Abstract
The utility model relates to the improvement of a miniature vibration type submersible pump, and the structure of the utility model is characterized in that the connecting point of an air gap cavity of the existing miniature vibration type submersible pump and an upper shell body is provided with a small water inlet, causing liquid to fill the air gap cavity naturally. When the utility model works, the air gap cavity does not full of gas, but full of liquid. The utility model has good heat dissipation, low noise and long service life, and the utility model avoids mechanical impact.
Description
The utility model relates to the improvement of miniature vibration type immersed pump.
Existing micro-vibration immersed pump, working principle is to produce electromagnetic force by Ac to make armature produce vibration, thereby drive a sleeve liquid mechanism vibrations that comprises valve and extract liquid, its power is a pair of static electromagnet and movable armature, rather than motor, its deficiency is to be full of air in the cavity of electromagnet and armature formation, noise is big during vibration, and it is bad to dispel the heat, and has strong mechanical impact to produce, air is little to whole vibration system damping, and service life of equipment is short.
The purpose of this utility model be to avoid above-mentioned deficiency of the prior art and provide a kind ofly improve electromagnet and armature operating conditions at air gap chamber full of liquid, reach the immersed pump that good heat dissipation, vibration damping increase, reduce the air gap chamber topping up body running of mechanical impact.
The purpose of this utility model can realize by following measure: air gap chamber and upper shell joining place at existing micro-vibration immersed pump are provided with the water inlet, make liquid be full of the air gap chamber naturally, the air gap chamber is not a gassy but full of liquid reaches the utility model purpose during work.
Accompanying drawing is the utility model structural drawing.
The utility model has following advantage compared to existing technology: because this practicality Novelly at air gap cavity and upper shell joining place aperture is set, makes take air to medium Change is take liquid as medium, and having one is good heat dissipation; The 2nd, the vibration damping increases, Avoid mechanical impact, long service life; The 3rd, reduce noise.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
The utility model is made up of cable (1), upper casing liquid outlet (2), upper shell (3), electromagnet component (4), armature assembly (5), lower shell body (6), feed liquor one-way valve (7), liquid entering hole (8), air gap chamber (9), water inlet (10), hyperbaric chamber (11), low-pressure cavity (12), with upper shell (3) joining place aperture (10) is set in air gap chamber (9), when carrying out work, making original gassy is that to become full of liquid be that medium has reached the purpose of this utility model for the air gap chamber of medium.
Claims (1)
- A kind of by cable (1), upper casing liquid outlet (2), upper shell (3), electromagnet component (4), armature assembly (5), lower shell body (6), feed liquor one-way valve (7), liquid entering hole (8), air gap chamber (9), hyperbaric chamber (11), the immersed pump of the air gap chamber topping up body running that low-pressure cavity (12) is formed, it is characterized in that this immersed pump also is made up of water inlet (10), at upper shell (3) nexine electromagnet component (4) is set, in electromagnet component (4) bottom air gap chamber (9) is set, at lower shell body (6) nexine low-pressure cavity (12) and hyperbaric chamber (11) are set, last, armature assembly (5) is set between lower shell body, at upper shell upper casing liquid outlet (2) is set, at lower shell body liquid entering hole (8) is set, water inlet (10) is set in air gap chamber and upper shell joining place.
