Auscultation is a commonly used method for diagnosing simple pump equipment. By listening to the sound emitted by the equipment when it is running, it is possible to determine whether the equipment has abnormal noise or noise. These abnormal noises can indicate hidden problems inside the device, such as loosening, impact, imbalance, etc.
An electronic stethoscope is a vibration accelerometer that converts and amplifies the vibration conditions of a device into an electrical signal. Workers can use headphones to monitor the vibrations of the running equipment, enabling qualitative measurement of sound. By measuring the signals at the same measurement point, at different times, at the same speed, and under the same working conditions, and comparing them, we can determine whether the equipment is faulty.
When there is a crisp and thin noise in the earphones, it means that the vibration frequency is high, and it is generally a local defect or microcrack in the relatively small size and relatively high strength parts. It's like the crisp sound that comes when you strike a small clock. When the earphones emit a dull and muffled noise, it means that the vibration frequency is low, and it is generally a large crack or defect in the relatively large size and relatively low strength parts. It's like the muffled sound of hitting a big drum. When the noise coming from the headphones is stronger than usual, it means that the fault is developing, and the louder the sound, the more serious the failure. It's like the sound of the gradual increase in volume that we hear in **. When the noise coming from the headphones is chaotic and intermittent, it means that a part or part is loose. It's like the irregular noise heard in **.
In conclusion, auscultation is a very practical method for troubleshooting pump equipment. By grasping the rhythm and rhythm of the equipment when it is operating normally, we can identify whether the equipment is experiencing abnormal noise and noise through the auditory function. Combined with the use of electronic stethoscopes, we can more accurately judge whether the equipment is faulty and take timely measures for repair and maintenance.
