供热设备的合理安装及运行故障的消除

对采暖供热系统中最容易出现的问题进行了理论分析 ,提出了相应的改进措施。热水循环系统中的空气是最有害的因素之一 ,为了有效地排除空气 ,必须进行正确的注水操作和集气罐的合理安装。对于因不合理的安装方式而造成循环泵的抽空现象 (即水泵的吸入口呈空气和水的混合状态 ,使水泵达不到应有的额定流量 ) ,实施了改进。另外还介绍了利用“压差测试法”,确定除污器应该进行除污的时间。

Reasonable Installation of Heat Supply Device and Elimination of Run Trouble

Theoretical analysis is made about the most common problems which occur in heating and heat supply system.The corresponding improved methods are introduced.The air in hot water cycle system is one of the most harmful factors.The correct affusion operation and reasonable installation of collecting gas jar are introduced in order to eliminate air effectively.The improved methods are given for the empty pumping phenomenon of the cycle pump resulted by the unreasonable installation,namely,when the suction entrance of the water pump is in the mixing state of air and water,the pump cannot reach the rating flow.The test method with pressure difference is introduced,which is used to test when the dirty clean device has to clean the dirt.
