Whether the boiler can be safe and stable operation and the boiler feed pump has a great relationship, with the modern automation technology in the boiler feed pump in the promotion and application of modern boiler liquid level automatic adjustment system has become the key to safe and stable operation. The promotion and application of modern technology does not reduce the boiler feed pump failure.
Failure analysis of modern large-scale boiler feed pump system consists of multiple feed pumps, starting from two to three main feed pump, one or two electric water pump as a backup or auxiliary. This feed pump configuration is conducive to the failure of the feed pump main engine system or can not meet the boiler operation needs, start spare water supply pump system to add enough to avoid the pump failure caused by the boiler shutdown. Common boiler feed pump failure is mainly concentrated in the lubricating oil system, shelter system, speed control system, auxiliary motor overheating and inadequate flow and so on several aspects. Through the scientific analysis and troubleshooting reasons to exclude and solve the boiler feed pump failure basis, only for the cause of the malfunction to be eliminated in order to avoid the recurrence of the same type of failure. The following describes the causes and exclusions of different fault types.
The stable operation of the boiler feed pump is the basis of the stable operation of the boiler, is an important part of the modern boiler level control system, once the feed pump failure will seriously endanger the operation of the boiler safety, serious will lead to major accidents. Therefore, strengthening the boiler system to the daily maintenance and repair of water pumps, boiler maintenance has become an important modern work.
