Abstract
A kind of return tube with cooling unit, it comprises return tube, return tube is inlaid with water cavity, water cavity is provided with temperature indicating meter, and water cavity wall is provided with water intake and water outlet, and stifled respectively on water intake and water outlet have into water plug and water plug, water cavity is alloy cavity, the thickness of cavity wall is 10 millimeters to 15 millimeters, is provided with every photosphere at water cavity outer surface, and the wall thickness that return tube is positioned at water cavity part is 1 millimeter to 3 millimeters.The utility model can solve oil temperature when getting back to fuel tank, the problem of high oil temperature.
Description
Technical field
The utility model relates to hydraulic system, is specifically related to hydraulic station oil-return pipeline system.
Background technique
Hydraulic station is a kind of device of position fuel feeding machinery being needed to lubrication, in hydraulic station lubrication system, must ensure that oil temperature is in suitable temperature, if high oil temperature, oil pressure can be made to reduce, thus cause fuel delivery not enough, time serious, can equipment accident be caused; During the work of conventional hydraulic station, hydraulic station system has only installed panel cooler, the lubricant oil in oil inlet pipe can only be cooled, but the lubricant oil flowed out through return tube from lubricant housings often has very high temperature, so the temperature of getting back to the oil of fuel tank is very high, due to panel cooler limited efficiency, the high temperature oil in fuel tank by transport pump to oil inlet pipe, after panel cooler cooling, oil temperature is still not ideal enough.
Model utility content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of return tube with cooling unit provided, and it can solve oil temperature when getting back to fuel tank, the problem of high oil temperature.
The object of model utility is achieved in that
A kind of return tube with cooling unit, it comprises return tube, return tube is inlaid with water cavity, water cavity is provided with temperature indicating meter, and water cavity wall is provided with water intake and water outlet, and stifled respectively on water intake and water outlet have into water plug and water plug, water cavity is alloy cavity, the thickness of cavity wall is 10 millimeters to 15 millimeters, is provided with every photosphere at water cavity outer surface, and the wall thickness that return tube is positioned at water cavity part is 1 millimeter to 3 millimeters.
Above-mentioned water cavity is aluminium alloy cavity, and cavity wall thickness is 12 millimeters, is white paint layer every photosphere.
The part wall thickness of above-mentioned return tube in water cavity is 2 millimeters, and crossfades into ellipse in water cavity.
The aluminum alloy material specific heat capacity that water cavity adopts is comparatively large, and water cavity wall thickness is thicker, is that the heat in water cavity absorbing environmental makes water cavity temperature uprise very soon in order to prevent under summer high temperature environment, and then causes water temperature in chamber to raise; Water cavity outer surface is set as white paint layer every photosphere, is because white not extinction, is also to prevent heating after water cavity extinction.
That is designed by the part wall thickness of return tube in water cavity is thinner, is to You Heshui be made faster to carry out heat exchange, the part of return tube in water cavity is crossfaded into ellipse, is the heat exchange area in order to increase oil and water, better cooling down high-temperature lubricant oil.
Adopt said structure, when high temperature oil is through return tube, can be pre-cooled in water-filled water cavity, and then get back to fuel tank, the oil temperature of now getting back in fuel tank can decline, again during fuel feeding, because initial oil temperature is not high, enter oil inlet pipe after panel cooler cooling, can ensure that the oil temperature entering lubricant housings is in rational scope; This apparatus structure is simple, easy to operate, only need determine whether change cooling water according to the registration on temperature indicating meter, when cooling water changed by needs, change water, if in the winter time by water intake and water outlet, in return tube oil temperature not high do not need cooling time, the water in emptying water cavity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of return tube in the utility model water cavity.
Embodiment
A kind of return tube with cooling unit as shown in Figure 1, it comprises return tube 1, return tube 1 is inlaid with water cavity 2, water cavity 2 is provided with temperature indicating meter 7, and water cavity 2 wall is provided with water intake 5 and water outlet 4, and stifled respectively on water intake 5 and water outlet 4 have into water plug 6 and water plug 3, water cavity 2 is alloy cavity, the thickness of cavity wall is 10 millimeters to 15 millimeters, is provided with every photosphere at water cavity 2 outer surface, and the wall thickness that return tube 1 is positioned at water cavity 2 part is 1 millimeter to 3 millimeters.
Described water cavity 2 is aluminium alloy cavity, and cavity wall thickness is 12 millimeters, is white paint layer every photosphere.
The part wall thickness of described return tube 1 in water cavity 2 is 2 millimeters, and crossfades into ellipse in water cavity 2.
The aluminum alloy material specific heat capacity that water cavity adopts is comparatively large, and water cavity wall thickness is thicker, is that the heat in water cavity absorbing environmental makes water cavity temperature uprise very soon in order to prevent under summer high temperature environment, and then causes water temperature in chamber to raise; Water cavity outer surface is set as white paint layer every photosphere, is because white not extinction, is also to prevent heating after water cavity extinction.
That is designed by the part wall thickness of return tube in water cavity is thinner, is to You Heshui be made faster to carry out heat exchange, the part of return tube in water cavity is crossfaded into ellipse, is the heat exchange area in order to increase oil and water, better cooling down high-temperature lubricant oil.
Adopt said structure, when high temperature oil is through return tube, can be pre-cooled in water-filled water cavity, and then get back to fuel tank, the oil temperature of now getting back in fuel tank can decline, again during fuel feeding, because initial oil temperature is not high, enter oil inlet pipe after panel cooler cooling, can ensure that the oil temperature entering lubricant housings is in rational scope; This apparatus structure is simple, easy to operate, only need determine whether change cooling water according to the registration on temperature indicating meter, when cooling water changed by needs, change water, if in the winter time by water intake and water outlet, in return tube oil temperature not high do not need cooling time, the water in emptying water cavity.
