Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the principle schematic diagram. of piston pump described in embodiments of the invention one, two, four.
Specific embodiment
Embodiment one：
The present embodiment is a kind of high-lift piston pump of water attack drive-type, as shown in Figure 1.The present embodiment includes：With level
The inverted T-shaped valve body of section 1 and vertical section 2, one end of described horizontal segment is hydraulic pressure water inlet 101, and the other end is pressure output
102, the bottom of described vertical section is connected with horizontal segment, and top arranges water attack valve 3, described vertical section sectional area from bottom to top
Gradually increase, form enlarging；Described pressure output and 4 UNICOM of linear actuator, are provided with described linear actuator and connect with piston
The power piston 401 and back-moving spring 403 of bar 402, described piston rod are connected with the pump water piston 501 being located in pumping cylinder 5,
Described pumping cylinder is connected with water injection pipe 7 and water-supply-pipe 6, and described water injection pipe is provided with water filling check valve 701, described water-supply-pipe
It is provided with water delivery check valve 601.
The operation principle of the present embodiment is：
Water attack valve is closed and produces water attack, pressure rise in valve body, and propulsion power piston is on the right side of linear actuator（By the paper of Fig. 1
The left and right sides that face determines）It is mobile, while driving water body in pump water piston compression pumping cylinder, the water body in pumping cylinder to arrange from water delivery check valve
Go out.
When in the pump housing, surge pressure is reduced, power piston is moved under back-moving spring and inside and outside differential pressure effect on the left of linear actuator
Dynamic, while driving pump water piston to move on the left of pumping cylinder, pumping cylinder inner volume increase pressure reduces, and extraneous water body is made in atmospheric pressure
Pumping cylinder is flowed into from water filling check valve with.
Water attack valve is periodically opened and closed, and said process reruns.
It is assumed that the distance of piston movement（Stroke）, the area of power piston, reciprocal cylinder diameter, pump water piston
Area, pumping cylinder diameter, then the theoretical discharge opeing volume that two pistons often make a round tripFor：
,
Water attack valve produce maximum surge pressure be, then maximum pump up water pressure（Head）For：
WhenWhen,, so as to the ratio for passing through to change linear actuator and pumping cylinder sectional area can improve the water that pumps up water
Head.
Advantage of this embodiment is that：Traditional water hammer pump lift is less, the high-lift work of water attack drive-type described in the present embodiment
Plug pump can meet the demand that different lifts supply water by change linear actuator and the ratio of pumping cylinder sectional area.
Hydraulic pressure water inlet described in the present embodiment should connect the water body with pressure.Water is set in upstream under normal circumstances
Pond is connected with hydraulic pressure water inlet by pond using an inclined hard pipeline.The height of the pump housing should be less than water level in pond
Highly, the water level in pond is made to produce pressure to the water body in the pump housing.
The pump housing of inverted T-shaped should be the pump housing of hard, can bear the pressure of water attack without deforming.The enlarging of vertical section can
Being gradually extend tubaeform, or the step shape in the extension suddenly of a certain section.
Water attack valve can be the check valve with spring reset, guide the opening and closing of flap using cross hang and guide post.
Water attack valve is arranged on the top of vertical section, has current and flows out from water attack valve, if entirely during opening and closing
The pump housing is invaded and is ducked in drink, then without manage these spilling current, if the pump housing is arranged on anhydrous downstream pump bracket, need by
The current that the part is overflowed are guided to downstream.
Linear actuator and pumping cylinder, should be with atmospheres in the side without water pressure, it is to avoid the air in cylinder forms cup to piston
Pressure, reduces service efficiency.Or linear actuator is one side closed without hydraulic pressure, air chamber is formed, the elasticity by the use of air is used as again
Position spring.
Preferably connected with fixed connecting rod between pump water piston and power piston, but for examining for manufacturing process
Consider, can consider that chain connection is used between two cylinder rods.
Described back-moving spring can then use cylindrical helical stage clip, be arranged on the back pressure side of power piston, also may be used
With the flexible member using other forms, use as back-moving spring.
Embodiment two：
The present embodiment is the improvement of embodiment one, is refinement of the embodiment one with regard to linear actuator and pumping cylinder.The present embodiment institute
The linear actuator and pumping cylinder stated is provided with breather 8, the breather by the back pressure side of power piston and pump water piston and atmosphere,
As shown in Figure 1.
Invade what is ducked in drink during the pump housing described in the present embodiment, and the piston back pressure side of linear actuator and pumping cylinder is all closing
's.In the back pressure side facility breather of linear actuator and pumping cylinder, by the back pressure side of two cylinders and atmosphere, it is to avoid air is to piston
Motion artifacts.
Embodiment three：
The present embodiment is the improvement of embodiment one, is refinement of the embodiment one with regard to back-moving spring.Described in the present embodiment
Back-moving spring is provided in the helical compression spring of linear actuator back pressure side.
Helical spring can be helical spring, or cone shaped spring.
Example IV：
The present embodiment is the improvement of embodiment one, is that embodiment one is refined with regard to pumping cylinder.Pumping cylinder described in the present embodiment is also
Water injection valve 9 is provided with, as shown in Figure 1.
In the starting stage that piston pump is started working, no water in pumping cylinder, only air will such as be directly initiated, may
Because it is relatively time-consuming to pump out air, for this purpose, the present embodiment arranges water injection valve in pumping cylinder, before starting pumping, will note in pumping cylinder
Full water, makes pumping cylinder in initial working stage, is directly entered pump water.
Finally it should be noted that above only unrestricted to illustrate technical scheme, although with reference to preferable cloth
Put scheme to be described in detail the present invention, it will be understood by those within the art that, can be to the technology of the present invention
Scheme（The shape of the such as pump housing, the mounting means of two cylinder bodies, mode of water delivery etc.）Modify or equivalent, and not
Depart from the spirit and scope of technical solution of the present invention.
