How to select the type of roots aerator and how to select the "roots blower"
It is easy to lack oxygen in greenhouse, especially from 4:00 to 7:00 in the morning. Therefore, the time of opening the aerator should be at night. In addition, in the middle and late stage of breeding, as well as rainy days, cloudy days should be started in time. At noon, the sun is abundant, photosynthesis is strong, and it is not easy to lack oxygen. The main purpose of starting the machine at noon is to stir the water body, make the upper and lower water bodies produce convection, send the surface and upper layer of saturated oxygen to the bottom layer, at the same time, send the low oxygen or hypoxia water body of the bottom layer or lower layer to the upper layer, and bring its inorganic salts to the upper layer, so as to provide nutrition for the upper layer phytoplankton and maintain the ecological balance of the water body.
Roots aerator Roots blower is used to For example, there are many types of aerators that have been widely used in aquaculture industry. In the small online editor to see a lot of friends in search of such words: 30 mu with how much Roots aerator How much to use for 10 mu and 40 mu, and the selection of aerator model will be affected by these parameters
1、 Number of aeration trays
If the number of aeration trays is large, the ones that need models are larger. If the number of aeration trays is less, the models will be smaller.
2、 Breeding density
The higher the breeding density, the larger the model of fan is required.
3、 Breeding depth
The deeper the breeding depth is, the water depth will directly affect our selection. The pressure of the fan will affect the selection of motor power. Different motor power will also affect the overall quotation. The higher the motor power requirements are, the larger the motor needs to be configured. If you want to select the type of roots aerator, you need to have air volume and pressure parameters. If you don't have air volume and pressure parameters, you can prepare parameters of breeding area and water depth. According to the previous model, we can recommend a model for you according to the water depth and area. If you need a customer case of roots aerator, you can contact our online customer service. Fan selection or if you need to purchase
4、 Selection of aerator
Since this friend had not used roots aerator before, he was also the first time to purchase. He asked how much the 7.5kW roots blower cost. There are two parameters for the selection of Roots blower, one is air volume parameter, and the other is pressure parameter. The pressure parameter can be estimated by the average water depth of the pond. The air volume parameter is rarely available in individual farmers, and the air volume parameter can be obtained through breeding Area and stocking density were calculated. The basic parameters of roots aerator selection parameters are air volume and pressure parameters. If it is a large-scale breeding base, there will be professional technical personnel to design the parameters. The design parameters are mainly air volume and pressure, which are designed according to their own breeding area and breeding density.
5、 Most models are recommended
Roots aerator In addition to parameter calculation for large-scale breeding bases, most of them are recommended by experience, Roots aerator The model, we met in the customer, is also based on our own many years of experience to recommend to you.
7、 Breeding area
choice Roots aerator According to my experience for many years, we can draw a general range of models, but it is not enough.
6、 The problem of pulling fish with nets
When our fish are out of the pond, they are usually pulled through the net. For the industrial breeding base, we can use the net directly. Because the industrialized breeding base has pre installed the aeration plate at the bottom of the pond when building the pond, so the net drawing will not affect the aeration plate. If we are a personal pond aquaculture, we will install roots aerator in the later stage. When the pond is discharged in the later stage, we suggest that the aeration plate and aeration hose should be removed first, and then the pond should be cleaned. If we haven't laid the net yet, we can pre install the aeration tray.
Summary: if selected Roots blower Bottom microporous aerator. It can be estimated by the formula of aquaculture aeration type selection, and the inlet volume flow QS is more than X1.5% of the pool water volume (m3 / h). In this way, the required flow can be calculated according to the situation of the fish pond, and the water depth of the fish pond can be determined Roots blower 1 meter water depth is equal to 9.8 kPa, 2 meters water depth is equal to 19.6 kPa, and so on, the parameters can be determined by consulting the manufacturer Roots blower Flow parameters and number of units.
