Does an LNG export low-pressure pump require a vibration detection device?

Everything shall be in accordance with the equipment provided by the manufacturer; what is necessary will certainly be installed, while nothing unnecessary will be added unnecessarily. Such equipment must be produced by qualified manufacturers that hold certifications issued by the relevant safety supervision authorities. Don’t worry, someone will think of it for you: lol

Just follow the design requirements for this; if they specify something to be installed, then install it, and if not, there’s no need to install it

Another person obsessed with standards and regulations – **without any standards or guidelines for everything, they immediately feel as if they don’t know how to carry out tasks. Obsession with standards brings success; obsession with standards also brings failure. He is simply the Kong Yiji of the new era. The casual chat is over. Answering your question: There is no need to install a dedicated vibration monitoring device. It’s likely that the idea came from the desire to avoid the hassle of having to go to the site and use handheld instruments for testing in the future. By installing a fixed monitoring device equipped with sensors, one can monitor things from the office at any time – it’s convenient and comfortable, and a database can also be generated automatically. That’s probably what was behind this plan With such a big scale, will the person who’s funding it (the boss) agree? If you really want to worry about the equipment, it’s better to focus on mobile handheld devices – be more active with your legs and hands, and it won’t be that exhausting.

The current mainstream for LNG pumps are cryogenic submersible pumps; what handheld instruments do you use to measure them? Vibration monitoring is recommended for submersible pumps. Otherwise, failing to detect and address issues in advance due to malfunctions will lead to bigger problems, resulting in losing more than what was lost in the first place

Vibration probes for the LNG submersible pumps used for external transportation are standard equipment; you can choose not to use them, but it is recommended to use them. It can effectively monitor the operating status of the pump!

They all need to be configured, right? Usually two probes.

The LNG submersible pump is primarily used for balancing; the vibration detection device is only used to collect data in cases of imbalance, and it is optional
