Reduce sound source noise
1. Transform the production process and select servo hydraulic press machines. 2. Improve machining and assembly accuracy to reduce noise generated by mechanical vibration and friction. 3. For high-pressure and high-speed airflow, the pressure difference and flow rate should be reduced, or the shape of the airflow nozzle should be changed.
Manipulate on the way
1. Reasonable planning in the overall layout. When arranging the floor plan of factories and mines, the main noise source workshops or hydraulic press machine should be kept away from workshops, laboratories, offices, etc. that require quietness, or high-noise equipment should be concentrated as much as possible to facilitate control. 2. Use additional barriers to block noise transmission, or use natural terrain such as hills, soil slopes, woods, grass, or huge buildings or additional structures that are not afraid of noise. 3. Use the directional characteristics of the sound source to manipulate the noise. For example, the high-pressure boiler exhaust, blast furnace exhaust, oxygen generator exhaust and other exhaust outlets are directed to the field or sky to reduce the impact on the environment.
Protection for the operator
1. Personal protection for workers, such as wearing earplugs, earmuffs, helmets and other anti-noise products. 2. Adopt operater rotation to shorten the working time of workers entering a high-noise environment.
All of our hydraulic press machines are custom servo hydraulic press machine with low noise and high precision advantages, if you need high quality hydraulic press machine, welcome to contact us.
