Description
Technical field
The invention belongs to fluid machinery technical field, be specifically related to the interactive plunger displacement pump of a kind of electromagnetic force.
Background technology
For water pump, oil pump and air compressor, conventionally by explosive motor or Motor Drive. Traditional method is: first by explosive motor or motor, rotating machinery power is carried out to machinery dynamical parameters conversion through intermediate link as shaft coupling, belt transmission etc., then through toggle or the swash plate piston shoes mechanism etc. of plunger displacement pump, rotating machinery power is converted to the reciprocating linear machine power of plunger, finally by plunger, its reciprocating linear machine power conversion is output as to fluid dynamic. Patent and the document of this respect are numerous.
Although above-mentioned energy bins assembly system can be output as fluid pressure energy by heat energy or electric energy conversion, but because the connecting rod swing of toggle in system causes that piston side is larger to force rate, not only cause mechanical efficiency loss, heavy wear between piston and casing wall, plunger and casing wall and extra heat load, toggle is subject to force intensity large simultaneously, the frictional dissipation at each pin joint place is serious, and the unevenness of system running is large. Long due to system capacity conversion, transfer route most serious of all, pass through multiple intermediate transfer links, cause conversion transmission efficiency low, energy dissipation is serious, system complex, heaviness, the problem such as production cost and operating cost are high, seriously polluted.
Between free-piston engine, Hydraulic confined piston engine, cylinder, gear coupled engine, electromagnetic pump etc. can both overcome the drawback of aforementioned system, be directly fluid pressure energy by fuel combustion heat energy or electric energy conversion, transfer route is short, energy efficiency is high, and the document of this respect and patent are also very abundant. They and this patent belong to plunger displacement pump together, wherein, between cylinder, gear linked hydraulic engine and structure of the present invention are the most close, all two plungers, between plunger, pass through gear-linked, but its power cavity is combustion chamber, the gaseous-pressure that fuel combustion produces promotes piston-plunger assembly and moves the fluid pressure energy the instant output that the heat energy of this cylinder fuel burning generation are converted into this cylinder, there are the fuel feeding system of conventional engines, cooling row, lube system, intake and exhaust system, valve actuating mechanism, toggle etc., complex structure; The function of its linkage gear is that the portion of energy of left cylinder expansion stroke is delivered in flywheel and is stored, and releases energy and is delivered to left cylinder by linkage gear again, for the corresponding stroke of left cylinder provides energy at other stroke flywheel.
The power cavity of electromagnetic pump is linear electric motors or solenoid, and the former controls complexity, and technology is ripe not enough, is used less, so be mainly the latter. Solenoid when energising become there is the N utmost point, the electromagnet of the S utmost point. One permanent magnet is set conventionally on plunger, makes its polarity contrary with solenoid, while energising solenoid promote plunger away from, plunger pumps liquid; And a return spring is set, when power-off, spring promotes plunger return and sucks liquid. What also have does not arrange permanent magnet, like this when solenoid energising, magnetizes and attracts plunger to approach, and plunger pumps liquid; And a return spring is set, when power-off, spring promotes plunger return and sucks liquid. Above-mentioned electromagnetic pump, the former has again spring by existing permanent magnet, and loosely organized heaviness, is not easy to installation and maintenance, and cost is high; The latter's pump body structure is arranged the physical dimension that is seriously limited to solenoid, also has return spring simultaneously, causes that efficiency is low, radial dimension is large. When the work of above-mentioned electromagnetic pump single cylinder, the inertia that plunger moves back and forth is difficult to balance in addition, and operational vibration is violent, noise is large, unstable; When multi-cylinder collaborative work, the interlock control of each cylinder plug is comparatively complicated again.
Summary of the invention
