In industrial production, the noise generated by the operation of chillers is a common problem. Noise not only affects the working environment, but may also indicate internal problems with the equipment. Here are some reasons and solutions for excessive noise in chillers:
1. Installation environment
The installation environment of a chiller has a significant impact on its noise level. If the chiller is installed in a narrow space, the noise will be amplified. It is recommended to install the chiller in a spacious area, away from other debris, to reduce noise. If there are strict requirements for environmental sound, soundproof panels can be installed and good ventilation and heat dissipation can be ensured.
2. The design of the chiller itself
The structure of air-cooled and water-cooled chillers is different, and air-cooled chillers are more prone to generating noise. The air-cooled chiller uses a centrifugal fan to dissipate heat from the cooler, while the water-cooled chiller uses a cooling tower system. Centrifugal fans have high noise levels and are integrated with industrial chiller servers, which can easily make people feel uncomfortable. You can try removing dust from the fan blades or adding lubricating oil to the rolling bearings to reduce noise.
3. Centrifugal water pump
Both air-cooled and water-cooled chillers have centrifugal water pumps. If the running noise of the water pump is too loud, it may need to be inspected and cleaned. The compressor of the chiller is also one of the sources of noise, and choosing a low-noise compressor can effectively reduce the overall noise level.
4. Compressor status
The continuous operation time of the refrigeration compressor, the use of lubricating grease, and the service life can all affect the noise level of the chiller. To reduce compressor consumption and noise formation, the following inspections and maintenance can be carried out:
Check if the position of the lubricating grease in the body and fuel pump is normal.
Check the sensitivity and fuel volume of the fuel pump.
Check for oil, water, and air leakage in the refrigeration compressor and promptly address them.
Check if the gate valve is opened correctly.
Check if the equipment vibration is normal, and if necessary, shut down for inspection and handling.
Check if the dashboard display is normal.
Check the coarse (fine) filtration device of the lubricating oil and regularly replace or clean the coarse filter.
