Description

Technical Field

[0001] The utility model relates to the technical field of a ground diagnosis device for a screw pump, and in particular to a ground diagnosis device for a screw pump. Background Art

[0002] The screw pump is a new type of pump that works on the principle of rotary meshing positive displacement. It is a positive displacement rotor pump that relies on the volume change of the sealed chamber formed by the screw and the bushing to suck in and discharge the liquid. The screw pump is divided into single screw pump, double screw pump, triple screw pump and five screw pump according to the number of screws. The characteristics of the screw pump are stable flow, small pressure pulsation, self-priming ability, low noise, high efficiency, long life and reliable operation; and its outstanding advantage is that it does not form eddy currents when conveying the medium, is insensitive to the viscosity of the medium, and can convey high-viscosity media. Compared with general pumps, it has obvious advantages. Therefore, the screw pump is widely used in sand wells and heavy oil wells. The screw pump is affected by the environment in the well for a long time, is prone to aging during work, and the screw may break. In this case, the staff needs to enter the well for maintenance. The environmental conditions in the well cannot be observed intuitively, which makes it inconvenient for the staff to repair and further increases the work intensity. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
