Description
Technical field
The present invention relates to a kind of novel driving clutch self-priming apparatus, especially a kind ofly drive centrifugal pump and vacuum pumping device by a motor simultaneously, automatically can completing without the need to automatical control system the self-priming apparatus that medium puts on, using mainly for putting on operating mode under dielectric fluid.
Background technique
Constantly perfect along with self-priming pump technology, its Security, stability are more and more higher, and the application area that operating mode put on by self-priming pump under dielectric fluid is more and more wider.Original common self-priming pump is equal to 1, suction lift lower (1-4 rice); 2, self-priming time longer (5 minutes even longer); 3, self-priming reliability is not strong, does not often inhale medium; 4, need stream be returned for realizing self-absorption function, thus make pump efficiency low; 5, north of china in winter outdoor is not suitable for; 6, interior return port often blocks, and fault multidimensional is repaiied the problem such as frequent and progressively exited self-priming pump market.Self-priming pump (the additional self-priming apparatus of centrifugal pump and automatical control system) in the market also exists: 1, preparation is many, complex structure.2, electrical apparatus element are fragile, cause pump can not normal self-priming.3, cost high, 4, there is no the problems such as power supply then cannot use.Compare these self-priming pumps " a machine biobelt self-priming pump " patent No.: ZL 201420082035.X and " a kind of Novel chemical self-priming pump " patent No.: ZL 201420082037.9 overcomes the shortcoming of above-mentioned self-priming pump, have: 1, compared with Self-priming pump, self-priming apparatus and centrifugal pump are driven by a motor or diesel engine, without the need to electric control system, overall structure is more simply compact, cost is lower, stable performance, failure rate is low; 2, self-priming time is short, and ability is strong, and maximum suction lift can reach 7 meters; 3, medium is not deposited in self-priming pump case, pipeline, resistance to frost is good, be applicable to the advantages such as north of china in winter use, but also exist: 1, vacuum pumping device overall length is larger, heavier-weight, be directly installed on motor or centrifugal pump shaft, Standard centrifugal pump or motor changed comparatively large, be unfavorable for the production in enormous quantities of pump and the after-sales service of motor; 2, it can have certain influence to pump and whole motor structure and axle intensity to the variation of motor and pump structure; 3, because motor shaft is different with pump shaft of centrifugal pump specification, its live axle diameter of axle alters a great deal, and vacuum pumping device or belt pulley are directly installed on live axle, and the diameter of axle must adapt with pump or the motor diameter of axle, is unfavorable for standardized designs and the production of vacuum pumping device; 4, the problem such as not to be approved at by this kind of drive certain customers of belt transmission.
Summary of the invention
thisthe object of invention is the deficiency for existing in above-mentioned technology, provides a kind of driving clutch self-priming apparatus novel reliably.Self-priming apparatus and centrifugal pump are driven by a motor or diesel engine, and without the need to electric control system, overall structure is more simply compact, and cost is lower, stable performance, failure rate is low.
The object of the present invention is achieved like this: comprise centrifugal pump, dual-axle motor, vacuum pumping device and clutch four part.It is characterized in that, adopt dual-axle motor, respectively there is an axle motor rear and front end, front axle is connected with centrifugal pump, rear axle is connected by clutch with vacuum pumping device, and outlet of centrifugal pump is provided with outlet connecting pipe part, and outlet connecting pipe part is connected with outlet self-priming valve and clutch separate lines, clutch separate lines connects clutch release assembly, and clutch release assembly is connected with clutch.
Start dual-axle motor during work, clutch closes, and centrifugal pump and vacuum pumping device operate under motor antero posterior axis drives simultaneously, now gassy in centrifugal pump, and centrifugal pump dallies, and vacuum pumping device to extract in centrifugal pump and suction line gas to centrifugal pump pump priming.When in pump, gas is evacuated, when medium arrives outlet connecting pipe part, the lower pontoon assembly of outlet self-priming valve floats by medium floating function and closes, vacuum pumping device is inhaled into stop medium, close not in time for preventing lower pontoon assembly, medium enters vacuum pumping device and is discharged to working site and pollutes, and on lower pontoon assembly increases, float component carries out secondary Drain Resistance.While outlet self-priming valve is closed, outlet of centrifugal pump medium enters clutch release assembly from clutch separate lines, drive clutch release assembly draw-in bar to pull clutch shifter to make throw-out-of clutch, vacuum pumping device stops vacuumizing, and centrifugal pump starts to run well.For after the termination of pumping of guarantee centrifugal pump, medium is thoroughly emptying, suction line or centrifugal pump establish suction valve and drain line, suction valve air inlet after centrifugal pump termination of pumping, in centrifugal pump, liquid level declines, in centrifugal pump, residual medium flows back to suction line, reclaim line from drain line or is directly discharged to the external world, ensure that in centrifugal pump, medium is thoroughly emptying.For improving the automaticity of device further, avoid because operator has an accident in inflammable and explosive occasion operation as far as possible, outlet valve and outlet valve membrane separation wheel cylinder is established at pump discharge, when vacuumizing, pump discharge is negative pressure, outlet valve is closed under spring force, and after pump production run, pump discharge pressure promotes outlet valve membrane separation wheel cylinder, pull lever overcomes spring force and opens outlet valve, realizes the automatic opening and closing of outlet valve.According to concrete operating mode, vacuum pumping device can adopt: the various ways such as diaphragm type vacuum pumping device, air ring type vacuum pump, Roots pump.
Beneficial effect of the present invention: 1, main pump adopts centrifugal pump, it is simple that centrifugal pump has structure compared with other pumps, transfusion pulsating movement free, and Flow-rate adjustment is simple, the advantages such as operating range is wide, for all pump-type are first-selected; 2, motor adopts dual-axle motor, and motor rear portion leans out an axle and connects clutch, and drive vacuum pumping device to vacuumize, compact structure, clutch length is short, better stressed compared with whole assembling to motor rear portion; 3, clutch diaphragm separation master cylinder is separated with clutch diaphragm between wheel cylinder and adopts hydraulic line to connect, be separated wheel cylinder by clutch diaphragm and pull pull bar holdback clutch, avoid being separated master cylinder direct pull pull bar by clutch diaphragm, the problem generation that the oversize intensity of pull bar is bad, reliably convenient; 4, energy self-priming, without the need to manual pump priming, starting time is short; 5, eliminate electric control system, control unit is more simple and reliable; 6, during vacuum pumping device running, centrifugal pump idle running is not done work, and after centrifugal pump production run, vacuum pumping device and motor are thrown off, and no longer consumes motor electric energy, and two equipment share a motor, both without expanded motor power, can save again a motor; 7, vacuum pumping device can adopt the various ways such as diaphragm type vacuum pumping device, gas ring vacuum pump, Roots pump, is applicable to the different operating mode such as large discharge, poisonous and harmful.8, vacuum pumping device is driven by electric motor back shaft, and this diameter of axle and other spot sizes are without interference, and the rear axle of all specification motors is same size, and centrifugal pump does not need to change, and is standard pump-type, facilitates standardized designs and the production of centrifugal pump and vacuum pumping device; 9, outlet valve is by hydraulic control, automatically opens and closedown, and alleviate the labor intensity of operator, Security is higher.
