CN2041731U - Full-wave electromagnetic pump - Google Patents

Abstract

The utility model relates to a full-wave electromagnetic pump, which directly uses single-phase or three-phase full-wave electric voltage transmit magnetic force to complete the alternating motion of a piston and the opening and closing of a valve, and liquid or air is pumped and extruded. The pump has the advantages of low cost, saving electric force, not disturbing power source, high water out pressure, saving metallic material, tiny volume and simple preparing process, etc., and the utility model is easy to be made into the products of explosion proof, damp proof and corrosion protection.

Description

Full-wave electromagnetic pump

The single-phase half-wave pulse electromagnetic pump that present city uses, its structure is that the garden is wound with one group of coil outside a nonmagnetic metal pipe, diode power source of coil tandem, coil two ends are the electromagnet poles that constitute with electrician's soft iron, and the pipe inner end is placed with soft iron siphunculus--the piston of a band one-way valve.After piston has been responded to the magnetic field of one group of coil (half cycle of Ac) during work Progressive motion, the one-way valve of piston is just closed, and working medium is sucked by the rear portion of piston, and the working medium of piston front portion extrudes; Piston

Compress a spring simultaneously; Coil no electric circuit when the lower half of Ac, the power that spring stores is rebounded piston, then repeats first element again.The electromagnetic pump of this structure bears the load aspect two under the effect of certain magnetic force, (1) piston extrudes the load of working medium.(2) load of storage power spring.

If utilize the voltage of all-wave shape, the garden is respectively around two groups of coils outside a pipe, two groups of coils respectively connect opposite polarity diode respectively with a end of a thread, two groups of coils separate with three blocks of soft iron plates and do electromagnetic pole, the pipe inner end is placed with the soft iron siphunculus piston of a band one-way valve equally, and respectively load onto an one-way valve in the water inlet and outlet side of piston, and three one-way valves and valve are promptly arranged to identical, be sidelong a spring in water inlet.The electromagnetic pump of this sampling device, under the effect of certain magnetic force, load can obtain the power effect of magnetic force and spring superposition, and two one-way valves of increase also make the efficient of pump improve.The load condition remarkable improvement, efficient improves greatly, surveys factually, under same power consumption, it is nearly 50% that flow increases, and increased pressure gives full play to that electromagnetic pump is simple in structure, volume is little, save metallic material, low, explosion-proof, moistureproof, the etch-proof distinguishing feature of cost.

Below in conjunction with embodiment the working principle of full wave type electromagnetic pump is described in detail.

With reference to accompanying drawing, when the single-phase voltage direction of power supply is last when negative just down, loop A is because of diode D ₁Blocking-up and no electric circuit, coil B is by diode D ₂Forward conduction energising, coil B produces magnetic field, north and south at two axial ends, and there is a natural attraction between the sexes magnetic field, north and south by means of a hollow irony rod piston that one-way valve is arranged of coil central authorities, thereby make this root irony rod piston move right valve F ₃Close, at this moment at valve F ₁To F ₂The gas or the liquid in section space are compressed, thus valve F ₁Be closed valve F ₂Be forced to open, liquid or gas flow relatively left, when the lower half of voltage be last negative down just, coil B is subjected to D ₂Reverse blocking and no electric circuit, loop A is then because of D ₁Conducting and switch on, loop A produces magnetic field, north and south at axial two ends, it is same by means of the hollow irony rod as piston that there is a natural attraction between the sexes magnetic field, north and south, and piston is moved to the left.

At this moment valve F ₁Open, gas or liquid suck, valve F ₂Be closed valve F ₃Open, working medium flows out.

Claims (3)

1, by two electromagnetic coil that on same axle center, link to each other, the electromagnetic pump that two crystal diodes, three one-way valves, electromagnetic core and the pump housing are formed, it is characterized in that magnetic force is alternately to be produced by two coils, electromagnetic core is subjected to the effect to-and-fro motion of two magnetic forces.
