Abstract
The utility model relates to an electric heating device, and in particular relates to the electric heating device for an oil well pipeline. The technical scheme is that the electric heating device for the oil well pipeline comprises an oil conveying pipe, an electric heating pipe, heating pieces, a temperature sensor, a conductive wire, a power supply protector, a frequency-variable adjustment power supply and an alarm, wherein the electric heating pipe is fixed outside the oil conveying pipe; a plurality of heating pieces are arranged in the electric heating pipe; the temperature sensor is arranged between the oil conveying pipe and the electric heating pipe; the temperature sensor is connected with the alarm; the electric heating pipe is connected with the frequency-variable adjustment power supply through the conductive wire; the power supply protector is arranged on the conductive wire. The electric heating device for the oil well pipeline has the following benefits: the electric heating device for the oil well pipeline has the advantages of high thermal efficiency, and convenience in assembling and disassembling, and can be widely applied to various pipeline heating occasions; electric heating can be realized by the frequency-variable adjustment power supply, so that electric energy is effectively saved and the production cost is reduced.
Description
One, technical field
The utility model relates to a kind of Electric heating appliance, particularly a kind of oil country tubular good Electric heating appliance.
Two, background technique
In the course of conveying of crude oil in transport pipe, variation due to ambient temperature, bring the variation of crude oil oil temperature, after oil temperature declines, the viscosity rise of crude oil, affects crude oil and flows ducted, especially winter, often there is frozen block booster in the oil transport pipeline in the north, affects oil transportation amount, affects the normal production of pumping well when serious.Electric heating with its have the thermal efficiency high, pollution-free, be easy to the advantage of controlling and by pay attention to day by day, conventional Electric heating lacks necessary watch-dog, need to realize by manual control stopping heating, cause waste of energy large, cause cost of production increase.
Three, summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil country tubular good Electric heating appliance is provided.
Its technological scheme is: comprise transport pipe, electric heating tube, heater band, temperature transducer, wire, power supply protector, variable frequency adjustment power supply, alarm; the external stability electric heating tube of transport pipe; the inside of described electric heating tube is provided with many group heater bands; between transport pipe and electric heating tube, be provided with temperature transducer; described temperature transducer connects alarm; electric heating tube connects variable frequency adjustment power supply by wire, and described wire is provided with power supply protector.
The outside of described electric heating tube is provided with thermal insulation layer.
The beneficial effects of the utility model are: it is high that this device has the thermal efficiency, and the convenient advantage of installing, dismantling, and are widely used in various pipeline heating occasions, by variable frequency adjustment power supply, can automatically realize electric heating, have effectively saved electric energy, have reduced cost of production.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: transport pipe 1, electric heating tube 2, heater band 3, temperature transducer 4, wire 5, power supply protector 6, variable frequency adjustment power supply 7, alarm 8, thermal insulation layer 9.
Five, embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises transport pipe 1, electric heating tube 2, heater band 3, temperature transducer 4, wire 5, power supply protector 6, variable frequency adjustment power supply 7, alarm 8, the external stability electric heating tube 2 of transport pipe 1, the inside of described electric heating tube 2 is provided with many group heater bands 3, between transport pipe 1 and electric heating tube 2, be provided with temperature transducer 4, described temperature transducer 4 connects alarm 8, electric heating tube 2 connects variable frequency adjustment power supply 7 by wire 5, and described wire 5 is provided with power supply protector 6; The outside of described electric heating tube 2 is provided with thermal insulation layer 9.
