Abstract

A double-suction high-efficiency submersible motor pump comprises a motor rotor 1, a rotor shaft 2, a bearing 3, an oil chamber 4, an oil chamber cover 5, a volute 8, an impeller 9 and a water inlet joint 10. The motor rotor 1 is located on the upper portion of the rotor shaft 2, the oil chamber 4 is installed in the middle of the rotor shaft 2 through the bearing 3, and the oil chamber cover 5 and the water inlet joint 10 are installed on the lower portion of the rotor shaft 2 in sequence. The impeller 9 is installed at the bottom of the rotor shaft 2, and the volute 8 is installed on the water inlet joint 10. The impeller 9 consists of a left blade 94, a right blade 95, a left front cover plate 96, a right front cover plate 97 and a rear cover plate 98. Due to the fact that a single-suction water inflowing mode is changed into a double-suction water inflowing mode, and axial force generated by the rotation of the impeller is changed into bidirectional instead of unidirectional, thereby effectively resolving the problems of bearing fatigue operation and short service life which are caused by the overlarge axial force of the submersible motor pump. Compared with the prior art, the born axial force of the submersible motor pump can be effectively reduced, service life of the load-bearing bearing is prolonged, and reliability of the submersible motor pump is improved.

Description

The efficient Submerged Motor Pumps of double suction
Technical field
The utility model relates to a kind of Submerged Motor Pumps, the particularly a kind of life-span that can effectively improve the load-bearing bearing, improves the efficient Submerged Motor Pumps of double suction of the reliability of Submerged Motor Pumps.
Background technique
Submerged Motor Pumps mainly comprises rotor 1, rotor shaft 2, bearing 3, grease chamber 4, grease chamber's lid 5, lid pump 6, impeller 7 and volute 8(are shown in Fig. 1-4), rotor 1 is positioned at the top of rotor shaft 2, grease chamber 4 is installed in the middle part of rotor shaft 2 by bearing 3, grease chamber's lid 5 and lid pump 6 are installed in the bottom of rotor shaft 2 successively, impeller 7 is installed in the bottom of rotor shaft 2, volute 8 is installed in and covers on the pump 6, impeller 7 is a single suction impeller, preceding water sucking mouth 71 and water outlet 72 are arranged on it, comprise blade 73, front shroud 74 and back shroud 75, blade 73 is installed between front shroud 74 and the back shroud 75, and anti-blade 751 is arranged on the back shroud 75.The axial force P=P that the submersible electric pump motor rotor is born 1+ P 2+ P 3, P wherein 1Be rotor deadweight, P 2(because the impeller front and rear cover plate is asymmetric, the power that the water intake size causes is called cover plate power P for impeller cover power 2), P 3Be impeller dynamical reaction (because the impeller high speed rotating, liquid enters the back from impeller port ring and changes direction, and the power that raising speed is produced is called dynamical reaction).Because the rotor of Submerged Motor Pumps all adopts vertical installation, the deadweight P of rotor 1Fix.Impeller cover power P 2Relevant with water flow, flow is big more, P 2Big more; In order to reduce impeller cover power P 2, on the back shroud 71 of the impeller 7 of Submerged Motor Pumps, added anti-blade 72(shown in Fig. 2,3), to reduce the axial force P that rotor was born.Impeller dynamical reaction P3 is relevant with pumping head, and the leaf pumping head is high more, P 3Big more.Because the axial force P of rotor is all born by the motor bottom end bearing, causes motor bearings stressed excessive, chronic fatigue moves, and has a strong impact on the working life of water pump.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and provide a kind of double suction efficient Submerged Motor Pumps, its water intake mode is a double suction, the axial force that impeller rotation produces by unidirectional become two-way, make the axial force that Submerged Motor Pumps bore reduce, so that improve the life-span of load-bearing bearing, improve the reliability of Submerged Motor Pumps.
The technical solution of the utility model is: the efficient Submerged Motor Pumps of a kind of double suction, comprise rotor, rotor shaft, bearing, grease chamber, You Shigai, volute, impeller and water inlet joint, rotor is positioned at the top of rotor shaft, the grease chamber is by the middle part of Bearing Installation at rotor shaft, grease chamber's lid and water inlet joint are installed in the bottom of rotor shaft successively, impeller is installed in the bottom of rotor shaft, and volute is installed in on the water joint.
The further technological scheme of the utility model is: impeller is a double-entry impeller, and left water sucking mouth, right water sucking mouth and water outlet are arranged on it.
The further again technological scheme of the utility model is: impeller is made up of lobus sinister sheet, lobus dexter sheet, left front cover plate, right front cover plate and back shroud, lobus sinister sheet and lobus dexter sheet are installed between left front cover plate, the right front cover plate, the lobus sinister sheet of back shroud between left front cover plate and right front cover plate and the middle of lobus dexter sheet.
The utility model is because water intake mode changes double suction into by single suction, the axial force that impeller rotation produces by unidirectional become two-way, effectively solved the bearing fatigue work that Submerged Motor Pumps causes because of axial force is excessive, the defective that working life is short, compared with prior art, the axial force that can effectively reduce Submerged Motor Pumps and born in the life-span of improving the load-bearing bearing, improves the reliability of Submerged Motor Pumps.
Below in conjunction with figure and embodiment detailed structure of the present utility model is further described.
