It obtains its sustainable oil liquid that extracts into fuel tank to be purified, then purified oil liquid is conveyed into oil return box, and pass through installation
Oil water separation filtering has effectively filtered the free water in oil liquid, and has abolished oil-water emulsion structure.
It is further connected with an oil liquid pipeline on oil liquid pipeline between the pressure gauge and filter, is installed on the oil liquid pipeline
There is overflow valve, so that the pipeline that can be connected by overflow valve oil outlet when pressure is more than setting value on oil liquid pipeline returns to oil
Case.
Further, oil suction filtering is also equipped on the oil liquid pipeline between pressure vacuum gauge and gear pump motor group
Device, so that oil liquid is further purified.
Further, it is also equipped with counterbalance valve on the pipeline of the oil water separation filtering to fuel tank, so that oil liquid
Pressure in pipeline can be constant.
Further, it is also equipped with oil liquid detection instrument in the oil liquid Near Pipelines of installation counterbalance valve, so that can be by this
Oil liquid detection instrument detects oil liquid soiled condition, while maintenance personnel can be directed to the dirty journey of oil liquid according to the monitoring result
Degree is pre-processed.
The utility model has the beneficial effects that the utility model has effectively filtered solid particle, free water in oil liquid, together
When abolished oil-water emulsion structure, and on oil liquid pipeline install oil liquid detection instrument so that shield machine oil liquid can be detected constantly
Quality, while maintenance personnel can pre-process according to the monitoring result for the degree of fouling of oil liquid, effectively keep away
Shield machine is shut down caused by having exempted from because of oil liquid problem.

Specific embodiment
The utility model is described further with reference to the accompanying drawings of the specification.
It illustrates, shield machine oil liquid in-line purification system, wraps referring to first embodiment of the attached drawing 1 to the utility model
The oil liquid pipeline that both ends are connect with fuel tank 1 is included, is sequentially installed with pressure vacuum gauge on the oil liquid pipeline along its oil liquid flow direction
2, gear pump motor group 3, pressure gauge 4, filter 5, oil water separation filtering 6.So that its sustainable extraction oil into fuel tank 1
Liquid filters out the solid particulate matter in oil liquid, and filtered oil liquid has effectively filtered in oil liquid using free water knockout 6
Free water, and abolished oil-water emulsion structure, eventually passed back to fuel tank 1.
It is specifically described referring to second embodiment of the attached drawing 2 to the utility model, the installation base based on first embodiment
On plinth, it is further connected with an oil liquid pipeline on the oil liquid pipeline between the pressure gauge 4 and filter 5, pacifies on the oil liquid pipeline
Equipped with overflow valve 7, oil can be returned to by the pipeline that 7 oil outlet of overflow valve connects when pressure is more than setting value on oil liquid pipeline
Case, so that it can filter solid particulate matter in oil liquid and free water and protect entire oil liquid pipeline by overflow valve 7,
Avoid the pressure in oil liquid pipeline excessive.
It is specifically described referring to 3rd embodiment of the attached drawing 3 to the utility model, the installation base based on second embodiment
On plinth, it is also equipped with oil absorption filter 8 on the oil liquid pipeline between the pressure vacuum gauge 2 and gear pump motor group 3, so that
