The submersible pump can not be half exposed on the water surface, it must be completely submerged in the water. This kind of water pump is different from the general water pump, its sealing insulation material is hot melting, if not put in water, the temperature will rise, and even lead to the melting of the sealing material, resulting in leakage of water and electricity, greatly reducing the safety performance.
1, the size of the cylinder: the choice of submersible pump is generally based on the size of the cylinder, to be exact, is the volume of water in the cylinder. The flow of the pump should be up to the standard, and the water in the tank must be circulated 7-10 times per hour, so as to ensure that the water body can be fully filtered, which is conducive to maintaining the water quality.
2. Size of the filter bin: The filter bin is the place where the filter material is placed in the filter, also known as the filter box. The larger it is, the more filter material it contains, and the larger the filter area is. Therefore, a higher flow rate is required to ensure the filtering effect. Otherwise, the water body cannot circulate many times in a certain period of time.
3. Breeding density: In addition to the above two factors, the breeding density should also be considered when choosing a submersible pump. If there are more fish, the amount of excretion will be very large, so it is necessary to clean the water body through a higher flow, otherwise the feces can not be sucked into the filter tank, resulting in the fish tank becoming very turbid.
