Description
Technical field
It the utility model is related to a kind of oil temperature circulating cooling warning device for hydraulic system.
Background technology
Hydraulic oil is transmitting medium in hydraulic system, and its effect can not be substituted in hydraulic work system, but work as hydraulic oil
Flow velocity it is too high or because flow resistance it is excessive when oil temperature can be caused drastically to raise, but oil temperature reach certain temperature in the case of not only can
Increase the leakage at Hydraulic Elements sealing, but also potted component can be made to fail, make the service life reduction of the elements such as rubber oil hose,
Therefore it is essential to hydraulic system to give operator's reminding alarm device when the oil temperature of hydraulic oil exceedes setting.It is existing
The detection of hydraulic oil oil temperature is mainly oil thermometer, is detected using the principle of mercury heat expansion, because it is arranged on the middle and lower part of fuel tank
Observation is inconvenient, and does not have warning function.Also, when oil liquid temperature of the existing hydraulic system in fuel tank is too high, without one
The individual mode that cools well.It can be seen that the cooling measure of fuel tank is just into having asked a kind of urgent problem to be solved.
Utility model content
The purpose of the utility model is that a kind of hydraulic oil high-temperature alarming device is provided the defects of presence for prior art, makes liquid
When the oil temperature of force feed exceedes my setting, device, which returns, continuously sends alarm, prompts operator to detect hydraulic system, and this covering device
Power supply is not needed.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of oil temperature for hydraulic system circulates
Warning device, including oil tank body are cooled down, is provided with coil pipe on the oil tank body inwall, the input of the coil pipe is by following
The delivery outlet of ring pump and cooler bin connects, and the output end of the coil pipe and the input port of cooler bin connect；Also include thermo-electric generation
Piece, its cathode output end are connected by the first wire with adjustable resistance, and are connected by the adjustable resistance with warning device end,
The cathode output end of the thermo-electric generation sheet is connected by the second wire with the warning device other end；Wherein, the warning device
Both ends be also parallel with a relay, the control output end of the relay is connected with the control signal of the circulating pump.
Preferably, the thermo-electric generation sheet by thermally conductive sheet, power generation sheet and groups of fins into.
The beneficial effects of the utility model：The utility model can take into account oil simultaneously when oil liquid temperature is too high in fuel tank
Temperature alarm and the operation for fluid cool down circulation temperature lowering, it is high without manual control, automaticity during being somebody's turn to do.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of oil temperature circulating cooling warning device for hydraulic system, including oil tank body 4, it is described
Coil pipe 5 is provided with the inwall of oil tank body 4, the input of the coil pipe 5 is connected by circulating pump 6 with the delivery outlet of cooler bin 7,
The output end of the coil pipe 5 is connected with the input port of cooler bin 7；Also include thermo-electric generation sheet 1 (thermo-electric generation sheet by thermally conductive sheet,
Power generation sheet and groups of fins), its cathode output end is connected by the first wire 31 with adjustable resistance 2, and passes through the adjustable electric
Resistance 2 is connected with the one end of warning device 3, and the cathode output end of the thermo-electric generation sheet 1 is another by the second wire 32 and warning device 3
One end connects；Wherein, the both ends of the warning device 3 are also parallel with a relay 8, the control output end of the relay 8 with
The control signal connection of the circulating pump 6.
In use, the thermally conductive sheet of thermo-electric generation sheet 1 is securely attached to the oil return profile height of oil tank body 4 with heat-conducting glue
A quarter at；When the hydraulic oil liquid temperature rise in oil tank body 4, the side plate of oil tank body 4 is delivered to using fluid
Temperature make thermo-electric generation sheet 1 both sides (both thermally conductive sheet and fin) produce temperature difference so that thermo-electric generation sheet 1 produce electric current,
So as to control warning device 3 can be made to send sound report at a predetermined temperature by adjusting the big minor adjustment electric current of adjustable resistance 2
It is alert.Simultaneously as thermo-electric generation sheet 1 generates electric current, and the coil electricity in relay 8, the normally opened contact closure of relay 8,
Relay 8 controls circulating pump 6 to connect external power source, and circulating pump 6 works, and the coolant in cooler bin 7 is extracted out and enters disk
Heat exchange is carried out in pipe 5, cooling processing is carried out to the fluid in fuel tank by coil pipe 5, at the same the coolant after absorbing heat circulate into
Enter into cooler bin 7.When the oil liquid temperature in oil tank body 4 is less than the operating temperature of thermo-electric generation sheet 1, thermo-electric generation sheet 1
Also just without electric current, now, the stop alarm of warning device 3, relay 8 is stopped.
Oil temperature warning device of the present utility model for hydraulic system can under hydraulic system normal operating conditions (oil temperature
No more than set-point) warning device do not send sound, enters when the fluid of fuel tank sends sound more than set point of temperature Times alarm device
Row alarm；Also, by the circulating cooling system of setting, quick circulating cooling cooling can be carried out to fuel tank, prevent hydraulic pressure
Potted component failure in system, substantially increase the service life of the elements such as rubber oil hose.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
