Abstract
The utility model relates to an engine oil filter which comprises a shell. A filter element, a bypass valve and a magnetic body are arranged in the shell. The filter element is composed of an oil inlet filter element and an oil outlet filter element. The engine oil filter further comprises a connection pipe. One end of the connection pipe is connected with the outlet end of the oil inlet filter element. The other end of the connection pipe is connected with the inlet end of the oil outlet filter element. The two ends of the connection pipe are connected with cleaning pipes respectively. Through holes are formed in a wall face of the shell. An end portion of each cleaning pipe penetrates through one through hole and is exposed out of the shell and the port, exposed out of the shell, of each cleaning pipe is provided with a sealing plug. The bypass valve is located in the connection pipe and the magnetic body is fixed to the outside of the connection pipe and located in the middle of the connection pipe. The engine oil filter is connected with an external water pressure or air pressure cleaning device to clean adsorbed metal impurities.
Description
Technical field
The utility model relates to a kind of oil filter.
Background technique
Oil filter is for filtering the impurity of machine oil, as everyone knows, the impurity in machine oil can cause very quick-wearing or block of precision pair in Injection Pump and oil sprayer, and the wearing and tearing of precision pair, can cause that each oil supply cylinder is inhomogeneous, oil consumption increases and power declines.Current existing oil filter, adopt multiple filtration net to filter, multiple filtration net carries out multi-level filtration to machine oil the impurity in machine oil is filtered outside filter screen, but when the pressure difference into and out of hydraulic fluid port does not reach certain value, bypass valve in filter cleaner can be opened automatically, machine oil just directly flows into main oil gallery through bypass valve without filtration, thereby the machine oil of filtered will cause the wearing and tearing of precision pair, and some above-mentioned problems, thereby existing oil filter also needs further improvement, raising filtering effect.
For addressing the above problem, in technology, a kind of oil filter is disclosed now, it includes housing, is provided with filter core and bypass valve in described housing, is also provided with magnet in described housing, and magnet is arranged on the below of bypass valve.This oil filter is adsorbed on metal impurities in housing, has avoided metal impurities to enter into the wearing and tearing that in engine block, body caused.But the prolongation along with service time, the metal impurities that are adsorbed in housing can get more and more, thereby the passage between lubricant oil turnover is formed and stopped up, because housing seals, be not easy to clean, thereby cause filter cleaner progressively to reduce the supply of lubricant oil, be unfavorable for the lubricated of engine block.
Model utility content
For above-mentioned technical problem, main purpose of the present utility model is to provide a kind of oil filter, and the utility model can connect external water pressure or air pressure cleaning device, and adsorbed metal impurities are cleared up.
The technological scheme solving the problems of the technologies described above is as follows:
Oil filter, comprise housing, in housing, be provided with filter core, bypass valve and magnet, described filter core is comprised of oil inlet filter element and fuel-displaced filter core, also comprise a connecting tube, one end of this connecting tube is connected with the outlet end of oil inlet filter element, the other end of connecting tube is connected with the entrance point of fuel-displaced filter core, the two ends of connecting tube are connected with respectively scavenge pipe, the wall of described housing is provided with through hole, the end of scavenge pipe is exposed to outside through described through hole, scavenge pipe is exposed in the port of outside and is provided with sealing plug, described bypass valve is arranged in connecting tube, magnet is fixed on the outside of connection, magnet is positioned at the middle part of connecting tube.
Between the outer wall of described scavenge pipe and housing, be provided with seal ring, scavenge pipe frame is welded and fixed.
Adopted such scheme, when magnet is adsorbed on metal impurities after the internal surface of connecting tube, use after a period of time, sealing plug can be taken off, to the mouth of pipe by scavenge pipe, be connected with high pressure water gun, the rinse water to connecting tube to input high pressure, metal impurities are flushed away under the pressure of high hydraulic pressure, or in connecting tube, pass into pressurized gas, metal impurities are flushed away under the pressure of pressurized gas.This manner of cleaning up is not only simple, and convenient.After metal impurities are cleared up, avoided metal impurities accumulation and the obstruction that causes.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1 is housing, and 2 is bypass valve, and 3 is magnet, and 4 is oil inlet filter element, and 5 is fuel-displaced filter core, and 6 is connecting tube, and 7 is scavenge pipe, and 8 is sealing plug.
