The medium-pressure feed water pump stops suddenly – how should the operator respond? Is it necessary to stop?
Thread Content
I would like to ask the teachers: In a sulfuric acid production plant, under normal operating conditions, if the medium-pressure feed water pump suddenly stops working, how should the operators respond? What are the other changes or precautions regarding the device? Is it necessary to stop? Thank you!
Since it’s out of service, it’s no longer in operation. It is common for important equipment to be equipped with a backup pump. In the event of a power outage, a backup pump driven by an internal combustion engine or a backup high-level water storage tower must be available as a contingency measure. In the case of normal supply, simply start the backup pump as quickly as possible.
Stop for inspection; do not move on until the cause of the accident is determined
An emergency stop is necessary; there should be a interlocked stop mechanism
Hehe, it’s just about starting one pump! There’s no need to be so nervous! When this situation occurs, take immediate action: 1. Prepare for an emergency stop, and closely monitor the liquid level in the drum as well as the temperature of the economizer; if there are any abnormalities in temperature or liquid level and the backup pump isn’t ready in time, shut down the entire system. 2. Such critical pumps usually come in pairs, so activate the backup pump right away!
There are safety interlocks for the liquid level; these interlocks cannot be disabled. If the liquid level reaches a critical level, the system will shut down automatically. In the event of a water supply interruption, the system can be restored to normal operation, so there’s no need to shut it down
