The growth of chicken flocks requires a relatively quiet environment. Too much noise may cause stress reactions in the flocks, affecting the growth performance of the flocks and directly affecting the economic benefits of the farmers. The chicken cage equipment fan is the necessary ventilation equipment for intensive chicken farms. There will be some noise during the operation of the fan. How to reduce the noise of the fan during operation? The authors refer to the recommendations of the poultry equipment suppliers and summarize the following ways to reduce the noise of the wind turbine.
1. The farmer is suitable to operate the fan equipment. The noise in the casing and the motor can be solved by installing an acoustic enclosure.
2. Rotating parts such as fan impeller, fan shaft, pulley and coupling should be calibrated during installation. If no correction is made, noise may occur during operation. At the same time, the farmers should pay attention to the motor cooling, the gap between the fan blades and the air guiding ring, etc., which can effectively reduce the rotating noise of the motor cooling fan blades.
3. The fan has been used for a long time, and it is inevitable that there will be looseness between the screws, which will increase the noise of running. Therefore, the farmers should regularly check whether the bolts of the fan parts are loose, whether the bearings of the fan are abnormally worn or poorly lubricated, and the transmission of the fan equipment does not appear to be tensioned. If the situation is found to be abnormal, it should be excluded immediately.
4. Farmers should pay attention to the installation of fan equipment for chicken equipment. Soft materials such as rubber, cork board or felt board should be placed between the fan and the reinforced concrete foundation. The vibration transmitted to the reinforced concrete foundation by the centrifugal fan is minimized or eliminated.
5. The method of reducing noise by the farmers, and a rubber hose can be installed at the air inlet and the air outlet of the fan. In this way, the vibration transmitted to the air duct by the centrifugal fan of the chicken equipment can be greatly reduced or eliminated at the rubber hose, which can also reduce a large part of the noise.
6. Farmers can reduce the noise of the fan. They can also choose to install a muffler outside the fan exhaust port, and then place a muffler insert in the fan. This can reduce the noise when passing through a specially constructed muffler. Currently, the muffler is to reduce the air. Effective measures for the radiation of the power equipment into the exhaust port or the noise transmission along the pipe are also the methods that many farmers choose to build noise.
The above are some methods and points that are introduced to farmers to reduce fan noise during the use of auxiliary fan blades for poultry farming equipment.
