Abstract
A multistage submersible pump for wells comprises a motor and a motor shaft, wherein a motor housing is arranged outside the motor; a front bearing, a rear bearing and a rear bearing seat are arranged on the motor shaft; a pedestal is arranged on the end part of the motor housing; a capacitor is arranged in the pedestal; the front bearing is arranged at one end of a sealed cylinder; an oil seal is arranged in the sealed cylinder; the motor has an extracted cable; the motor housing is connected with a pump housing through a support; impellers and guide vanes arranged on a pump shaft are arranged in the pump housing; and a filter device and a connection water adapter are arranged on the pump housing. The multistage submersible pump is characterized in that the pump shaft and the motor shaft are selected from the same integrated shaft; and 5 to 20 impellers and guide vanes are arranged on the pump shaft, that is to say, the pump has serial connection of 5 to 20 stages. Compared with the prior art, the multistage submersible pump can overcome the difficulty in adjusting the concentricity of two shafts by selecting one shaft as the pump shaft and the motor shaft, thereby preventing jamming due to the vibration of the impellers during high-speed rotation after connecting the two shafts through a coupling; and the scheme particularly suits the multistage pump and can connect 5 to 20 stages in series.
Description
Technical field
The utility model relates to Submerged Motor Pumps, particularly relates to well use multistage submersible electric pump.
Background technique
Along with the increase of water consumption and the mankind itself pollution to surface water resources, therefore, constantly to the deep layer development, well is deepened gradually in phreatic exploitation, and the progression of Submerged Motor Pumps is more and more, so people have produced well use multistage submersible electric pump.Described well use multistage submersible electric pump is mainly by motor and two parts of pump, owing to work in water, the sealing between motor and the pump is also very important, the impeller and the stator of adding multistage pump are in series, pump shaft is long, the motor rotating power be passed to pump, and the transfer mode of its rotating shaft is crux very.Between the motor shaft of existing well use multistage submersible electric pump and the pump shaft coupling is installed, the shortcoming that is existed by the coupling transferring power has: the one, and pump shaft is long, and two shaft concentricities are installed difficulty; The 2nd, the rotating speed height reaches about 2600 rev/mins, and coupling connects the back impeller and rocks easily, and phenomenon gets stuck.Existing well use multistage submersible electric pump is poorly sealed close in addition, easily infiltration.Because Submerged Motor Pumps works under deep-well, the elastic cable paper that motor is drawn easily disorderly around, both influenced work, influence elastic cable paper working life again.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of assurance motor shaft concentric with pump shaft, omit assembling, avoiding impeller to shake, get stuck because of coupling; The motor shaft sealing is reliable, avoids infiltration; Particularly motor outgoing cable line be installed with disorderly around, improve the elastic cable paper well use multistage submersible electric pump in working life.
The technological scheme of the utility model well use multistage submersible electric pump is: comprise motor and motor shaft, motor has motor housing outward, fore bearing and rear bearing and rear bearing block are arranged on the motor shaft, motor housing end mounting base, electric capacity is installed in the base, fore bearing is installed in of sealed cylinder, oil seal is arranged in the sealed cylinder, motor has the outgoing cable line, and motor housing connects pump case through support, and the impeller and the stator that are installed on the pump shaft are arranged in the pump case, the pump case upper end is installed filtering device and is connected water swivel, it is characterized in that described pump shaft and motor shaft are whole the same axises, described impeller and stator are only respectively done for oneself 5-20, and promptly pump is the series connection of 5-20 level.
Well use multistage submersible electric pump of the present utility model, compared with the prior art, outstanding characteristics are that pump shaft and motor shaft are made the same axis, overcome the problem of diaxon connection concentricity difficulty, avoid simultaneously rocking because of coupling connects back impeller generation under high speed rotating, cause the phenomenon that gets stuck, the progression that is specially adapted to pump is many, the 5-20 level of can connecting.
Well use multistage submersible electric pump of the present utility model, its described oil seal are one and go up oil sealing and two following oil sealings, set up two following oil sealings on the basis of oil sealing on, especially two overlapping installations of following oil sealing, good sealing effect, motor is not intake, and is safe in utilization.Be shaped on line embedding groove on its described support, the outgoing cable line of motor outside housing, is shaped on line embedding groove through line embedding groove on support, line embedding groove vises elastic cable paper, elastic cable paper is connected from motor guide to the outside, avoids random string coiling, help installing the work with pump, improve elastic cable paper working life.
