The plunger piston pump is characterized in that the pump body is a case body; the inside of the pump body is divided into a crankcase and a corrugated pipe case; a spacing part between two cases is provided with a steel cylinder which is provided with a plunger piston; one end of the plunge piston is provided with a connecting rod pin; the other end of the plunger piston is provided with a threaded stud; the crankcase is provided with a crank shaft; the connecting rod is a rod with a small head and a large head; the large head is hinged with the crank shaft; the small head is hinged with the connecting rod pin; two ends of the corrugated pipe are respectively provided with a ring seat; the ring seat on one end of the corrugated pipe is connected with the plunger piston by the threaded stub; and the ring seat on the other end of the corrugated pipe is connected with the corrugated pipe case by a bolt. In operation, the lower half part of the plunger piston is immersed into lubricating oil and has the function of self lubrication; and the crank shaft rotates and throws the lubricating oil to the upper part of the plunger piston for auxiliary lubrication, thereby realizing self-help lubrication. The self-help type lubrication high-pressure plunger piston pump has a simple structure, good lubricating effect and high working efficiency.
Description
Technical field
The utility model relates to machinery manufacturing technology field, is a kind of pump that is used for high-pressure fog machine, washing machine, particularly a kind of self-service lubricated high-pressure plunger pump.
Background technique
Plunger pump of the prior art is realized lubricated and sealing with the filling butter between the pump housing and plunger and the mode of establishing V-shaped seal ring.The problem that this kind mode exists is: the butter of need annotating at any time during work, seal ring is changed frequent, cause inefficiency, maintaining to be wasted time and energy, and careless slightly meeting leads to a disaster.
Summary of the invention
The purpose of this utility model is a kind of self-service lubricated high-pressure plunger pump that provides at the deficiencies in the prior art, and it adopts self-service mode to make plunger lubricated, and it is simple in structure, high lubricating effect.
The concrete technological scheme that realizes the utility model purpose is:
A kind of self-service lubricated high-pressure plunger pump, it comprises the pump housing, connecting rod, bellows, the pump housing is a casing, be divided into crankcase, bellows box in it, its two casees intervals are provided with steel cylinder, are provided with plunger in the steel cylinder, and plunger one end is provided with link pin, the other end is provided with stud bolt; Be provided with bent axle in the crankcase; Connecting rod is big or small head rod, and its major part and bent axle are hinged, microcephaly and link pin are hinged; The bellows two ends are respectively equipped with ring seat, and an end ring seat is connected with plunger through stud bolt, and an end ring seat is connected through screw with bellows box; The pump housing is provided with filler plug, end face is provided with end cap, and end cap is connected with crankcase through screw; End cap is provided with oil meter, and the end cap below is provided with oil drain plug.
A described end ring seat is provided with two joints, is respectively equipped with one-way valve in two joints.

Description of drawings
Fig. 1 is the utility model structural representation
Embodiment
Consult Fig. 1, the utility model comprises the pump housing 1, connecting rod 2, bellows 3, and the pump housing 1 is a casing, be divided into crankcase 11, bellows box 13 in it, its two casees intervals are provided with steel cylinder 12, are provided with plunger 9 in the steel cylinder 12, and plunger 9 one ends are provided with link pin 10, the other end is provided with stud bolt 15; Be provided with bent axle 8 in the crankcase 11; Connecting rod 2 is the CONCENTRIC REDUCER connecting rod, and its major part 21 and bent axle are 8 hinged, microcephaly 22 is hinged with link pin 10; Bellows 3 two ends are respectively equipped with ring seat 36,38, and ring seat 36 is connected with plunger 9 through stud bolt 15, and ring seat 38 is connected through screw 35 with bellows box 13; The pump housing 1 is provided with filler plug 6, end face is provided with end cap 5, and end cap 5 is connected with crankcase 11 through screw 16; End cap 5 is provided with oil meter 4, and end cap 5 belows are provided with oil drain plug 7; Ring seat 38 is provided with joint 30,31, is respectively equipped with one-way valve 39 in the joint 30,31.
The utility model is work like this: bent axle 8 whenever rotates a circle, connecting rod 2 drives plunger 9, back ring seat 36 and bellows 3 to-and-fro motion once, when ring seat 36 compress bellows 3, one-way valve 39 in the outlet connection 30 is opened, one-way valve 39 in the inlet attack 31 is closed, pressure in the bellows 3 raises, and the compressing material is by outlet connection 30 ejections; When ring seat 36 discharged bellows 3, the one-way valve 39 in the outlet connection 30 was closed, and the one-way valve 39 in the inlet attack 31 is opened, and the pressure in the bellows 3 descends, and material is sucked in the bellows 3 by inlet attack 31, circulated with this; In the work, the lubricated form of plunger is: open filler plug 6, add lubricant oil in crankcase 11, make the position of oil meter 4 on the lubricant oil liquid level arrival end cap 5, in the Lower Half floodlubrication oil of plunger 9; During work, because the Lower Half of plunger 9 is dipped into the function that has self-lubrication in the lubricant oil, bent axle 8 rotates drivening rod 2 motions in addition, and connnecting rod big end 21 gets rid of lubricant oil to plunger 9 tops and carries out lubrication assistant, finishes self-service lubricated; For preventing that lubricant oil from entering bellows box 13 by crankcase 11, oil sealing 14 plays the effect of isolation lubricating oil.
