Description
Technical Field
The invention relates to a rack for engine testing, in particular to a method and a device for cleaning an engine oil circulating system of an engine rack.
Background
The frictional work during engine operation is one of the important criteria for evaluating the efficiency of engine operation. The friction work of the engine has a direct influence on the output torque and the fuel consumption of the engine. In recent years, low friction engine technologies have been rapidly developed thanks to the application of many new materials and new technologies. In order to verify the friction reduction effect of the new materials and the new technology, the friction work measurement of the engine needs to meet high precision requirements.
The physical parameters of the engine oil have a very significant influence on the measurement result of the friction work of the engine. Therefore, in an engine bench test which has a high requirement on the measurement accuracy of the frictional work, the test bench is often required to be able to realize a constant temperature function of the oil circulation system, so that the oil supply temperature in the engine is kept constant. The engine bench oil circulating system not only can ensure the circulating flow of the engine oil between the engine and the bench, but also can realize the heat exchange process of the engine oil and the environment, so that the temperature of the engine oil does not exceed the allowable range. Therefore, the piping of the engine mount oil circulation system is generally complicated. In addition, because different engines use different types of oil, the corresponding oil used by the engine needs to be replaced before the bench test on the engine. However, the high viscosity and poor flow characteristics of the oil and the complex plumbing of the engine mount oil circulation system result in often inefficient oil replacement. In addition, the inner wall of the pipeline of the engine pedestal oil circulation system also can remain part of the engine oil and impurities, and the residual engine oil and impurities can change the physical parameters of the newly added engine oil, so that the measurement result of the friction work of the engine is influenced.

The following description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
Fig. 1 schematically illustrates a washing device 1 for an engine mount oil circulation system 10 according to the present disclosure. As can be seen from fig. 1, the washing device 1 comprises a compressed gas supply 2 for supplying compressed gas to flush the engine block oil circulation system 10. The compressed gas supply means 2 here comprises, by way of example, a compressed gas source 21 and a compressed gas filter 22, which is connected to the lower end of the compressed gas source 21. Here, the compressed gas filter 22 is preferably configured to be able to not only remove water, oil, and other impurities in the compressed gas, but also to adjust the pressure of the input compressed gas so that the outflow rate of the oil from the engine mount oil circulation system 10 is within a reasonable range. Meanwhile, the cleaning device 1 further includes an oil supply mechanism 3 for supplying oil to rinse the engine mount oil circulation system 10. Illustratively, the oil supply mechanism 3 includes an oil fill port 31, which is preferably configured in a funnel shape to facilitate oil addition. Furthermore, as can be seen from fig. 1, the compressed gas supply means 2 and the oil supply means 3 are each connected to a purge means 4, and the piping structure of the purge means 4 is exemplarily shown in fig. 3, and as can be seen from fig. 3, the purge means has two inlets and one outlet, wherein the purge means 4 pressurizes the oil by introducing fresh oil through one of the inlets and then introducing filtered compressed gas through the other inlet, so that the pressurized oil flows out from the outlet of the purge means 4. In this example, the outlet of the washing means 4 is connected to an engine stand oil circulation system 10.
Furthermore, as can be seen in fig. 1, a first ball valve 23 is also provided at the output of the compressed gas filter 22, the other end of the first ball valve 23 being connected to the input of the cleaning means 4. Whether the gas is introduced into the cleaning mechanism 4 from the compressed gas filter 22 is controlled by opening and closing the first ball valve 23. Illustratively, in the disclosed cleaning device 1, the first ball valve 23 is configured to be normally closed.
Further, exemplarily, it can also be seen from fig. 1 that a second ball valve 32 is provided in the connecting line of the oil supply mechanism 3 and the purge mechanism 4, which is provided to control the oil inflow speed and the inflow amount by controlling the size of the opening degree of the second ball valve 32.
Furthermore, the washing device 1 may be provided with a quick connection 6, for example, and the output of the washing connection may be conveniently connected to the input of the engine mount oil circulation system 10 through the quick connection 6. It should be explained here that quick connections are often used for hydraulic lines. When the quick connector is used, the quick connector directly inserts a plug connected to a matched pipeline into a joint of the pipeline on the other side.
Furthermore, as can be seen from fig. 1, the washing device 1 may be further provided with an oil storage mechanism 5 connected to an output of the engine mount oil circulation system 10 for storing the oil flowing out of the engine mount oil circulation system 10. Further, a third ball valve 51 that is normally closed may be provided in the connecting line of the oil reservoir mechanism 5 and the engine mount oil circulation system 10. The third ball valve 51 is opened when the engine mount oil circulation system 10 is cleaned, so that the waste oil can be discharged from the engine mount oil circulation system 10.
Based on the above washing device 1 for the engine mount oil circulating system 10 according to the present disclosure, the present invention also relates to a washing method for the engine mount oil circulating system 10. This cleaning method is exemplarily shown in fig. 2. When the engine mount oil circulation system 10 needs to be cleaned, the cleaning mechanism 4 is connected to the engine mount oil circulation system 10 through the quick connection 6. While leaving the first 23, second 32 and third 51 globe valves in a closed state.
Specifically, referring to fig. 2, the cleaning method according to the present disclosure includes the steps of:
The engine rig oil circulation system 10 is flushed with compressed gas. Here, for example, during this time, the first and third ball valves 23, 51 are caused to remain in an open state; the compressed gas source 21 is opened to introduce compressed gas into the engine mount oil circulating system 10, and the pressure of the compressed gas is adjusted by the compressed gas filter 22, so that the speed of the oil attached to the inner wall of the pipeline flowing from the engine mount oil circulating system 10 to the oil storage mechanism 5 is controlled within a reasonable range. Preferably, the compressed gas is continuously supplied until the adhering oil in the engine mount oil circulation system 10 is substantially drained, i.e., no longer flows into the oil reservoir 5;
the lubricant is rinsed with machine oil and compressed gas. Here, for example, the compressed gas source 21 is closed, and the second ball valve 32 is opened, so that an appropriate amount of oil for rinsing is passed from the oil supply mechanism 3 into the engine mount oil circulation system 10; after the introduced engine oil completely flows into the cleaning mechanism 4 and the engine oil circulating system, closing the second ball valve 32; the compressed gas source 21 is opened to introduce compressed gas into the engine oil circulating system, and the pressure of the gas is adjusted through the compressed gas filter 22, so that the previously introduced engine oil is controlled to slowly flow out of the engine pedestal engine oil circulating system 10 to the oil storage mechanism 5, and the engine oil circulating system is lubricated.
Preferably, the above rinsing step using the engine oil and the compressed gas may be repeated several times to achieve a good cleaning effect.
The above examples mainly illustrate the washing method and washing device for the engine mount oil circulation system of the present disclosure. Although only a few embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof. Accordingly, the present examples and embodiments are to be considered as illustrative and not restrictive, and various modifications and substitutions may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
