Background technology
Because the processing and manufacturing process of each component in the bulldozer steering brake hydraulic system is more loaded down with trivial details, the solid particulate matter that produces after the processing is difficult for clearing up away, the structure of the oil storage casing of this hydraulic system especially---rear axle box is more complicated again, in scale removal process, there are some dead angles, thereby cause inevitably existing in the manufacturing process impurity such as some solid particulate matters, finally affected complete machine hydraulic pressure cleannes.These solid particulate matters include welding slag weldering beans, ball blast, oxide skin, iron filings etc., blending is in whole hydraulic system, and the relevant Hydraulic Elements such as the hydraulic valve in the system, steering pump are very high to the cleannes requirement of fluid, when containing a certain amount of solid particulate matter in the fluid, will be blended in the course of the work in the gap of spool and valve body, in the intermeshing process of gear, cause the card valve system without turning to, hydraulic pump is stung the faults such as tooth, oil leak, accelerated wear test, thereby strengthens the overall mass that cost of production affects bulldozer.
The utility model content
Technical problem to be solved in the utility model is: a kind of bulldozer special filtering machine is provided, realized the complete machine dynamic filtration of bulldozer, adopt succinctly easily mounting means, satisfy bulldozer draining flow and equal to refuel the condition of flow, make bulldozer move hydraulic system in the original place, thereby comprehensively steering hydraulic oil is fully filtered; Filtration time is short, can adapt to the high productive temp of output; Adopt the series connection of four strainers and compose in parallel, be divided into and be two-stage filter, the ability of filtering and impurity removing is strong; Operation is very simple, safety, reliable, and novel structure, volume are little, simple to operate flexibly, each strainer is provided with pressure protect, carry out pressure monitoring, and be safe and reliable.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of bulldozer special filtering machine, comprise oil-in 1, fuel inlet ball check valve 2, oil pump 3, filter mounting 4, grade one filter 5, pressure meter 6, motor 7, ball valve 8, fuel-displaced ball valve 9, oil-out 10, temperature detection table 11, pressure alarm 12, appliance controling plate 13 and secondary filter 14, oil-in 1 is connected with oil pump 3 by fuel inlet ball check valve 2, and oil pump 3 is connected with grade one filter 5 tops by pipeline, and grade one filter 5 bottoms are connected with secondary filter 14 tops by pipeline, grade one filter 5 and secondary filter 14 fix by filter mounting 4, grade one filter 5 and secondary filter 14 tops are equipped with pressure meter 6, temperature detection table 11 and pressure alarm 12, and motor 7 is connected with oil pump 3, ball valve 8 is connected with oil-out 10 by fuel-displaced ball valve 9, is provided with appliance controling plate 13 between grade one filter 5 and the secondary filter 14.
Described grade one filter 5 is two grade one filters, and longitudinal arrangement is in secondary filter 14 opposites.
Described secondary filter 14 is two secondary filters, and longitudinal arrangement is in grade one filter 5 opposites.
Operating principle of the present utility model: this filter has configured the special joint of special connection bulldozer rear axle box fuel outlet, connect complete rear when filter is worked, fluid in the rear axle box enters into grade one filter and filters after sucking oil pump by oil-in through fuel inlet ball check valve under the swabbing action of oil pump, this moment, large granular impurity was just by filtering, then fluid enters secondary filter by pipeline, the less solid particle of filtering diameter of the degree of depth again, through two cover thickness strainers in parallel, can significantly improve the cleannes of hydraulic system.Fluid after the cleaning is controlled flow direction by ball valve, through fuel-displaced ball valve, directly entered from the rear axle box oil-in by conveyance conduit by oil-out, the operator is then by finally reaching the dynamic filtration of rear axle box inner fluid to the original place hydraulic system operation of bulldozer again.
The beneficial effects of the utility model are: simple in structure, convenient operation, safe and reliable, filtration time is short, the filtering and impurity removing ability is strong, can remove significantly the solid particulate matter in the bulldozer steering brake hydraulic system, significantly improve the quality of fluid, reduce the cleannes grade of fluid, after bulldozer fluid is clean, can avoid because the hydraulic valve card valve that oil contamination causes, the oil sealing wear and aging, the too high components and parts that cause of system temperature damage too early, increase the application life of element, improve the quality level of complete machine.
