Abstract
The utility model relates to a water pump comprising a shell on which a water inlet and a water outlet are arranged, wherein a cylinder body is arranged inside the shell; two pistons are arranged inside the cylinder body and each piston is connected with a driving mechanism through a piston rod; the middle, the front end and the rear end of the cylinder body are respectively provided with a through hole and all the through holes are connected with the water inlet and the water outlet on the shell; the three ends of the through holes are respectively provided with a water seal door; and the two pistons are symmetrically arranged inside the cylinder body and respectively connected to a left screw rod and a right screw rod. Therefore the flow rate of the water pump is improved and the water pump has the characteristics of great flow rate and high pressure.
Description
Technical field
The utility model relates to a kind of water pump.
Background technique
At present, the water pump kind is many, and structure has nothing in common with each other, and gear pump, vane pump, plunger pump etc. are arranged, and as plunger pump, comprises housing, is provided with plunger in the housing, and plunger connects driving mechanism, and the to-and-fro motion pressurized water of plunger is too paramount.The not enough here of its existence is that pressure is big, but flow is little.
The model utility content
Its purpose of the utility model just is a kind of water pump is provided, and has the advantages that flow is big, pressure is high.
The technological scheme that realizes above-mentioned purpose and take, comprise housing, height has intake-outlet on the housing, be provided with cylinder body in the housing, be provided with piston in the cylinder body, connect driving mechanism through piston rod, described cylinder body middle part and front end and back end respectively are provided with a through hole and connect water intake and water outlet on the housing, described three through hole ends are provided with the water seal door, are symmetrical arranged two pistons in the described cylinder body, and connect left-handed silk and dextrorotation screw mandrel respectively.
Compared with prior art, the utlity model has following advantage,
Owing to adopted the double-piston to-and-fro motion and compressed the structural design of water outlet continuously, thereby it is big to have a flow, the characteristics that pressure is high.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic front view.
Fig. 2 is this device driving mechanism schematic representation.
Fig. 3 is this device linkage mechanism schematic representation.
Embodiment
Comprise housing, housing is provided with intake-outlet, be provided with cylinder body in the housing, be provided with piston in the cylinder body, connect driving mechanism through piston rod, as shown in Figure 1, described cylinder body 5 middle parts and front end and back end respectively are provided with a through hole and connect water intake 1 and water outlet 8 on the housing 6, described three through hole ends are provided with water seal door 7, are symmetrical arranged two pistons 4 in the described cylinder body 5, and connect left-handed screw mandrel 9 and dextrorotation screw mandrel 3 respectively.
Described left-handed screw mandrel 9 and dextrorotation screw mandrel 3 are provided with nut 2, and connect linkage mechanism 12.
Described driving mechanism comprises follower 10, and as shown in Figure 2, follower 10 axle heads are provided with follower wheel 11 and connect linkage mechanism 12, and described driven runner 11 connects driven runner 2 14 through belt 13, and driven runner 2 14 connects linkage mechanism 12.
Working principle: follower 10 rotates, drive driven runner 11 and driven runner 2 14, through linkage mechanism 12(attaching nut) 2, thereby drive left- handed screw mandrel 9 and 3 rotations of dextrorotation screw mandrel, and promotion piston 4, to-and-fro motion, when piston 4 relative movement, water in the compression piston chamber advances from water outlet 8 from water intake 1, and simultaneously, the water shutoff door 7 at cylinder body 5 two ends is opened, the water of water intake 1 flows out and connects the water outlet 8 that passes on the housing 6 from the through hole at cylinder body 5 two ends, when piston 4 move toward one another, the water seal door 7 of cylinder body 5 water inlets is closed, and the water in the compression cylinder 5 is communicated with water outlet 8, thereby realize continuous water outlet, that is to say that in the to-and-fro motion process of piston, the water outlet place all is in the water outlet state.
