Abstract
The utility model discloses a single-cylinder double-acting pump, which comprises a cylinder body. A plunger is arranged in the cylinder body; a cylinder sleeve is arranged outside the cylinder body; the front end of the plunger is connected with a piston cup; the rear end of the plunger is connected with an eccentric wheel through a connecting rod; the eccentric wheel is connected with a clutch through a gear case; the cylinder sleeve is connected with a water inlet chamber through an inlet/drainage valve; and the cylinder body is provided with an outlet joint. The plunger is movably arranged in the cylinder body through a V-shaped water seal. One side of the V-shaped water seal is provided with a grease cup. The single-cylinder double-acting pump disclosed by the utility model has a small size, a lighter weight, high pressure and high working stability. A lubricating oil adding mode is adopted by the gear case of the single-cylinder double-acting pump, and the single-cylinder double-acting pump is a comparatively ideal backpack machine pump.
Description
Technical field
The utility model relates to a kind of pump, is specifically related to a kind of single-cylinder dual-action pump.
Background technique
The single plunger duplex plunger pump is in the market comparatively general backpack machine one of pump, and the pressure height of this pump is easy to operate, spray effect is good, be fit to plant pest management and the operation of health dissipation, shortcoming is that volume is big, Heavy Weight, as the burden of bearing chance increase operator.
The single plunger duplex piston pump is also comparatively general on market, and it adopts the plastics pump housing.This pump relative weight is light, pressure is high, easy to operate, but because its gear-box adopts grease lubrication, the long-time use has certain narrow limitation, and volume is also bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of single-cylinder dual-action pump, and it can be accomplished, and volume is little, weight is light, high, the good operating stability of pressure.
For solving the problems of the technologies described above, the technical solution of the utility model single-cylinder dual-action pump is:
Comprise cylinder body, be provided with plunger in the cylinder body, cylinder body is provided with cylinder sleeve outward; The front end of plunger connects piston cup, and the rear end of plunger connects eccentric wheel by connecting rod; Eccentric wheel connects clutch by gear-box; Cylinder sleeve connects intake chamber by water-inflow and drain valve; Cylinder body sets out water swivel.
Described plunger is movably set in the cylinder body by the V-type water seal.One side of described V-type water seal is provided with grease cup.
Described cylinder body is provided with pressure regulator valve.Described cylinder body connects pressure regulator valve by air chamber.
The technique effect that the utility model can reach is:
The utility model volume is little, weight is light, high, the good operating stability of pressure.
Gear-box of the present utility model adopts the mode of lubricating oil filling, is a kind of comparatively desirable backpack machine pump.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Embodiment
As shown in Figure 1 and Figure 2, the utility model single-cylinder dual-action pump comprises cylinder body 12, is provided with plunger 5 in the cylinder body 12, the cylinder body 12 outer cylinder sleeves 8 that are provided with; The front end of plunger 5 connects piston cup 7, and piston cup 7 contacts with the inwall of cylinder sleeve 8, forms sealing;
The rear end of plunger 5 connects eccentric wheel 3 by connecting rod 4; Eccentric wheel 3 connects clutch 1 by gear-box 2;
Plunger 5 is movably set in the cylinder body 12 by V-type water seal 6, and the effect of V-type water seal 6 is to make plunger 5 liquid seepage outward not in to-and-fro motion, plays the effect of high pressure sealing;
One side of V-type water seal 6 is provided with grease cup 15, and grease cup 15 is used to increase the working life of plunger 5 and water seal 6;
Cylinder sleeve 8 connects intake chamber 11 by water-inflow and drain valve 10;
Cylinder body 12 sets out water swivel 9;
Cylinder body 12 connects pressure regulator valve 13 by air chamber 14.Air chamber 14 can reduce the pressure surge that piston cup 7 in the cylinder sleeve 8 and plunger 5 produce when alternation.
Working principle of the present utility model is:
Output shaft of gasoline engine rotates by clutch 1 driven gear axle, slows down through gear-box 2 again, makes plunger 5 reciprocating through the effect of eccentric wheel 3 by connecting rod 4; Piston cup 7 is reciprocating with plunger 5;
When plunger 5 travelled forward, piston cup 7 travelled forward thereupon; This moment, the volume of cylinder sleeve 8 front ends reduced, and liquid enters the rear portion of cylinder sleeve 8 by water-inflow and drain valve 10; Plunger 5 moves forward, and the total volume of cylinder sleeve 8 inner chambers reduces, thereby makes liquid pass through cylinder body 12 through water output connector 9 outputs;
When plunger 5 moved backward, piston cup 7 is motion backward thereupon; This moment, the volume of cylinder sleeve 8 front ends increased, and produced negative pressure, and liquid is inhaled into cylinder sleeve 8; Meanwhile the volume of cylinder sleeve 8 rear ends reduces, and liquid is exported through water output connector 9 by cylinder body 12;
The liquid of output carries out spraying operation by sebific duct and spray gun, and the amount of liquid of output this moment can be greater than the discharge rate of ejection, and redundance then is back in the liquid case by the pressure regulator valve 13 that is contained on the cylinder body 12.
Plunger 5 of the present utility model is in moving forwards or backwards process, and the process that the liquid in the cylinder sleeve 8 all once compresses is that plunger 5 produces with piston cup 7 synthetic operations.
