Abstract
The present invention belongs to the field of liquid medium conveyance and the submersible oil pump includes pump wheel, guide blade, motor stator, motor rotor, pump neck, pump head, sleeve, and electric cable. The motor rotor is mounted in the stator cavity through the front bearing support and the back bearing support with separated sliding beairng and thrust bearing, and the pump wheel is mounted in the back part of the pump shaft and has guide blade around it. The submersible oil pump features that the filter mesh to prevent particle from entering to the pump cavity, the sleeve on the motor stator and the pump neck are combined to form one liquid guiding cavity connnected to the liquid outlet passage in the head of pump and the pump neck has electric socket inside it.
Description
(1) technical field
The invention belongs to the transportation art of liquid medium.
(2) technical background
Pump is the visual plant of fed sheet of a media, and the liquid medium that is widely used in oil, chemical industry is carried and agricultural irrigation field.The kind of pump is a lot, and as oil pump, water pump, acid-proof pump etc., its kind of drive all is the traditional approach by driven by motor, and this kind kind of drive is difficult to stop the leakage problem of pump.The oilling machine that particularly is used for transfer oil at present, its pump leakage problem in gasoline feed or diesel oil process is very general.In addition, because motor and pump are splits, thereby big, the installation inconvenience that takes up room.
(3) summary of the invention
The invention provides the oil-immersed pump that a kind of motor and pump are one, solved the leakage problem of pump.
The technological scheme that adopts
Oil-immersed pump mainly is made up of pump impeller, stator, motor stator, rotor, pump neck, pump head, fore bearing support, rear bearing rack, sleeve, motor outgoing cable.Rotor is arranged in the chamber of motor stator, rear bearing rack is fixed on the rear end of motor stator, which is provided with a plurality of inlet openings, fore bearing support and pump neck fixedly are located at the front end of motor stator, are respectively equipped with the liquid outlet opening of a plurality of mutual correspondences on fore bearing support and the pump neck.Be equiped with sliding bearing respectively on the rotor axis of electric at forward and backward bearing bracket place, and the forward and backward end of rotor axis of electric all is installed with thrust bearing.One end mill of rotor axis of electric has spline.Pump shaft is connected by spline with rotor axis of electric, pump impeller dress is not at the rear portion of pump shaft, stator is nested with the outside at pump impeller, the tail end of pump is equipped with and prevents that particle from entering the filter screen in the pump chamber, sleeve is nested with on motor stator, and is combined to form a liquid guiding cavity with screen holder and pump neck, and pump head is fixed on the pump neck, be provided with the liquid outlet channel that is connected with liquid guiding cavity in the pump head, its front end is provided with liquid outlet.The motor outgoing cable is connected with socket in the pump neck by pump head.Socket is connected by lead with rotor.
Major advantage of the present invention:
(1) motor and pump are one, and volume is little, in light weight;
(2) there is not leakage;
(3) easy for installation, and do not take up space;
(4) owing in motor and all potential liquid of pump, the motor good cooling results;
(5) motor and pump adopt the anticorrosive material manufacturing, can anti-various corrosive liquids.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.Fig. 2 is the structural representation of rear bearing rack of the present invention.
(5) specific embodiment
