Specifically, the standard flow value is preset, when the real-time flow value exceeds the preset standard flow value, if the flow of the oil path is abnormal, a flow abnormal indication is generated and sent to the display circuit 500, and if the flow is normal, a flow normal indication is generated and sent to the display circuit 500.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
