Hydraulic press noise problem solved

The noise problem of hydraulic press has always been a headache for everyone. As soon as we walked into the factory, the noise of the machine made us unbearable. Below, I would like to introduce some ways to solve the noise problem.

① Reduce sound source noise

1. Transform the production process and select low noise hydraulic press

2. Improve machining and assembly accuracy to reduce noise caused by mechanical vibration and friction.

3. Reduce the pressure difference and flow rate for high pressure and high speed airflow, or change the shape of the airflow nozzle.

② Control in transit

1. Reasonable design in the overall layout. When arranging the graphic design of factories and mines, the main noise source workshop or device should be far away from the workshop, laboratory, office, etc., which requires quiet, or the high-noise equipment should be set as far as possible to facilitate control.

2. The use of additional barriers to prevent noise transmission, or the use of natural terrain such as mountains, slopes, woods, bushes or tall buildings or additional structures that are not afraid of noise. 3. Use the directional characteristics of the sound source to control the noise. For example, the pressure cooker exhaust steam, blast furnace ventilation, oxygen generator exhaust and other exhaust outlets towards the wilderness or sky to reduce the impact on the environment.

③ Protection of the recipient

1. Carry out personal protection for workers, such as wearing earplugs, earmuffs, helmets and other anti-noise supplies.

2. Take worker rotation operation to shorten the working time of workers entering the high noise environment.
