Abstract
The utility model discloses a thermostatic heating band for an oil conveying pipeline, which comprises an insulation layer. The utility model is characterized in that a heat generation layer of conductive rubber is arranged in the insulation layer. Both sides of the heat generation layer of the conductive rubber are connected with conducting wires. The utility model has the advantages of simple structure, quick heating, high heating efficiency, power consumption saving, long service life, etc. and can keep the constant temperature of the oil conveying pipe at 50 DEG C or so. The flowability of crude oil at a low temperature is ensured.
Description
Technical field
The utility model relates to a kind of heater, particularly a kind of heated at constant temperature band that is used for the oil pipeline road.
Background technique
After adopting crude oil from the down-hole, deliver to oil tank or store oil master station by oil transport pipeline.Cross when low when temperature, the oil in the oil transport pipeline freezes easily, and stickiness increases, and influences the normal conveying of crude oil.Common way will be provided with the oil transport pipeline heat exchanger with the crude oil temperature raising in the pipeline.Useful steam of existing oil transport pipeline heat exchanger or hot water heat up to pipeline, and its deficiency is that the thermal efficiency is low, wastes energy; Also useful electric heating wire heats to pipeline, and its deficiency is that the thermal efficiency is low, and the life-span is short, temperature control difficulty.The patent No. is CN01215604, denomination of invention discloses a kind of heater oil transport pipeline that has for the Chinese patent of " oil transport pipeline heat exchanger ", it comprises housing and is positioned at the transport pipe of housing, in housing, be coated with heating equipment on the outer wall of transport pipe, be coated with the ring packing interlayer made from Heat Conduction Material in the transport pipe outer wall, be filled with heat-conducting medium in the ring packing interlayer, ring packing interlayer outer wall is coated with inner insulating layer and external insulation layer, accompany electric heating film between the inside and outside isolation layer, electric heating film is connected with power supply by lead-in wire.Its working principle is: after being clipped in the electric heating film energising in the isolation layer, heat the heat-conducting medium in the annular Sealed sandwich, heat-conducting medium to the oil transportation tube wall, makes the crude oil of the oil transport pipeline of flowing through improve temperature heat transfer.Its deficiency is, complex structure, the thermal efficiency are not high, and power consumption is big, and can not accomplish constant temperature.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of novel pipeline heating tape is provided, and has thermal efficiency height, and quick heating is energy-conservation, the long service life advantage.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of oil transport pipeline heated at constant temperature band comprises isolation layer, it is characterized in that: the conductive rubber heating layer is arranged in described isolation layer, be connected with lead at described conductive rubber heating layer dual-side, described lead prolongs along conductive rubber heating layer dual-side.
For optimizing technique scheme, the measure of being taked also comprises:
The resistance value of described conductive rubber heating layer is 10-20 kilo-ohm.
Because the utility model taked above-mentioned technical measures, compared with prior art have simple in structure, quick heating, the flowability of following crude oil.
Description of drawings
Fig. 1 is the utility model embodiment's a sectional structure schematic representation;
Fig. 2 is the cross-sectional structure schematic representation of Fig. 1;
Fig. 3 is the mounting structure schematic representation of the utility model on oil transport pipeline.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
With reference to Fig. 1, the utility model comprises isolation layer 2, and conductive rubber heating layer 1 is arranged in isolation layer 2.Conductive rubber heating layer 1 can adopt conductive silicon rubber, also can adopt other conductive rubbers.Be connected with lead 3 at conductive rubber heating layer 1 dual-side.Lead 3 prolongs along conductive rubber heating layer 1 dual-side.The resistance value of conductive rubber heating layer 1 is 10 kilo-ohms.With reference to Fig. 2, during use, the winding of this heated at constant temperature band is coated on the transport pipe 4.After the energising, when external temperature rose, conductive rubber resistance can increase voluntarily, and can reduce by the electric current of conductive rubber, thereby the heat that conductive rubber is sent reduces.Otherwise if external temperature reduces, the resistance of conductive rubber can reduce voluntarily, and the electric current that flows through conductive rubber will increase, thereby the conductive rubber heating temperature is raise, and transport pipe constant temperature has guaranteed the flowability of crude oil at low temperatures about 50 ℃.
The utility model also can be used for other pipelines that need be incubated.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
