The harm of noise pollution The pregnant woman is in a noise environment of more than 50 decibels for a long time, will cause the endocrine gland function disorder, and appears the nervous tension and the endocrine system disorder. Severe increase in blood pressure, fetal hypoxia and ischemia, leading to fetal malformation and even miscarriage. High-decibel noise can damage the fetus's auditory organs, causing some areas to be affected. Affects the development of the brain and leads to mental retardation in children.
The vicious stimulation of noise seriously affects our quality of sleep, and can cause dizziness, headache, insomnia, dreaminess, memory loss, inattention and other symptoms of neurasthenia and nausea, vomiting, stomach pain, bloating, appetite, etc. symptom. In view of the noise pollution and hazards mentioned above, for the sake of the people's physical and mental health, the Botou Tengxue tile-waving machine factory decided to put the color steel tile presser's pitch reduction work on the agenda and take the following measures:
(1) Adopting a high stiffness motor that reduces the magnetic field density and adopts a method of suppressing the vibration of the iron core or adopting a cast iron housing;
(2) Select low-noise cooling fans and reactors;
(3) automatic pressure tile machine inserts a reactor between the inverter and the motor to reduce the higher harmonics caused by the PWM control mode;
(4) Insert a filter between the inverter and the motor to convert the waveform (voltage, current) into a sine wave.
(5) Select low-noise inverters such as LA IGBTs as commutation devices or inverters using PAM control mode
