3. Care and Maintenance of ZDR-0.5 Electric and Steam Heating Calorifier
(1) The temperature regulating valve should be installed on horizontal pipeline vertically. The arrow direction on valve should be consistent with the flow direction of medium. Keep a certain space for easy maintenance. There should be check valve and pressure gauge at the front and back of temperature regulating valve. The temperature regulating valve should be cleaned regularly. The pipeline which is used to install temperature regulating valve should be clean. There can’t be any sundries such as iron filings in it. It is needed to implement rust removal flushing before installing pipeline and temperature regulating valve.
Open the check valve at the front and back of temperature regulating valve to make the temperature regulating valve work normally. If the water temperature is lower than the higher limit of needed temperature, the regulating valve is opened. At this time, the pressure gauge at the back of valve will return to null point (perhaps the temperature will rise several degrees when there is no temperature outputted due to thermal inertia). It means it fits the requirements. If the water temperature can’t reach or has exceeded the control limit of regulating valve, please adjust according to the instruction book of temperature regulating valve.
(2) The WTZK-50-C marine pressure type temperature controller should be installed on instrument panel vertically. It is strictly forbidden to stir with hands or tools. The Temperature detection layer should be immersed in water completely. Don’t impact and compress the capillary. The bending radius can't be shorter than 50mm. It is needed to fix the capillary with clip every 300mm to ensure the safety.
(3) During the using of electric heater, if there is scale or carbon deposition on pipe, it is needed to use after cleaning so as to avoid affecting the service life and efficiency of electric element. If it is without of using for a long time, When the cold insulation resistance is lower than 1MΩ, it can be cured in the oven of 200℃ until returning to normal.
(4) Remove and clean the water tank regularly. After cleaning and brushing the inner wall, determine whether repaint according to flaking condition of painting. Repaint the out surface with anti-corrosive paint, meanwhile, replace wearing parts. After the spare parts are dry, reassemble it.
4. All kinds class certificate of ZDR-0.5 Electric and Steam Heating Calorifier can be supply.
