Abstract
The utility model discloses a kind of for the cooler built-in hydraulic device in powder by atomization equipment, comprise hydraulic oil container, the oil hydraulic pump group be arranged on hydraulic oil container, the cooler that is arranged on the pressure gauge in oil hydraulic pump group and is arranged in fuel tank, the return opening of oil hydraulic pump group is communicated with cooler by return tube, cooler is provided with cooling water inlet pipe and cooling water outlet pipe, cooler is provided with the oil outlet tube being back to fuel tank for hydraulic oil after cooling water drainage cooling.Compared with existing hydraulic system, water-cooled tubular heat exchanger is placed in fuel tank internal by the utility model, during Hydraulic System Oil pump work, hydraulic oil is by heat exchanger and cooling water heat exchange, also add the heat exchange between heat exchanger outer surface and hydraulic oil, add heat exchange area, heat exchange efficiency is high; And when hydraulic system oil pump quits work, hydraulic oil also by the outer surface of heat exchanger and cooling medium heat exchange, can improve the utilization ratio of heat exchanger.
Description
Technical field
The utility model relates to hydraulic transmission technology field, particularly a kind of for the cooler built-in hydraulic device in powder by atomization equipment.
Background technique
Hydraulic station is also known as hydraulic power unit, generally rotated by driven by motor oil pump, oil pump is from fuel tank after oil suction repress oil, be the pressure energy of hydraulic oil by changes mechanical energy, hydraulic oil is flowed out by integrated package, after achieving direction, pressure, Flow-rate adjustment by hydrovalve again, in the oil cylinder being transferred to hydraulic machinery through external pipeline or oil motor, thus control the speed of the conversion in hydraulic motor direction, the size of strength and speed, promote the acting of various hydraulic machinery, use in a lot of field, for production and operation provide conveniently.Realization due to powder by atomization equipment automatic control system has many dependence hydraulic systems to realize, and hydraulic system operationally can produce a large amount of heats, causes oil temperature to raise, pressure drop, accelerates hydraulic pressure oil deterioration, inefficacy.In order to address this problem, generally install water-cooled tubular heat exchanger or air-cooled radiator additional, and all there is a common problem in these sinks, be exactly that oil flows through radiator, could dispel the heat only when operation of oil pump, and once oil pump quits work, even if oil temperature is high again, also cannot dispel the heat, sometimes even can affect the normal operation of atomization plant.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of when hydraulic system oil pump quits work, still can to hydraulic oil heat exchange cooling for the cooler built-in hydraulic device in powder by atomization equipment.
The utility model adopts following technological scheme: a kind of for the cooler built-in hydraulic device in powder by atomization equipment, comprises hydraulic oil container, the oil hydraulic pump group be arranged on hydraulic oil container, the cooler that is arranged on the pressure gauge in oil hydraulic pump group and is arranged in fuel tank;
The return opening of described oil hydraulic pump group is communicated with cooler by return tube;
Described cooler is provided with the cooling water intake being connected with cooling water inlet pipe and the coolant outlet being connected cooling water outlet pipe;
Described cooler is provided with the oil outlet tube being back to fuel tank for hydraulic oil after cooling water drainage cooling.
Described cooler is for installing water-cooled tubular heat exchanger additional.
Good effect of the present utility model is as follows: compared with existing hydraulic system, water-cooled tubular heat exchanger is placed in fuel tank internal by the utility model, be dipped in hydraulic oil, during Hydraulic System Oil pump work, hydraulic oil by heat exchanger and cooling water heat exchange, except the same with original heat exchange working state, also add the heat exchange between heat exchanger outer surface and hydraulic oil, not changing under contour size of the unit(s) prerequisite, add heat exchange area, heat exchange efficiency is higher than the past; And when hydraulic system oil pump quits work, hydraulic oil also by the outer surface of heat exchanger and cooling medium heat exchange, can improve the utilization ratio of heat exchanger, and then improves heat exchange efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, 1 fuel tank, 2 oil hydraulic pump groups, 3 pressure gauges, 4 coolers, 5 return tubes, 6 cooling water inlet pipes, 7 cooling water outlet pipes.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in accompanying drawing 1, a kind of for the cooler built-in hydraulic device in powder by atomization equipment, comprise hydraulic oil container 1, the oil hydraulic pump group 2 be arranged on hydraulic oil container 1, the cooler 4 that is arranged on the pressure gauge 3 in oil hydraulic pump group 2 and is arranged in fuel tank 1, the return opening of oil hydraulic pump group 2 is communicated with cooler 4 by return tube 5; Cooler 4 is provided with the cooling water intake being connected with cooling water inlet pipe 6 and the coolant outlet being connected cooling water outlet pipe 7, cooler 4 is provided with the oil outlet tube 8 being back to fuel tank 1 for hydraulic oil after cooling water drainage cooling.Cooler 4 is for installing water-cooled tubular heat exchanger additional.Due to cooler 4 is arranged in fuel tank 1, not only when Hydraulic System Oil pump work, hydraulic oil is by the heat exchange of tubular heat exchanger cooling water, also add the heat exchange between heat exchanger outer surface and hydraulic oil, do not changing under contour size of the unit(s) prerequisite, add heat exchange area, improve heat exchange efficiency; And when hydraulic system oil pump quits work, hydraulic oil also by the outer surface of heat exchanger and cooling medium heat exchange, can improve the utilization ratio of heat exchanger, accelerates hydraulic oil cooling efficiency, improves the Security of hydraulic station work.
The above mode of execution is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change that it is made under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
