Abstract
The utility model relates to a single stage oil bath type air filter for a single-cylinder engine. The single stage oil bath type air filter for a single-cylinder engine is composed of an upper cover, a filter core element, an oil pool, an air outlet pipe, etc. Because an oil baffle ring is arranged in the oil pool, oil flow in the oil pool is guided and oil mass splashed on a filter net can be controlled. The filter efficiency of the air filter and the service life of a lab are enhanced. In addition, the height of an oil surface in the oil pool is enhanced. The seal reliability of the seal components is improved. An important role is played for enhancing the performance of the air filter. The air filter of the utility model has the favorable performances of low resistance, small oil losing rate, high efficiency of filtering, long service life of the lab, etc. The problem of critical premature wear of a present single-cylinder diesel is relieved.
Description
The utility model relates to the combustion-air cleaner that is loaded on the internal-combustion engine, particularly a kind of air-strainer that air is worked through oil bath.
Chinese patent 93225936.7 " air-strainer that small diesel engine is used " discloses a kind of oil bath air cleaner that can make an amount of band oil suction dish that goes to the filter gauze of oil in the oil sump on the ground.Show that through experimental study afterwards existing filter cleaner exists oily stream does not have good guiding, fluid can not be splashed to oil mass online or that be splashed on the filter screen with air stream can not get control; And low on fuel two big shortcomings in the oil sump, cause filter cleaner filtering efficient not high, cause the serious premature wear of diesel engine parts.93225936.7 though patent has solved oily conductance to problem, exist the manufacturing of the sealing problem that increases oil sump after the oil mass and sucker and trouble is installed, still can further improved problem.
The purpose of this utility model a: part is set in the single-stage oil bath air cleaner, oily stream is led, and control is splashed to the oil mass on the filter screen, improves fuel head and improves the sealing at sealing position, to realize improving filtering efficiency, test room's life-span and operational safety.
The purpose of this utility model is by a upright shelves scraper ring is set in oil sump, and is aided with oil sump, steam outlet pipe and filter core center tube structure size, and mutual Placement and sealing means do necessary improvement, and fuel head realizes to improve.
Accompanying drawing 1 is the structural drawing of the utility model air-strainer.Fig. 2 and Fig. 3 are respectively two embodiments' structural drawing in addition, and 1 is nut among the figure, and 2 is packing ring, and 3 is loam cake, and 4 is the loam cake seal ring, 5 is filter element part, and 6 is oil sump, and 7 is seal ring, and 8 is the shelves scraper rings, 9 is steam outlet pipe, and 10 is flange, and 11 is the filter core center tube, and 12 is the trough of belt seal ring.
Provide embodiment of the present utility model in conjunction with the accompanying drawings.
The utility model basic structure is similar with existing air-strainer, and it is made up of loam cake 3, filter core 5, oil sump 6, steam outlet pipe 9, and loam cake 3 and steam outlet pipe 9 fuse by stay-bolt, nut 1, packing ring 2.Filter core 5 and oil sump 6 are fixed on loam cake and the steam outlet pipe 9 with flange, seal ring 4 is used for sealing the space between loam cake 3 and the filter core 5, seal ring 7 is installed in and reaches between oil sump and the filter core 6 between steam outlet pipe 9 and the oil sump 6, be used for sealing oil liquid leakage in the oil sump and the air in the air flue and enter oil sump, flange 10 is enclosed within on the steam outlet pipe 9, in order to filter cleaner to be installed.Filter core 5 is made up of last platen, center tube 11, filter screen and peripheral filter core box.Characteristics of the present utility model are to set up a shelves scraper ring 8 in oil sump 6, it is a thin walled cylinder that thin plate is rolled into, also can be cylindrical, taper shape or turbination, surface after tested, the size suitable for reading of shelves the scraper ring 8 and highly performance of filter cleaner is had very big influence, grade scraper ring position suitable for reading, diameter just suitable for reading determines according to the bottom annulus area of filter core, is the best with heart position therein.The height of shelves scraper ring, just the shelves scraper ring distance between filter core suitable for reading being according to being directly proportional with air mass flow, calculates with the filter core external diameter and at the formula of the rapid-result inverse ratio of air radial flow of outer radius.Shelves scraper ring 8 is connected and fixed with the bottom spot welding of oil sump 6.For improving fuel head, the center tube 11 in oil sump 6, steam outlet pipe 9 and the filter core 5 is made new design, there are three kinds of schemes available.
Embodiment 1.As shown in Figure 1, shelves scraper ring 8 is connected with oil sump 6 bottom spot welding, is used for oily stream in the oil sump is led, oil mass on the control filter screen is increased the flange of location, oil sump 6 middle parts seal ring, and is suitable for reading higher more than 10 millimeters than shelves scraper ring 8, with 10～15 millimeters is good, is used for improving fuel head.
Implement 2.As shown in Figure 2, in oil sump, establish ring washer, and filter core center tube 11 is shortened,, oil sump and steam outlet pipe are press-fitted the back spot welding are integral the steam outlet pipe lengthening with embodiment 1, and the sealing on reinforcement mating face, be used for improving fuel head.
Implement 3.As shown in Figure 3, in oil sump, establish a grade scraper ring, and filter tube 11 is shortened,, make it be higher than a grade scraper ring height steam outlet pipe and oil sump middle part pipe lengthening with embodiment 1, and with steam outlet pipe flange suitable for reading.Seal with the junction point of trough of belt seal ring 12, be used for improving fuel head filter core, oil sump, steam outlet pipe.
To in the present mass-produced 195A type single-stage oil bath air cleaner a grade scraper ring being set, shelves scraper ring back cut diameter is 90～95 millimeters, and the distance to the filter core bottom suitable for reading is 8～12 millimeters.In oil sump, refuel, make pasta suitable for reading equal with the shelves scraper ring, the about 345g of volume read-out this moment, by the international standard test method, through test, its filtering efficiency reaches more than 99.5%, and storage ash amount reaches 400g, various performances all reach and surpass JB WQ67, the grade quality index of the Grade A (existing quality award from the province, quality award from the ministry) stipulated in the quality index standard of 1-87 combustion air cleaner assembly quality of product.
Use the utility model air-strainer, the premature wear problem of present various lots of single cylinder diesel is alleviated greatly.
The utility model is applicable on the various single cylinder diesels of cylinder diameter 65mm to 110mm.Also can be used on the single cylinder petrol engine.
