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

[0039] 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:

[0040] The external water body enters the isolation and shielding cavity from bottom to top th...

Abstract

The invention relates to an application method and a structure of a pump including an immersion pump supported by air jacking seal. The application method comprises: I, the general situation of the pump: a rotor (2) of a motor is at least surrounded by narrow metal seal isolation (4) or a wide metal seal isolation (5) in a three-dimensional way, and a charging connector mechanism (P) is at least arranged on the bottom part of the seal isolation; II, the preparation work before application: the inner part of a liquid pump is charged through the charging connector mechanism (P), and when the charging pressure is larger than the pressure of the immersion depth of the pump, the pump can be placed under a liquid level and powered on for working, and the pump can also be placed above the liquid level for working; liquid molecules in the pump cannot be leaked when the pump is running; and all splicing gaps related to the outer surface of the pump are connected through a detachable welding process. The continuous cumulative time of one-time working and idling of the pump underwater depends on the service life (about more than 30 years) of the motor, and the diving depth of the pump is infinite, so that a condition is created for the pump to become an update product of an immersible pump, and the structure of the pump is probably more suitable for a common water pump.

Description

technical field [0001] The present invention relates to the use method and structure of a deep submersible pump (both submersible depth and one-time sustainable submersion time are infinite) and an internal pump supported by an air jacking seal (the molecules of the liquid in the pump will not leak out) . 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 dam...
