Installing structure for diesel engine oil filter

Abstract

The invention relates to an installing structure for a diesel engine oil filter. Specifically, the engine oil filter is installed in a machine body side cover; the side cover is provided with an engine oil cavity; the engine oil filter is inserted into the engine oil cavity, and comprises a hollow filtering segment and a sealing cover cap arranged on the head portion of the filtering segment; the sealing cover cap and the opening portion of the engine oil cavity are in threaded connection and are sealed through a first sealing ring; the outer wall of the tail portion of the filtering segment and the inner wall of the circumference of the engine oil cavity are in sealing contact and are sealed through a second sealing ring; the engine oil cavity comprises an oil inflow cavity defined by the inner wall of the engine oil filter and an oil outflow cavity defined by the outer wall of the engine oil filter and the inner wall of the side cover; the side cover is provided with an oil inlet corresponding to the oil inflow cavity and an oil outlet corresponding to the oil outflow cavity; and engine oil flowing in from the oil inlet is filtered by the engine oil filter after directly entering the oil inflow cavity, and permeates into the oil outflow cavity to flow out of the oil outlet. By means of the installing structure for the diesel engine oil filter, the filtered engine oil can be completely isolated from non-filtered engine oil, and the filtering effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of diesel engine accessories, in particular to an installation structure of a diesel engine oil filter. Background technique [0002] The oil filter is one of the important parts of the diesel engine. It is used to filter impurities such as dust, metal particles, carbon deposits and bituminous coal particles in the oil, and can play a good role in protecting the lubrication of the diesel engine. [0003] See figure 1 At present, the existing oil filter 2 on the market uses the curved surface near its own oil outlet to contact the oil chamber 3 of the side cover 1 to achieve the purpose of partitioning, but this kind of sealing effect is not good, and the oil filter 2 There is a gap between the curved surface near the oil outlet and the oil chamber 3 of the side cover 1, causing some unfiltered dirty oil to seep in, resulting in incomplete oil filtration. Simultaneously, because of the particularity of the ...

Problems solved by technology

[0003] See figure 1 At present, the existing oil filter 2 on the market uses the curved surface near its own oil outlet to contact the oil chamber 3 of the side cover 1 to achieve the purpose of partitioning, but this kind of sealing effect is not good, and the oil filter 2 There is a gap between the curved surface near the oil outlet and the oil chamber 3 of the side cover 1, causing some unfiltered dirty oil to seep in, resulting in incomplete oil filtration

At the same time, due to the special structure of the existing oil filter 2, the oil inlet route is relatively complicated, and the oil flow is not very smooth

In addition, in diesel engines produced by different manufacturers, the position of the oil outlet on the side cover will deviate. The problem of inaccurate alignment of the oil port, resulting in poor filtering effect, oil leakage, etc.

[0004] The process that the existing diesel engine oil filter filters machine oil is: figure 1 The direction of the middle arrow indicates the oil flow direction. The oil flowing in from the oil inlet 4 will first be diverted by the oil filter 2, and then the diverted oil will be filtered by the oil filter 2. 5, but because there is a gap between the curved surface near the oil outlet of the oil filter 2 and the oil chamber 3 of the side cover 1, some unfiltered dirty oil seeps into the oil outlet 5, which is the same as the filtered oil The engine oil is discharged together, resulting in incomplete oil filtration, which has a great impact on the use of diesel engines
