pump body.

[0004] However, the following problems still exist in this technical solution: river water is extracted by a spray pump, but there is a lot of silt and impurities in the river water, and the device does not filter the silt and impurities in the river water.
