Description
Technical field
The present invention relates to machine testing technical fields, are especially a kind of machine oil inflation dress in lubricating oil pump test device
It puts.
Background technology
At work, each moving parts are acted on certain power on another part automobile engine, and are occurred
The relative motion of high speed has relative motion, and piece surface must generate friction, so as to accelerated wear test.Therefore, in order to mitigate
Abrasion reduces frictional resistance, prolongs the service life, must all have on lubricating system components on engine.Lubricating system it is main
The various equipment such as the organic oil pump of component, the effect of lubricating oil pump are after machine oil is increased to certain pressure, are forcibly sent to and start
On the moving surface of each part of machine.
In engine in actual use, the machine oil of engine is that have certain air content, this is because hair
Machine oil, which is returned to from cylinder cap upper edge casing wall during the oil return of oil sump, in motivation operation has a small amount of gas and enters machine oil and press from both sides
It is miscellaneous wherein, and the part in engine can be caused various detrimental effects by being mixed in the gas in machine oil, for example can be corroded
Bearing in engine.And in order to be avoided as much as this adverse effect, air content is provided with to engine motor oil in industry
Requirement.In the prior art, the test device of air content generally includes air pump and tracheae in lubricating oil pump, and the both ends of tracheae connect respectively
The fuel tank at air pump and the oil inlet of lubricating oil pump is connect, in this way, the gas got from air pump is conveyed by tracheae in fuel tank, makes gas
Body is dissolved in fluid, and when fuel tank is to machine oil oil pump feed, gas has been put into lubricating oil pump, and by testing the defeated of lubricating oil pump
Go out pressure, so as to the runnability of test engine.For another example disclosed CN203705440U is special on State Intellectual Property Office website
Profit " for measuring the device of engine motor oil air content ", it include for measure engine motor oil volume measurer and use
In being connected to engine motor oil oil circuit and engine motor oil oil circuit be introduced into the connecting tube in measurer.It is first by running hair
The machine oil of motivation is introduced into measurer, and measures the temperature and volume for being introduced into the machine oil in measurer at this time, after a period of time,
Standby oil cooling is but and gas therein is detached from machine oil and then the secondary temperature and volume for measuring the machine oil in measurer again, most
The air content of engine motor oil is calculated using formula afterwards, so as to accurately measure the air content of engine motor oil.
But the test device of these above-mentioned engine motor oil air contents the problem is that：
1) for the former, after gas is conveyed into fuel tank by air pump by tracheae, gas is made to be dissolved in fluid, still, gas
Body being unevenly distributed in fluid, can be high in the junction gas content of tracheae and fuel tank, and further away from junction gas
Body content is lower, therefore, is supplied in the machine oil of lubricating oil pump gas content and non-uniform from fuel tank, and the output pressure of lubricating oil pump
Power is raised with the reduction of gas content, in this way, lubricating oil pump steadily output pressure, reflection can not arrive engine
On, it cannot really reflect the behaviour in service of engine；
2) and for the latter, it is purely a kind of difference for the volume change for comparing deep fat liquid and the fluid under room temperature, and
The air content in engine motor oil is calculated by certain computational methods, therefore, its detection efficiency is too low, and error
It is larger.
Invention content
Gas can be made fully to be dissolved into fluid the technical problem to be solved by the invention is to provide a kind of, so as to make survey
The data obtained are tried more accurately for the machine oil air charging system in lubricating oil pump test device.
In order to solve the above technical problems, provided by the present invention for the machine oil air charging system in lubricating oil pump test device, packet
Include air pump, for the fuel tank of lubricating oil pump oil inlet fuel feeding and connection air pump and fuel tank tracheae；It further includes partition board, described
Partition board be equipped with multiple through-holes for being covered with entire partition board, the edge of partition board is connected on the madial wall of fuel tank, and positioned at close
Tracheae is passed through at port.
The tracheae and the connectivity port of fuel tank are located at the bottom of fuel tank, and partition board has chamber with tank bottoms,
The chamber is air storage chamber.
Through-hole on the partition board is axially extending bore, and is in honeycomb arrangement between through-hole and through-hole.
Through-hole on the partition board is taper hole, wherein small one end of diameter dimension towards fluid, diameter dimension it is big one
End is passed through end towards tracheae.
The partition board is two layers be arranged in parallel, and the through-hole on the through-hole and lower partition in upper partition interlocks
Setting.
The partition board is plank made of nonmetallic materials, and the edge of partition board is Nian Jie with the madial wall of fuel tank, wherein viscous
The formula for connecing agent is：
After more than structure, compared with prior art, the present invention having the following advantages that：
1) due to being provided with partition board in fuel tank, and partition board is equipped with multiple densely covered through-holes, in this way, air pump conveying
Gas can be sent by these through-holes in the fluid in fuel tank, and is covered with the through-hole of entire partition board by these, is allowed gas to
More uniformly in fluid is mixed in, in other words, the gas content in fluid is uniform, does not appear in tracheae and fuel tank
Junction gas content it is high, and lower further away from junction gas content, therefore, lubricating oil pump can more steadily export pressure
Power reflects on engine, more can really reflect the behaviour in service of engine；
2) after partition board and tank bottoms are provided with air storage chamber, gas is made first all to contact partition board after being come out from tracheae
Area, in this way, through-hole all on partition board can be by gas, therefore, gas is mixedly more uniform in fluid, into one
Step ensures the data that obtain of test close to truth；
3) on partition board through-hole axial setting and cellular setting, maximize cross-sectional area of the through-hole on partition board, this
Sample makes the quick comprehensive engagement fluid again of gas, makes gas mixing more uniform in the machine oil air content of fluid as much as possible；
4) taper hole of through-hole is set on partition board, and the indoor gas of gas storage is made all to lead to taper hole one end of larger diameter end rapidly,
And taper hole one end Jing Guo smaller diameter end, the mixing velocity of gas is slowed down, allows gas to more effectively mix with fluid；
5) two layers setting of the partition board in fuel tank, and the through-hole of upper partition and lower partition is interspersed, and makes gas
Body is sufficiently mixed from each corner of tank bottoms into fluid, further ensure that the mixing of fuel tank inner fluid and gas more
Add equilibrium.
