The universal interface is characterized by consisting of an interface body [1] and a double-thread joint [2], wherein the interface body [1] is a rectangular hexahedron; a circular groove [3] is formed in the center of the lower surface of the interface body [1]; an oil outlet hole [4], an oil outlet pressure hole [5], an oil inlet hole [6] and an oil inlet pressure hole [7] are formed in the interface body [1]; the upper thread pipe orifice of the double-thread joint [2] is screwed in the internal thread of the lower end of the oil outlet hole [4]; and the lower thread pipe orifice is connected with the internal thread of an oil outlet of the tested filter [8]. The universal interface simplifies the connecting structure of the tested filter and a test device, shortens the operation time, improves the working efficiency and reduces the test cost.
Description
Technical field
The invention belongs to and belong to filtrator detection technique field, relate to a kind of general-purpose interface that is used for the test of spin-on filter filtration efficiency.
Technical background
At present, when spin-on filter is carried out the filtration efficiency test, test unit need be connected by complicated pipelines with underproof filtrator, the oil-out of test unit is connected with the oil-in of underproof filtrator by in-line, the oil-out of underproof filtrator is connected with the oil return opening of test unit by return line, and in-line also will be connected with oil return pressure measurement pipeline with oil-feed pressure measurement pipeline respectively with return line.Because underproof filter specification difference, above-mentioned connecting line also will use X-over to carry out the joint conversion according to underproof filter specification.Its shortcoming is: the syndeton complexity, prolonged the running time, and reduced work efficiency, increased experimentation cost.
Summary of the invention
The objective of the invention is: provide that a kind of syndeton is simple, simple operation, high efficiency, the low general-purpose interface that is used for the test of spin-on filter filtration efficiency of experimentation cost.
Summary of the invention
Technical scheme of the present invention is: be used for the general-purpose interface of filtrator filtration efficiency test, it is characterized in that it is made up of interface body and double thread joint; Interface body is a rectangular hexahedron, a circular groove is arranged at the center of interface body lower surface, the diameter of circular groove is less than the external diameter of being tested the filter body upper port, and the length of side of interface body lower surface is greater than the external diameter of being tested the filter body upper port; An oil outlet is arranged in interface body inside, the lower port of oil outlet is positioned at the center of circular groove bottom land, the upper port of oil outlet is positioned on the right flank of interface body, the upper and lower port of oil outlet all has internal thread, also have a fuel-displaced pressure tap that connects with oil outlet on the right flank of interface body, the port that fuel-displaced pressure tap is positioned at the interface body right flank has internal thread; An oil supply hole is arranged in interface body inside, the lower port of oil supply hole is positioned at the bottom land of circular groove, the position of close cell wall, the upper port of oil supply hole is positioned on the left surface of interface body, the upper port of oil supply hole has internal thread, also have an oil-feed pressure tap that connects with oil supply hole on the left surface of interface body, the port that the oil-feed pressure tap is positioned at the interface body left surface has internal thread; Outer six sides in the middle of the threaded end (TE) connect to form the double thread joint by last threaded end (TE), following threaded end (TE) with about being positioned at; Last threaded end (TE) is screwed in the internal thread of oil outlet lower port, and following threaded end (TE) is connected with the internal thread of being tested the filtrator oil-out.
Advantage of the present invention is: simplified the syndeton of underproof filtrator and test unit, shortened the running time, improved work efficiency, reduced experimentation cost.Evidence, behind employing the present invention, work efficiency is more than doubled.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below the present invention is described in further details.Referring to Fig. 1, be used for the general-purpose interface of filtrator filtration efficiency test, it is characterized in that it is made up of interface body 1 and double thread joint 2; Interface body 1 is a rectangular hexahedron, at the center of interface body 1 lower surface a circular groove 3 is arranged, the diameter of circular groove 3 is less than the external diameter of being tested the filter body upper port, and the length of side of interface body 1 lower surface is greater than the external diameter of being tested the filter body upper port; In interface body 1 inside an oil outlet 4 is arranged, the lower port of oil outlet 4 is positioned at the center of circular groove 3 bottom lands, the upper port of oil outlet 4 is positioned on the right flank of interface body 1, the upper and lower port of oil outlet 4 all has internal thread, also have a fuel-displaced pressure tap 5 that connects with oil outlet 4 on the right flank of interface body 1, the port that fuel-displaced pressure tap 5 is positioned at interface body 1 right flank has internal thread; In interface body 1 inside an oil supply hole 6 is arranged, the lower port of oil supply hole 6 is positioned at the bottom land of circular groove 3, the position of close cell wall, the upper port of oil supply hole 6 is positioned on the left surface of interface body 1, the upper port of oil supply hole 6 has internal thread, also have an oil-feed pressure tap 7 that connects with oil supply hole 6 on the left surface of interface body 1, the port that oil-feed pressure tap 7 is positioned at interface body 1 left surface has internal thread; Outer six sides in the middle of the threaded end (TE) connect to form double thread joint 2 by last threaded end (TE), following threaded end (TE) with about being positioned at; Last threaded end (TE) is screwed in the internal thread of oil outlet 4 lower port, and following threaded end (TE) is connected with the internal thread of being tested filtrator 8 oil-outs.
Using method of the present invention is: at first, the oil supply hole 6 of interface body 1 is connected with the flowline of test unit, the oil outlet 4 of interface body 1 is connected with the scavenge pipe of test unit, threaded end (TE) on the double thread joint 2 is screwed in the internal thread of oil outlet 4 lower port, and following threaded end (TE) is connected with the internal thread of being tested filtrator 8 oil-outs.The high-pressure side of differential pressure indicator is connected with fuel-displaced pressure tap 5 with oil-feed pressure tap 7 respectively with low pressure end.After all pipelines connected, the starting characteristics test device can carry out the test of filtrator filtration efficiency.Double thread joint 2 is according to being manufactured series of products by the specification of test filtrator, and the filtrator of being tested with different size is used respectively.When the filtrator of test different size, do not need to dismantle the flowline and the scavenge pipe of test unit, as long as change with by the supporting double thread joint of test filtrator, can be coupled together by test filtrator and interface body and test.
