The application range of thermal oil furnaces is mjög wide, og þeir eru víða notað í hitun kerfi af ýmislegt varma olía ofnar

The thermal oil furnace heating system is based on relevant natural and technological sciences, combined with accumulated technical experience in production practice, to study and solve theoretical and practical problems in the development, design, manufacturing, installation, operation, and repair of various machinery. The development of various engineering fields requires the heating system of thermal oil furnaces to have corresponding development, and all require the necessary machinery provided by the thermal oil furnace heating system. The invention and improvement of certain machinery can lead to the emergence and development of new engineering technologies and industries. For example, the successful manufacturing of a large-scale power thermal oil furnace heating system led to the establishment of an electric heating thermal oil furnace system; The invention of locomotives led to the rise of railway engineering and the railway industry; The invention and progress of internal combustion engines, gas turbines, rocket engines, and the successful development of airplanes and spacecraft have led to the rise of aviation and aerospace industries; The development of high-pressure equipment has led to the success of many new types of synthetic chemical engineering, and so on.

Þetta veltur á á uppbyggingunni af the hitaranum. The tíðni breytir getur aðeins breyting tíðni af AC krafti, þar með breyting the snúningshraða af mótor og ná markmiðinu af breytingunni af úttakinu af af mótornum. Og síðan the hitari gerir ekki snúningur, tíðni umbreyting get ekki stjórnað upphitun hraði.

Það eru tvær einfaldar aðferðir:

1. Nota díóða hálf bylgja leiðrétting til að breyta the árangursríkt gildi af AC máttur % 2c ná markmið af breytinga upphitun máttur og upphitun hraði ; Þetta aðferð hefur the mest forrit% 2c og þess kostur er það hringrás er einfalt og auðvelt að starfa.

2. Voltage transformation, using a small transformer for voltage transformation, has the advantage of being adjustable in multiple levels, but the disadvantage is that the circuit structure is complex and the production cost is high.
