Description
Technical field
The utility model relates to eccentrie helical totorpump screw rod.
Background technique
Screw pump is volume type rotor pump, and it is to rely on the volume-variation of the Seal cage being formed by screw and bushing to suck and discharge liquid.In some occasion, as flowing fluid ratio during compared with thickness, when particularly the stickiness temperature influence of liquid is larger, in order to ensure that screw pump normally carries this liquid, need in screw pump, carry out heating and thermal insulation to this liquid.
Model utility content
The purpose of this utility model is to provide a kind of eccentrie helical totorpump screw rod, and its inside is provided with the passage of conduction oil, by input conduction oil, can carry out heating and thermal insulation to heat conduction ring, and then in screw pump, liquid be carried out to heating and thermal insulation.
For achieving the above object, the technical solution of the utility model is a kind of eccentrie helical totorpump screw rod of design, comprises spirality screw rod main body, and the sectional shape of described screw rod main body is circular;
Described screw rod main body arranges some toroidal cavities along width interval such as its bearing of trends, is provided with ring heat conduction ring in described toroidal cavity, and the outer circumferential face of described heat conduction ring and screw rod main body outer circumferential face maintain an equal level;
In described screw rod main body, be provided with and heat conduction ring ring the first cavity one to one, the sectional shape of described the first cavity is circular; Described ring the first cavity with corresponding heat conduction ring in same plane;
The inner peripheral surface of each heat conduction ring is circumferentially evenly equipped with some heat conduction nails; Heat conduction nail on same heat conduction ring all inserts in the first cavity corresponding with this heat conduction ring;
In described screw rod main body, be also provided with and screw rod main body the second cavity of spiral extension in the same way, the sectional shape of described the second cavity is circular;
Each the first cavity connects with the second cavity by some the 3rd cavitys that arrange in screw rod main body, and described the 3rd cavity is cylindrical;
The two ends of described screw rod main body are respectively equipped with the conduction oil inlet opening connecting with the second cavity.
By the setting of the first cavity, the second cavity, some the 3rd cavitys, make the utility model eccentrie helical totorpump inside screw form the passage of conduction oil, by input conduction oil, can carry out heating and thermal insulation to the heat conduction nail inserting in the first cavity, and then heat conduction ring is carried out to homogeneous heating and insulation, and then in screw pump, liquid is carried out to homogeneous heating and insulation.
Preferably, the 3rd cavity being connected with same ring the first cavity is positioned at same plane, is convenient to the transmission of conduction oil, improves heating and thermal insulation effect.
Advantage of the present utility model and beneficial effect are: a kind of eccentrie helical totorpump screw rod is provided, and its inside is provided with the passage of conduction oil, by input conduction oil, can carry out heating and thermal insulation to heat conduction ring, and then in screw pump, liquid be carried out to heating and thermal insulation.
