How to reduce noise of sound insulation wall with stainless steel perforated plate
Author:
Stainless steel perforated plate refers to the perforated mesh plate made of stainless steel. Stainless steel perforated plate has many advantages. The main advantages are: flat, smooth, beautiful, durable, and widely used.
The sound insulation wall is composed of various stainless steel perforated plates. The noise reduction of the sound barrier has a relatively important relationship with internal factors (such as noise frequency, barrier height) and external factors (such as the distance between the source point and the receiving point). A 2000 Hz high frequency sound is better than an 800-1000 Hz medium frequency sound, but a 25 Hz low frequency sound is better. The height of the sound barrier can be designed according to the distance between the sound source and the receiving point. If the height of the obstacle is doubled, the noise reduction can be increased by 6dB. However, for the low frequency sound of about 25Hz, because the wave length of the sound wave is relatively long, it is easy to diffract around the obstacle, so the effect is poor.
Advantages of stainless steel perforated plate
First of all, it has good permeability and can be used as filter screen, ventilation screen and safety net. In the case of no expansion at the same thickness, the expanded metal mesh is lighter and more economical than the steel plate, and its supporting force is also stronger than the steel plate. It can be used as sidewalk, platform, guardrail, machine protective cover and iron frame.
The precision of stainless steel punching plate die has a great impact on the equipment life and product quality. The die is fixed and unified, so the die must maintain its precision. When punching on high rigid press (such as double injection press and lower drive press), please use the pressure die holder or the die guided by the punch to increase the service life of the sieve plate and punching plate die and improve the product quality.

Maintenance method of vibrating screen motor
The vibrating screen motor is an exciting source that combines the power source and the vibration source. It is a vertical motor as the exciting force. An eccentric weight is installed at the upper and lower ends of the motor to transform the rotating motion of the motor into the exciting force generated by the horizontal, vertical and inclined three-dimensional motion

Performance Characteristics of Crusher Hammer
The hammer of the crusher should be accurately defined as the hammer of the hammer crusher. The hammer is one of the core parts of the hammer crusher, arranged on the hammer shaft of the crusher rotor. The hammer directly strikes the material when the crusher runs at high speed, and finally breaks into the appropriate particle size
