After the aerator has been used for a long time, the air inlet is broken due to rust. This type of aerator is mainly reflected in the aerator produced in Jiangsu area, which uses a small air intake filter! Roots aerators produced in Shandong generally rarely have this situation. The above is matched with a cast iron intake filter, which can generally be used for about 5-10 years! However, the user needs to regularly clean or better the filter surface of the air inlet. Avoid dust, dust and particles in the air from entering the inside of the three-blade rotor!
If the user encounters the situation just mentioned, the user should contact the original factory of the device as soon as possible and replace the accessories in time! The position of the intake filter is still very important. When there is no timely replacement of parts, the user can wrap the air inlet with gauze to prevent debris from entering the interior of the aerator through the air inlet.
Aeration facilities: Water lobsters are resistant to hypoxia. Generally, a 3-4 mu of aquaculture ponds without aquatic plants is equipped with a 1.2kw aerator, which is installed in the center of the pool to keep the water flowing to the greatest extent and fully aerate. The microporous aeration tube is generally sunny. It is not necessary to turn on the aeration equipment during the day. It only needs to be turned on at night to ensure the dissolved oxygen needs of the breeding process.
One lkw aerator per acre of water surface is used in the early stage, and the number is increased to two in the middle and late stage. Small shrimp ponds can use a gas lift pump to move water and increase oxygen, and use a Roots blower to supply air, and the air supply per minute should reach More than 0.5-1% of the total water body for aquaculture, those with sufficient water sources can also use the water spray to promote the flow of the pool water.
