Embodiment Construction

[0027] Overview of the core of the present invention: In order to prevent the motor rotor 2 from contacting with the external water body that penetrates into the submersible pump and eventually damage the motor, at least a metal-sealed isolation shielding cavity with a three-dimensional surrounding property is formed for the motor rotor, and only The rotating shaft 6 of the motor rotor 2 outputs rotational force to the liquid pump 9 through the shaft seal position 7. Obviously, if the external water body wants to enter the cavity (inner cavity) formed by the metal sealing isolation shield and contact with the motor rotor 2, then It can only enter through the shaft seal position 7 upwards along the rotating shaft 6. However, as long as the air pressure in the isolation and shielding cavity is large enough, it can fully support (prevent) the external water body from passing through the above-mentioned gap from top to bottom. The shaft seal position 7 enters the isolation shieldin...

Abstract

The invention discloses a submerged pump jacked by air and equipped with a waterproof and sealed structure and a detachable and replaceable motor stator. The submerged pump comprises a liquid pump (9) in a conventional structural form, wherein the liquid pump (9) is driven by a dragging motor through a rotary shaft (6) of the motor, and comprises a rotor (2) and a stator (1) embedded in a winding; the submerged pump is characterized in that at least the rotor (2) is surrounded by a narrow type metal sealing isolation part (4) in a three-dimensional manner; in addition, a motor shaft sealing part (7) and a charging connector mechanism (P) are arranged at the inverse conical bottom of the narrow type metal sealing isolation part (4); and all splicing gaps of the narrow type metal sealing isolation part (4) are connected through a non-detachable welding process. The accumulative time of operation time and idleness time of the submerged pump under water in one time is far more than that in the prior art; a submerged pump in the prior art needs to go ashore to be maintained at regular intervals (normally several months, and at most one year), however, the submerged pump provided by the invention is not required to go ashore so frequently; therefore, the submerged pump provided by the invention has the potential to be the updated product of the submerged pump; and in addition, the structure of the submerged pump is also applicable to a common water pump.

Description

technical field [0001] The invention relates to a submersible pump with a waterproof sealing structure supported by air and a detachable and replaceable motor stator. Background technique [0002] At present, submersible pumps of various specifications and models emerge in an endless stream, which is a kind of power equipment with a wide range of uses. Standard sealing ring to act as) to resist the infiltration of external water into the submersible pump drive motor. [0003] For this reason, when people use submersible pumps, the general maintenance interval will not be too long (as little as a month and as many as a year is difficult to exceed a year - the greater the diving depth, the shorter the maintenance interval of the submersible pump), as long as After use, it must be regularly lifted out of the water for maintenance (not damage repair), so that the seepage water that has entered the submersible pump motor has a chance to be artificially removed in time, so as to ...
