Fig. 2 is the structural representation of the liquid level liquid thermometer that is used for hydraulic system of the utility model preferred embodiment.
Fig. 3 is the structural representation of the liquid level gauge that is used for hydraulic system of the utility model second embodiment.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment; To the liquid level liquid thermometer that is used for hydraulic system that proposes according to the utility model and embodiment, structure, characteristic and the effect thereof of liquid level gauge, specify as follows:
Aforementioned and other technology contents, characteristics and the effect of relevant the utility model can be known to appear in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation through embodiment; When can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model; Yet the appended graphic usefulness that only provides reference and explanation is not to be used for the utility model is limited.
Please with reference to shown in Figure 2, the liquid level liquid thermometer 10 that is used for hydraulic system of the utility model embodiment comprises panel 12, and the liquid level tube (figure is mark not) that is arranged on panel 12 rears.Upper/lower terminal at panel 12 is provided with fixed part 14, offers fixed orifice 142 at each fixed part 14, can liquid level liquid thermometer 10 be fixed on engineering machinery or the engineering truck through screw etc. being passed the fixed orifice 142 of fixed part 14.Be provided with view window 16 at the middle part of panel 12, view window 16 is by transparent material, and for example glass etc. is processed, and therefore the liquid level tube of part can expose from view window 16 at least.
The hydraulic reservoir (figure do not show) of storage hydraulic oil forms linker in liquid level tube and the hydraulic system, thereby the interior liquid level of the height of the liquid level 13 in the liquid level tube and hydraulic reservoir is identical, thereby can measure the liquid level of hydraulic reservoir.In liquid level tube, be provided with liquid thermometer 18, liquid thermometer 18 is fixed on the rear wall in the liquid level tube, promptly in the liquid level tube apart from view window 16 wall far away, its lower end is stretched under the liquid level 13 of hydraulic oil, thereby can measure the temperature of hydraulic oil.In liquid level tube, also be provided with buoy 132, shape such as buoy 132 can be spherical, and is perhaps cylindrical, its diameter or length, promptly its full-size is less than the diameter of liquid level tube.Buoy 132 is processed less than the material of hydraulic oil by proportion, less plastics of proportion for example, thus buoy 132 can float on the liquid level 13 of hydraulic oil.Buoy 132 is preferably the comparison chromatic colour, and is for example red.
Like this, see through view window 16, the observer both can see the height of the liquid level 13 in the liquid level tube, and promptly liquid level can be seen the temperature indication on the liquid thermometer 18 again.And owing in liquid level tube, also be provided with buoy 132, and buoy 132 floats all the time on the liquid level 13 of hydraulic oil, makes the observer can be easily and observably observe the height of buoy 132, the i.e. height of hydraulic oil liquid level 13 in the liquid level tube.Buoy 132 is set, increases the cost of liquid level liquid thermometer 10 hardly, but can obtain good effect, and do not need to safeguard.
Please with reference to shown in Figure 3, in second embodiment of the utility model, other element all with first embodiment in identical, difference is, liquid thermometer is not set in liquid level tube.It is the liquid level that liquid level gauge 20 only is used to measure hydraulic system.
The liquid level gauge 20 that is used for hydraulic system comprises panel 22 equally, and the liquid level tube (figure is mark not) that is arranged on panel 22 rears.Upper/lower terminal at panel 22 is provided with fixed part 24, offers fixed orifice 242 at each fixed part 24.Be provided with view window 26 at the middle part of panel 22, view window 26 is by transparent material, and for example glass etc. is processed, thereby the liquid level tube of part can expose from view window 26 at least.
Liquid level tube same with hydraulic system in hydraulic reservoir (figure does not show) form linker, thereby the interior liquid level of the height of the liquid level 23 in the liquid level tube and hydraulic reservoir is identical.In liquid level tube, also be provided with buoy 232, shape such as buoy 232 can be spherical, and is perhaps cylindrical, its full-size is less than the diameter of liquid level tube.Buoy 232 is processed less than the material of hydraulic oil by proportion, thereby buoy 232 can float on the liquid level 23 of hydraulic oil.Buoy 232 is preferably the comparison chromatic colour, and is for example red.
Like this; See through view window 26; The observer can observe the height of the liquid level 23 in the liquid level tube, and owing in liquid level tube, also be provided with buoy 232, and buoy 232 floats all the time on the liquid level 23 of hydraulic oil; Make the observer can be easily and observably observe the height of buoy 232, the i.e. height of hydraulic oil liquid level 23 in the liquid level tube.Buoy 232 is set, increases the cost of liquid level liquid 20 hardly, but can obtain good effect, and do not need to safeguard.
The above only is the embodiment of the utility model, is not the utility model is done any pro forma restriction; Though the utility model discloses as above with embodiment; Yet be not in order to limiting the utility model, anyly be familiar with the professional and technical personnel, in not breaking away from the utility model technical scheme scope; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from the utility model technical scheme content, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
