In the operation of modern power plants, the reliability and environmental protection of equipment are particularly important. As one of the core power equipment widely used in power plants, electric motors undoubtedly play an indispensable role. However, traditional motors may generate large noise due to long-term operation, and the pump system is prone to frequent wear of seals due to motor vibration, or loose foundation due to vibration problems, which in turn causes safety accidents.

How to solve this problem has become an important topic in equipment selection and optimization. This article will take the YBX3-250M-4 55kW three-phase asynchronous motor as an example to deeply explore its noise and vibration control methods and advantages in power plants.

1. Overview of YBX3 series motors: Dual guarantee of efficiency and performance

YBX3 series three-phase asynchronous motors are highly favored high-efficiency and energy-saving motors on the market. As a reliable drive source, the YBX3-250M-4 three-phase asynchronous motor has greatly extended the maintenance cycle of the equipment and saved maintenance costs through its low-noise fan and high-rigidity structure, precise dynamic balancing technology and vibration isolation design.

The rated power of the YBX3-250M-4 model motor is 55kW, with a four-pole design and moderate speed, which is very suitable for application scenarios such as pump equipment, ventilators and conveying equipment in power plants.

2. Special requirements for noise and vibration in the power plant environment

As an important place for energy production, power plants have strict requirements on the operating environment and equipment performance, especially noise control and vibration control. Long-term high noise will not only affect the health of workers, but also make it difficult to monitor the operating status of the equipment, affecting the timeliness of equipment operation and maintenance. Excessive vibration will shorten the service life of the motor and auxiliary equipment, and even cause safety accidents; high vibration may lead to increased energy loss and reduced operating efficiency.

Therefore, power plants need motor equipment to provide sufficient power and remain “quiet” and “stable” during operation, and YBX3-250M-4 three-phase asynchronous motor is particularly outstanding in this regard.

3. Analysis of noise and vibration control technology of YBX3-250M-4

I. Noise control technology

YBX3-250M-4 motor adopts the following technical means in noise control:

Optimized air duct design: The ventilation system of the motor has been accurately calculated and experimentally verified, and adopts low-noise axial flow fan and streamlined wind shield design, which effectively reduces aerodynamic noise during operation.

High-precision processing technology: Through advanced CNC processing technology, high-precision assembly of parts is ensured, and mechanical noise caused by misalignment of parts or excessive surface roughness is reduced.

Electromagnetic noise suppression: The stator and rotor cores of the motor are made of high-quality silicon steel sheets, and are precisely stacked, and the electromagnetic design is optimized to reduce electromagnetic oscillation and noise caused by changes in the magnetic circuit.

II. Vibration control technology

Three-phase asynchronous motor YBX3-250M-4′s performance in vibration control is also impressive:

Dynamic balancing calibration: The motor rotor undergoes a strict dynamic balancing test before assembly to ensure that it rotates smoothly during operation and reduce vibration sources.

Vibration reduction support design: adopt high-rigidity motor base and anti-vibration rubber pad installation method to reduce vibration transmission between the motor and the foundation.

Fully enclosed structure: YBX3 series adopts a fully enclosed structure to effectively prevent foreign particles and liquids from entering the body and avoid unbalanced vibration caused by pollution.

Operation monitoring system: Vibration sensors and online monitoring devices can be selected to monitor motor vibration in real time, and problems can be discovered and solved in time.

As a high-efficiency, low-noise, and low-vibration motor equipment, YBX3-250M-4 three-phase asynchronous motor not only meets the demanding requirements of power plants in terms of performance, but also provides advanced solutions for industrial noise and vibration control.
