Description

Film drives frequency conversion measuring apparatus
Technical field
The utility model relates to a kind of frequency conversion measuring apparatus, and particularly a kind of film drives frequency conversion measuring apparatus.
Background technique
At present, each gathering station of oil field is mostly plunger pump for delivery of the metering pump of auxiliary agent, and spoilage is high, and maintenance is frequent.The Flow-rate adjustment of pump is to realize by changing the stroke of plunger, and the seal failure of plunger and complicated mechanic adjustment unit are the main causes that causes metering pump to damage.The more general metering pump of application is cammingly and N oblique crank Z plunger type now.During the left stroke of cammingly single-action plunger piston metering pump, cam promotes plunger advancement; During right stroke, plunger moves after under spring action, and the position of moving after plunger is regulated by stroke adjustable lever, plays adjust flux effect.During work, between cam and plunger, there is sliding friction, quick abrasion, the life-span is short; During right stroke, plunger is promoted by spring, and motor is inoperative, therefore power consumption is large, self-suction is poor, is generally used for small flow occasion.N shape bent axle and the stroke adjuster of N oblique crank Z plunger metering pump, for regulating the throw of eccentric of crankshaft-link rod, reach the object that changes plunger stroke and adjust flux.But too small when adjust flux, when throw of eccentric goes to zero, easily cause bent axle stuck, burn motor.During due to adjust flux, require N shape bent axle with motor, to rotate on one side and move up and down on one side, so its stroke adjuster is more complicated, and the difficult processing of N shape bent axle, fragile.If metering pump is with low discharge work, motor is substantially in idling conditions, and efficiency reduces greatly, and energy dissipation is serious.The plunger of above two kinds of metering pumps adopts packing seal.Filler quick abrasion, changes difficulty, leaks serious.The to-and-fro motion on same axis due to plunger and connecting rod, leaking medium easily enters crankcase, and pollution lubricating oil, makes gear lubrication environmental deterioration, and parts are corroded, and shorten working life.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of film to drive frequency conversion measuring apparatus.
Its technological scheme is: comprise motor, worm and gear, eccentric wheel, connecting rod, pilot spool, one-way valve, plunger diaphragm, safety valve, plunger pump, housing, the vertical fixed turbine worm screw of enclosure interior, the two ends up and down of turbine and worm connect by bearing, motor connects turbine and worm by coupling, fixed eccentric on turbine and worm, one end non-movable piston pump of housing, plunger pump comprises circular pump chamber, long strip guiding cavity and pump head, the joint non-movable piston diaphragm of circular pump chamber and pump head, described plunger diaphragm is divided into circular pump chamber the chamber of two sealings, the inside of guiding cavity is provided with pilot spool, wherein one end of plunger diaphragm connects connecting rod by pilot spool, described connecting rod connecting eccentric wheel, the top of described circular pump chamber connects one-way valve.
Above-mentioned plunger diaphragm is comprised of fixed end, basic unit, teflon protective layer, sandwich steel mesh; the outside of plunger diaphragm is fixed end; the centre of plunger diaphragm is sandwich steel mesh, and the outside of sandwich steel mesh is teflon protective layer, and the outside of teflon protective layer is basic unit.
Connection safety valve on above-mentioned plunger pump.
The beneficial effects of the utility model are: by regulating motor speed to change the flow that plunger jig frequency regulates pump; Power end adopts the basic structure of fixed stroke plunger pump, has saved stroke adjuster; Fluid end adopts direct drive diaphragm, directly promotes diaphragm work by plunger, does not re-use working solution and compensation device thereof, without sealed plunger, has solved seal failure and the leakage problem of plunger.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of plunger pump;
Accompanying drawing 3 is structural representations of plunger diaphragm;
In upper figure: motor 1, worm and gear 2, eccentric wheel 3, connecting rod 4, pilot spool 5, one-way valve 6, plunger diaphragm 7, safety valve 8, plunger pump 9, housing 10, fixed end 7.1, basic unit 7.2, teflon protective layer 7.3, sandwich steel mesh 7.4, circular pump chamber 9.1, guiding cavity 9.2, pump head 9.3.
Embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises motor 1, worm and gear 2, eccentric wheel 3, connecting rod 4, pilot spool 5, one-way valve 6, plunger diaphragm 7, safety valve 8, plunger pump 9, housing 10, housing 10 internal vertical fixed turbine worm screws 2, the two ends up and down of turbine and worm 2 connect by bearing, motor 1 connects turbine and worm 2 by coupling, on turbine and worm 2, fixed eccentric 3, one end non-movable piston pump 9 of housing 10, plunger pump 9 comprises circular pump chamber 9.1, long strip guiding cavity 9.2 and pump head 9.3, the joint non-movable piston diaphragm 7 of circular pump chamber and pump head, described plunger diaphragm 7 is divided into circular pump chamber 9.1 chamber of two sealings, the inside of guiding cavity 9.2 is provided with pilot spool 5, wherein one end of plunger diaphragm 7 connects connecting rod 4 by pilot spool 5, described connecting rod 4 connecting eccentric wheels 3, the top of described circular pump chamber 9.1 connects one-way valve 6.
Plunger diaphragm 7 is wherein comprised of fixed end 7.1, basic unit 7.2, teflon protective layer 7.3, sandwich steel mesh 7.4; the outside of plunger diaphragm 7 is fixed end 7.1; the centre of plunger diaphragm 7 is sandwich steel mesh 7.4; the outside of sandwich steel mesh 7.4 is teflon protective layer 7.3, and the outside of teflon protective layer 7.3 is basic unit 7.2.
Connection safety valve 8 on plunger pump 9 wherein.
Owing to adopting fixed eccentric, pilot spool stroke is constant.When motor drives worm and gear to rotate by coupling, fixed eccentric rotates, and connecting rod and pilot spool drive plunger diaphragm to move left and right.During left stroke, pilot spool makes diaphragm projection left, and pump chamber diminishes, and is transferred fluid pressure and raises, and backs down outlet one-way valve and discharges; During right stroke, plunger makes diaphragm projection to the right, and it is large that pump chamber becomes, and is negative pressure state, is transferred liquid and backs down import one-way valve, enters pump chamber.During the work of plunger diaphragm, the pressure of both sides is different, and diaphragm relies on self-force effect to drive and is transferred liquid.When metering pump flow must change, need only regulate frequency-variable controller, change power supply frequency, by changing motor speed and pilot spool jig frequency, reach the object of adjust flux.
