1. What size of water pump should be used for a fish tank with a length of 40, width of 23, and height of 28?
When selecting a water pump for a fish tank, it is necessary to consider the volume, flow rate requirements, and actual scene. For a fish tank with a size of 40 × 23 × 28cm, it is recommended to choose a water pump with a flow rate of 2-44L/h, which needs to be adjusted according to the filtration type, feeding density, etc.
1. Calculate the volume of the fish tank and the range of the basic flow rate.
Volume calculation: Fish tank volume=length × width × height (unit: cm) ÷ 1000=40 × 23 × 28 ÷ 1000 ≈ 25.76L (note: the actual water level should be lower than the tank mouth, with a volume of about 22-24L)2. Flow principle: The water pump flow rate usually needs to reach 1-2 times the fish tank volume per hour (i.e. 22-48L/h). If it is bottom filtration/drip filtration, it can be appropriately increased to 2-3 times (4-72L/h), but it is necessary to avoid excessive water flow that affects fish.
2. Selection of Water Pumps for Different Scenarios Reference 1 Ordinary upper filter/external filter: It is recommended to choose a water pump with a flow rate of 25-35L/h (such as a small submersible pump), which can balance filtration efficiency and water flow mildness. 2. Bottom filter/drip filter: A water pump with a flow rate of 4-60L/h can be selected, which needs to be matched with a reasonable pipeline to reduce water flow impact. 3. Water grass tank/small fish feeding: Priority should be given to a flow rate of 20-30L/h to avoid water flow disturbance to water grass or startling small fish such as lanternfish and catfish.
III. Additional Precautions 1 Head matching: The he
2. Mute requirements: Choose a water pump with anti pants, coarse vibration foot pads, and ceramic shafts to avoid noise affecting daily life
3. Brand reference Hu Zhen: Consider aquarium specific water pumps such as Sensen, Jiabao, and Chuangning, and confirm that the flow labeling is consistent with the actual water output.
2. Kneeling down to calculate the size of the fish tank, how much water is used, and how much flow is filtered.
The calculation method for how much water is used in the fish tank and how much flow is filtered is generally to first calculate the water capacity of the fish tank.. The formula is=length shed * width * height (unit: centimeter)/1000=liter or length * width * height (unit: decimeter)=liter 2- generally suitable for a water pump with a capacity of 5 times the flow rate. For example, a fish tank can hold 400 liters of water and is compatible with a water pump with a flow rate of 2000L/H, which is 5 times that of Xianzhi. Approximately a 35W water pump. There are several models of single-stage double suction centrifugal pumps, including S-type, Sh type, SA type, and SLA type. The difference between S-type and Sh type is that, from the driving end, S-type pumps rotate clockwise, while Sh type pumps rotate counterclockwise. SLA type is a vertical single-stage double suction centrifugal pump. The performance range of S-type pump is flow rate of 160-18000 cubic meters per hour, head of 12-125 meters, i
