Abstract
The utility model relates to a lubricating oil automatic backwashing combined strainer of a large engine and resolves the problem of relatively large size of a lubricating oil strainer of the large engine. The technical scheme is that the lubricating oil automatic backwashing combined strainer is provided with two backwashing strainers are installed in parallel to a bypass strainer; two oil inlet flange openings of the two backwashing strainers and an oil inlet of the bypass strainer are connected in parallel via an oil inlet pipeline; and two oil outlet flange openings of the two backwashing strainers and an oil outlet of the bypass strainer are connected in parallel via an oil outlet pipeline. Large volume lubricating oil is divided by several strainers to be strained and by an inner strainer element and an outer strainer element inside the bypass strainer to be strained so as to overcome shortcomings of manufacturing, maintenance and cost caused by using relatively large lubricating oil straining devices. Additionally, the novel design of adopting the outer strainer element to be sleeved into the inner strainer element of the bypass strainer is capable of guaranteeing sufficient straining area matched with the lubricating oil automatic backwashing strainer, reducing outline space by a half and lowering cost due to the fact that the bypass strainer has only one body.
