Abstract
The utility model relates to a maintenance indicator for an air filter, which makes use of the vacuum principle and adopts vertical straight reading to improve accuracy and precision with the advantages of extending the service life of a filter, reducing oil consumption, and convenient operation. The utility model is composed of a dustproof cover 1, a locking resetting button 2, an upper cover 3, a corrugated sealing ring 4, a sleeve tube 5, a slide scale 6, a spring 7 and an outer shell 8. After a machine is started, the sealing action of the corrugated sealing ring 4 and the upper cover 3 leads the slide scale 6 to gradually slip following the increase of dust deposition concentration in the filter. The dust deposition concentration and operation state in the filter are directly displayed through an observation hole 9 and a number reading window 10 which are arranged on the outer shell 8 to achieve the purpose of timely maintenance.
Description
The utility model is a kind of maintenance indicator that is used for showing on the diesel engine air-strainer clean degree.
The maintenance indicator is a kind of device of representing dust accumulation degree in the air-strainer by the demonstration reading, and in the prior art, the indication reading on the filter cleaner adopts the horizontal type reading, accurate poor performance, and precision is low, and is not easy to operation.
The purpose of this utility model provides a kind of vertical direct-reading method maintenance indicator, the utility model comprises shell, compositions such as slide sign, ripple seal ring, sleeve pipe, spring, adopt the vacuum principle, with ripple seal ring and loam cake with its inner sealing, directly show the laying dust degree of air filtering by the reading window, so that in time maintain.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front view of slide sign 6 in the utility model.
Fig. 3 is the plan view of slide sign 6 in the utility model.
Fig. 4 is the front view of shell 8 in the utility model.
Fig. 5 is the plan view of shell 8 in the utility model.
As shown in Figure 1, 2, 3, the outermost layer of the utility model structure is shell 8, at shell 8 peep hole 9 and reading window 10, its subscript is arranged Vacuum 2.5 is arranged, 3.7,5.0,6.2,7.5 number, it is slide sign indicating device 6 in it, the position corresponding with shell peep hole 9 on this device, be provided with from top to bottom red, yellow, green three colour code will, be provided with the index arrow with reading window 10 corresponding positions, be equipped with the SR 2 that is huge odontoid is arranged in the corrugated sealing ring 4 in the slide sign device, this SR 2 overcoats one sleeve pipe 5, be a spring 7 in the lower end of slide sign indicating device, the other end of spring 7 is enclosed within on the external diameter of installing hole, during use, only need installing hole and air filter are connected with nut.
Below in conjunction with accompanying drawing the utility model working principle is further described: should maintain indicator by directly being connected with air-strainer, press dust cover 1 before the start, by being assemblied in the locking reset button 2 on the loam cake 3, the slide sign 6 in the indicator is resetted under the elastic force effect of spring 7; Behind the machine startup, because the seal action of ripple seal ring 4 and loam cake 3, slide sign 6 promptly along with the increase slide sign of filter cleaner inner product dust concentration along with positioning runner 13, glide gradually along location mark 11, in the downslide process, when the indicating arrow on the slide sign 6 15 points on the shells 8 in the reading window 10 institute's indexing 2.5, peep hole 9 shows green, when indicating arrow 15 pointed in the reading windows 10 the indexing 3.7-5.0 of institute, peep hole 9 promptly showed yellow, illustrates that dust increases gradually, in the machine operation procedure, scale is between the 2.5-3.7-5.0 in the reading window 10, and peep hole shows green and yellow, and filter cleaner belongs to normal working; When institute's indexing is 6.2-7.5 in the reading window 10 on the 15 sensing shells 8 of index arrow on the slide sign 6; peep hole 9 promptly demonstrates redness; show that filter cleaner need in time maintain this moment; locking reset button 2 is blocked sleeve pipe 5 automatically during maintenance downtime; make slide sign 6 can not be subjected to the elastic force effect of spring 7 and return; maintenance finishes, click dust cover 1 with hand after, slide sign 6 promptly automatically resets by the bounce-back of spring 7.
The utility model is simple in structure, and is with low cost, and reading is accurate, is applicable to that the air-strainer on the diesel engine uses.
The 1-dust cap, 2-SR, 3-loam cake, 4-corrugated sealing ring, 5-sleeve pipe, 6-slide sign, the 7-spring, 8-shell, 9-peep hole, 10-reading window, 11-positioning convex column, the 12-installing hole, 13-positioning runner, red, the green block of 14-, 15-arrow, the yellow color lump of 16-.
