安装及使用换热器特别注意事项蒸汽与水换热时，需先通水后通蒸汽；停机时，

Special precautions for installation and use of heat <br>exchangers When steam and water are used for heat exchange, you need to pass water first and then steam; when shutting down, stop the steam first and then stop the water; it is strictly forbidden to pass the steam first and the other side does not have water or the water does not circulate and dry. Water and water exchange heat. When the pipeline is filled with water, the pressure on both sides should rise alternately and gently. If it is not used for a long time, the heat exchanger should be drained; it is strictly forbidden to leave it idle for a long time without pressure on one side; to prevent internal icing caused by low temperature outside.

Precautions for installation and use of heat exchanger<br>During heat exchange between steam and water, water shall be supplied first and then steam; During shutdown, stop steam first and then water; It is forbidden to pass steam first, and there is no water on the other side or dry burning without circulating water. Heat exchange between water and water. When the pipeline is filled with water, the pressure on both sides shall rise alternately and gently. If it is not used for a long time, the heat exchanger shall be drained; It is forbidden to leave one side under pressure and the other side without pressure for a long time; Prevent internal freezing caused by external low temperature.

And special precautions for installing and using heat exchangers. When exchanging heat with water, it is necessary to pass water before passing steam; When stopping, stop the steam first and then stop the water; It is strictly forbidden to let the other side of the steam pass without water or dry burning without circulating water. When exchanging heat with water, when the pipeline is filled with water, the pressure on both sides should rise alternately and gently. For a long time, the heat exchanger should be emptied; It is forbidden to idle for a long time with pressure on one side and no pressure on the other; Prevent internal freezing caused by external low temperature.
