What is the reason that the temperature difference between the inlet oil and the outlet oil in thermal oil heater exceeds the given value?
(Question details) Specific performance:
The temperature difference between the inlet oil and the outlet oil temperature of the boiler exceeds the given value.
Answer:Cause of failure:
(1) The oil supply of the heat oil circulating pump is insufficient.
(2) The boiler operates overload.
(3) Thermal oil metamorphism.
(4) The boiler does not match the heating equipment.
(5) Bad insulation effect.
(6) There is gas or steam in the thermal oil.
Troubleshooting:
(1) Remove the faults of oil pump and pipeline.
(2) Operate at normal load.
(3) Change new oil.
(4) Choose proper boiler.
(5) Check the insulation layer and repair the loopholes.
(6) Remove air or steam.
ZOZEN pays much attention to boiler furnace insulation also, the inside is made of high quality insulation material, external use of stainless steel plate, which can maximumly reduce heat loss and improve the operating environment.
