Rotator for well cleaning with clearance seal and labyrinth seal

Abstract

The invention relates to a rotator for well cleaning with clearance seal and labyrinth seal, and belongs to the technical field of deep well cleaning. The rotator for well cleaning with clearance sealand labyrinth seal comprises a rotator body, wherein a water spraying channel is formed in the side face of the rotator body in the radial direction; a bush is embedded in the rotator body; a plurality of grooves are formed in the inner wall of the bush in the circumferential direction and are in clearance fit; the single-side clearance of the grooves is smaller than the diameter of water molecules; a high-pressure water channel is formed in shaft rod in the axial direction; a high-pressure water side channel communicating with the high-pressure water channel is formed in the side face of theshaft rod in the radial direction; the high-pressure water side channel communicates with a water spraying channel; a connector connected with a high-pressure water conveying device is arranged at the end of the shaft rod; and the two ends of the rotator body are in threaded connection with cover-shaped nuts to fix the bush from the end parts. The rotator for well cleaning with clearance seal andlabyrinth seal provided by the invention is scientific and reasonable in structural design, easy to manufacture, convenient to assemble and disassemble and safe and reliable to use, auxiliary workinghours are reduced on the premise that the cleaning effect and the cleaning quality are guaranteed, shutdown caused by blockage of the rotator is avoided, the risk of well cleaning failure is reduced,and the well cleaning efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of deep water well cleaning, and in particular relates to a rotating body for cleaning wells with a gap seal and a labyrinth seal. Background technique [0002] After all kinds of deep water wells are self-constructed, due to the action of underwater microorganisms, rust, metal ions, etc., they will form attachments on the filter, affecting the water permeability, resulting in a decrease in water discharge or recharge capacity, failing to meet the design requirements, and even being abandoned in severe cases. , into a dead well. Therefore, it is necessary to carry out regular cleaning and maintenance on the well wall after the completion of the well, so as to restore the water discharge or recharge ability and prolong the service life of the completed well. [0003] The traditional well cleaning method is to use a compressor to send compressed air into the well. The compressed air expands and ruptures rapid...

Problems solved by technology

The advantage of this cleaning method is that it is non-polluting, thorough and clean after washing, and the effect is remarkable; the disadvantage is that the preparation time is long and the efficiency is low, often because the rotary body of the rotary nozzle is blocked, the work is stopped and the work is eliminated, and even the well cleaning fails.
