Roots blower for fish pond culture

The roots blower is a kind of equipment that can transfer the oxygen in the air to the aquaculture water quickly by driving the working parts by the power source such as electric motor or diesel engine. It can make comprehensive use of physical, chemical and biological functions. It can not only solve the problem of fish floating head caused by hypoxia in pond culture, but also eliminate harmful gases and promote the development of aquaculture The results show that the convective exchange of water body can improve the water quality, reduce the feed coefficient, improve the fish pond activity and primary productivity, so as to increase the stocking density, increase the feeding intensity of the breeding objects, promote the growth, greatly increase the yield per mu, and fully achieve the purpose of increasing the aquaculture income

According to the professional staff in the field of Roots blower, roots blower acts as the main structure of biological wastewater treatment in the aeration work of water treatment. In order to maintain the life activity of microorganisms, it is necessary to ensure that there is a certain amount of dissolved oxygen in the water. Aeration is to continuously inject air into water or dissolve oxygen in air into water. Aeration tank is generally made of reinforced concrete, mainly through roots blower and mechanical aeration.

Roots blower in this application should pay attention to the following matters.

The main way of blower aeration is also called compressed air aeration. Roots blower, vortex fan, water ring fan, centrifugal fan, rotary fan and so on can be used as the main aeration equipment. When roots blower is tested before ventilation, ventilation detection shall be conducted before water supply. Before ventilation, fan shall be started and 50% air volume shall be sent to aeration pipeline of biochemical tank for detection. The pipeline shall be free of air leakage. At this time, special attention should be paid to the operation of the fan. During the leakage test, a proper amount of lubricating oil should be continuously added to the tuyere to ensure the normal operation of the equipment and avoid no-load operation. The lubricating oil can not be automatically recycled when there is no pressure, so as to avoid the equipment running without oil.

The weather is hot in summer, and the outdoor temperature in some areas reaches 40 degrees centigrade. However, fish pond farms are breeding outdoors, so roots blowers are used outdoors. Therefore, the hot high temperature still has a certain impact on Roots blower (the higher the temperature will affect the service life of Roots blower), so it is necessary to maintain roots blower in summer. The specific maintenance methods are shared with you:

How to maintain roots blower for fish pond culture in summer?

The type of aerator must be clearly understood in order to maintain and repair roots blower correctly in summer.

Impeller type: it can increase oxygen, stir water and aerate. It is suitable for increasing oxygen in large area pond with water depth more than 1 m. It does not damage the fish body and is suitable for the use of oxygen enrichment in the fish fry pond.

Spray type: it has a good function of increasing oxygen, rapidly increasing the dissolved oxygen content of surface water in a short period of time. At the same time, it has the effect of artistic appreciation. It is suitable for the use of fish ponds in gardens or tourist areas.

Aerated: the deeper the water, the better the effect. It is suitable for fish culture in deep water. But no matter what kind of maintenance is indispensable, such as avoiding direct sunlight, reducing the temperature of the blower and so on.

In summer, the main maintenance of Roots blower for fish pond culture is cooling, because the higher the temperature of Roots blower is, the service life of Roots blower will be affected after exceeding a certain limit.
