Abstract
The utility model discloses a diesel engine pressurizing gas cooling device, which comprises an intercooler (1). The cooling device is characterized in that an electric-controlled temperature regulating valve (2) is arranged in a cooling device of the intercooler (1). When in work, the electric-controlled temperature regulating valve can regulate coolant entering the intercooler according to actual temperature to guarantee no rapid cooling of cooled high-temperature gas and no generation of a large amount of accumulated water, and avoids the hidden hazard of a diesel engine due to accumulated water of a gas inlet pressure stabilizing case.
Description
Technical field
The utility model relates to a kind of cooling unit, particularly a kind of diesel engine supercharging gas quench system.
Background technique
Need infeed pressurization gas during marine diesel engine work, because gas can produce high temperature after the pressurized machine supercharging, therefore utilize cooling system that pressurization gas is cooled off, cooled pressurization gas enters in the air inlet pressure stabilizing chamber, and then infeeds in the firing chamber of diesel engine.Because marine diesel engine all utilizes the water in waters, place to cool off; relative temperature is lower; can make that the higher gas of temperature turns cold rapidly after the pressurized machine supercharging; if gas humidity is bigger; in the process of being cooled off rapidly, just have a large amount of water recovery Cheng Shui, enter air inlet pressure stabilizing chamber, cause the pressure stabilizer drain pipe often to have a large amount of water and discharge; explanation in the pressure stabilizer inner accumulated a lot of water, this has caused very serious hidden danger for safe operation of diesel engine.
Need infeed pressurization gas during stationary diesel engine work, because gas can produce high temperature after the pressurized machine supercharging, therefore utilize cooling system that pressurization gas is cooled off, cooled pressurization gas enters in the air inlet pressure stabilizing chamber, and then infeeds in the firing chamber of diesel engine.Because stationary diesel engine all utilizes cooling tower to cool off; relative temperature is lower; can make that the higher gas of temperature turns cold rapidly after the pressurized machine supercharging; if gas humidity is bigger; in the process of being cooled off rapidly, have a large amount of water recovery Cheng Shui, enter air inlet pressure stabilizing chamber, cause the pressure stabilizer drain pipe often to have a large amount of water and discharge; explanation in the pressure stabilizer inner accumulated a lot of water, this has caused very serious hidden danger for safe operation of diesel engine.
Summary of the invention
