The noise generated by the fully automatic high pressure steam sterilizer during operation will not only have adverse effects on the physical and mental health of the operator, but may also interfere with the surrounding working environment. Therefore, it is of great significance to study its noise control methods and acoustic performance improvement.
First of all, one of the main sources of noise is the steam generation and discharge process. When water is heated and converted into steam, it will produce strong airflow impact and vibration, as well as the friction sound of steam and the pipe wall when it flows at high speed in the pipeline. In addition, when the exhaust valve discharges excess steam, it will also produce a large noise due to the instantaneous release of gas. These noises usually have a higher frequency and a larger sound pressure level, and are an important part of the noise of the fully automatic high pressure steam sterilizer.
In order to reduce the noise in the steam generation and discharge links, a variety of measures can be taken. For example, in the design of the steam generator, the heating structure is optimized so that water can be converted into steam more evenly and smoothly, reducing the impact noise caused by local intense boiling. At the same time, a muffler is installed on the steam pipeline. The sound-absorbing material and special structure inside the muffler can effectively absorb and reflect sound waves and reduce the propagation of steam flow noise. For the exhaust valve, throttling and pressure reduction can be used to gradually release the steam pressure and reduce the noise peak at the moment of exhaust.
The operation of the mechanical parts of the equipment is also one of the sources of noise. For example, pumps, motors and other parts will generate vibration and friction noise during operation. For these parts, shock-absorbing measures can be adopted, such as installing rubber shock-absorbing pads, spring shock absorbers, etc., to reduce the transmission of vibration to the equipment casing and the surrounding environment. At the same time, mechanical parts should be lubricated and maintained regularly to ensure smooth operation and reduce the generation of friction noise.
The shell design of the fully automatic high-pressure steam sterilizer also has a certain impact on the acoustic performance. Using sound insulation materials to make the shell, or adding a sound-absorbing layer inside the shell, can effectively block and absorb the noise generated inside and prevent it from propagating outward. In addition, the reasonable design of the shape and structure of the shell to avoid the formation of a resonance cavity can also help reduce the radiation of noise.
In the installation and use stages, choosing a suitable site and installation method can also play a certain role in noise reduction. Install the fully automatic high-pressure steam sterilizer away from crowded areas and ensure that it is installed smoothly to avoid additional noise caused by equipment shaking. At the same time, a soundproof barrier is set up around the equipment to further isolate the spread of noise.
In addition, regular acoustic performance testing and evaluation of fully automatic high pressure steam sterilizers is also essential. Through professional acoustic testing instruments, the noise level of the equipment under different working conditions is measured, and the frequency characteristics and propagation path of the noise are analyzed, so as to take more effective noise reduction measures in a targeted manner, continuously optimize the acoustic performance of the equipment, create a relatively quiet and comfortable working environment for operators, and improve the overall quality and market competitiveness of the equipment.
