Abstract
A kind of be furnished with the power-actuated high-pressure plunger pump of numerical control, by including conventional fluid power part that cylinder body, cylinder sleeve, plunger, feed liquor valve, liquid discharging valve form and by programmable controller, the electromechanical integration new product that the numerical control motivational drive that variable ratio frequency changer inverter, numerical control rare-earth synchronous motor and cycloid in planet retarder are formed partly constitutes.By the tooth bar to-and-fro motion of inlaying on the gear drive plunger rod on the reducer output shaft, promote plunger and in cylinder sleeve, inhale press liquid, cast off traditional gearing once and for all, make plunger stroke leap ahead greatly, discharge opeing pressure, flow be stable and controllable all, can elongated component working life, improve volumetric efficiency.
Description
The present invention relates to a kind of hydraulic energy source equipment of new structure, exactly, relate to a kind of power-actuated high-pressure plunger pump of numerical control of being furnished with.
Plunger pump and gear pump, vane pump are compared, because the plunger of plunger pump is that the garden post cooperates with cylinder bore, obtain higher quality of fit easily and sealing improves greatly, and therefore, plunger pump can bear higher pressure and higher volumetric efficiency is arranged.It can obtain bigger flow, and suction capacity is strong, and flow is regulated easily.So plunger pump is widely used in the hydraulic system of oil, metallurgy, machinery (as broaching machine, double column planing machine, running mechanism), still, traditional high-pressure plunger pump drive mechanism complexity, easily damaged parts are many, the volume heaviness.Because adopt crank-connecting rod that rotatablely moving of power system changed into the straight line motion repeatedly of plunger, so the straight line motion that obtains also is sinusoidal rule to be changed, the lifting rate of single plunger pump is that sinusoidal rule changes equally, causes the fluctuation of delivery pressure.The wave phenomenon of this pressure transient can cause a series of hydraulic machinery and use the trouble of process aspect of object and passive.
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, driving mechanism is simple, infusion pressure and stability of flow, and improve its operating conditions be furnished with the power-actuated high-pressure plunger pump of numerical control.
Structure of the present invention as shown in Figure 1, it is to include by cylinder body 1, cylinder sleeve 2, plunger 3, feed liquor valve 11, fluid power part and electric drive that liquid discharging valve 12 is formed are dimerous, it is characterized in that studding with on the plunger rod 4 tooth bar 4A, this tooth bar is reciprocating and driven by the gear 6 that is meshed with it along guide roller 5, gear 6 is contained in by on the output shaft of numerical control rare-earth synchronous motor 8 for the cycloid in planet retarder 7 of power, and numerical-control motor 8 is connected to the variable ratio frequency changer inverter 9 of its control with to the variable ratio frequency changer inverter and controls and and the shared programmable controller 10 of other devices.
The present invention is to be the electronic information technology transformation traditional mechanical product of core with contemporary microelectronic technology, the example of realization electromechanical integration.It mainly be use can comprehensive real-time numerical control electric drive for driving, the result that the power section and the drive part of former plunger pump are transformed.This fully numerical-controlled electric towing (number of patent application CN92100001.4) is by the microcomputer of systems management maincenter (programmable controller) output speed to motor, rotation acceleration, turn to, moment of torsion, stroke need and carry out real-time digital control according to the optimization of real-time working condition, thereby do not need conventional, huge and complicated transmission system converts motive rotatablely moving the to-and-fro motion of plunger to, like this, can cast off traditional gearing once and for all: crank-connecting rod, crosshead, mechanisms such as cross-head guide mechanism are parts in addition, make the moving direction of plunger, various movement elements such as speed are fully by the various information datas of microcomputer to production process, carry out in good time collection, analyze, handle, transmission, after the utilization, the instruction of sending is controlled in real time, like this, can guarantee draining flow of the present invention, the pressure bistable, eliminate the sinusoidal regular fluctuation that connecting rod causes fully, in entire work process, realize optimizing controlled state all the time.And, cancelled the restriction of crank-connecting rod, the stroke of plunger can be realized increasing considerably according to arts demand, like this, improved the operating conditions of pump again greatly, can effectively prolong the working life of oil pump, plunger, valve, the volumetric efficiency of pump is further enhanced.
Fluid power part of the present invention is the same substantially with traditional plunger pump or reciprocating pump: working solution flows into from import 13, enter cylinder body by feed liquor valve 11, cause that by plunger 3 is reciprocating in cylinder sleeve 2 liquid capacity changes in the cylinder, with liquid by back pressurization in feed liquor valve 11 suction cylinders again outside liquid discharging valve 12 and outlet 14 excavationg pumps, working principle is consistent with the reciprocating pump of routine.Its drive part also is foolproof: stud with tooth bar 4A on the plunger rod 4 of plunger 3 rear ends, this tooth bar can reciprocatingly slide along its guide roller 5, and is meshed with gear 6 and is driven by it.Gear 6 can drive a tooth bar, constitutes unidirectional plunger pump, also can drive two tooth bars simultaneously, makes it to do synchronous incorgruous to-and-fro motion and constitutes bidirectional ram pump.Gear 6 is contained on the output shaft of cycloid in planet retarder 7, is rotated by numerical control rare-earth synchronous motor 8 driven gear 6 after cycloid in planet retarder 7 slows down.Cycloid in planet retarder reduction speed ratio is big, efficient is high, volume is little; Also can adopt can forward and reverse rotation other retarders, the effect of just working is not as the former.Numerical control rare-earth synchronous motor 8 is by variable ratio frequency changer inverter 9 and programmable controller 10 its runnings of control.And this be by the user of pump according to behaviour in service and the real-time command of sending after requiring after weaving the real-time control working procedure of plunger pump on the PC to send into programmable controller by RS 232C serial communication interface operate.If desired, also can be the output parameter of pump and flow process parameter, and the sensor of monitoring these parameters also connects with programmable controller, makes pump can gather these parameters in real time, control in real time with reference to preferred duty parameter, make the present invention become the high-pressure plunger pump of variable working condition operation.
The present invention can replace various high pressure reciprocating pumps, comprises single effect plunger pump and beidirectional plunger pump, is particularly useful for replacing slurry pump, cementing truck pump, fracturing unit truck pump in the petroleum industry system.With the slurry pump is example, adopt the present invention after, weight is reduced to by original 20 tons be no more than 10 tons, and, possess aforesaid all advantage among the present invention.
