Preferably, in technique scheme, observe lid and be made up of organic glass or plastics.
Compared with prior art, the utility model has following beneficial effect:
Measurement mechanism structure of the present utility model is simple, cheap for manufacturing cost, avoids measurement mechanism to take very large installing space; And easy to use, quick and precisely can read the volume of the air in liquid coolant, the convenient air content calculated in liquid coolant.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the measurement mechanism according to the air content in the liquid coolant of engine of the present utility model.
Main Reference Numerals illustrates:
1-engine, 2-rising pipe, 3-observes lid, 4-thermostat, 5-heating radiator, 6-water inlet pipe, 7-partial circulating water pipe.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1, comprise rising pipe 2 according to the measurement mechanism of the air content in the liquid coolant of the engine of the utility model embodiment, observe lid 3, water inlet pipe 6, heating radiator 5, partial circulating water pipe 7 and thermostat 4.
Be provided with water cavity (flow channel of liquid coolant) in engine 1, the water delivering orifice of water cavity is communicated with water inlet pipe 6 with rising pipe 2 respectively with water inlet, and rising pipe 2 is communicated with water delivering orifice with the water inlet of heating radiator 5 respectively with the other end of water inlet pipe 6.Heating radiator 5 for cooling liquid coolant, and sends cooled liquid coolant back to engine 1.
The middle part of rising pipe 2 is provided with the first partial circulating interface, and the middle part of water inlet pipe 6 is provided with the second partial circulating interface, is provided with partial circulating water pipe 7, first partial circulating interface and is provided with thermostat 4 between the first partial circulating interface and the second partial circulating interface.When the temperature of liquid coolant is lower, do not need the cooling of heating radiator 5, now thermostat 4 cuts out, block the connection between the water delivering orifice of engine 1 and heating radiator 5, make rising pipe 2 be communicated with partial circulating water pipe 7 simultaneously, the now water outlet of engine 1 directly flows to water inlet pipe 6 by partial circulating water pipe 7, and then enter in engine 1 carry out inner loop (without heating radiator 5, be conducive to coolant temperature low time being rapidly heated of engine); When the temperature of liquid coolant is higher, thermostat 4 is opened, and blocked the connection of rising pipe 2 and partial circulating water pipe 7, meanwhile, rising pipe 2 is communicated with heating radiator 5, and now high temperature coolant flows in heating radiator 5 by rising pipe 2, flows back to engine 1 again after cooling.
Observe lid 3 to be arranged between the water delivering orifice of engine and the first partial circulating interface, and be positioned at the highest point of rising pipe 2, make the upward motion of air run out of in liquid coolant and accumulate in observe in lid 3.As an embodiment, as described in Figure 1, position rising pipe 2 is connected with the water delivering orifice of engine is lower than the installation site observing lid 3.The lateral surface observing lid 3 is provided with limit value warning line and many scale mark (not shown)s.
Preferably, the shape of lid 3 in semisphere, column, taper or semiellipse ball is observed.Preferably, observe lid 3 to be made up of organic glass or plastics.
During engine running, under high pressure and high flow rate, observe in lid 3 and be full of liquid coolant.When after engine stop running, liquid coolant also stops flowing.In the process left standstill, the bubble in engine water cavity slowly can float to the ullage of liquid coolant, finally accumulates in the top of liquid coolant cavity volume, namely observes in the inner chamber of lid.After the standing schedule time, bubble is run out of completely from liquid coolant, then reads the scale corresponding to liquid level observing liquid coolant in lid, can draw the volume accumulating in the air observed in lid.Then the quality m of described air is calculated according to the computing formula m=ρ v of the Ideal-Gas Equation PV/T=C and quality
1, divided by the gross mass m of liquid coolant in engine water cavity
2, according to formula A=m
1/ m
2just can draw the air content A in liquid coolant.Preferably, the time that shutdown leaves standstill is more than or equal to 0.5 hour.
Volume due to the water cavity of the liquid coolant of engine is fixing, namely the cumulative volume of in-engine liquid coolant and gross mass are fixing (generally calculating according to the design load of engine water cavity), without the need to the specific discharge of use traffic measurement amount liquid coolant, with the gross mass of the liquid coolant in calculation engine; Whether air content is too much simultaneously, the liquid level only need observing liquid coolant whether exceed observe the limit value warning line covering sign can (concrete scale mark position need be determined by actual measurement, the calculating etc. such as geomery, volume of covering according to the observation during development experiments), without the need to equipment such as special air collecting device and graduated cylinders, also without the need to calculating in detail the volume of air in use.
When using measurement mechanism of the present utility model, by observing the scale accumulating in the air capacity of observing in lid, just can know the air content of liquid coolant; Whether exceeding limit value warning line by observing the air capacity accumulated in observation lid 3, can know that whether liquid coolant air content is qualified.
Measurement mechanism structure of the present utility model is simple, cheap for manufacturing cost, avoids measurement mechanism to take very large installing space; And easy to use, quick and precisely can read the volume of the air in liquid coolant, the convenient air content calculated in liquid coolant.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
