Novel diesel oil filter with exhaust function

Abstract

The invention provides a novel diesel oil filter with an exhaust function. The novel diesel filter includes a shell, a thread cover board assembly, a filter element, an inner sealing ring, an exhaust device and diversion pipes, wherein the upper end of the shell is provided with the thread cover board assembly; the filter element is arranged inside the shell; the inner sealing ring is arranged between the filter element and the thread cover board assembly; the exhaust device used for exhausting accumulating air in the filter is arranged on the inner sealing ring; the diversion pipes used for guiding diesel oil are arranged in the filter element and the diversion pipes extend from the upper end of the filter element to the lower end of the filter element so that when a motor starts, the diesel oil can be pumped quickly. According to the novel diesel oil filter with the exhaust function, the problem of air accumulation inside a tank of the filter is resolved and the filter paper use ratio is improved. Meanwhile, when a common-rail engine starts, sufficient diesel oil supplies in the filter are guaranteed and normal starting of the engine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of separation and filtration, and more particularly relates to a novel diesel filter with an exhaust function. Background technique [0002] The diesel filter is an important part of the diesel engine system, and its main function is to filter the diesel fuel supplied to the engine. Due to replacement of the filter element and precipitation of diesel-soluble air in the low-pressure pipeline, a large amount of gas will accumulate in the filter. When the engine is running, these gases cannot penetrate the filter paper and can only accumulate on the front side of the filter. As a result, the liquid level on the front side of the filter decreases, and the utilization rate of the filter paper decreases; and after the engine stops running, due to the pressure difference between the front side and the rear side of the filter, the accumulated air will slowly penetrate the filter paper, making the rear side of the fi...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned deficiencies in the prior art that gas accumulates in the filter, resulting in low effective utilization of filter paper and difficulty in starting the engine, the present invention provides a new type of diesel filter with exhaust function to solve the problem of gas in the filter tank. In order to improve the utilization rate of the filter paper; at the same time, when the common rail engine is ignited and started, ensure that there is enough diesel in the filter to make the engine start normally
