The circuit diagram of Fig. 3, the utility model electromagnetism diesel oil oil transfer pump.
Embodiment
As shown in Figure 1, electromagnetism diesel oil oil transfer pump of the present utility model mainly by inlet space 1, the pump housing 2, go out grease chamber 3, electric control room 4 constitutes, inlet space 1 is connected with oil circuit by pipe joint 5, and be connected the lower end of the pump housing 2 by bolt 6, the pump housing 2 upper ends pick out grease chamber 3, tightly plug with molten metal with electric control room 4 and be connected by going out grease chamber 3 again, go out grease chamber 3 and be connected with outer oil circuit by pipe joint 7.Its middle pump body 2 mainly is made up of shell 21, coil 22, spring 29, cylinder sleeve 23, plunger 24 etc., and wherein cylinder sleeve 23 is plugged on support 25 endoporus of coil 22, and cylinder sleeve 23 is copper cylinder sleeves, and lower end and oil-feed 25 is connected, and is used to separate coil and oil circuit.As shown in Figure 2, oil-feed 25 is conical surface hole shaft types, fixing by outer lug boss 51 with the shell welding of the pump housing 2, corresponding with the end that cylinder sleeve 23 cooperates with the plunger 26 that is positioned at cylinder sleeve, its opposing side 52 is conical surfaces, strengthened the suction-combining force, can in releasing course, improve release performance greatly again plunger 24; Oil-feed 25 the other end have been installed one-way valve 27 and have tightly been pluged with molten metal by back-up ring 28 in the hole.Inlet space 1, go out grease chamber 3 and cooperate, form the oil circuit of a sealing with cylinder sleeve 23.Between oil-feed 25 and the plunger 24 supported spring 29 is arranged, there is the one-way valve 30 that leads to grease chamber 3 plunger 24 upper ends, and lower end and oil-feed 25 is corresponding, and its opposing side is the conical surface.Coil 22 has two groups, and two ends are by oil resistant rubber pad 11,13 and 12 sealings of " O " type circle up and down.Triode 33 is installed in out top in the grease chamber 3, and support 32 is spacing when plunger 24 rises, and arrives electric control room 4 by wire connecting hole 34, is connected with its impulse circuit base plate 41, is connected with circuit by the wiring terminal 42 on the electric cover cap 42 again, forms impulse circuit; Go out between grease chamber 3 and the electric control room 4 and tightly plug with molten metal by bolt.Its circuit diagram as shown in Figure 3, electric current is in the moment of conducting, electric current directly arrives the b utmost point of triode Q, makes the triode Q degree of depth saturated, conducting main winding L
1Produce electromagnetic attraction, make the plunger adhesive; On state: electric current provides a bias voltage loop through b, the e utmost point of biasing resistor R to triode Q, arrives actuating coil L through the c utmost point, the e utmost point
2Back ground connection, the adhesive of control pump; Cut-off state: it is saturated later because the conducting electric current no longer rises in value the work winding L that triode Q enters the degree of depth
2Produce reverse potential, the feedback winding L
1Produce induced potential, triode Q ends, and plunger discharges.Main winding reverse induction electromotive force forms discharge loop by the b utmost point of ground, diode D, triode Q, and progressively discharge is carried out, and the b pole tension of triode Q raises, when reaching the triode conducting voltage, and triode Q conducting main winding L
1: voltage---the c utmost point---e utmost point---actuating coil L
2---ground, so go round and begin again, make plunger upward and downward, finish pump oil working procedure.
This oil transfer pump has been owing to adopted the control of electric impulse circuit, utilizes electromagnetic performance to make plunger to-and-fro motion in cylinder sleeve, thereby finishes the work of pump oil, replaced manual pump oil, and is easy to use, and reliable performance.
