Abstract

The utility model belongs to a diving pump, which comprises a shell body comprising an upper shell body, a cylinder body, and a lower shell body, an electromagnet and a vibration iron core arranged inside the shell body, an elastic sealed cavity comprised by a sealed plug and an elastic sealed base, a transmission traction axis, a rubber water pushing plate and a single direction valve. The utility model is characterized in that: a framework ring is arranged in the elastic sealed base, because the framework ring extends out the surrounding of the elastic sealing base, the transformation and force are more uniform, the elastic strength is improved, and the using life is elongated. The utility model had advantages of reliable performance, simple production, high raising journey and long using life compared with current electromagnetic diving pump.

Description

The electromagnetism submersible pump

The utility model relates to a kind of submersible pump, the purpose submersible pump that particularly adopts the mode of electromagnetic oscillations to come practicality to draw water.

Existing electromagnetic type submersible pump, the high varying magnetic field that it utilizes AC electromagnetic coil to produce, cause the to-and-fro motion of vibration iron core, it is reciprocating to drive rubber setting-out dish and elastic sealing element, thereby makes the purpose that produces pressure reduction between the interior water of pump and the external world and reach suction.It is low that it has power loss, the nonabradable technique effect of component.But, elastic sealing element is simple rubber body and directly is fixed on the transmission traction axle with its upper and lower vibration, so elastic sealing element distortion, discontinuity, elasticity weakens easily, thereby influenced other technical performance of submersible pump, big inadequately as flow, shorten working life, and lift does not reach due height etc.

It is a kind of easy to assembly that the purpose of the utility model just is to provide, long service life, the electromagnetism submersible pump that technical performance is stable.

The technical solution of the utility model is such: it comprises housing, place in the lower shell body the closed circuit magnet case electromagnet of forming by yoke and street iron, vibrate iron core with epoxy sealing, be contained in the hollow elasticity Seal cage of forming by elastic packing seat, sealing plug in the cylindrical shell in the middle of the housing, be contained in rubber setting-out dish in the upper shell, the one-way valve and pass the transmission traction axle that the elastic packing chamber connects rubber setting-out dish and vibrates iron core of intaking.The Outlet of described electromagnet is connected with power line, and upper shell is provided with inlet channel: in the described elastic packing seat steel frame ring is housed.

Steel frame ring of the present utility model is formed jacket casing and transmission traction axle secure fit by the jacket casing and the umbrella stand that merges the hole that has that is distributed in around the jacket casing.

Housing of the present utility model is formed by connecting by bolt, nut by upper shell, cylindrical shell, lower shell body.Wherein the sealing plug clamping is between upper shell and cylindrical shell, and the elastic packing seat is contained between cylindrical shell and the lower shell body.Like this, both can guarantee that rubber setting-out dish has best vibrating effect back and forth, did not make between the upper and lower chamber again seepage takes place.

Working principle of the present utility model is such: when after leading to alternating current (a.c.) on the electromagnet, promptly produce a high varying magnetic field, this high varying magnetic field and elastic packing chamber cooperatively interact, and order about vibration iron core and rubber setting-out dish and do periodic upper and lower to-and-fro motion.When rubber setting-out dish is descending, pressure elasticity Seal cage first, second because the water inlet outside pressure one-way valve opens of will intaking greater than inside pressure, make water enter upper shell: when rubber setting-out dish is up, because rubber setting-out dish makes the water inlet inside pressure greater than outside pressure to the pressure of water, order about into water closed check valve, at this moment, because of forming a bigger pressure reduction between inboard, water inlet and the water outlet inner end, water is swashed by water outlet penetrate, like this, rubber setting-out dish is done cyclical movement circularly, make the source, water source constantly from water outlet output, thereby realized the purpose of drawing water.

Because the elastic packing seat in the elastic packing chamber is provided with framework ring, thereby increased elastic packing seat elastic strength, and make elastic packing seat distortion and stressed more even, improved the mechanical property of whole electromagnetism submersible pump, compare with the elastic packing seat that does not have bone to add ring, elasticity improves, stable mechanical performance, after one week of continuous operation, the complete machine performance does not almost have attenuation phenomenon.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is a structure sectional view of the present utility model.

Fig. 2 is the schematic perspective view of framework ring.

Fig. 3 is the sectional view of Fig. 2.

Fig. 4 is the plan view of Fig. 2.

The electromagnetism submersible pump places electromagnet 13, vibration iron core 11 in the housing 6 by housing 6, and elastic packing chamber 10, transmission traction axle 5, rubber setting-out dish 4 and one-way valve 1 are formed.

Housing 6 is divided into upper shell 6-1, cylindrical shell 6-2, lower shell body 6-3, links into an integrated entity by bolt, nut, and upper shell 6-1 roof and sidewall have water inlet 2 and water outlet 3, and one-way valve 1 is arranged at 2 inboards, water inlet.Elastic packing chamber 10 is a hollow elastic vibration cavity, it by clamping the sealing plug 7 between upper shell 6-1 and the cylindrical shell 6-2 and be contained in cylindrical shell 6-2 and lower shell body 6-3 between elastic packing seat 9 form; The framework ring 8 of rigidity is housed in the elastic packing seat 9, framework ring 8 is made up of the umbrella stand 8-2 that jacket casing 8-1 3 bands upward evenly distributed with being welded on jacket casing 8-1 that are fixed on the transmission traction axle 5 merge hole 8-3, since framework ring 8 be stretched in the elastic packing seat 9 around, thereby the elastic strength and the working life that have strengthened elastic packing seat 9, when also making simultaneously elastic packing seat 9 be subjected to 5 motions of transmission traction axle, distortion and stressed more even, thus make whole elastic packing chamber 10 have better elasticity.Rubber setting-out dish 4 is connected by transmission traction axle 5 between the iron core 11 with vibration: rubber setting-out dish 4 goes to upper and lower symmetrical " discus " shape, its diameter covers just on the recess of upper shell 6-1: electromagnet 13 is positioned at vibration iron core 11 lower ends, and with epoxy resin 12 sealing form closed circuit magnet case by yoke 13-1 and armature 13, its Outlet is connected with power line 14.

Obviously, the utility model is compared with existing electromagnetic deep-well pump, and having performance can Lean on, make simply lift height, the advantages such as long service life.
