Boat-oriented emergency fire pump unit with power pump for priming water

Abstract

The invention discloses a boat-oriented emergency fire pump unit with a power pump for priming water. The boat-oriented emergency fire pump unit comprises an internal combustion engine, a fire control self-priming pump, an inner combustion engine free end power output wheel, a priming pump power input wheel, a transmission flexible shaft, a priming pump, a tee joint and a main pipeline. The emergency fire pump unit is installed on a ship deck. The inner combustion engine free end power output wheel is connected with a front shaft of the free end of the internal combustion engine. The inner combustion engine free end power output wheel drives the priming pump power input wheel which is connected with the underwater priming pump through the transmission flexible shaft. A water outlet pipe and a water inlet flexible pipe are arranged on the fire control self-priming pump. The water inlet flexible pipe, the main pipeline and a water outlet of the priming pump are communicated through the tee joint. The boat-oriented emergency fire pump unit with the power pump for priming water has the advantages that the priming pump which is possessed by a boat-oriented fire pump and carries out transmission through mechanical power is used for normally booting a boat-oriented emergency fire pump to carry out emergency fire control work. The boat-oriented emergency fire pump unit is not affected by a priming range and free of manual water priming, and has the advantages of being simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a marine emergency fire pump set with its own power pump for water diversion, and belongs to the technical field of marine emergency fire pumps. [0002] Background technique [0003] In order to ensure fire safety, in accordance with the ship classification and construction regulations, the ship must be equipped with an emergency fire pump outside the main engine room to play a role in fire fighting and extinguishing in the event of failure of the main fire pump in the engine room. Usually the emergency fire pump has electric pump set and internal combustion engine emergency fire pump set. Generally, the electric emergency fire pump set is installed in the cabin under the main deck, while the emergency fire pump set driven by internal combustion engine (diesel engine or gasoline engine) is installed in the main deck. deck surface. [0004] Since the internal combustion engine emergency fire pump set is installed on the deck ...

AI Technical Summary

Problems solved by technology

[0005] Since artificial irrigation needs to have water sources and time, and because the ship is on the sea surface and the suction height changes due to wind and waves, the technical conditions of the original emergency fire pump are difficult to meet the urgent water supply requirements for emergency fire protection.
