How To Stop Starter Motor Noise

Construction machinery is indispensable equipment in modern construction and industrial fields. Its powerful functions and efficiency have brought great convenience to people's production and life. However, with the widespread use of construction machinery, noise problems have gradually emerged. Especially the noise generated when starting the motor has brought certain troubles to the working environment and personnel health. In this article, MyMROmarts will explore effective ways to eliminate noise from construction machinery starter motors. The purpose is to provide some useful references for the construction machinery industry.

Analysis Of The Causes Of The Noise Of The Starter Motor

a. When the engine starter is running, due to high-frequency vibration, the mechanical structure will resonate, resulting in noise.

b. The starter motor transmits power to the various components of construction machinery through the transmission system, and the friction and collision in the transmission link will generate noise.

c. When the engine is started, the airflow of the intake and exhaust system flows rapidly, causing airflow noise.

d. The exhaust pipe may vibrate and resonate due to poor fixing or aging materials when the starter motor is running, resulting in noise.

Effective Way To Eliminate Starter Motor Noises

Set up a reasonable shock absorber around the starter motor of construction machinery. This can effectively reduce vibration transmission and reduce noise generation. Choose suitable shock-absorbing materials and structures, such as rubber pads, spring shock absorbers, etc. Isolate the starter motor from the mechanical body to reduce the probability of resonance. In addition, some key parts of construction machinery and equipment, such as the electric alternator and other diesel engine components, are sound-proofed. Such as adding sound insulation boards, sound insulation covers and other measures to effectively block the noise transmission path.

Optimize the design of the intake and exhaust systems, and use devices such as mufflers and buffer chambers to reduce airflow noise. Reasonably arrange the intake and exhaust passages to reduce the impact of airflow and the generation of eddy current noise. In addition, check and replace the exhaust pipe regularly to ensure that it is fixed reliably to avoid noise caused by vibration.

Regular maintenance of construction machinery is an important measure to eliminate the noise of the starter motor. Keep construction machinery and equipment in good condition, and regularly replace wearing and aging parts. Prevent loosening of the mechanical structure and increased vibration. In addition, keeping the engine oil clean and adding lubricating oil correctly can effectively reduce the friction noise of the transmission system. Finally, test that the starter motor is working properly. Whether it can drive the normal work of other heavy duty diesel parts and construction machinery equipment.

To sum up, eliminating the noise of the starter motor is an important task in the field of construction machinery. Through the use of sound insulation materials, optimized design, regular maintenance, and other methods. It can effectively reduce the noise level of the starter motor. In addition, the operator can also take some measures to reduce the impact of noise on personnel and the environment in actual operation.
