太陽能輔熱管道加熱

主要結(jié)構(gòu)及工作原理

The main structure and working principle

管道電加熱器結(jié)構(gòu)electric heater pipe structure

管道電加熱器是由多支管狀電加熱元件、筒體、導(dǎo)流板等幾部分組成，管狀電熱元件是在金屬管內(nèi)放入高溫電阻絲，在空隙部分緊密地填入具有良好絕緣性和導(dǎo)熱性能的結(jié)晶氧化鎂粉，采用管狀電熱元件做發(fā)熱體，具有結(jié)構(gòu)先進，熱效率高，機械強度好，耐腐、耐磨等特點。筒體內(nèi)安裝了導(dǎo)流隔板，能使介質(zhì)在流通時受熱均勻。

Tube electric heater is made up of highly branched tubular electric heating element, barrel, guide plate of several parts, such as tubular electric heating element is in the metal tube in the heat resistance wire, the void part closely to fill in the crystallization have good insulation and thermal conductivity of magnesium oxide powder, tubular electric heating element is applied to make heating element, has the advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance, abrasion resistance and other characteristics. Cylinder body installed diversion clapboard, can make the medium in circulation when heated evenly.

    安裝The installation

控制柜應(yīng)安裝在干燥通風，便于操作的地方。管道電加熱器外殼、控制柜外殼應(yīng)可靠接地，管道電加熱器應(yīng)水平安裝，底座螺母要擰緊使其穩(wěn)固。

本體與外接管道安裝時，應(yīng)注意進出口方向。管道電加熱器在使用前應(yīng)測量電源接入端子與金屬外殼絕緣電阻不得低于2MΩ，使用環(huán)境相對濕度不大于85%。電源線的出、入端應(yīng)牢固可靠，不得松動。

Control cabinet shall be installed in a dry and ventilated, easy to operation. Electric heater pipe shell, control cabinet shell should be reliable grounding, tube electric heater should be installed, base nut to tighten the firm.

Ontology and the external pipe installation, should pay attention to the direction of the import and export.Electric heater pipe before use should be measured power access terminal and metal exterior insulation resistance shall be not less than 2 m 惟, use environment relative humidity is not more than 85%. The power cord, into the end should be solid and reliable, and shall not be loose.
