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 present invention relates to a submersible pump of utilizing the air jacking waterproof sealing principle. A motor stator of the submersible pump can be disassembled and replaced, and the submersible pump comprises a liquid pump (9) having a conventional structure format and driven by a rotating shaft (6) of a traction motor composed of a rotor (2) and a stator (1) embedded in a winding and is characterized in that the rotor (2) is at least surrounded by a narrow metal sealing isolator (4) in a stereo manner, a motor shaft seal (7) and a charging connector mechanism (P) are arranged at the inverted conical bottom of the narrow metal sealing isolator (4), and all splicing gaps involved in the narrow metal sealing isolator (4) are connected via a non-removable welding technology. The underwater one-off working and idle cumulative time of the submersible pump of the present invention is much more than the prior art, the products in the prior art need to be maintained regularly, for example usually a few months, or one year at most, but the submersible pump of the present invention does not need to be maintained regularly, so that conditions are created for the submersible pump of the present invention to become the upgrading product of the submersible pump. The structure of the submersible pump of the present invention is also suitable for the general water pumps.

Description

technical field [0001] The invention relates to a submersible pump (a detachable and replaceable motor stator) utilizing the principle of air jacking and waterproof sealing. 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...
