Description

Electromagnetic oscillations formula submersible pump

The utility model relates to a kind of submersible pump, particularly adopts the mode of electromagnetic oscillations to realize the submersible pump of the purpose of drawing water.

Existing submersible pump great majority are centrifugal structure, and its adopts the rotation of power plant drives impeller, make water generates centrifugal force and do work, and it is serious that this pump exists mechanical wear; The power loss height, volume is big, disadvantages such as equipment heaviness.In order to overcome above-mentioned shortcoming, Patent Office of the People's Republic of China announced that notification number is CN2134503Y on May 26th, 1993, name is called the utility model patent of " moving plate formula electromagnetism submersible pump ", the alternating magnetic field that it utilizes AC electromagnetic coil to produce, make street iron to-and-fro motion, drive the diaphragm to-and-fro motion, produce pressure reduction between the water in the pump housing and do work thereby make; It has simple in structure, and power loss is low, the technique effect that component are difficult for being worn.But, thereby very easily fall the shaft bottom or the water inlet is stopped up in the river bed, thereby poor reliability because of pump housing bottom surface because its water inlet is positioned at the bottom of pump.

It is a kind of simple in structure that the purpose of the utility model is to provide, and volume is little, the electromagnetic oscillations formula submersible pump of long service life.

The technical solution of the utility model is such: it comprises the housing that is linked into an integrated entity by upper and lower half shell, place static iron core, electromagnetic coil, vibration iron core in the lower half shell, be contained in the elastic packing mechanism in the upper half shell, the axis of traction that direction of vibration is being connected when passing elastic packing mechanism with the work of vibration iron core, be fixed on the rubber setting-out dish that the axis of traction the other end and first faucal match, be positioned at as glue laminated water pond the place ahead and be contained in one-way valve on the water inlet of upper half shell roof, first shell wall is provided with the water outlet that is communicated with osculum.

In order to ensure rubber setting-out dish best vibrating effect back and forth can be arranged, do not make between the upper and lower chamber again simultaneously seepage takes place, elastic packing of the present utility model mechanism is the hollow elasticity Seal cage, it is by the sealing gasket of clamping between upper and lower half shell, place the sealing seat on the sealing gasket and be fastened on the seal ring of sealing seat port and the pressing plate that is enclosed within on the seal ring is formed, and the axis of traction stage casing is constituted axial seal.

The utility model working principle is as follows: when lead to alternating current (a.c.) in electromagnetic coil after, promptly produce a high varying magnetic field, this high varying magnetic field and elastic packing mechanism 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, the cavity of pressure elasticity sealing mechanism first, second one-way valve opens makes water enter housing because the water inlet outside pressure will be intake greater than inside pressure; 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, because rubber setting-out dish is done cyclical movement circularly, make the source, water source constantly from water outlet output, thereby the purpose of the utility model is achieved.

This practical major advantage that has kept existing electromagnetism submersible pump, simultaneously water inlet and water outlet all are arranged at pump housing top, thereby solved the blockage problem of water inlet preferably, its reliability has obtained raising by a relatively large margin, after water is drained,, thereby reduced its ocsillator strenght significantly simultaneously owing to the pump housing can not surface, and improve its cooling performance, avoided the damage of body.Add and adopt the hollow elasticity Seal cage between the upper and lower casing, the structure sealing, so oscillation effect is better, power consumption can lower.

Following structure is embodiment shown in the drawings be described in further detail the utility model.

Fig. 1 is a structural representation of the present utility model.

Electromagnetic oscillations formula submersible pump by housing, place static iron core 10 in the housing, electromagnetic coil 9, vibration iron core 17, elastic packing mechanism, axis of traction 14, rubber setting-out dish 2, one-way valve 13 to form.

Housing is divided into upper and lower two and half shells 6,8, links into an integrated entity with bolt, nut, and upper half shell 6 roofs and sidewall have water inlet 12 and water outlet 10, and one-way valve 13 is arranged at 12 inboards, water inlet.Elastic packing mechanism is a hollow elastic vibration cavity, it is by comprising that clamping is last, lower half shell 6, sealing gasket 7 between 8, place tubular sealing seat 7 on the sealing gasket 7, sealing seat 7 upper inside wall are provided with a flange, fastening the gland that is combined into by seal ring 4 and pressing plate 3 on the flange, sealing gasket 7 centers are embedded with axle sleeve 16, axle sleeve 16 and seal ring 4 fix with corresponding that section axis of traction 14, rubber setting-out dish 2 is connected by axis of traction 14 between the iron core 17 with vibration, rubber setting-out dish 2 is presented, the top in shape of following symmetry, the rank tang of its diameter and upper half shell 6 matches, static iron core 10 is positioned at vibration iron core 17 lower ends, and insulation ground insert electromagnetic coil 9, and its lead 15 draws that housing is outer to be communicated with power supply through switch or plug.

Can make the water inlet up in the course of the work in order to ensure pump, be equipped with on the upper casing top and hang circle 11.

Obviously, the utility model is compared with existing electromagnetic deep-well pump, has dependable performance, Make simple, lift height, the advantage such as power consumption is low.
