Abstract
The utility model relates to an electric grease lubricator comprising a grease storage drum, a motor, a speed reducing assembly and a plunger pump assembly, wherein a plunger cylinder of the plunger pump assembly is respectively provided with a grease inlet and a grease outlet. The electric grease lubricator is characterized in that the plunger cylinder is provided with a deflation valve which is close to one side of the grease outlet of the plunger cylinder so that high-pressure air inside the plunger cylinder is easier to exhaust; besides, the bottom of the grease storage drum is provided with a filter screen, and the filter screen can filter oils entering the plunger cylinder to prevent impurities from entering the plunger cylinder and crush large air bubbles to enhance the exhaust effect and the passing rate of the oils. The deflation valve is arranged in the plunger cylinder so as to lead direct deflation, thereby effectively exhausting air entering the plunger cylinder and enhancing the greasing efficiency.
Description
Technical field:
The utility model belongs to the machine tool field, particularly a kind of improvement of electric butter oil gun.
Background technique:
Existing hand-held equipment to mechanical device interpolation butter has hand grease gun and electric grease gun two classes.Electric butter oil gun structure includes fuel tank, motor and deceleration assembly and plunger pump assembly.Motor output shaft connects an eccentric shaft after reduction gear, by the slide block in the eccentric shaft drive plunger assembly, slide block drives plunger and finish to-and-fro motion in plunger case, reaches the purpose of high pressure oiling.Plunger case offers oil outlet and filler opening respectively, and oil outlet is provided with one-way valve, and filler opening is communicated with fuel tank.Unavoidable entrained air during charge of oil for exhausting air, all is provided with bleed valve at fuel tank and plunger case joint, so that discharge near the air the filler opening, in order to avoid air enters in the plunger case.In a single day air enters the efficient that promptly can influence oiling in the plunger case, perhaps for the moment is difficult to pump oil and comes.Trace it to its cause, the air ratio butter has higher compression ratio, be difficult to discharge from the oil outlet one-way valve, and the oil in the oil tube also is difficult to.
Summary of the invention:
The purpose of this utility model is a kind of electric butter oil gun of establishing bleed valve in plunger case of design.
Technical solutions of the utility model are achieved in that a kind of electric butter oil gun, comprise fuel tank, motor and deceleration assembly and plunger pump assembly, be respectively equipped with the filler opening and the oil outlet that are communicated with fuel tank on the plunger case in the plunger pump assembly, it is characterized in that plunger case is provided with a bleed valve.And this bleed valve is closely by plunger oil outlet one side, makes easier the giving off of high-pressure air in the plunger case.
Described bleed valve is made up of valve seat, valve pocket, ball and the jackscrew of plunger case disjunctor, and ball is placed in the valve pocket, by jackscrew ball is conflicted on air vent.When oil gun can't be got oil, only need gently revolve jackscrew, compressed pressurized gas can be discharged from the ball gap in the plunger case, and during the plunger retraction, ball can be blocked air vent again rapidly, avoids air to flow into, and reaches the purpose of venting; Venting screws tight jackscrew and gets final product after finishing, and avoids butter to discharge from air vent.
The utility model is established bleed valve in plunger case, make that venting is more direct, effectively discharges the air that enters in the plunger case, improves oiling efficient.

Embodiment:
See figures.1.and.2, the electric butter oil gun comprises fuel tank 1, motor and deceleration assembly 2 and plunger pump assembly 3.Motor 21 tops are provided with storage battery 22 or power supply adaptor, and motor lower portion is connected with retarder 23, in the elongated slot of the slide block 31 of retarder 23 output eccentric shafts 24 insertion plunger piston assembly, make rotatablely moving of eccentric shaft 24 convert the round straight line motion of slide block 31 to; Plunger 32 is hung on the slide block 31, drives plunger 32 by slide block 31 and does compression and pumpback action along plunger case 33.In plunger pump when work,, plunger 32 pumpbacks are during to plunger case 33 filler openings 34, and the butter in the fuel tank 1 flows into rapidly in the plunger case 33 under fuel tank 1 self spring pressure and plunger case 33 negative pressure double actions; During plunger 32 compressions, the oil pressure in the plunger case 32 increases to when opening oil outlet 35 one-way valves 36, and butter can go from oil outlet 35 pumps.
Plunger case 33 in the plunger pump assembly 3 is except being provided with filler opening 34 and oil outlet 35, also be provided with a bleed valve 4 near on the plunger case 32 of oil outlet 35, this bleed valve 4 is by forming with valve seat 41, valve pocket 42, ball 43 and the jackscrew 44 of plunger case 33 disjunctors, ball 43 is placed in the valve pocket 42, by jackscrew 44 ball 43 is conflicted on air vent; Offer an exhaust port 45 on the valve seat 41 between ball 43 and the jackscrew 44, this exhaust port 45 is communicated with valve pocket 42 and atmosphere, so that more smoothly air is discharged.During venting, only need to transfer loose jackscrew 44, compressed air in the plunger case 33, its pressure can't back down one-way valve 36, can't in time discharge, and can borrow this moment air vent to discharge; During the plunger pumpback,, under suction function, block air vent rapidly because ball 43 closely leans against the air vent place, avoid air to sneak into once more, when exhaust port 45 is discharged, illustrate that plunger case 33 interior air drain as butter, can tighten jackscrew 44, close bleed valve 4, finish whole venting action.
As Fig. 1, be provided with a filter screen 11 in fuel tank 1 bottom, this filter screen 11 can filter the oil product that enters in the plunger case 33, and one can avoid impurity to enter, and it two can be broken than gross blowhole, strengthens exhaust effect.
This bleed valve is arranged on the plunger case, and tradition is provided with bleed valve at the filler opening place that fuel tank is communicated with plunger case, and its discharge efficiency is higher, and is more direct.
