The heat required is mainly provided by boiler coal
However, almost all of these coal-fired boilers have problems of noise exceeding the standard and energy waste. Shanghai Dongfeng Pump and Valve Factory is committed to noise control of water pumps and equipment units in the machine room. It has rich experience in the industry. Please call us for advice
ZD type damping ball valve damper pneumatic butterfly valve of water pump -- noise is generated by the operation of the machine room or equipment in the pump room at the pump room noise control site. Installing pneumatic butterfly valve of water pump and damper ball valve damper can effectively solve the noise control: 1. The water pump, water chiller, fan coil, air conditioning unit and other equipment are connected with the water pipe by flexible pipes, so that the vibration is not transmitted to the pipeline
There are two types of hoses: soft receiver and stainless steel bellows
The effect of soft receiver vibration isolation and noise reduction is very good. The defect is that it cannot withstand high temperature and high pressure, and its corrosion resistance is also poor
Multi purpose reception in the water system of air conditioning and heating
Stainless steel bellows can withstand high temperature, high pressure and corrosion, but the price is expensive. It is commonly used for vibration isolation of refrigerant pipeline
2. Control the wind speed of air duct and air outlet according to the noise specification to meet the requirements of room noise. Although the appearance is relatively small, the application life is not short
