Abstract
The utility model discloses a submerged pump with a hydrophobic electric motor, which is used to draw and such water. A water inlet chamber is arranged between the pump body and the electric motor, and a water outlet is arranged on the side face of the pump body. The working position of the submerged pump is that the pump body faces the direction of the water bottom and the electric motor faces the direction of the water surface. The utility model utilizes the water inlet chamber in the middle position and the water outlet in the side position to avoid the action form the pressure of the lift of the pump to the seal component of the electric motor, and also utilizes the characteristics of the two mediums of the water liquid and the oil liquid to select the working position with the pump body on the lower part and the electric motor on the upper part, realizing the active electric motor hydrophobic type protection. Besides, the utility model has the advantages of simple structure, convenient use, good waterproof performance, and long service life, and seal components are not easy to be damaged.
Description
The utility model relates to a kind of submersible pump, the hydrophobic submersible pump of particularly a kind of motor.
Existing all kinds of submersible pump, its working position adopt the structural type of the pump housing towards the bottom mostly, and during use, water liquid enters motor easily, and the heat radiation fluid in the motor overflows easily, its unreasonable structure, and poor sealing performance, working life is short; Though the submersible pump that has adopts the pump housing towards the water-bed and motor structural type towards the water surface, but intake chamber is at the end of the pump housing towards the bottom, and motor seal spare should bear diving depth hydraulic pressure, again the lift pressure of bearing pump machine, its unreasonable structure, sealing effect is poor; Chinese patent application 89205821.8 and 92219205.7 has proposed a kind of Submerged Motor Pumps and shielding Submerged Motor Pumps respectively, basic skills all is to increase the motor seal layer and adopt epoxy resin integral cladding electric motor for pump, its sealing protection mode is passive protection, and they have complex structure and the not high shortcoming of sealability.
The purpose of this utility model is to provide a kind of motor hydrophobic submersible pump, and it can simplify pump machine structure effectively, improves the motor seal performance reliably, greatly prolongs pump machine working life.
The purpose of this utility model is achieved in that between the pump housing 2 and motor 1 intake chamber 6 is set, and the side of the pump housing 2 sets out the mouth of a river 8, and the structure of this neutral position intake chamber 6 and side position water outlet 8 makes pump machine lift pressure can not act on motor seal spare; The working position of this submersible pump is the pump housing 2 towards water-bed and motor 1 towards the water surface simultaneously, according to the fluid principle lighter than water liquid, heat transmission transformer oil 3 in the motor 1 can not sunk and overflow, thereby effectively utilized environment and dielectric property, realize the active hydrophobic protective of motor 1 sealing case 4 and Sealing 5.
The utility model is because be provided with intake chamber between the employing pump housing and the motor, so avoided the pressure effect of pump machine lift pressure to the motor seal layer; Simultaneously owing to adopt the structural type of side position water outlet, thus impurity reduced in the water liquid to the infringement of Sealing, in addition owing to adopt the pump housing towards water-bed and motor pump machine working position, so improved the water-proof performance of motor effectively towards the water surface; The utility model also has simple in structure, and is easy to use; Sealing is difficult for advantage impaired and that service life is long.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the hydrophobic submersible pump structural representation of motor that the utility model proposes, Fig. 1 double as specification digest accompanying drawing.
Among the figure: 1, motor, 2, the pump housing, 3, transformer oil, 4, sealing case, 5, Sealing, 6, intake chamber, 7, impeller, 8, water outlet, 9, support, 10, electric wire.
During use, this submersible pump is put into the bottom, support 9 is placed on the water-bed plane, perhaps this submersible pump is suspended in the water, make the pump housing 2 towards water-bed direction, motor 1 is towards water surface direction, electric wire 10 is connected with power supply, starting electrical machinery 1, the pump housing 2 beginning pump suction liquid, the intake chamber 6 of water liquid between the motor 1 and the pump housing 2 sucks, and pumps through water outlet 8 then.In pump suction process, because the working position of pump machine is a motor 1 towards the water surface and the pump housing 2 towards the bottom; Thereby the heat transmission transformer oil 3 in the motor 1 can not sink to overflowing through sealing case 4 and Sealing 5: simultaneously, the position of intake chamber 6 can not make the effect of Sealing 5 and sealing case 4 bearing pump machine lift pressure yet, and the impurity in the water is because the effect of gravity, can not make Sealing 5 and sealing case 4 impaired, thereby greatly improved the water-proof performance of motor 1, the Sealing 5 of motor 1 and the working environment state of sealing case 4 have been improved, and effectively utilized the characteristic of oil, improved the hydrophobic type active barrier propterty of motor 1 reliably with the water two media.
