Water pump for ship exhaust gas washing water pipeline

Abstract

The invention discloses a water pump for a ship exhaust gas washing water pipeline, and relates to the technical field of water pumps. The water pump for the ship exhaust gas washing water pipeline includes a shell, the top of the shell is provided with an outer frame, the top of the shell is provided with a corrugated pipe in a penetrated manner, a movable plate is arranged at the top end of thecorrugated pipe in a sealed manner, and an electric brush is arranged on the left side of the movable plate. According to the water pump for the ship exhaust gas washing water pipeline, an output pipe, an input pipe and a leakage preventing pipe are improved, the corrugated pipe, a driving mechanism, a curved rod, a movable ring and other components are used in cooperation, and the air pressure ofan inner cavity of the shell is changed; the manner that the output pipe, the input pipe and the leakage preventing pipe restrict flow of liquid is adopted to provide hydraulic pressure, and rotationblockage caused by the fact that an impeller or a gear is affected by impurities in liquid is avoided; and meanwhile, the number of turning points is reduced, and liquid channel effective cross-sectional area reduction caused by accumulation of the impurities in the liquid at the turning points is avoided.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a water pump used for a ship exhaust gas washing water pipeline. Background technique [0002] A water pump is a device used to provide hydraulic pressure for liquid flow. In the use of ship exhaust gas washing water pipelines, water pumps are generally used to provide hydraulic pressure for liquid flow. [0003] The traditional water pump provides hydraulic pressure through the rotation of the impeller or gear, and there are many turning points in the route of the liquid flowing in the pump. When it is applied to the ship exhaust gas washing water pipeline, it is easy for the impeller or gear to be affected by impurities in the liquid and the rotation is blocked. At the same time It is easy to cause the effective cross-sectional area of ​​the liquid channel to shrink due to the accumulation of impurities in the liquid at the turning point, which reduces the working efficienc...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a water pump used in the pipeline of ship exhaust gas washing, which solves the problem that the water pump provides hydraulic pressure through the rotation of the impeller or the gear and there are many turning points in the route of the liquid flowing in the water pump. When used in ship exhaust gas washing water pipelines, impellers or gears are likely to be blocked by impurities in the liquid, and at the same time, the effective cross-sectional area of ​​the liquid channel is reduced due to the accumulation of impurities in the liquid at the turning point.
