Problems solved by technology

In this traditional working process, the water pipe connected to the fire pump only plays the role of pipeline transportation without any other function. As we all know, the vacuum pump is a very precise and expensive equipment, and its failure rate is also very high, which directly affects the fire protection. pump performance

Abstract

The invention discloses a self-sucking water pipe used for a fire-fighting water pump. A self-sucking device with a built-in submersible pump is connected to the other end of the self-sucking water pipe; the self-sucking device comprises a shell body, and the vertical submersible pump is mounted in the shell body; a water outlet of the submersible pump is connected with one end of a branch pipeline, and the other end of the branch pipeline is connected to a notch located in the side wall of the self-sucking water pipe; the notch penetrates through the side wall on one sides of the self-suckingwater pipe and a connector, and the branch pipeline is in threaded connection with the notch; and a controller is connected to the submersible pump through a circuit, and the controller is connectedwith a flow sensor located in the self-sucking water pipe through a circuit. According to the self-sucking water pipe used for the fire-fighting water pump, through the submersible pump structure, theself-sucking performance of the self-sucking water pipe is achieved by utilizing the technical performance of direct water pumping of the submersible pump, so that mounting a vacuum pump on the fire-fighting water pump is avoided, and the technical purpose of quick starting of the fire-fighting water pump is realized.

Description

technical field [0001] The invention relates to a pipe with a self-suction function, in particular to a self-suction pipe for a fire pump. Background technique [0002] In the technical field of fire-fighting pipelines and fire-fighting water pumps, before the fire-fighting water pump is started, a vacuum pump is generally required to evacuate the interior of the fire-fighting water pump to form a vacuum negative pressure to realize the high-pressure water outlet of the fire-fighting water pump. In this traditional working process, the water pipe connected to the fire pump only plays the role of pipeline transportation, and has no other function. As we all know, the vacuum pump is a very precise and expensive equipment, and its failure rate is also very high, which directly affects fire protection. pump performance. How to avoid using a vacuum pump by improving the technical structure of the water pipe, thereby reducing the manufacturing cost of the fire pump and improving ...
