Abstract
The utility model discloses an automatic viscosity reduction cooling device of a transmission of a pumping unit. The automatic viscosity reduction cooling device comprises a transmission shell, a semiconductor cooling and heating piece, a temperature sensor and a controller. The semiconductor cooling and heating piece is arranged on the side face of the inner wall of the transmission shell, a protection layer is arranged on the outer side of the semiconductor cooling and heating piece, and the temperature sensor is arranged in the middle of one side of the inner wall of the transmission shell. The semiconductor cooling and heating piece is electrically connected with the output end of the controller, the input end of the controller is electrically connected with the temperature sensor, and a power terminal is connected to the controller. The automatic viscosity reduction cooling device is reasonable in design, simple in structure and convenient to install and use. Lubricating oil in the transmission can be automatically heated or cooled according to the temperature of the transmission when the automatic viscosity reduction cooling device is used in cold winter or hot summer, the transmission is effectively prevented from being damaged due to the fact that lubricating oil in the transmission is too viscous or too hot, the frequency of halt stop well transmission maintenance is greatly reduced, and the oil extraction yield and normal work are guaranteed.

Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
With reference to Fig. 1, the automatic viscosity reduction cooling unit of a kind of pumping unit gear shifting box, comprise gear box casing 1, semiconductor cooling backing 2, temperature transducer 3 and controller 4, described gear box casing 1 inwall side is provided with semiconductor cooling backing 2, semiconductor cooling backing 2 outsides are provided with protective coating 6, and gear box casing 1 inwall one middle side part is provided with temperature transducer 3; Described semiconductor cooling backing 2 is electrically connected to the output terminal of controller 4, and the input end of controller 4 is electrically connected to temperature transducer 3, is connected with power supply terminal 5 on controller 4.Wherein, described controller 4 comprises single chip machine controlling circuit 42 and power circuit 41, described temperature transducer 3 is connected with the input end of single chip machine controlling circuit 42, the output terminal of single chip machine controlling circuit 42 is connected with semiconductor cooling backing 2, the power end of single chip machine controlling circuit 42 is connected with the output terminal of power circuit 41, and the input end of power circuit 41 connects power supply terminal 5.Described power circuit 41 is AC/DC change-over circuit.
During operation, power supply terminal 5 is connected on the power supply of pumping-unit motor, when pumping unit gear shifting box temperature is too low while causing lubricant oil to be clamminess, temperature transducer 3 passes to signal the single chip machine controlling circuit 42 of controller 4, make its output forward power supply, now semiconductor cooling backing 2 presents heating outside, inner side refrigerating state, gives lubricant oil viscosity reduction; When pumping unit gear shifting box excess Temperature, temperature transducer 3 passes to signal the single chip machine controlling circuit 42 of controller 4, makes its output reverse electrical source, and now semiconductor cooling backing 2 presents refrigeration outside, inner side febrile state, to lubricant oil, lowers the temperature.
The utility model is reasonable in design, simple in structure, easy to install.It uses when cold weather and hot summer in the winter time; can automatically the lubricant oil in gearbox be heated or be lowered the temperature according to temp. of gear-shifting box; effectively stop the interior lubricant oil of gearbox because of the feeding-up or overheated mode of damaging phenomenon that causes; greatly reduce the number of times that stops well servicing gearbox, guaranteed output and the normal work of recovering the oil.
