Water injection device for main and auxiliary engines of ships

Abstract

The invention provides a water feeding device for main and auxiliary engines of a ship. The water feeding device comprises a water storage tank, a water pump, a water inlet pipe, a water outlet pipe and a water filtering pipe, wherein an injection hole is formed in the upper part of the water storage tank; knife gate covers are arranged at two sides of the water storage tank; the water storage tank is provided with an electric control cabinet and a plurality of electric heaters and is connected with a temperature controller; the water pump is fixed on an outer wall of the water storage tank and a water inlet of the water pump is connected with one end of the water inlet pipe; the water inlet pipe is provided with a water guide hole and the other end of the water inlet pipe is provided with a suction check valve and stretches into the water storage tank; a water outlet of the water pump is connected with one end of the water outlet pipe; the water outlet pipe is sequentially provided with a pressure releasing pipe, a first pressure gauge and a vacuum pressure gauge in sequence; the pressure releasing pipe is provided with a stop valve; one end of the water filtering pipe is communicated with the water storage tank. According to the water feeding device for the main and auxiliary engines of the ship, provided by the invention, a waste oil feeding device is modified and requirements of a water feeding process can be met; the effects of lowering the cost and increasing the effect are realized.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding and relates to the water throwing operation of the main and auxiliary engines of the ship, in particular to a water throwing device for the main and auxiliary engines of the ship. Background technique [0002] In the process of ship construction, some ship types are not designed with main and auxiliary fresh water (standby) pumps, so they cannot be directly put into water. Due to the small space on site and the difficulty of installing numerous water injection auxiliary equipment, in order to meet the water injection process requirements, it is necessary to set up corresponding devices and tooling for infield water injection operations. Therefore, we conducted research on the market, but did not find any water injection device specially designed for water injection operations; and the oil injection device is designed for oil characteristics, so it is difficult to meet the water injection requ...
