How to solve the noise of hydraulic press

Many people know that when the hydraulic press works to suppress the product, the collision will produce noise. If people work in the noisy noise of the machine for a long time, it is bound to have an impact on people's hearing. For this reason, the research and development manufacturers of hydraulic press have been trying to find ways to reduce the noise of the machine and minimize the harm to workers while not reducing the working efficiency of the hydraulic press.

As one of the early R & D manufacturers of domestic hydraulic press, delishi hydraulic press R & D team has more than 20 years of R & D and production experience, and has been working hard to solve this problem for many years! At present, delis company covers an area of more than 78000 square meters, has more than 100 technicians for more than 10 years, has the ability to independently develop hydraulic software, and has cooperated with more than 50 top 500 enterprises in the world.

Let's take a look at delis hydraulic press and give suggestions:

1、 The sound source noise is reduced by using servo motor

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

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

3. For high-pressure and high-speed air flow, the pressure difference and flow rate should be reduced, or the shape of air flow nozzle should be changed.

2、 Control on the way

1. Reasonable design in the overall layout. In the plane design of factories and mines, the main noise source workshop or equipment should be far away from the workshop, laboratory, office, etc., which require quiet, or the high noise equipment should be concentrated as far as possible, so as to facilitate the control.

2. Use barriers to prevent noise transmission, or use natural terrain such as hills, soil slopes, trees, grass, or huge buildings or additional structures that are not afraid of noise.

3. Use directional characteristics of sound source to control noise, such as exhaust of high-pressure boiler, blast furnace, oxygen generator, etc., to face the wilderness or sky, so as to reduce the impact on the environment.

3、 Protection for operators of hydraulic press

1. Carry out personal protection for workers, such as wearing earplugs, earmuffs and helmets.

2. Workers should be rotated to shorten the working time of workers entering high noise environment.
