Abstract

The invention relates to a portable fire pump comprising a petrol engine (1) and a pump body (2), wherein the pump body (2) comprises a sealing base (4), a pump shell (3), a main shaft (5), three-level centrifugal impellers and two-level guide blades, wherein the sealing base (4) is connected with the petrol engine (1); the pump shell (3) is fixedly connected with the sealing base (4); the main shaft (5) is arranged in the center of the pump shell (3); the three-level centrifugal impellers are sequentially fixed with the main shaft (5); the two-level guide blades are sequentially fixed in thepump shell (3); the main shaft (5) is coaxially connected with an output shaft of the petrol engine (1); and the sealing base (4) is internally provided with a sealing device (6). The invention solves the technical problems of large size, heavy weight, high energy consumption and easy damage of the traditional fire pump, has the advantages of small size, light weight, portability, low energy consumption and technical effect of the portable fire pump which can automatically close the petrol engine (1) under the condition of an insufficient water source.

Description

technical field [0001] The invention relates to a fire pump, in particular to a portable fire pump. Background technique [0002] The fire pumps used for fire protection and domestic water supply in narrow streets in cities and towns, small rural roads, steep slopes in mountainous forests, etc., are large in size, heavy in weight, high in energy consumption, and are easy to damage the fire pump and gasoline engine when the water source is insufficient. Existing fire pumps use 1-stage arc blades or 3-stage arc blades, which are relatively large in size, heavy in weight, high in energy consumption and easily damaged. Contents of the invention [0003] The object of the present invention is to provide a portable fire pump with small volume, light weight, easy to carry, low energy consumption, and can automatically shut down the gasoline engine when the water source is insufficient, which solves the problem of large volume, heavy weight, and energy consumption of existing fire...
