In recent years, due to the boiler feed pump failure caused the accident shut down the boiler uncommon, the reason is not a good grasp of equipment maintenance department reasons boiler feed pump failure occurs DG12-25 × 11 boiler feed pumps, boiler feed pumps text on daily maintenance and Troubleshooting a brief discussion, in order to provide more information to learn for equipment maintenance department. 0 Introduction boiler feed pump is related to the critical boiler boiler system safe and stable operation of the feed pump, is an important part of the design using modern automatic control technology and the formation of boiler automatic level adjustment system. At present, China has more than four hundred thousand units of boiler equipment, most of which are industrial enterprises in power plant boilers and boiler system for the residents of a small part of the baths and other commercial areas. Stable foundation to run the boiler pump is important to adjust the level of modern boiler system components in this section. Once the feed pump failure would seriously jeopardize the safe operation of the boiler, will also lead to severe major accidents. Therefore, strengthening the boiler feed pump system routine maintenance and repair, has become an important work of modern boiler maintenance department. Therefore, a multi-stage boiler feed pump boiler feed pump) _DG12-25 × 11 _ boiler feed pump boiler feed pumps provided by Anguo Shi Yuan Pumps Limited. Shi Yuan Yasukuni City Pump Co., Ltd.
