The utility model relates to a kind of reciprocating pump that pumps up water automatically that does not only need the other energy with source water low-pressure head.

As all a kind of reciprocating pumps of pump class, the same with other pump class, all to drag with external impetus, this is at the common mechanical project handbook, motor engineering handbook (China Machine Press's publication), in the pump series products catalogue known record being arranged all, owing to its art designs reason, must be following result: even in bleak and desolate mountain area, abominable remote water scene, for the also necessary dynamic power machine that is equipped with of the operation of pump, as motor, internal-combustion engine, steamer etc., and corresponding supporting energy device: generating, transmission of electricity, power transformation, controller switching equipment or fuel oil, coal-fired deposit haulage device etc.During pump operation, even arduous work living condition, abominable living environment also will have the electrician operator not have round the clock on duty of branch, and consequently equipment investment is many, consumes energy, and operator's operating conditions is abominable; Some complicated no road does not have the job site in signs of human habitation area again, the sentry post, special plantation, plant, the energy and power facility that difficulty is set is very big, invest more, even, can't provide the power and the energy because of topography and geomorphology restriction, there is water not have pump and influences regional development, moreover the noise of power equipment causes very disadvantageous consequence to environment sometimes, and is that have or even unallowed.

It is big that the purpose of this utility model is to solve technically above-mentioned investment, big energy-consuming, or, energy free do not have pump because of having caused water, can't supply water, the electrician operator will be under abominable labor life condition on duty waiting for, integrated operation cost height, noise Da Zhu problem, provide a kind of without extra power and power facility, be power with water source low-pressure head only, automatically the low-pressure head with source water improves into the high pressure head, with as water supply, and control stroke directions voluntarily, the continuous reciprocating pump that pumps up water automatically, this reciprocating pump that pumps up water automatically after the normal operation of Installation and Debugging, need not be waited for by electrician's pumper round the clock, because of its structure, material is special, the operation noise is extremely low, and it is few to reach the comprehensive method of investment, and operating cost is low, unmanned, purposes such as hidden are good in peace and quiet.

For achieving the above object, automatically the reciprocating pump that pumps up water of the present utility model, utilize the water of water source low-pressure head or the liquid of other low-pressure head, act on the big gross thrust that produces on the large-area piston, transfer function is on small area piston and produced a high pressure water or a high pressure liquid again, it is constructed as follows: 1 control cylinder: its middle part be provided with and insert low-pressure head water source, make the piston stroke break-in about two groups, the every group water inlet that one or several is arranged, every group of water inlet is all on same plane perpendicular to shaft axis; The two end part of control cylinder respectively have one group, every group of one or several weep hole, every group of weep hole all on same plane perpendicular to shaft axis, be used for the source water work done after release discharge outside the control cylinder.On the coaxial inner conductor of the outside, control cylinder two ends, respectively connect and adorning big pumping cylinder and interior supporting big piston thereof, on the coaxial inner conductor of the outside, big pumping cylinder two ends, respectively connect again and adorning little pumping cylinder and interior supporting small piston thereof: require the quantity of big pumping cylinder and big piston thereof and the quantity of little pumping cylinder and small piston thereof to increase and decrease according to operating conditions, each 1 at least of each two at least of big pumping cylinder and interior supporting big piston thereof, little pumping cylinder and interior supporting small piston thereof.External diameter is less than 1 piston cylinder of control cylinder internal diameter, pass from the control cylinder shaft axis, and the passing of coaxial inner conductor, connect and adorning each big or small pumping cylinder and big small piston, there is axial hollow minute chamber piston cylinder inside, this minute the chamber shape of cross section, determined the shape of the cross section of piston cylinder, piston cylinder and the vertical connecting place of each big piston are that the every side in root both sides of each big piston has one group, every group has 1 or several paddle hole, each branch chamber of piston cylinder is being communicated with 1 paddle hole of each big piston root, piston cylinder passes the stage casing of control cylinder part, also to pass the reversing slide valve that is positioned at the control cylinder middle part, but the axial arrangement length of reversing slide valve is 2 groups of water inlets on the switch control cylinder only, this reversing slide valve together with piston cylinder with control cylinder be divided into annular cylinder shape about 2 branch chambeies, piston cylinder passes two ends, the left and right sides section of control cylinder part, also to pass a left side that is positioned at two ends, the control cylinder left and right sides respectively, right draining guiding valve, on a left side, pairing being positioned on the piston cylinder outside diameter wall in position between right draining guiding valve and the selector valve, a left side is arranged, right 2 groups of symmetries, every group 1 or several paddle holes, every group paddle hole is all on the same cross section perpendicular to the piston cylinder shaft axis, 1 paddle hole of piston cylinder only communicates with 1 branch chamber of piston cylinder, again only and each left side, big piston root both sides, 1 paddle hole of right position opposite communicates, be used to carry the setting-out that unloads after source water and the work done, the paddle hole sum equals the branch chamber sum in the piston cylinder on the piston cylinder, equals the paddle hole sum of 1 big piston root both sides again.2 groups of elastic limit device about both sides, position, paddle hole hole, the piston cylinder left and right sides respectively have, being used to promote the left and right of reversing slide valve moves and left and right draining guiding valve moving to open row water hole direction, and difference switch water inlet and open row water hole, elastic limit device is made with elastic material, its structure type is for producing distortion and absorption pressure energy after being subjected to arbitrary guiding valve resistance, being subjected to resistance to get over the bigger and absorption pressure of large deformation can be more; Reversing slide valve is made by organic composite material, be controlled by the left and right of elastic limit device and move, thereby source water is alternately entered enter respectively again behind the water inlet, the left and right sides of control cylinder control cylinder about the branch chamber, to finish the left and right sides stroke of piston.Described left and right draining guiding valve is made by organic composite material, and the one end is in control cylinder and have little flange, the other end to extend in the adjacent big pumping cylinder and be provided with big flange, and big piston is passed the draining guiding valve and closed weep hole.In the one stroke in office, for example in the right lateral journey, right draining guiding valve has been opened right weep hole under the effect of moving to right of right elasticity limit device, in this same right lateral journey, move to right under the big piston effect of left bank neatly valve in adjacent big pumping cylinder and closed the left bank water hole.When piston carried out the left lateral journey, finishing the exercises identical with the right lateral journey was that direction is opposite.The inboard restriction piece that excessive left and right each place of restriction reversing slide valve displacement is housed at the control cylinder middle part.The outlet valve when being used for the sky pump startup all is equipped with on the big pumping cylinder wall of the both sides of each big piston and the outside of control cylinder two ends weep hole.The water inlet one-way valve that is no less than 2 is housed on the little pumping cylinder wall of each small piston both sides and is no less than 2 the water one-way valve that goes out, promptly have a water inlet one-way valve at least and have at least one to go out water one-way valve in the arbitrary side of small piston.Waste pipe that is connected in addition and intake pipe, and connect the outlet pipe of output high pressure water and the valve on each pipe.

Automatically the method for operation of reciprocating pump of pumping up water is as follows: when low-pressure head source water flow through certain side such as water inlet, right side, after entering the annular cylinder shape branch chamber on control cylinder right side, the right paddle hole of the piston cylinder by being provided with axial hollow minute chamber, enter in the big pumping cylinder in each big piston left side, meanwhile, control cylinder right side weep hole is closed by right draining guiding valve; Big piston begins to move to right under source pressure, and the small piston that links to each other with piston cylinder on the coaxial inner conductor moves to right in little pumping cylinder, is A1.cm as the area of big piston ², the pressure head of suffered source water is P1.kg/cm ², the small piston area is A2.cm ², the counter-force on the small piston is that the delivery pressure head is P2.kg/cm ²P1 * A1=P2 * A2, be that the gross thrust of the suffered low-pressure head of big piston and the total pressure of the high pressure head that small piston is exported equate, so P2=P1 * A1/A2, because of A1＞A2, P2＞P1 then is H2 as the drag overall head of the reciprocating pump that pumps up water automatically itself, as long as needing with head is H1, then H2+H1＜P2/ γ. (γ: the proportion of transporting water or liquid) be the water that small piston can be confessed the high pressure head.When continuing to make big piston, source water moves to right, in the time of will be near right dead point, the left side spacing attaching of group elasticity on the piston cylinder contacts reversing slide valve, because of being full of the back pressure resistance that source water produces in the right chamber of the control cylinder on external diameter Sealing surface friction drag in the reversing slide valve and its right side, reversing slide valve wouldn't can slippage, but big piston continues to move to right and makes left side group elastic limit device press short distortion and absorption pressure energy; Meanwhile, right group elastic limit device on the piston cylinder, touch right draining guiding valve, a because left side, right draining guiding valve has all had the designed unidirectional small damping structure of the utility model, make right elastic limit device also produce extrusion-deformation and absorbed the pressure energy, damping structure also makes the right draining guiding valve speed V2 that moves to right be lower than the speed V1 that big piston moves to right, but it is fast during near right dead point, because of weakening of damping effect, the speed V2 of right draining guiding valve is under the acting in conjunction that pressure can discharge and piston moves to right that right elastic limit device absorbs, the speed that the moves to right V1 that surpasses big piston, both rigidly connected V2＜V1 when contacting right draining guiding valve by right elastic limit device, to fast V2＞V1 after damping weakens during near right dead point, thereby rapidly right draining guiding valve is moved to right, open right weep hole, source water in right chamber of control cylinder this moment and the big pumping cylinder is very fast from right weep hole release discharging, because of control cylinder parts the rapid draining in chamber on the right side, the reduction rapidly of this minute back lining pressure, the acting in conjunction power that pressure energy that left side elastic limit device absorbs and piston move to right, because of only overcoming the frictional resistance of the Sealing of reversing slide valve, the then very fast speed with V3 is pushed reversing slide valve to right dead point to right restriction piece place, before near the dead point, V3＞V2＞V1 then, so commutation, each guiding valve of draining and piston arrive the dead point simultaneously, reversing slide valve is shifted to the right to right dead point, the right water inlet of control cylinder is closed, water inlet, a left side is open, the while big piston stops to move to right and changes and moves to left, in the same therewith right lateral journey, the big piston in control cylinder left side moves to right the left bank neatly valve that the big flange in end extends in the big pumping cylinder, close the left bank water hole, source water enters big piston right side promotion big piston from left water inlet by control cylinder chamber, a left side and piston cylinder branch chamber and moves to left, finish the left lateral journey, will be near before the left dead point, a left side, right elastic limit device can repeat all processes of right lateral journey, after arriving left dead point, begin the right lateral journey again.The small piston that connect on the coaxial inner conductor that is contained in piston cylinder this moment is made same moved further in little pumping cylinder, when small piston moves to right the water inlet closed check valve on right side in the little pumping cylinder, to go out water one-way valve open and go out high pressure water, the water inlet one-way valve water inlet in the left side of small piston, the water outlet closed check valve; The dextrad of small piston supplies water and finishes when big piston arrives right dead point; The water-in and water-out one-way valve of the left and right sides of little pumping cylinder repeats the process of moving to right when big piston moves to left, and replaces the function that reciprocal stroke has been finished the reciprocating pump that pumps up water automatically like this.In sum as can be known: the control power that described big piston continues work done also only is from the source water pressure head; Being the big piston that persistent movement, the work done source water being provided and finishing all paddle holes that merit is unloaded setting-out, all is moving with stroke; Carrying source water and release draining is that piston cylinder is finished with the moving pipe of stroke; The source water that ground is being fixed is to be undertaken by the control cylinder annular cylinder shape that is full of source water chamber transition in left and right 2 minutes to being the conveying of piston cylinder with the moving pipe of stroke; The release draining of finishing merit is via being that piston cylinder is alternately discharged the pump housing through the transition in the former annular cylinder shape chamber of control cylinder again with the moving pipe of stroke.

Automatically the reciprocating pump that pumps up water of the present utility model, the pump class comparison with prior art has following advantage: dynamic power machine that need not drag and supporting subsidiary engine thereof, can move without extra power and corollary equipment thereof, its manufacturing process is fairly simple, reduces investment outlay, and the integrated operation cost is low, need not electrical equipment, safe and reliable, thus need not electrician's pumper on duty, again because of the direct bump friction between the no metal, so noise is low suitable hidden, helps the environment peacefulness; In the occasion that does not have maybe should not solve the energy; construct as isolated area, mountain area highway traffic infrastructure; forest tree planting reservation park; extraordinary plantation; plant can make water supply equipment; its preceding unpowered equipment that tops out of building construction; during water-supply line; can be used as the interim water water pump of high-rise construction; high residential building fire-fighting stand by pump (cutting off the electricity supply earlier during fire); the national defence frontier sentry; micro-communication station; air-satellite stations etc. are made water supply equipment; as long as have the low pressure water source to comprise the mountain stream flowing water of half way up the mountain, use the reciprocating pump that pumps up water automatically of the present utility model all can obtain high pressure head output water.

As seen from Figure 1, Figure 2, the utility model reciprocating pump that pumps up water automatically must be discharged air in the pump chamber before water flowing, the nearly dead center position, both sides of the big piston 29,46,67,88 in each big pumping cylinder 28,45,68,82 and the two end part of control cylinder 1 are provided with 1 outlet valve 27,30,44,49,58,66,80,81 and 50,59 respectively, closing gate valve 47,57 before the water flowing,

open gate valve

15,21,83 and 48,53, all outlet valves 27,30,44,49,58,66,80,81 and 50,59 are all open.The reciprocating pump integral body of will pumping up water automatically holds up perpendicular to ground, all can on the left and right, with the right upwards is example, (left side) dead point is down all arrived in whole big pistons and the

little match

25,42,94,87 of living under the deadweight effect, arrive at down (left side) dead point under the effect of right draining guiding valve 99 by deadweight and big piston 67 and close right weep hole 65, reversing slide valve 55 slides into the position of (left side) dead point restriction piece 2 down under the effect of right elastic limit device 63 and deadweight, right water inlet 56 is opened, and left water inlet 54 is closed; Left bank neatly valve 5 arrives at (left side) dead point down under left elastic limit device 52 and deadweight effect, left bank water hole 51 is open.Be in normal operating condition with integral pump placement level this moment: low-pressure head source water is entered pipe 22 by gate valve 83, wait to manage 22 and be full of closing gate valve 21 behind the water, after simultaneously this low-pressure head source water being entered the right water inlet 56 of control cylinder 1 again through intake pipe 60, control cylinder 1 right chamber is full of water gradually and enters in the annular chamber that little flange and control cylinder 1 end be divided into via the large through-hole 201 of the little flange of right draining guiding valve 99 left ends and small through hole 101, source water is discharged the air in control cylinder 1 right chamber and the annular chamber via outlet valve 59, simultaneously, this source water also enters the right paddle hole 62 of piston cylinder 4 in control cylinder 1 right chamber, and the air in the logical 4 hollow minutes chambeies of piston is extruded in the big pumping cylinder, source water is through big pumping cylinder left

side paddle hole

11,7,98,90 enter air that big pumping cylinder left side will be wherein all from left side outlet valve 27,44,58,80 discharge, until above-mentioned each outlet valve 59,27,44,58,80 all during draining, immediately with these several exhaust valve closure; Source water continues each big piston 29,46,67,88 of input promotion and moves to right, will be near before the right dead point, left side elastic limit device 52 moves to right again, begin to push reversing slide valve 55, plan the position that it pushes the restriction piece 61 at right dead point to, but because of control cylinder 1 right chamber is full of the back pressure of source water and the surface friction drag that reversing slide valve 55 Sealings own cause, reversing slide valve 55 can not be moved to right and give left elastic limit device 52 with counter-force, this counter-force makes left elastic limit device 52 produce resiliently deformable and absorption pressure energy, is in the arm-to-arm of the accumulation of energy more that moves to right more.Make when avoiding taking place right elastic limit device 63 right laterals right draining guiding valve 99 and big piston synchronously near right dead point, right draining guiding valve 99 has been opened the right weep hole 65 of part, not work done of source water stops to move to right with regard to release draining, big piston, directly advancing right weep hole 65 after source water enters from control cylinder 1 right water inlet 56 discharges, it is the termination of pumping phenomenon, designed a kind of structural type of unidirectional small damping effect in the utility model, front-seat neatly valve has damping effect in the open row water hole, is closing the front-seat neatly valve of weep hole undamped effect.Now details are as follows in conjunction with the right lateral journey: right draining guiding valve 99 (left bank neatly valve 5 is identical), except that the surface friction drag that Sealing own had, in control cylinder 1 right chamber, little flange is arranged, as previously mentioned, form the right annular chamber of a damping with the end of control cylinder, be full of source water in this chamber, moving to right of right side sluicing guiding valve 99 caused back pressure, large through-hole 201 is arranged on little flange, small through hole 101, when beginning to contact, right elastic limit device and right draining guiding valve 99 promptly block large through-hole 201 gradually, the piston contact pressure that moves to right more is big more, be out of shape big more, all sternly stifled up to distortion and contact pressure large through-hole 201, promote right draining guiding valve again and move to right, the water of right annular chamber must be extruded into the right chamber of control cylinder 1 from only surplus small through hole 101, the small damping phenomenon promptly occurs, the surface friction drag of this damping and Sealing has been postponed moving to right starting time of right draining guiding valve 99, and the right elastic limit device 63 that piston cylinder is driven is obstructed when moving to right.As shown in Figure 6, the pressure weak point that it is y coordinate P that elastic limit device is subjected to resistance, be subjected to produce behind the resistance is deformed into abscissa ψ, the pressure that absorbs can be y coordinate E, the pass of distortion ψ and energy-absorbing E is the non-linear relation, it is not to wait that per stage of promptly being out of shape the ψ overall process absorbs ENERGY E, elastic limit device move the later stage be the draining guiding valve start in earlier stage be subjected to resistance P more large deformation ψ big more then to absorb ENERGY E many more, wherein, be directly proportional with energy-absorbing E by resistance P, i.e. P ∝ E.The characteristic curve that elastic limit device has closes, and is the setting of the flexible characteristic curve relation of cumulative type by the ENERGY E of its resistance P that is subjected to or suction and the relation of distortion ψ.Fig. 5 promptly is a kind of two oblate structural representations that have in the elastic limit device of this characteristic curve relation.Right elastic limit device 63 is more because of the big energy-absorbing E of distortion ψ in the later stage that moves to right, and the initial start that right draining guiding valve is moved to right is very favorable; After the water section of right annular chamber enters the right chamber of control cylinder 1 from small through hole 101, damping has weakened, right draining guiding valve is started up to moving to right fast to acceleration by halted state by right elastic limit device 63 pushings, the power of this pushing is made up of two-part, the one, the power that piston moves to right, the 2nd, right elastic limit device distortion energy-absorbing discharges the power that produces, two power are synthetic by right draining guiding valve is pushed to move to right with speed V2 slowly and soon, along with weakening of damping, the contact pressure that acts on the right elastic limit device reduces and the distortion recovery, make large through-hole 201 beginning water flowings, to the resistance that makes the right draining guiding valve that moves to right is the surface friction drag that only is left Sealing, its speed that moves to right is more accelerated, be that speed V2 is more and more faster, moving on to right dead point rapidly opens right weep hole 65, big piston moment also arrives right dead point with the speed V1 that is slower than V2, meanwhile, big piston 29,46,67, the low-pressure head water of 88 left side works done begins release and begins from big

piston paddle hole

11,7,98,90 enter the branch chamber of piston cylinder 4 rapidly, come out from its right paddle hole 62, entering the right chamber of control cylinder 1 again discharges from right weep hole 65, carrying out along with the left lateral journey, the setting-out that unloads in big piston left side will be by emptying, meanwhile, the pressure that is subjected to during left side elastic limit device 52 right laterals contact reversing slide valve 55, distortion, the energy-absorbing situation, the same in right lateral with right elastic limit device 63, when reversing slide valve 55 is controlled the back pressure releasing in cylinder 1 right chamber, left side elastic limit device 52 accumulation of energys are sufficient, add the move to right power of piston right lateral journey before right dead point again, with very fast speed V3 reversing slide valve is shifted to the right to the position that right dead point promptly restricts piece 61, and control cylinder 1 right water inlet closed, water inlet, a left side is open, and source water begins to enter control cylinder 1 left chamber.Piston is before approaching right dead point in this process, moving to right in the stroke always, and right draining guiding valve moves to right and lags behind starting time, and reversing slide valve starts slightly late and moves to right, so but can arrive right dead point simultaneously because of V3＞V2＞V1 reversing slide valve, right draining guiding valve, big piston.And left bank neatly valve 5 also is shifted to the right to right dead point synchronously under big piston 46 right lateral journey effects, and the left bank water hole 51 of control cylinder 1 is closed, and its little flange and control cylinder 1 left part in control cylinder 1 forms left damping annular chamber equally simultaneously.Source water is the large through-hole 202 on the little flange of left bank neatly valve 5 again through control cylinder 1 left chamber, small through hole 102, enter left annular chamber, through outlet valve 50 emptyings of the air of part from control cylinder 1 left end, simultaneously, source water advances in the piston cylinder branch chamber again to big pumping cylinder 28 from the left paddle hole 3 of piston cylinder 4,45,68, in 82, from big piston 29,46,67, the paddle hole 10 on 88 right sides, 6,97,89 come out, wherein all air outlet valve 30 on the big pumping cylinder right-hand member outside diameter wall, 49,66,81 discharge, same with the right lateral journey, each outlet valve 50,30,49,66, immediately it is closed after the 81 beginning water outlets, source water can continue from 54 water inlets of left water inlet, big piston 29,46,67,88 left lateral journeys also will repeat the overall process of right lateral journey to the left dead point.But, when right draining guiding valve 99 moves to left, because of large through-hole 201, small through hole 101 are all opened simultaneously, so big piston 67 can push over left dead point and the undamped effect with right draining guiding valve 99 synchronously.Draining guiding valve in the left and right sides all has this unidirectional damping effect.After big piston arrives left dead point, begun the right lateral journey again, move back and forth.The little pumping cylinder 24 that with same shaft axis link to each other with big pumping cylinder and big piston this moment, 41,93, small piston 25 in 86,42,94,87 also in company with the synchronous shift to right or left of big piston, when initially opening the pump exhaust, big piston is from a left side (descending) small piston 25 when the dead point moves to right, 42,94,87 right side air is through going out water one-

way valve

12,8,95,91 discharge, right side water inlet one-way valve 26,43,70,85 are in closed condition, the water inlet one-way valve 23 in small piston left side, 31,69,84 is open, tap into the source water of introducing through water pipe 22 by gate valve 83, this moment small piston left side go out water one-

way valve

14,9,96,92 close, when big piston makes left lateral into; the left side of little pumping cylinder goes out water one-way valve 14; 9; 96; 92 begin to export high pressure water; the water inlet one-way valve 23 in left side; 31; 69; 84 close; small piston right side water inlet one-way valve 26; 43; 70; 85 from gate valve 83 through water pipe 22 feed source water, the right side go out water one-way valve 12; 8; 95; 91 close.When big piston begins second right lateral journey again behind left dead point, earlier that gate valve 21,47,57 is open, progressively gate valve 48,53 is slowly turned down but is not related to extremely suitably and dam, during to the 3rd right lateral journey, gate valve 83 can be closed according to operating mode, the part release draining that only utilizes control cylinder 1 to discharge enters each little pumping cylinder, be that release draining 1 route waste pipe 20 is drained, 1 tunnel part enters the water source of little pumping cylinder as the output high pressure water in addition, also have part to drain from the pipe 22 of original do water inlet, but the draining back pressure must not appear, to adapt to the hydropenic operating mode in water source; When the flow of source water is very sufficient gate valve 47,75,21 is closed simultaneously, gate valve 48,53,83 is open simultaneously, and promptly the high pressure water of work done water and output is all used same source water.When the temporary needs termination of pumping, enter in the pump housing for avoiding user's aqueous reflux to outlet pipe 13, when closing intake pipe, also gate valve 15 to be closed.Can on intake pipe 60, install filter cleaner and gate valve additional as needs, not shown in the figures.

The stroke of the reciprocating pump that the utility model is related carries out automatically by design rule, there is source water pressure in left and right minute chamber of control cylinder when the water inlet state, for avoid this pressure with the draining guiding valve freely to big piston one side slip, the draining guiding valve is at the big flange of large size of big pumping cylinder one side, its inboard light face can closely connectedly contact with the light wall of big inboard, pumping cylinder end, the total pressure that this moment, big flange another side was subjected in big pumping cylinder is greater than the suffered total pressure of little flange small size, so the draining guiding valve can free slippage.
