The following describes the operation of the engine oil self-cleaning system of the present embodiment:
(1) oil and gas emission process
In the running process of an engine, a large amount of high-temperature mixed oil gas is generated in the oil pan 1, the oil pan 1 is communicated with the auxiliary oil tank 2 through the high-temperature mixed oil gas pipe 303, the high-temperature mixed oil gas in the oil pan 1 flows to the auxiliary oil tank 2 through the high-temperature mixed oil gas pipe 303 and is cooled down on the inner wall of the auxiliary oil tank 2, cooled engine oil is separated from air and is adhered to the inner wall of the auxiliary oil tank 2, or the engine oil cooled under the action of gravity is deposited at the bottom of the auxiliary oil tank 2, and preliminary oil-gas separation is completed; the remaining mixed oil and gas enters an oil and gas filter 302 (oil and gas separator) through the exhaust pipe 301 to be separated again, and then the re-separated oil will flow back into the auxiliary oil tank 2 along the exhaust pipe 301 to be deposited at the bottom of the auxiliary oil tank 2, while the exhaust gas is discharged to the atmosphere through the exhaust pipe 301.
Through above-mentioned oil-gas separation process, the high temperature mixed oil gas in the oil pan 1 is through the first separation of tank wall refrigerated and oil-gas separator's secondary separation, can reduce the machine oil content in the waste gas by a wide margin, reduce the environmental pollution that machine oil volatilizees and cause, the machine oil that flows back to auxiliary engine oil case 2 moreover can also carry out reuse, thereby reduce the machine oil loss, reduce machine oil use cost, and simultaneously, the carbon deposit of the engine burning that contains in the high temperature mixed oil gas, the dust, impurity such as fatlute, leave in auxiliary engine oil case 2 along with the machine oil that separates, and can not get into in the oil pan 1, thereby realize the cleanness to oil pan 1, make the machine oil purity in the oil pan 1 higher, can effectively promote the lubricated effect of machine oil to the engine in the oil pan.
(2) Pressure relief process
At the initial stage of engine starting, because the engine oil temperature is low, the viscosity is high, and the pressure is high, a part of the engine oil in the oil pan 1 is discharged and flows out through the oil passage on-off control piece 402 (oil pump overflow valve). Overflow pipe 401 intercommunication oil pump overflow valve and supplementary machine oil case 2, the machine oil that the overflow came out will flow to supplementary machine oil case 2, realizes the pressure release, and these contain impurity more in the machine oil of oil pan 1 bottom moreover, the machine oil of oil pan 1 bottom will be earlier through overflow pipe 401 flow direction supplementary machine oil case 2 to will reserve and deposit in the bottom of supplementary machine oil case 2, thereby avoid the impurity circulation in the machine oil to flow back to oil pan 1, influence the machine oil cleanliness in the oil pan 1.
(3) Oil reflux process (oil replenishment process)
As shown in fig. 2, the liquid level detection elements 6 installed in the oil pan 1 and the auxiliary oil tank 2 can detect the oil level values in the oil pan 1 and the auxiliary oil tank 2, and can grasp the oil consumption and storage in time. The controller 7 automatically identifies the oil level states of the oil pan 1 and the auxiliary oil tank 2, and after the set conditions are met, sends out control signals to open the electromagnetic valve 504 and the power extraction part 503 respectively, and the waste oil collected in the auxiliary oil tank 2 is filtered by the oil filter part 502 and then is filled into the oil pan 1 under the action of the power extraction part 503, so that the oil supplement to the oil pan 1 is realized. The method comprises the following specific steps:
firstly, starting;
secondly, a liquid level detecting element 6 in the auxiliary engine oil tank 2 detects the liquid level value L in the auxiliary engine oil tank 2 2 ；
Third, judge the level value L of the auxiliary engine oil tank 2 Whether or not it is greater than or equal to its highest value, i.e. L 2 Whether or not it is greater than or equal to L 2max Wherein L is 2max The preset value can be set according to specific use conditions;
if not, returning to the step II;
if yes, the liquid level detecting element 6 in the oil pan 1 detects the liquid level value L in the oil pan 1 1 ；
Sixthly, judging the liquid level value L in the oil pan 1 1 Whether or not it is less than or equal to its lowest value, i.e. L 1 Whether or not it is less than or equal to L 1min Wherein L is 1min The preset value can be set according to specific use conditions;
if not, returning to the fifth step;
if yes, opening the electromagnetic valve 504, opening the power extraction part 503, and replenishing the engine oil to the oil pan 1;
ninthly judging oil panLevel value L within 1 1 Whether or not it is greater than or equal to its highest value, i.e. L 1 Whether or not it is greater than or equal to L 1max Wherein L is 1max The preset value can be set according to specific use conditions;
if not, returning to the step (b);
The oil backflow process is completed, namely the oil in the oil pan is supplemented.
This embodiment still provides an engine system, including the engine and the machine oil automatically cleaning system of this embodiment, this kind of engine system can obviously reduce the impurity in the engine oil pan, reduces the accumulation of machine oil filth in the oil pan, prolongs the life that machine oil strained, reduces the change number of times that machine oil strained, reduces the maintenance cost, moreover because impurity in the engine oil pan is less, engine system's lubricated effect is better, makes engine system not fragile, guarantees the long-time normal use of engine.
The embodiment also provides an operating machine, including the engine system of this embodiment, because the impurity of this engine system internal oil pan is less, needn't often change machine oil and strain to reduce operating machine's maintenance number of times, practice thrift cost of maintenance, engine system's lubricated effect is better moreover, and is not fragile, is favorable to ensureing operating machine's long-time operation.
In other embodiments, the auxiliary oil tank 2 may be disposed at a position not higher than the oil pan 1, for example, the auxiliary oil tank 2 may be disposed at a position flush with the oil pan 1, or the auxiliary oil tank 2 may be disposed at a position lower than the oil pan 1, so that the oil in the oil pan can be replenished by disposing the drawing power member 503 on the oil return pipe 501. Of course, the auxiliary oil tank 2 may be still higher than the oil pan 1, but the oil return pipe 501 is not provided with the power extraction member 503, and the engine oil flows from the auxiliary oil tank 2 to the oil pan 1 only under the action of gravity of the engine oil, so that the purpose of engine oil replenishment can be achieved, and the equipment cost can be saved.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
