Problems solved by technology

[0009] It is to start with subverting the existing waterproof sealing link of the submersible pump in terms of structure (using the principle of air jacking and sealing), and at the same time solve the problem of structural treatment of water (liquid) molecules in the pump body that will not leak to the outside

Embodiment Construction

[0038] Summary of the core of the present invention: In order to prevent the motor rotor 2 from contacting with the external water body that infiltrates 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 2, 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 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 shielding cavity is large enough, it can be fully supported from top to bottom, that is, blocked:

[0039] The external water body enters the isolation and shielding cavity from bottom to top through the shaft seal ...

Abstract

According to a water pump structure designed according to an air jacking sealing principle and comprising an immersion pump, at least a rotor (2) is stereoscopically surrounded by a narrow metal sealing isolation part (4) or wide metal sealing isolation part (5). In addition, a motor shaft seal (7), an inflation nozzle mechanism (P) and a pressure display device interface (K) are arranged at the bottom of the narrow metal sealing isolation part (4) or wide metal sealing isolation part (5). All splicing joints of a full-sealed type metal sealing isolation cavity of the water pump structure arerealized through a welding process. Considering that the one-time underwater working and idling continuous cumulative time depends on the service life of a motor (about 30 years) and the diving depthis infinite, the water pump structure can be manufactured into a structure form that liquid molecules in the pump can not leak out during operation, the cost, namely the cost performance, may be higher than that of products in the prior art, conditions are created for the water pump structure to become a new generation product for the immersion pump, and the structure is possibly more suitable fora common water pump.

Description

technical field [0001] The invention relates to a waterproof (liquid) sealed submersible pump (including a deep submersible pump) using the principle of air jacking, and a pump structure capable of not leaking liquid molecules in the pump to the outside during operation and a use method thereof. 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)...
