Description
Technical Field
The invention belongs to the technical field of water pumps, and particularly relates to an anti-rotation guide vane string of a deep well pump.
Background
The deep well pump is a pump immersed in an underground water well to pump and convey water, after a motor works, the water in the well is pumped up, and because the inner impeller rotates at a high speed, the liquid in the well rotates along with the impeller, the liquid flies away from the impeller to be ejected outwards under the action of centrifugal force, the ejected liquid is collected in guide vanes and conveyed to the next stage of guide vanes, the pressure is gradually increased, and then the liquid is discharged from the outlet of the pump. The structure of the guide vane cluster is that the guide vane cluster is fixedly compressed by three parts of the water outlet joint, the pump barrel and the water inlet joint, so that the guide vane clusters cannot rotate mutually, and the longer the guide vane cluster is, the larger the compression force is.
Along with the continuous decline of the underground water level, the deep-well pump becomes an ideal water lifting tool for people, so that the development of the deep-well pump industry is extremely rapid. Due to the decrease of the underground water level and the rise of high-rise buildings, the lift of the deep well pump is required to be continuously improved, and the lift is increased from tens of meters to hundreds of meters to thousands of meters. With the increase of the pump lift, the rotation force of the liquid in the pump is gradually increased, and the rotation force and the pump lift are basically and synchronously increased. The rotation force can push the guide vane and the cover plate to rotate relatively, and the rotation direction is opposite, so that the higher the pump lift is, the higher the rotation force is.
Once the rotation is generated, the lift and the flow of the well pump can be greatly reduced, the well pump can not work normally when serious, the guide vane and the cover plate can be worn seriously, and the guide vane and the cover plate are adhered together, so that the water pump is blocked and scrapped. In order to solve the problems, a plurality of manufacturers can only increase the compression amount for preventing rotation and increase the compression force on the guide vane and the cover plate, and the method has two defects: firstly, crushing plastic parts; secondly, the guide vane string component is bent under excessive pressure, so that the water pump is blocked.

Further, two symmetrical clamping grooves III are formed in the inner wall of the upper end of the guide vane, and two symmetrical clamping grooves III are formed in the inner wall of the lower end of the guide vane; two symmetrical clamping grooves I are formed in the inner wall of the opening at the upper end of the water inlet joint; the inner wall of the opening at the lower end of the water outlet section is provided with two symmetrical clamping grooves II.
Further, the guide vane comprises a hollow annular body and a disc-shaped body, wherein the disc-shaped body is fixed in the hollow annular body, the clamping groove III is formed in the inner walls of the upper end and the lower end of the hollow annular body, a through hole is formed in the middle of the disc-shaped body, and spiral guide grooves are distributed on the bottom surface of the disc-shaped body around the through hole.
Further, the cover plate and the guide vane have the same outer diameter.
Compared with the prior art, the invention has the following outstanding and beneficial technical effects: the water outlet section, the adjusting washer, the cover plate, the guide vane and the water inlet section form a whole, so that the matching piece of the whole pump cannot rotate relatively. The impeller and the pump shaft also form a whole, the whole is called an impeller cluster, the impeller cluster rotates at high speed in a corresponding space of the pump cavity (guide vane cluster) to pump water to a high place, and the two whole (the impeller cluster and the guide vane cluster) rotate one and are static to form normal work. The water inlet joint and the water outlet joint only apply a normal pressure to the pump assembly, and the whole guide vane string cannot rotate relatively, so that the plastic part cannot be crushed; and the guide vane string assembly is not bent due to overlarge pressure, so that the water pump is blocked.
