In recent years, it has been used in aquaculture breeding Roots blower It has been very common, but in the field of aquaculture breeding, due to the professionalism of aquaculture personnel, it is impossible to calculate the selection through the same formula and specific environment as in sewage treatment aeration Roots blower model model As a result, problems often occur. Hongguang Xiaobian combines many examples of aquaculture users Roots blower In aquaculture, how to choose a fan model that meets one's own needs and matters needing attention in use are summarized as follows:

1、 Selection method

This is a relatively difficult thing for aquaculture users to determine. Farming is generally divided into shed farming and open-air farming. About shed farming and open-air farming Roots blower The choice is different

The type selection of shed maintenance should be based on the pipe laying and pool area to calculate the use parameters of fan. In general, the laying of pipes in shed cultivation is divided into bottom aeration and upper aeration. The bottom of the tank is aerated with PVC pipe or aeration tray. Perforated PVC pipe, in Roots blower On the selection of water treatment, the selection method of environmental protection water treatment is generally followed. According to the number of aeration trays in each tank, the air volume should be calculated. The aeration on the tank is basically suspended nanotube or self sinking nanotube aeration. The air volume should be calculated according to the length of nanotubes used and the number of nanotubes distributed in each pool

The selection of open-air aquaculture is basically large-scale mud pond or pond with large land area. This kind of culture method generally uses nanotube aeration or nanotube connected with aeration plate (here the aeration plate is the nanotube aeration disc of mosquito repellent incense disc). Cultured Roots blower According to the floor area and the length of the nanotubes used or the number of aeration disks, the selection of the best choice should be based on the floor area and the length of the nanotubes used or the number of aeration disks Roots blower Air volume.

2. Matters needing attention in aquaculture

First of all, the power of the fan should keep up with the model of the fan. In the field of aquaculture, there is often a "small horse pulling a cart" situation, that is to use a small motor to drive the fan. Hongguang Roots blower The manufacturer's technical personnel tell you that this choice is because the owner thinks it saves electricity. It is precisely this type of configuration, which often leads to overpressure of the fan and over flow of the motor, which will not save power at all, but also cause problems of the fan and affect aeration. Now many owners of aquaculture adopt the power mode of frequency conversion motor, and use different current in different periods of breeding, which is a good way to save power. In order to reduce the cost of purchasing fans, most breeding users often choose fans with high speed, which is wrong. The higher the speed is, the shorter the service life of fans will be, and the higher the noise value of fans will be.

Second, the fan should be maintained in time. Because aquaculture is not like environmental protection sewage treatment aeration, more formal and field operation is more standardized, most of the breeding owners, in fact, do not have Roots blower In addition, the aquaculture site, Roots blower Because the aquaculture environment is relatively humid, it is generally affected by the sea, which will easily cause the rotor to rust and get stuck. Therefore, the daily maintenance and maintenance of the fan should be kept up with, and the lubricating oil should be replaced. If the fan is not used for a long time, the rotor should be added with diesel or lubricant and cleaned with empty car. Note: please do not Add viscous additives like cooking oil.

Hongguang Fan It is recommended for aquaculture users Double tank roots blower Structural, both sides of this type of fan are lubricated with gear oil. The user can directly see the oil level in the fan during maintenance, and add it in time to avoid the fan running under the condition of oil shortage or insufficient oil quantity, which will cause fan damage and bring unnecessary fan fault to breeding users. In order to increase the cost of aquaculture, the most important is to affect the use of aquaculture shrimp, fish, etc. bring huge losses, in this small series of recommendations for each use Roots blower Once the fan fails, the standby machine can be used to replace the fault machine for oxygen filling, so as to minimize the loss or even no loss.
