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

[0036] Taking the submersible pump as an example, the core overview of the present invention: in order to prevent the motor rotor 2 from contacting with the external water body that seeps into the submersible pump and eventually damage the motor, at least a three-dimensional surrounding metal seal isolation is formed for the motor rotor 2 Shield the cavity, 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 In contact with the motor rotor 2, it can only enter through the shaft seal position 7 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, prevented. live:

Abstract

The invention relates to a pump structure utilizing air jacking sealing operation and comprising a deep submersible pump and an amphibious use method of the pump structure. The pump structure comprises the following steps: at least a rotor (2) is surrounded by a narrow metal sealing isolation (4) or a wide metal sealing isolation (5) in a three-dimensional form, and a motor shaft seal (7), a charging connector mechanism (P) and a pressure display device interface (K) are arranged at the bottoms shielded by the narrow metal sealing isolation (4) and the wide metal sealing isolation (5); and all splicing gaps of a fully-sealed metal sealing isolation cavity are realized through a welding process. Due to the fact that the continuous cumulative time of one-time working and idling of the pump structure under water depends on the service life (about 30 years) of a motor and the diving depth is infinite, the submersible pump can be possibly manufactured into a structural form in which liquid molecules in the pump cannot be leaked during operation, and the cost, namely the cost performance, of the submersible pump is possibly higher than that of a product in the prior art, conditions are created for at least becoming an updating product of the submersible pump, and the structure of the pump structure is more suitable for a common water pump.

Description

technical field [0001] The invention relates to a waterproof (liquid) sealed submersible pump using the principle of air jacking (including the submersible depth of the submersible pump and the one-time continuous submersion time can reach unlimited) pump structure and its submersible and land omnidirectional usage instructions. 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 ...
