Abstract
The utility model discloses a machine oil suction filter used for an engine. The machine oil suction filter comprises an oil suction pipe and a filter screen assembly; the oil suction pipe is installed outside an oil pan of the engine; the filter screen assembly is arranged at one end of the oil suction pipe and installed in the oil pan of the engine; an oil suction pipe flange arranged at the end of the oil suction pipe is fixedly connected with the filter screen assembly in a sealed mode through screws and seal rings. The machine oil suction filter used for the engine has the advantages that due to the facts that a filter screen connector, a welded steel tube, a filter tube, a filter screen and an end cover of the filter screen assembly are welded into a whole, and the oil suction pipe is completely arranged outside the oil pan, the number of parts of the machine oil suction filter is reduced, and the machine oil suction filter is quite convenient to demount and mount; only one position of the oil suction pipe needs sealing, the sealed position can be sealed through O-type seal rings, and sealing is simple and reliable in structure; one sealed position is omitted, and standard parts can be selected for sealing, so that cost is low; because the number of the parts is reduced, use reliability is improved, the abrasion degree of a pipe body of the oil suction pipe is reduced, and therefore service life is prolonged.
Description
Technical field
The utility model relates to engine art, especially relates to a kind of engine oil strainer.
Background technique
The effect of engine oil strainer is the impurity in preliminary filter oil drain pan or sump, avoid impurity to enter into the engine lubrication passage, most sump strainers adopt filter structure to be filtered, filter mesh can be stopped up by impurity, and this just needs the impurity in the periodic cleaning net-filter assembly or changes filter screen.The machine oil collection filter device that motor uses at present can be divided three classes according to arrangement: the first kind is that sump strainer and inlet line are arranged in crankcase, multiplex in mini engine, compact structure, but dismounting inconvenience, Equations of The Second Kind is that sump strainer and inlet line are arranged in outside motor, multiplex in large-scale and super-huge motor, its good filtration effect, easy to maintenance, but complicated layout, involve great expense, mostly be independently lubricating oil processing unit, the 3rd class is that sump strainer is arranged in crankcase, inlet line is arranged in outside motor, compact structure is arranged, dismounting is easy to maintenance, the series of advantages such as cheap, big-and-middle-sized diesel engine needs pre-oil supply system more, general the 3rd class arrangement that adopts, such sump strainer comprises fuel sucking pipe and the net-filter assembly be arranged in engine sump, fuel sucking pipe is fixedly mounted on the support of oil sump, the left end of fuel sucking pipe seals and inserts in net-filter assembly by felt, net-filter assembly comprises chimney filter, filter screen, left end cap and right end cap, chimney filter, filter screen, left end cap and the right end cap structure that is welded as a whole, wherein filter screen is welded on chimney filter, the pipe shaft of chimney filter has a plurality of through holes, left end cap and right end cap are arranged in the chimney filter two ends, for supporting chimney filter, wherein right end cap is provided with the endoporus matched with fuel sucking pipe, fuel sucking pipe left end outer ring was inserted this endoporus and was sealed by felt, the chimney filter left end of net-filter assembly is arranged in the male ports of oil sump, be provided with successively from left to right cover plate in male ports, sealing gasket, the felt envelope, cover plate by screw by sealing gasket, (see figure 3) that felt seals and net-filter assembly is tightly connected, there are the following problems for this sump strainer:
