👩‍🔧Conversation Kickstarter Guide for Vibration Analysis

Hello and welcome to spiderAI™! We’re excited to have you here as you explore our cutting-edge conversational AI designed to help with vibration analysis. Our goal is to provide you with the most accurate and insightful diagnosis for your vibration issues through a friendly, helpful and assistive process.

To get started, spiderAI™ needs to understand your usecase in detail. The better you describe your case, the more effectively it can assist you. Follow the guide below to structure your case so spiderAI™ can work towards resolving your vibration challenges.

1. Describe your machine and the reason for analysis:

Start by telling us about your machine. What type of machine is it, what does it do, and what is its drive train configuration? Why are you concerned about it? Providing these details helps set the context.

Example: "I'm concerned about our main boiler feed pump. It's a 6-stage centrifugal pump driven by a 500 kW motor at 3600 RPM, connected through a flexible coupling. Our operators reported increased noise levels last week, and I've noticed a gradual rise in vibration readings over the past month."

2. Share your initial observations and measurements:

Next, share what you've observed so far. Have you noticed any unusual noises, changes in performance, or specific concerns? Also, include any preliminary measurements you’ve taken and what they indicate.

Example: "I took some preliminary readings at the pump's inboard bearing. The horizontal vibration at running speed is measuring 7.5 mm/s RMS, which is about double our normal levels. The vertical and axial readings are elevated too, but not as much."

3. Mention accessible parts and available analysis tools:

Tell us which parts of the machine you can access for further measurements. Also, mention the tools you have available for analysis.

Example: "I can access all bearings on both the pump and motor. We have a portable vibration analyzer that can do spectrum analysis and phase measurements."

4. Include any suspicions about the cause:

Based on your observations and measurements, do you have any suspicions about what might be causing the issue? Even if you’re not sure, sharing your thoughts can be helpful.

Example: "Given the symptoms and the fact that we recently overhauled the pump, I'm wondering if we might have an alignment issue. But I'm open to other possibilities."

5. State your objective clearly:

Finally, clarify what you hope to achieve with this analysis. What is your main objective? This will help guide the diagnostic process and ensure we address your primary concerns.

Example: "My goal is to identify the root cause of this increased vibration and noise. I need to determine if we can continue running the pump safely or if we need to schedule immediate maintenance."

Remember, the more context you provide, the better the analysis will be. Feel free to include any additional details you think might be relevant, such as recent maintenance activities or changes in operating conditions.

Once you have collected the details for the five steps, combine them into a single prompt as shown below:
