Technical Field
[0001] This utility model relates to the field of oil return pipe technology, and in particular to the oil return pipe of the front tank of the oil pan. Background Technology
[0002] The oil pan return line is a pipe in diesel engines or low-speed marine diesel engines used to return lubricating oil from moving parts to the oil pan. Its core function is to transport lubricating oil from the internal components of the diesel engine back to the oil pan, achieving circulating lubrication.
[0003] However, most existing return oil pipes are directly installed on the oil pan during use, which does not provide ideal auxiliary support for the return oil pipe. This can lead to the return oil pipe becoming loose after prolonged use, causing oil leakage at the connection between the return oil pipe and the oil pan, thus affecting its use. Therefore, it is necessary to provide a return oil pipe for the front of the oil pan to solve the above problems. Utility Model Content
