Abstract

The invention discloses a submersible pump which is used by matching with a standard well bore and put into the well bore by the wire rope passing through a flying ring; the lower side of a two-level submersible pump chamber is provided with a one-level submersible pump chamber, a water inlet network, a submersible motor in sequence, the lateral external wall of the pump chamber is provided with an annular elastic seal bag communicated with the inner cavity of the pump chamber, a rigid upper body and a lower body of the seal bag are cast into a whole with the lateral external wall of the pump chamber and connected by a rigid guiding connection bar, the peripheries of the upper body and lower body are provided with an annular groove which is matched with an annular lug boss of a rubber bag and sealed by the extrusion of an elastic ring, the annular elastic seal bag is communicated with the inner cavity of the pump chamber through a guiding hole on the lateral wall of the pump chamber, and the axes of the guiding hole is tangent with the peripheral contour line of an impeller. The invention has the beneficial effects of realizing the efficient sealing, and can be applied to shaft wells with different caliber and depth with improved work efficiency and high pump lift.

Description

With the matching used submersible pump of standard pit shaft

Technical field

The present invention relates to a kind of and the matching used submersible pump of standard pit shaft.

Background technique

Submersible pump the earliest, pump chamber top mouth links with conduit pipe, by conduit pipe water is exported deep-well, does not make full use of the standard pit shaft, uses trouble, causes certain waste.Not having pipe deep-well water delivery apparatus is to utilize the water delivery of standard pit shaft for saving conduit pipe, but in the starting stage of submersible pump ejection water, poorly sealed, only be suitable for deep-well, make trouble, error probability increases, hermetic seal scheme complicated operation, wayward, can only be used for well and fetch water.

Summary of the invention

The objective of the invention is to overcome above-mentioned deficiency, a kind of and the matching used submersible pump of standard pit shaft are provided, simple in structure, sealing is tight, highly versatile.

Technological scheme of the present invention is: a kind of and matching used submersible pump of standard pit shaft, it is characterized in that: the cyclic spring sealed bladder that is communicated with the pump chamber inner chamber is arranged on pump chamber side upper wall, the rigidity upper and lower body periphery of cyclic spring sealed bladder has annular groove, cooperate with the annular boss of rubber bag tank, by the spring crush seal, pod apertures on the pump chamber sidewall of cyclic spring sealed bladder through being distributed on the impeller correspondence communicates with the empty inner chamber of pump, and the axis of pod apertures and impeller periphery profile line are tangent.

Beneficial effect of the present invention: realize efficient sealed.Be applicable to the tube well of the different bores and the degree of depth, the working efficiency raising reaches the lift height.
