Abstract

The invention belongs to a pump, and in particular relates to a single-rod multi-head transecting spiral submersible pump. The single-rod multi-head transecting spiral submersible pump consists of a submersible motor, a motor bracket, a coupling, a suction and drainage disk, a thrust bearing, a multi-head spiral rotor, a shell, a gathering and delivering section, a discharge pipe and bolts, wherein the submersible motor is connected with the suction and drainage disk through the motor bracket and the coupling; the thrust bearing is arranged on a main shaft; the multi-head spiral rotor is machined on the main shaft; the tooth end face of the multi-head spiral rotor is matched with the rotary sliding surface of the suction and drainage disk; the shell is connected with the suction and drainage disk through the bolts; and the upper end of the shell is connected with the gathering and delivering section and the discharge pipe. The single-rod multi-head transecting spiral submersible pump has the advantages of strong discharge pressure, a few structural moving components, long service life and low cost, is particularly suitable for thick fluid media and long-distance transmission, and has the characteristics of energy conservation and high efficiency.

Description

technical field

[0001] The invention belongs to pumps, more precisely, it is a single-rod multi-head cross-cut screw submersible pump. Background technique

[0002] At present, there are general types of submersible pumps, such as multi-pole centrifugal submersible pumps, single-screw submersible pumps, etc. The efficiency of multi-pole centrifugal submersible pumps is low under high-pressure conditions, and there are many stages of impellers, requiring machining accuracy and assembly accuracy. High; single-screw submersible pump, the stator sleeve wears quickly, the failure rate is high, and the service life is short. Contents of the invention

[0003] In view of this, the object of the present invention is to provide a single-rod multi-head transverse-cut screw submersible pump with high efficiency, energy saving and long service life.

[0004] The purpose of the present invention is achieved through the following technical measures: a single-rod multi-head cross-cut sc...
