Compared with prior art, the utility model has the advantage of by installing automatic gas permeable devices additional at ME main engine jacket cooling water outlet, when being produced steam by the cooling fresh water vaporization of heating, when the air dissolved in fresh water overflows, steam and air pass to fresh water expansion water tank fast by gas permeable devices, and then steam is condensed liquefaction, air overflows from expansion water tank, decrease steam and the waiting time of air in cooling system of fresh water, cooling fresh water can supplement in time rapidly, reach the object improving cooling system fresh water cooled effect, by self running moved in circles, discharge the air in water-cooling tube and steam, serve permeation functions, efficiently solve ME EFI main frame because reducing operating mode to run in the cooling system of fresh water that causes in fresh water vaporization and fresh water air overflows the cooling system cooling effect reduction caused, a difficult problem for cylinder sleeve corrosion etc., and it is easy to operate simple and easy, later maintenance cost is relative moderate also.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
The automatic gas permeable devices of this ME EFI main frame cooling system of fresh water comprises main frame cooling system of fresh water, this overlaps automatic gas permeable devices and is usually installed on cabin Tween deck, in order to discharge air in main frame cooling system of fresh water in water-cooling tube and steam, and set up the automatic gas permeable devices that effectively can serve permeation functions.
As shown in Figure 1, automatic gas permeable devices comprises ventilation cabinet 1, warning chamber 2 and expansion water tank 3, the main engine jacket water out of main frame cooling system of fresh water connects ventilation cabinet 1 and warning chamber 2 successively by pipeline, wherein, warning chamber 2 exports and connects by pipeline the expansion water tank 3 being placed in main frame cooling system of fresh water peak.Particularly, the main engine jacket water out of main frame cooling system of fresh water is connected with the first import 11 of ventilation cabinet 1 by the first pipeline 6, first outlet 12 of ventilation cabinet 1 is connected with the import 21 in warning chamber 2, top, warning chamber 2 is provided with the ventilative pipeline 7 air of the water vapor produced in fresh water cooled process in main frame cooling system of fresh water and spilling being caused expansion water tank 3, this ventilative pipeline 7 is connected with the import 31 of expansion water tank 3, and current are returned main frame cooling system of fresh water by water pump by the first outlet (not indicating in figure) of expansion water tank 3.In addition, expansion water tank 3 is provided with a permeability cell (not indicating in figure) that air can be overflowed, and second of expansion water tank 3 the outlet (not indicating in figure) is connected with the second import 13 of ventilation cabinet 1 by water return pipeline 4, to be caused in ventilation cabinet 1 by the water of expansion water tank 3.And the cooling water in ventilation cabinet 1 still can flow back to main frame cooling system of fresh water through the second outlet 14 by return pipe 5.
In the present embodiment, in order to monitor the water level in ventilation cabinet 1, in warning chamber 2, be provided with liquid level sensor, and liquid level sensor 9 being the liquid level sensor 9 of floating-ball type, meanwhile, in expansion water tank 3, being provided with low liquid level sensor.In the floating-ball type liquid level sensor 9 in warning chamber 2 is because of chamber, is full of water and lifts and do not report to the police, playing the effect of secondary monitoring expansion water tank 3 liquid level, and cooperatively play the effect of double insurance with the low liquid level sensor of expansion water tank 3.
The specific works principle of this automatic gas permeable devices work is: when ME main frame operates for a long time at the load of 40%-50%, after entering ventilation cabinet 1 with the cooling fresh water of steam and air by the first pipeline 6, due to thermal expansion and buoyancy, steam and air enter warning chamber 2 by ventilation cabinet 1 top, again through ventilative pipeline 7 through swelling water cabinet 3 fast, in expansion water tank 3, steam is condensed liquefaction, air overflows from the permeability cell of expansion water tank 3, simultaneously, expansion water tank 3 supplements cooling fresh water to ventilation cabinet 1 by water return pipeline 4, substantially reduce steam and the waiting time of air in main frame cooling system of fresh water, improve cooling effect.Wherein, in order to breathe freely better, the ventilative pipeline 7 being communicated with the outlet in warning chamber 2 and the import of expansion water tank 3 need be positioned at the peak of main frame cooling system of fresh water, the middle and lower part of expansion water tank 3 received by ventilative pipeline 7, wherein the water return pipeline 4 of the water of expansion water tank 3 introducing ventilation cabinet 1 is also positioned at 5 ~ 10 ㎝ places below ventilative pipeline 7 interface, usually can be full of water in such warning chamber 2 and ventilation cabinet 1, be conducive to gas overflow from ventilation cabinet 1 after moisturizing at any time.
Owing to the water of expansion water tank 3 to be introduced the water return pipeline 4 in ventilation cabinet 1, ease off the pressure can also to the first pipeline 6 and return pipe 5 simultaneously, play buffer function.In addition, control pipeline for convenience, each pipeline is respectively arranged with common butterfly valve.Finally, by self running moved in circles, discharge the water vapor in water-cooling tube and air, serve permeation functions, efficiently solve ME EFI main frame because reducing operating mode to run in the cooling system of fresh water that causes in fresh water vaporization and fresh water air overflow a difficult problem for the reduction of cooling system cooling effect, cylinder sleeve corrosion etc. caused.
