Description
The utility model relates to fluid pressure energy regenerative apparatus, relates in particular to straight moving piston-type hydro pressure infusion set, is called for short Directacting transfusion system.
Chemical reaction in petrochemical iy produced, mass transport process etc., existing in a large number can be for the pressure energy that reclaims.Produce such as middle-size and small-size ammonia factory: 32MP is arranged
aLiquefied ammonia, 12MP
aCuprammonia, alkali lye, 20MP
aUrea liquid etc. must reduced pressure storage, circulation, regeneration or flash distillation are used, owing to carried a large amount of solids, gas impurities secretly in the liquid, penetrablility is strong and flow discontinuously, and inflammable and explosive again corrosive property is strong, and therefore, pressure is can recovery technology quite complicated.So far, both at home and abroad the recoverable hydraulic machine of working pressure has: 1. hydraulic turbine, and it is not suitable for the high pressure low discharge, and efficient is lower; 2. water turbine, it is especially big only to be suitable for flow, and the very low occasion of pressure can't be used; 3. HM Hydraulic Motor, it is unsuitable for gas, solid impurity, the inflammable and explosive petrochemical complex liquid that corrosion is arranged; 4. jet dredge pump can only be suitable for liquid-liquid and mix situation, and efficient is extremely low; 5. directly moving biserial piston type energy reclaims machine, and the total system bulky complex from introducing so far in the early days of foundation, can't be applied; 6. rotary piston energy-recovering machine, promptly utility model " piston Hydraulic Energy Recovering Machine " has piston crank mechanism, compare with 5, volume is little, system is simple, but the machine rotational speed height, structure is complicated; 7. free-piston type energy-recovering machine, promptly utility model " overbottom pressure power piston formula Hydraulic Pump " and 5,6 is compared, and is improved, and has now produced examination more than 3000 hour, and is very promising, but also exists some key technical problems to overcome; 8. floating piston energy-recovering machine, i.e. " floating piston type liquid transporter " compared with above-mentioned, and bigger improvement is then arranged, but can only be applicable to some specific occasion, and must make biserial, makes flow even.
The purpose of this utility model provides a kind of simple in structure, Directacting transfusion system that efficient is high, safe and reliable.
The utility model is taked following measures in order to achieve the above object: it comprises fluid power cylinder and liquid dispensing apparatus two parts; Liquid dispensing apparatus has priority valve and main valve, and they are cylindrical reversing slide valve; Priority valve has guide's spool, guide's valve body, fills out letter, push rod, slide block, push rod; Main valve has two, and they have main valve plug and main valve body respectively; Push rod, slide block, push rod pass to guide's spool with piston motion to the information of dead-centre position.
Advantage of the present utility model because pump adopts reversing slide valve suction liquid, thereby when having avoided piston stop return, the valve of spring non-return valve hit with cylinder in water attack, improve crank motion speed greatly.Because piston commutation signal lead-out mode changes, thereby take public cylinder cap and must not fill out the bigger axial distance that shortened of letter.So compared with the prior art have crank motion speed height, simple in structure, volume is little, in light weight, vibrating noise is little, advantage such as of many uses.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is the Directacting transfusion system structural representation.
Directacting transfusion system comprises fluid power cylinder and liquid dispensing apparatus two parts, and fluid power cylinder is by two identical cylinder diameter cylinder bodies, that is two single pumps 7 and Hydraulic engine 13 are composed in series; The public cylinder cap of two cylinder bodies, piston rod 5 runs through public cylinder cap, and 4 series connection of two pistons are tightened to one, and is reciprocating in cylinder.Liquid dispensing apparatus has priority valve and main valve, and they are cylindrical reversing slide valve; Priority valve has guide's spool 8, guide's valve body 9, fills out letter 10, push rod 12, slide block 14, push rod 3; Main valve has two, and they have main valve plug 1,15 and main valve body 2,16 respectively; Push rod, slide block, push rod pass to guide's spool with piston motion to the information of dead-centre position.Two main valves are parallel connection separately or series connection, and two main valves also can be head and the tail series connection or head and the tail parallel connection, distribute the dual-use function combination valve thereby constitute the liquid with Hydraulic engine and pump.Directacting transfusion system is horizontal, also can be vertical.When piston moves near dead-centre position, run into push rod, slide block slided act on guide's spool, but also can adopt electromagnetic valve, by electromagnetic force act on priority valve, controlling liquid commutation when making dead-center position of piston.
The utility model principle of work is as follows: during as shown for the nonoculture cylinder, piston is separated into two chambeies with a cylinder body, and a side cylinder chamber of fastening piston rod is a pump, and piston opposite side piston-rodless cylinder chamber then is a Hydraulic engine; Because piston rod has accounted for a part of piston area, though so be lower than high pressure using system entrance pressure slightly from the pressure of high pressure using system 11 outlets, start on the pusher side piston area power still greater than pump side power but act on, therefore can promote piston reciprocates, the pump work done.When piston moves to dead-centre position left, piston is run into push rod 3, makes framework, and promptly slide block 14 slides left, promote priority valve push rod 12, pilot valve core 8 is moved to the left, and high pressure liquid body opening P and hole A are communicated with, and low pressure liquid hole O and hole B are communicated with, so controlling liquid commutation, highly pressurised liquid flows to the right chamber of two valve body of main valve 16,2 through PA, and corresponding promotion valve core of main valve 15 and 1 is moved to the left, and therefore makes two main valve respective aperture P
1A
1, be communicated with the outlet of high pressure using system, P
2A
2Be communicated with the import of high pressure using system, and B
1O
1Hole B
2O
2The hole is by drilling through the import and export that the hole is communicated with low pressure disposal system 6 respectively in the middle of the main valve plug; Meanwhile, the liquid in chamber, a valve body of main valve left side enters the low pressure disposal system through priority valve BO hole.Therefore from the highly pressurised liquid of high pressure using system through main valve hole P
1A
1Flow into Hydraulic engine cylinder 13 left chambeies, promote piston and move right,, thereupon, the right chamber of engine cylinder liquid is passed through hole B liquid work done in the pumping cylinder 7
1Drill through hole and hole O in the middle of the main valve plug
1Unload and be depressed into the low-pressure system processing, meanwhile, liquid is subjected to moving right the compression of piston in the pumping cylinder 7, and pressure improves, through main valve A
2P
2The hole is pressed into the high pressure using system, and low pressure disposal system liquid is through O thereupon
2B
2Suck the right chamber of pumping cylinder.So driven plunger constantly moves right, and in the time of will closing on right dead-centre position, again in the opposite direction, in like manner repeats said process, and the piston return is to left movement.Make ceaselessly reciprocatingly like this, reclaimed the waste liq pressure energy of having finished the chemical process effect from high pressure using system outlet, the fresh liquid of having handled in the pump is transported in the high pressure using system goes.The outlet of low pressure disposal system also has electronic high pressure pump (not drawing among the figure), and a part of low pressure liquid is transported to the import of high pressure using system, makes whole flow process obtain energy and flow equilibrium, constantly running.
