Abstract
The utility model discloses a manual high-pressure pump. A piston is assembled on the outer tower of the piston, a piston spring sheet is installed on the inner tower of the piston, and a piston with spring sheet is formed; the piston is expended following with the spring sheet under the action of the spring sheet after the piston is wore out, the perfect matching between the piston and the cylinder wall is guaranteed, and the long-time stable flow, the stable delivery lift and the stable suction lift of the manual high-pressure pump can be guaranteed; the manual high-pressure pump with high delivery lift can be used for water pumping, sprinkling irrigation, agricultural chemicals sprinkling, and agricultural automobile and agricultural implement washing; the manual high-pressure pump can be used to install a simple tap water for a lower building.
Description
The utility model belongs to the manually operated type reciprocating pump, particularly relates to the Sealing of piston.
The piston of existing manually operated type reciprocating pump has destroyed the gap between piston and the casing wall because to-and-fro motion is worn and torn easily after the wearing and tearing, influence the flow of pump, can not guarantee the suction journey and the lift of pump.Often change piston, influence the efficient of pump and the maintenance expenses of increase pump.
The purpose of this utility model is to develop a kind of simple in structurely, can guarantee between piston and the casing wall good fitly again, can recover the piston spring sheet in gap behind the piston wear automatically.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is the plan view of piston spring sheet;
Fig. 4 is the sectional view of piston spring sheet;
Fig. 5 is the I partial enlarged drawing.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
High-pressure hand pump is made of piston, cylinder body, connecting rod etc., and piston 2 usefulness piston outriggers 1 of the present utility model, piston internal frame 4 and axle 6 are fixed in the cylinder body 8, are drilled with four apertures along the circumference quartering in the middle of the outer wall of piston internal frame 4.Piston spring sheet 3 is the tapered opening annulus, and the place of corresponding aperture with internal frame is drilled with four apertures, and rivet 9 is fixed in the aperture, and the other end of rivet can endwisely slip in internal frame.One pin-and-hole is arranged at internal frame top, connects with pin 7 and axle 6, and screw 5 and axle 6 scyewed joint are arranged at outrigger top.10 is one-way valve, and seat is in the centre of outrigger and internal frame.
Advantage of the present utility model and good effect: adopt this piston spring sheet, behind the piston wear under the effect of steel disc also swollen thereupon rising, can guarantee good fit between piston and the casing wall, can guarantee pump more often between regime flow, thereby guarantee stable lift and inhale journey.The utility model can prolong the working life of piston, reduces the amount of maintenance and the maintenance expenses of pump.This pump not only can pump up water, can also spray, spray medicine, flushing agricultural automobile, agricultural machinery and implement, can also adorn simple running water at lower building.
