Abstract
The invention relates to a lubricant oil automatic backwashing combined filter of a large-scale engine, which solves the problem of larger volume of the lubricant oil filter of the large-scale engine. The invention adopts the technical scheme that two backwashing filters and a bypass filter are installed in parallel; oil inlet flange openings of two backwashing filters are connected with oil inlets of the bypass filter in parallel through an oil inlet pipeline; and oil outlet flange openings of two backwashing filters are connected with oil outlets of the bypass filter in parallel through an oil outlet pipeline. In the invention, large-flow lubricant is filtered by a plurality of filters and by inner and outer filter elements in the bypass filter, thereby avoiding disadvantages in production, maintenance and cost caused by using larger lubricant oil filters. The bypass filter adopts a novel design of combining outer filter element and inner filter element, thereby ensuring enough filtration area to match with the lubricant oil automatic backwashing filter; besides, the body is reduced to one, thereby reducing half appearance space and reducing the cost.

Two backwash filters and by-pass filter are fixed on the support 31 side by side; Two backwash filters are gone into oily flange port 7 and by-pass filter oil-in 20 by inflow pipeline 29 parallel connections; Two fuel-displaced flange ports 8 of backwash filter and by-pass filter oil-out 21 are by flowline 30 parallel connections;
Referring to Fig. 1 and Fig. 2, be separately installed with three-way switch valve mechanism on the inflow pipeline 29 of by-pass filter one side and the flowline 30; Referring to Fig. 6 and Fig. 7, three-way switch valve mechanism comprises T type tee ball valve 22, worm gear 23 is installed on the overhanging end of its valve rod, the worm screw 24 that cooperates with worm gear 23 is installed on the seat board 26 by bearing block 25, seat board 26 is installed on the outside valve body of T type tee ball valve 22, and the end of worm screw 24 is equipped with handwheel 27.
Operation principle of the present invention is as follows:
Under the normal operation, by-pass filter and external system disconnect, and two lubricating oil automatic backwash filters are communicated with external system.Lubricating oil to be filtered is entered the inflow pipeline 29 of bottom by the oil-inlet end three-way switch valve mechanism of bottom, divide and be clipped to the oily flange port 7 of going into of two lubricating oil automatic backwash filters, the filter screen outside of arriving at element kit 2 enters its inboard then, flow to the oil pocket that of body 1 again, to fuel-displaced flange port 8, to the flowline 30 on top, the oil outlet end three-way switch valve mechanism that converges to top sends, thereby lubricating oil is filtered.
In each lubricating oil automatic backwash filter, during along with filtration, accumulating of screen surface dirt, element kit 2 inside and outside differential pressures increase gradually, when increasing to setting value, pressure difference switch by control cabinet 28 sends signal, two magnetic valves of air piping arrangement 6 are opened simultaneously, compressed air begins to drive the cylinder that the backwash arm drives assembly 4, and allow the pneumatic ball valve of recoil washing oil discharge portion part 5 open, then the filter screen pressure of element kit 2 by high outside and low outside become outer low and inner high, so can carry out backwash and discharge sump oil by scraper component 3 by its sewage draining exit, meanwhile, element kit 2 is constantly to rotate under to the driving of its mandrel at cylinder, make each position of filter screen can both arrive scraper component 3 and clean up, the filter screen inside and outside differential pressure has fallen again like this, and two closed electromagnetic valves drive gas circuit.So work automatically circularly.And, two lubricating oil automatic backwash filters be in the same way, same beat work.
Therefore, when two lubricating oil automatic backwash filters carry out backsurging operation, do not interrupt the external system fuel feeding, and because the flow loss of blowdown is relatively very little, system pressure drop is controlled, therefore, and the lubricating oil that can provide cleaning to external system with the pressure and the flow of equal perseverance.
When two lubricating oil automatic backwash filters need be safeguarded, can handle the operation handwheel 27 of three-way switch valve mechanism, spool is rotated to an angle, allow two lubricating oil automatic backwash filters and external system disconnect, then by-pass filter is activated, lubricating oil is entered the oil-in 20 of by-pass filter body 11 by the three-way switch valve mechanism on the inflow pipeline 29, part lubricating oil enters inboard the filtration by outer filter core 13 outsides, go out oil pocket on the arrival by-pass filter body 11, another part arrives inner filter core 12 inboards by the through hole on the filter cartridge seat 18 and enters the outside and filter, also arrive by-pass filter body 11 on go out oil pocket.The unified three-way switch valve mechanism that is entered on the flowline 30 by oil-out 21 sent after two strands of lubricating oil confluxed.
