Description
Technical Field
The utility model relates to a water conservancy desilting dredging technical field especially relates to a novel desilting dredge diesel engine cooling device.
Background
The yellow river is a typical wide and shallow swimming river course, the water is less, the sand is more, and the river channel silts seriously. The dredging dredger is important equipment for ensuring normal use of a water intake and a grit chamber, and the diesel engine is a power heart of the dredging dredger. The cooling system of the diesel engine is formed by cooling the heated parts of the diesel engine in order to ensure the normal operation of the diesel engine, which inevitably generates heat during the operation of the diesel engine. Currently, there are two main cooling methods for marine diesel engines: open cooling and closed cooling.
The open cooling means that a seawater pump directly pumps rivers or seawater into a machine body for circular cooling and then discharges the seawater out of the board. Closed cooling is to install a cooler (generally a plate-type or shell-and-tube cooler) on the ship, and to use clean fresh water to cool the body and heated components. Fresh water in the cooler enters the machine body to circulate and then returns to the cooler to form closed circulation. However, if the cooler is too large, it will occupy a large space of the ship, and if it is too small, the water temperature will rise after long-time operation, and after reaching a certain temperature, the diesel engine will not work normally. In order to achieve cooling with a smaller cooler, the cooler needs to be cooled with rivers or sea water. The seawater pump is used for pumping the outboard water, and the outboard water is discharged out of the outboard after cooling the cooler. This approach is also known as central cooling.
Because the yellow river water is less and has more sand, the river water enters the engine body to cause the damage of the diesel engine, and when the yellow river water enters the ship to cool the cooler, the river sand is deposited to block the cooler. Therefore, neither of these cooling methods is applicable in a yellow river dredging vessel.
How to solve the problem of cooling a diesel engine of a yellow river dredging ship and ensure the normal operation of the ship is the problem which needs to be solved urgently at present.
SUMMERY OF THE UTILITY MODEL
