Fresh water cooling and dosing system

Abstract

The invention discloses a fresh water cooling and dosing system. The fresh water cooling and dosing system comprises a cylinder jacket water expansion water tank system, a cylinder jacket water circulating pump system, a main machine cylinder jacket system and a dosing device. A main body of the cylinder jacket water expansion water tank system is a second tank, and a main body of the dosing device is a first tank; the topmost portion of the first tank is lower than the bottommost portion of the second tank; a first branch is formed in a pipeline connected between an outlet of the cylinder jacket water circulating pump system and an inlet of the main machine cylinder jacket system; an inlet of the first tank is connected with the first branch; a second branch is formed in a pipeline connected between an inlet of the cylinder jacket water circulating pump system and a second outlet of the main machine cylinder jacket system; an outlet of the first tank is connected with the second branch. The fresh water cooling and dosing system has the advantages that the bottommost portion of the second tank of the cylinder jacket water expansion water tank system is higher than the topmost portion of the first tank of the dosing device; when liquid in the two tanks has hydrostatic pressure, a water pump in the fresh water cooling system circulates derusting liquid in a forced way, and the derusting liquid is fully mixed with fresh water quickly, so that the derusting time is shortened, and the derusting effect is improved.

Description

technical field [0001] The invention relates to the technical field of fresh water cooling of mechanical equipment, in particular to a fresh water cooling and dosing system. Background technique [0002] At present, in ships powered by internal combustion engines, there are many mechanical equipment that emit a large amount of heat during normal operation, so as to ensure that the working temperature of the heated parts will not rise sharply and cause overheating to destroy the work of the mechanical equipment. The mechanical equipment is supplied with enough fresh water for cooling to ensure the reliable operation of the mechanical equipment. [0003] Most of the pipes of the fresh water cooling system are made of seamless steel pipes, and the surface of the pipes is phosphated after production. It generally takes 8 to 10 months from the beginning of the production of the pipeline to the start of adding water to the system. During this period, the seamless steel pipe is ba...

Problems solved by technology

[0005] In the common jacket water cooling system, the agent is added through the dosing port on the jacket water expansion tank, but since the water in the expansion tank is not forced to circulate, it only replenishes the fresh water in the circulation, and the dispersion speed of the agent is very slow, which lengthens the The time of rust removal, and the uneven spread affects the effect of rust removal
