Embodiment
Below in conjunction with Figure of description, describe specific embodiment of the utility model in detail.
Electromagnetic diaphragm metering pump shown in Figure 1, comprise pump head 17 and be mated the power end housing 1 of connection, power end housing 1 comprises fluid end connecting base 26, coil rubber base 28, base 29, coil rubber base 28 two ends are connected with fluid end connecting base 26, base 29 respectively, and base 29 right sides are provided with control panel 30.The pitman shaft 7 that end bolt connects barrier film 16 is set in the said power end housing 1, barrier film 16 right sides are provided with barrier film and adjust cushion rubber 14, pitman shaft about 7 is provided with and hits iron 13, armature 6, hit between iron 13 and the pitman shaft 7 and be slidingly matched by composite bearing 11, armature 6 and pitman shaft 7 secure fit, the end face that hits iron 13 close armature 6 is provided with 0 type damping ring 10, with hit iron 13, armature 6 cooperation positions are provided with coil 27, coil 27 and coil rack 8, yoke cover 12 cooperates to be installed, be equipped with circuit board 32 and connected potentiometer knob 31 on power end housing 1 right side wall, thereby, in the coil 27 during the input pulse electric current, can make armature 6 and hit between the iron 13 electromagnetic force that produces adhesive or repulsion, these electromagnetic force drive link axle 7 left and right sides reciprocal axial motions, thereby driving barrier film 16 moves reciprocatingly, armature 6 with hit iron 13 abutting end surfaces and be provided with antifreeze plate 9, during coil 27 outages, this antifreeze plate 9 is used for the isolated iron 13 that hits, remaining electromagnetic force between the armature 6, this coil 27 and circuit board 32, potentiometer knob 31 matches, potentiometer knob 31 is regulated barrier film 16 reciprocating speed by regulating power frequency, physical circuit belongs to general known technology, repeats no more.Pitman shaft 7 is provided with the Returnning spring 5 of restoring board 4 and corresponding cooperation, and when coil 27 outages, these Returnning spring 5 application of force drive link axles 7 reset.The adjusting gear bar 2 that is provided with adjusting screw rod 3 and is mated with pitman shaft 7 corresponding positions in power end housing 1 right-side cavity, adjusting gear bar 2 is connected with adjusting knob 33, can drive adjusting gear bar 2 by adjusting knob 33 and drive adjusting screw rods 3 and advance or retreat, thus the stroke distances of regulating pitman shaft 7.Described pump head 17 comprises valve block 18, on the valve block 18, following two ends are respectively equipped with inlet valve seat 25, water outlet valve seat 15, be provided with in the inlet valve seat 25 by the ball valve housing 22 that matches, valve ball 23, the one-way valve group that ball valve seat 21 constitutes, ball valve seat 21 bottoms are provided with pad 24, inlet valve seat 25 upper ends are provided with valve gap 20, the end face connecting part of the end face of inlet valve seat 25 and valve block 15 is provided with seal washer 19, both are threaded, water outlet valve seat 15 internal structures are similar to inlet valve seat 25 internal structures, the internal structure principle of described pump head is general known technology, repeats no more.
Described Electromagnetic diaphragm metering pump working principle is as follows: no matter in operation or halted state, all can change the length of stroke of pitman shaft 7 and pass through the stroke speed that regulator potentiometer knob 31 is regulated pitman shafts 7 by adjusting knob 33.Under coil 27 "on" positions, and coil 27 is in the same way around hitting iron 13 and armature 6, hits to produce the electromagnetism the suction-combining force between iron 13 and the armature 6, makes armature 6 and connected pitman shaft 7 travel forward, and compression reseting spring 5; When current potential was zero, above-mentioned electromagnetic force disappeared, and under the restoring force effect of Returnning spring 5, restoring board 4 moves backward together with armature 6 and pitman shaft 7.Because the characteristic of impulsive current, potential value be constantly by zero cyclically-varying to non-zero, thereby impel pitman shaft 7 to do linear reciprocating motion, and then drive barrier film 16 and work.When barrier film 16 begins to move right, induction stroke begins, pump head 17 internal pressures reduce, when pump head 17 internal pressures are lower than inlet ductwork pressure, the suction port one-way valve is upwards pushed open, and medium is inhaled in the pump head, equates until pump head internal pressure and inlet ductwork pressure, at this moment, the one-way valve of suction line resets.When barrier film 16 began to travel forward, discharge stroke began, and the pump head internal pressure begins to raise, when the pump head internal pressure was higher than export pipeline pressure, the exhaust port one-way valve was upwards pushed open, and medium is discharged from pump head, equate that with discharge conduit pressure the outlet one-way valve resets until the pump head internal pressure.And then enter next circulation.
