Example one
As shown in fig. 1, an oil filling system of a large excavating or loading equipment engine of an embodiment includes an oil tank 10, a circulation line 20, a circulation pump 40, a liquid level detection device 50, and a filter device 60. Wherein the circulation line 20 is connected between the sump 10 and the oil pan 30 of the engine. The circulation pump 40 is provided on the circulation line 20. The liquid level detection device 50 is provided in the oil pan 30, and the circulation pump 40 controls the flow direction of the oil in the circulation line 20 based on the detection result of the liquid level detection device 50. The filter device 60 is provided on the circulation line 20.
With the technical solution of the present embodiment, when the liquid level detection device 50 detects that the oil level in the oil pan 30 is too low, the circulation pump 40 pumps the oil from the oil tank 10 into the oil pan 30; when the liquid level detection device 50 detects that the oil level in the oil pan 30 is excessively high, the circulation pump 40 pumps excess oil from the oil pan 30 into the oil tank 10, thereby allowing the oil in the oil pan 30 to maintain an optimum liquid level at any time. Further, the filtering device 60 filters the engine oil during the circulation process, thereby slowing the deterioration of the engine oil and prolonging the replacement period of the engine oil. When needing to be changed machine oil, be connected circulating line 20 and outside waste oil bucket and new machine oil bucket, can realize the change of machine oil, simplified machine oil and changed the operation. Therefore, the technical scheme of the embodiment overcomes the defects that the engine oil of the excavator is frequently changed and the operation is complex in the prior art.
It should be noted that the oil tank 10 is an external oil tank, that is, the oil tank 10 is provided independently from the oil pan 30 of the engine, and the oil tank 10 and the oil pan 30 are connected by the above-mentioned circulation line 20.
The above-mentioned "the circulation pump 40 controls the flow direction of the oil in the circulation line 20 based on the detection result of the liquid level detection device 50" means that when the liquid level detection device 50 detects that the oil level in the oil pan 30 is low (lower than the oil lower groove 32), the circulation pump 40 pumps the oil in the oil tank 10 into the oil pan 30, thereby replenishing the oil in the oil pan 30. When the liquid level detection device 50 detects that the oil level in the oil pan 30 is high (above the upper oil scribe line 31), the circulation pump 40 pumps the excess oil in the oil pan 30 into the oil tank 10, thereby reducing the liquid level in the oil pan 30. By the cooperation between the circulation pump 40 and the liquid level detection device 50, the liquid level in the oil pan 30 can be always kept at an optimum height.
As shown in fig. 1, in the solution of the present embodiment, the circulation line 20 includes a first circulation line 21 and a second circulation line 22, and the circulation pump 40 includes a first circulation pump 41 and a second circulation pump 42. Wherein both ends of the first circulation pipeline 21 are respectively communicated with the oil pan 30 and the oil tank 10, the first circulation pump 41 is arranged on the first circulation pipeline 21, and the first circulation pump 41 is adapted to make the engine oil flow from the oil pan 30 to the oil tank 10. Both ends of the second circulation pipe 22 communicate with the oil pan 30 and the oil tank 10, respectively, and a second circulation pump 42 is provided on the second circulation pipe 22, the second circulation pump 42 being adapted to cause the oil to flow in the direction from the oil tank 10 to the oil pan 30.
Specifically, the first circulation pump 41 functions to pump the oil in the oil pan 30 into the oil tank 10, and the second circulation pump 42 functions to pump the oil in the oil tank 10 into the oil pan 30. The circulation control of the oil in the oil pan 30 and the oil tank 10 is made more flexible by providing the circulation pump 40 as a dual pump. When the liquid level detection device 50 detects that the liquid level in the oil pan 30 is excessively low, the first circulation pump 41 is activated, and the second circulation pump 42 is deactivated, thereby pumping the oil in the oil tank 10 into the oil pan 30. When the liquid level detection device 50 detects that the liquid level in the oil pan 30 is excessively high, the second circulation pump 42 is activated, and the first circulation pump 41 is deactivated, thereby pumping the excess oil in the oil pan 30 into the oil tank 10 by the circulation pump 40.
Of course, the first circulation pump 41 and the second circulation pump 42 may be operated simultaneously. That is, while the engine oil in the oil pan 10 is pumped into the oil pan 30, the engine oil in the oil pan 30 is pumped into the oil pan 10 by the circulation pump 40, so that the liquid level in the oil pan 30 is kept in dynamic balance, and the engine oil is filtered through the filtering device 60 continuously. At this time, the oil tank 10 is equivalent to an oil pan externally connected to the engine, and the engine oil in the oil tank 10 becomes a part of the engine oil of the engine, so that the engine oil capacity of the engine lubrication system is increased, the heat dissipation area of the engine oil is increased, and the engine oil filling period is prolonged.
As shown in fig. 1, in the solution of the present embodiment, the connection point of the first circulation pipe 21 and the oil pan 30 is located between the upper and lower limit oil levels of the oil pan 30. Specifically, the connection point of the first circulation pipe 21 to the oil pan 30 is located between the upper oil score line 31 and the lower oil score line 32 of the oil pan 30. Specifically, the above arrangement makes it impossible to pump the oil in the oil pan 30 into the oil tank 10 even if the first circulation pump 41 is operated when the oil level in the oil pan 30 is lowered to a certain height, thereby preventing the oil level in the oil pan 30 from being excessively low.
As shown in fig. 1, in the solution of the present embodiment, the connection point of the second circulation pipe 22 and the oil pan 30 is located above the upper limit oil level. Specifically, the connection point of the second circulation pipe 22 to the oil pan 30 is located above the upper oil division line 31 of the oil pan 30. Specifically, the second circulation line 22 is replenished with oil from above the oil pan 30.
Therefore, in the present embodiment, the connection point of the first circulation pipe 21 and the oil pan 30 is located at the lower portion of the oil pan 30, and the connection point of the second circulation pipe 22 and the oil pan 30 is located at the upper portion of the oil pan 30.
Based on above-mentioned structure, when the machine oil that needs in to machine oil case 10 is changed, be connected the tip of second circulating line 22 with the oil drum of collecting used oil, second circulating pump 42 work will need the machine oil pump that changes to the oil drum in. Then, the end of the first circulation line 21 is connected to an oil drum containing fresh oil, and the first circulation pump 41 operates to pump the fresh oil into the oil tank 10. The first circulation pipe 21 and the second circulation pipe 22 are then returned to the oil pan 30, so that new oil is circulated into the oil pan 30.
As shown in fig. 1, in the solution of the present embodiment, a filtering device 60 is disposed on the second circulation line 22. Specifically, when the second circulation pump 42 operates, the engine oil is filtered by the filter device 60 and then enters the oil pan 30, so that the deterioration time of the engine oil is reduced, and the engine oil replacement cycle is prolonged. The ultra-large excavator can be in a continuous working state after working for a long time by prolonging the mechanism replacement period, so that the downtime is reduced, and the excavator can complete more works. Thereby achieving the effect of saving cost.
Preferably, the filter device 60 is an oil filter.
Preferably, the liquid level detection device 50 is a liquid level sensor. Of course, the liquid level detection device 50 may be other detection mechanisms, such as a float system.

Specifically, the circulation pump 40 is a bidirectional pump. The circulation line 20 includes a first circulation line 21, a second circulation line 22, and a third circulation line 23. Both ends of the first circulation pipe 21 communicate with the first port of the circulation pump 40 and the oil pan 30, respectively. The first end of the second circulation pipeline 22 and the first end of the third circulation pipeline 23 are both communicated with the oil tank 10, the engine oil filling system further comprises a reversing valve 70, and the second end of the second circulation pipeline 22, the second end of the third circulation pipeline 23 and the second port of the circulation pump 40 are connected through the reversing valve 70. The reversing valve 70 is adapted to selectively communicate the second port of the circulation pump 40 with the second end of the second circulation line 22 or the second end of the third circulation line 23.
Specifically, one of the second circulation line 22 and the third circulation line 23 is used for transporting oil from the oil tank 10 into the oil pan 30, and the other is used for transporting oil from the oil pan 30 into the oil tank 10. In the second embodiment, the second circulation line 22 is used for conveying oil from the oil pan 30 into the oil tank 10, and the third circulation line 23 is used for conveying oil from the oil tank 10 into the oil pan 30. As can be seen from fig. 2, the direction change valve 70 is a two-position three-way direction change valve, and when the direction change valve 70 is in the lower position, the circulation pump 40 is communicated with the second circulation line 22, and the pumping direction of the circulation pump 40 is from the oil pan 30 to the oil tank 10. When the direction change valve 70 is in the upper position, the circulation pump 40 communicates with the third circulation line 23, and the pumping direction of the circulation pump 40 is the direction from the oil tank 10 to the oil pan 30.
Further, the first end of the third circulation line 23 is connected to the top of the oil tank 10, thereby preventing bottom precipitated impurities in the oil tank 10 from being injected into the oil pan 30 when the oil pan 30 is filled with oil. Accordingly, a first end of the second circulation line 22 is connected to the bottom of the sump 10. The filter device 60 is provided on the third circulation line 23, and when oil is pumped from the oil tank 10 into the oil pan 30, the oil is filtered by the filter device 60.
Of course, in the second embodiment, the second port of the circulation pump 40, the second end of the second circulation line 22, and the second end of the third circulation line 23 are not limited to the connection by the selector valve 70. For example, after the three are connected, valves are provided in both the second circulation line 22 and the third circulation line 23. When it is desired to pump oil from the oil tank 10 to the oil pan 30, the valve on the third circulation line 23 is opened and the valve on the second circulation line 22 is closed. When it is desired to pump oil from the sump 30 to the sump 10, the valve in the second circulation line 22 is opened and the valve in the third circulation line 23 is closed.
