Description
Technical field
The present invention relates to machine testing technical field, is specifically a kind of for the machine oil aerating device in lubricating oil pump proving installation.
Background technology
Operationally, each moving parts is all used on another part with certain masterpiece motor car engine, and relative motion at a high speed occurs, and had relative motion, piece surface must produce friction, thus accelerated wear test.Therefore, in order to alleviate wearing and tearing, reducing frictional resistance, increasing the service life, engine all must have on lubricating system components.The various equipment such as the organic oil pump of critical piece of lubricating system, the effect of lubricating oil pump is after machine oil is brought up to certain pressure, is sent to forcibly on the moving surface of each part of engine.
In the actual use procedure of engine, the machine oil of engine has certain air content, this is because engine operation machine oil is got back to along casing wall and is had a small amount of gas in the oil return process of oil sump and enter machine oil and be mixed in wherein from cylinder cap, and the gas be mixed in machine oil can cause various adverse influence to the part in engine, such as can bearing in corrode engine.And in order to avoid this adverse effect as much as possible, in industry, engine motor oil is provided with to the requirement of air content.In prior art, in lubricating oil pump, the proving installation of air content generally includes air pump and tracheae, the two ends of tracheae connect the fuel tank at the oil-in place of air pump and lubricating oil pump respectively, like this, the gas got from air pump is conveyed in fuel tank by tracheae, makes gas dissolution in fluid, when fuel tank is to lubricating oil pump fuel feeding, gas just enters in lubricating oil pump, and passes through the output pressure of test machine oil pump, thus the runnability of test engine.And for example disclosed CN203705440U patent " for measuring the device of engine motor oil air content " on State Intellectual Property Office website, it comprise the volume for measuring engine motor oil measurer and for being connected to engine motor oil oil circuit and engine motor oil oil circuit being incorporated into the connecting pipe in measurer.The machine oil of operating engine is first incorporated in measurer by it, and record temperature and the volume of the machine oil be now incorporated in measurer, through after a while, after standby oil cooling gas but and wherein departs from machine oil, again again record temperature and the volume of the machine oil in measurer, finally utilize formulae discovery to draw the air content of engine motor oil, thus accurately record the air content of engine motor oil.
But the proving installation Problems existing of these engine motor oil air contents above-mentioned is:
1) for the former, after gas is conveyed into fuel tank by tracheae by air pump, make gas dissolution in fluid, but, the distribution of gas in fluid is uneven, can be high at the junction gas content of tracheae and fuel tank, and it is more lower away from junction gas content, therefore, to be supplied to the machine oil of lubricating oil pump gas content from fuel tank uniform, and the output pressure of lubricating oil pump raises along with the minimizing of gas content, like this, lubricating oil pump can not stably output pressure, is reflected on engine, just can not reflects the behaviour in service of engine really;
2) and for the latter, it is a kind of difference of volume change of the fluid contrasted under deep fat liquid and normal temperature purely, and is calculated the air content in engine motor oil by certain computing method, and therefore, its detection efficiency is too low, and error is larger.
Summary of the invention
Technical matters to be solved by this invention is, provides one that gas can be made fully to be dissolved in fluid, thus the data that test is drawn are more accurately for the machine oil aerating device in lubricating oil pump proving installation.
For solving the problems of the technologies described above, provided by the invention for the machine oil aerating device in lubricating oil pump proving installation, comprise air pump, for lubricating oil pump oil-in fuel feeding fuel tank and be communicated with the tracheae of air pump and fuel tank; It also comprises dividing plate, and described dividing plate is provided with multiple through hole being covered with whole dividing plate, and the edge conjunction of dividing plate on the madial wall of fuel tank, and is positioned at and passes into port near tracheae.
Described tracheae and the connectivity port of fuel tank are positioned at the bottom of fuel tank, and dividing plate and tank bottoms have chamber, and this chamber is air storage chamber.
Through hole on described dividing plate is axially extending bore, and in honeycomb arrangement between through hole and through hole.
Through hole on described dividing plate is taper hole, and one end that wherein diameter dimension is little is towards fluid, and the large one end of diameter dimension passes into end towards tracheae.
Described dividing plate is be arranged in parallel two-layer, and the through hole in upper partition and the through hole in lower partition are crisscross arranged.
Described dividing plate is the sheet material that nonmetallic materials are made, and the edge of dividing plate is bonding with the madial wall of fuel tank, and wherein the formula of bonding agent is:
After adopting above structure, the present invention compared with prior art, has following advantage:
1) owing to being provided with dividing plate in fuel tank, and dividing plate is provided with multiple densely covered through hole, like this, the gas of air pump conveying is sent in the fluid in fuel tank by these through holes, and the through hole of whole dividing plate is covered with by these, gas is made more evenly to be mixed in fluid, in other words, gas content in fluid is uniform, there will not be at the junction gas content of tracheae and fuel tank high, and it is more lower away from junction gas content, therefore, lubricating oil pump can more stably output pressure, be reflected on engine, more can reflect the behaviour in service of engine really,
2) after dividing plate and tank bottoms are provided with air storage chamber, make gas from tracheae out after first all can contact the area of dividing plate, like this, through holes all on dividing plate is all by gas, therefore, mixedly more even in fluid of gas, ensures to test the data that draw further close to truth;
3) on dividing plate, the axis of through hole is arranged and cellular setting, and the cross-sectional area of through hole on dividing plate is maximized, and like this, makes the quick comprehensive engagement fluid again of gas as much as possible, makes gas and vapor permeation more even in the machine oil air content of fluid;
4) on dividing plate, the taper hole of through hole is arranged, and makes the gas in air storage chamber lead to all rapidly taper hole one end of larger diameter end, and through taper hole one end of smaller diameter end, slow down the mixing velocity of gas, gas can more effectively be mixed with fluid;
5) the two-layer setting of dividing plate in fuel tank, and the through hole of upper partition and lower partition is interspersed, and makes gas be mixed into fluid fully from each corner of tank bottoms, ensure that fuel tank inner fluid is more balanced with the mixing of gas further.
