Abstract
The utility model relates to a novel double-cylinder plunger pump, which mainly consists of a transmission structure and a backwater inlet room assembly of bilateral plungers, wherein the transmission structure consists of a box body, a large gear, a pinion, connecting rods, an eccentric cam and plungers; two connecting rods and two plungers are respectively arranged on the left and right sides of a pump body; backwater inlet rooms of the bilateral plungers are mainly pressure chambers arranged at left and right ends of the pump body; one end of each connecting is respectively connected with one end of the left and right plungers, while the other end thereof is respectively sleeved on the eccentric cam to form concentric parallel opposite arrangement; the eccentric cam is driven by meshing of the large gear and the pinion; and the connecting rod and plunger assembly forms the homodromous right and left movement by the rotating of the eccentric cam to complete the operation of carrying out pressurizing on the liquid.
Description
Technical field
The utility model relates to agricultural machinery, is specifically related to a kind of novel duplex plunger pump, is mainly used on the motor atomizer device that liquid is pressurizeed.
Background technique
Existing traditional plunger pump all is to adopt single plunger, is cut into the U-shaped otch at the plunger center, allows eccentric cam be positioned on the U-shaped otch, by transmission, plunger is done with one heart with moving leftwards and rightwards.But after cutting the U-shaped otch on the plunger, caused plunger stress to concentrate and be difficult to eliminate,, be easy to make the plunger distortion, thereby the load of the pump housing is increased the weight of, even cause plunger stuck, caused the damage of machine when the pump housing during in work.
Summary of the invention
The purpose of this utility model provides a kind of compact structure and can produce the duplex plunger pump of crunch.
The technical solution of the utility model is: design a kind of novel duplex plunger pump, mainly the backwater room's assembly that advances by drive mechanism and bilateral plunger constitutes, wherein drive mechanism is made up of casing, gearwheel, small gear, connecting rod, eccentric cam and plunger, the quantity of connecting rod is two, the quantity of plunger is two, is located at the left side and the right of the pump housing respectively; Advance on the plunger that backwater room is set to both sides and be fixed in the two ends, the left and right sides of the pump housing, form the pressure chamber, each is connected one end of two connecting rods with an end of around side plunger, and the other end of two connecting rods is enclosed within respectively on the eccentric cam, forms concentric parallel opposed, the transmission of described eccentric cam is the engagement transmission mutually by gearwheel and small gear, by the eccentric cam drivening rod, make plunger carry out making the liquid inlet pressure chamber with moving leftwards and rightwards, carry out supercharging, thereby finish the work of plunger pump.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model;
Embodiment
As Fig. 1, a kind of novel duplex plunger pump, mainly the backwater room's assembly that advances by drive mechanism and bilateral plunger constitutes, wherein drive mechanism is made up of casing 1, gearwheel 2, small gear 3, connecting rod 4, eccentric cam 7 and plunger 5, the quantity of connecting rod 4 is two, the quantity of plunger 5 is two, is located at the left side and the right of the pump housing respectively; The backwater room of advancing of bilateral plunger is mainly the pressure chamber 6 that is located at two ends, the pump housing left and right sides, each is connected one end of two connecting rods 4 with an end of around side plunger 5, the other end of two connecting rods 4 is enclosed within respectively on the eccentric cam 7, form concentric parallel opposed, the transmission of described eccentric cam 7 is the engagement transmissions mutually by gearwheel 2 and small gear 3, by eccentric cam 7 drivening rods 4, plunger 5 is carried out with moving leftwards and rightwards, make the liquid inlet pressure chamber, carry out supercharging, thereby finish the work of plunger pump.When the utility model pump housing is worked, mechanical structure of the present utility model, thus the technical barrier that does not exist stress to concentrate has been stopped to be damaged by the pump housing that the plunger distortion causes.
