Description
Technical field
The utility model relates to a kind of lubricating fitting, particularly a kind of lubricating fitting of plungers pump plunger, is mainly used on washing machine and atomizing sprayer.
Background technique
Plunger is the critical component of plunger pump, and operationally, plunger will do high-frequency to-and-fro motion to plunger pump, meeting and crankcase body and the displacement hull friction that absorbs water, cause associated components easily to wear and tear, shorten the working life of plunger pump, oily to plunger is good measure.
If application number is disclosed in the Chinese utility model patent of 201020275445.8 " plunger lubricating device for reciprocating type plunger pump ", its structure, as shown in Figure 1.Fuel reserve tank 1 is arranged on the top of plunger 2, liquid lubricant 3 is transported to the trapped fuel pipe 5 being arranged on the positive top of plunger 2 under gravity through transport pipe 4, pass through oil dripping mouth 6 water clock again on plunger 2, oily to plunger 2, control valve 7 and filter 8 are installed on transport pipe 4 simultaneously.But this lubricating fitting has following problem: 1 structure is more complicated, it is not very suitable for being used on the washing machine of compact structure or atomizing sprayer; 2, oily needs is undertaken by control valve 7, comparatively bothers; 3, owing to carrying out water clock oiling by oil dripping mouth 6, to clean lubrication oil filtration, the complicated structure of lubricating fitting.
The plunger pump sold in the market, the structure of the lubricating fitting of its plunger, as shown in Figure 2, at outer surface cover felt oil ring 9 of plunger 2, felt oil ring 9 is fixed on water suction displacement hull 10 simultaneously, oil nozzle 11 is arranged on the top of plunger 2, oil nozzle 11 is communicated with felt oil ring 9 by the oilhole 1001 on water suction displacement hull 10, what oil nozzle 11 li was deposited is solid lubrication oil 13 solid-state at normal temperatures, when plunger 2 moves reciprocatingly, certain heat can be produced and raised temperature, the solid lubrication oil 13 of oil nozzle 11 li is made to be fused into liquid state, then be fused into liquid lubricant oil take advantage of a situation and infiltrate felt oil ring 9, lubrication is produced to plunger 2.Although the lubricating fitting of this plunger is fairly simple, but also there is following problem: 1, by the impact of heat trnasfer, after often there is solid lubrication oil 13 fusing of oil nozzle 11 bottom, water clock is over, the solid lubrication oil 13 on oil nozzle 11 top but still keeps solid-state gluing to stay oil nozzle 11 li, in order to ensure that the solid lubrication oil 13 of oil nozzle 11 li can be melted completely, general oil nozzle 11 does all smaller, the trapped fuel amount of oil nozzle 11 li is also little, need during use often to note refueling, prevent the solid lubrication oil 13 of oil nozzle 11 li from ruing out of.
So design provides a kind of lubricating fitting of new plungers pump plunger necessary.
Model utility content
Technical problem to be solved in the utility model is to provide that a kind of structural design is more reasonable, more convenient to operate, the lubricating fitting of the better plungers pump plunger of lubrication effect.
The utility model solves the problems of the technologies described above adopted technological scheme: the lubricating fitting of this plungers pump plunger, comprise felt oil ring, described felt oil ring is enclosed within plunger, and be fixed on water suction displacement hull, also comprise oil groove, described oil groove is arranged on the below of plunger, and described felt oil ring has oil ring convex, and the convex lower end of described oil ring is immersed in the liquid lubricant of oil groove.
Further, described oil groove has mounting handle, the crankcase body of plunger pump has mounting hole, described mounting handle is arranged in mounting hole.
Further, the mounting handle on described oil groove has two, and the mounting hole on crankcase body has two.
The beneficial effects of the utility model are: the utility model is by being arranged on oil groove the below of plunger, by the capillary self-priming effect that the oil ring of felt oil ring is convex, liquid lubricant in oil groove is absorbed in oil ring and lubricates plunger, structure is simple, reasonable in design, effectively solves the situation of lubricating fitting complex structure of the prior art, troublesome poeration; The self-priming effect of felt oil ring automatically carries out, lasting and balanced, no longer needs artificial switch control rule to lubricate, facilitate operation; The self-priming effect of felt oil ring has stable, lasting and balanced feature, can significantly improve the lubrication effect of lubricating fitting; Adopt mounting handle and the hard-wired mode of mounting hole, structure is simple, simplifies the structure of whole lubricating fitting.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment is the lubricating fitting of a three-cylinder plunger pump plunger.
As shown in Figure 3,4, plunger 2 is through the plunger hole 1401 of crankcase body 14, its front end is placed in the work chamber 1002 of water suction displacement hull 10, felt oil ring 9 is enclosed within plunger 2, and be fixed on water suction displacement hull 10 by jump ring 15, oil ring convex 901 outstanding is downwards arranged at the bottom of felt oil ring 9, and oil ring convex 901 is passed down through the oil-sucking hole 1003 on water suction displacement hull 10; Oil groove 16 is arranged on the below of plunger 2, oil groove 16 has mounting handle 1601, the mounting hole 1402 that crankcase body 14 has substantially horizontal to arrange, and mounting handle 1601 is inserted in mounting hole 1402, and oil groove 16 is fixed on crankcase body 14.Be placed with liquid lubricant 3 in oil groove 16, the lower end of oil ring convex 901 is immersed in liquid lubricant 3.
As shown in Figure 4, further, stable for ensureing that oil groove 16 is installed, to be provided with two mounting handles 1601 on oil groove 16.
Felt oil ring 9 is by the effect of capillary self-priming, and the liquid lubricant 3 in oil groove 16 upwards can be absorbed the oil ring circle 902 on oil ring 9 top from the lower end of oil ring convex 901, moistening oil ring circle 902 just can lubricate plunger 2; When in plunger pump working procedure, after the liquid lubricant 3 on oil ring circle 902 reduces or becomes dry, felt oil ring 9 just by capillary self-priming effect lasts, stable from oil groove 16, draw liquid lubricant 3; When on oil ring circle 902, during the fully moistening or plunger air pump inoperative of liquid lubricant 3, felt oil ring 9 because the liquid lubricant 3 at oil ring circle 902 place be in abundant moisture state, just no longer can draw liquid lubricant 3 from oil groove 16; As long as liquid lubricant 3 in oil groove 16 is sufficient, felt oil ring 9 just can automatically always, the liquid lubricant 3 at lasting, stable guarantee oil ring circle 902 place is in a constant moisture state, to the surface of plunger 2 with highly stable lubrication.
Above are only embodiment of the present utility model, the design of this model utility is not limited thereto, all according to the equivalence done of structure, feature and principle described in the utility model design or simple change, is included in the protection domain of the utility model patent.
