1. How to calculate the flow rate and Yang Cheng of the fish tank water pump?
The flow rate of the fish tank water pump is calculated based on the total amount of water circulating 4-5 times per hour, and the head is increased by 20% -30% according to the actual lifting height, or the pipeline loss is calculated The flow rate of the fish tank water pump is determined by the total amount of water in the fish tank and the required number of cycles: flow rate (L/h)=fish tank water volume (L) x number of cycles (times/hour). -Conventional requirement: It is recommended to cycle 4-5 times per hour for a typical fish tank, for example, a water pump with a flow rate of 1200-1500L/h should be selected for a 300 liter water tank. Wide hunger - special adjustment: breeding high oxygen consuming fish or water grass tanks can be increased to 5-8 cycles; Bare tank or low-density fish farming can be reduced to 3-4 cycles
2. Head calculation: The head needs to meet the vertical lifting height from the water pump to the outlet and overcome pipeline resistance: - Basic calculation: Head ≥ the vertical height from the water surface to the outlet × 1.2-1.3 (with a 20% -30% margin reserved). For example, when the vertical height is 0.3 meters, a water pump with a lift of 0.36 meters or more should be selected. -Accurate calculation (including pipeline losses): total head=vertical height+pipeline loss head. The pipeline loss is accumulated at 0.05-0.1 meters per meter of straight pipe and 0.02-0.05 meters per meter of elbow. For example, a vertical height of 0.3 meters, a pipeline length of 2 meters (loss of 0.16 meters), 2 bends (loss of 0.06 meters), and a total head of 0.52 meters are required.
3. Operation example:
What size of water pump is needed for a 2.60 fish tank? What is the flow rate of the water pump used for a 60 meter fish tank?
Use a 10w-12w (fixed frequency) or 6w-13w (variable frequency) water pump for the 60 fish tank, with a flow range of 413L/H-791L/H.
1. The water volume range of a 60 cm fish tank refers to a length of 60 cm, but the width and height are not clearly defined.
. Therefore, it can only be listed based on common sizes on the market. For example, with a length of 60 centimeters, a width of 30 centimeters, a height of 36 centimeters, and a water level of 33 centimeters, the total water volume of the fish tank is approximately 59 liters. The fish tank measures 60 centimeters in length, 35 centimeters in width, 40 centimeters in height, and 37 centimeters in water level. The total water volume of the tank is approximately 77 liters. The fish tank measures 60 centimeters in length, 40 centimeters in width, and 40 centimeters in height, with a water level of 37 centimeters. The total water volume of the tank is approximately 88 liters. The fish tank measures 60 centimeters in length, 40 centimeters in width, 45 centimeters in height, and has a water level of 42 centimeters. The total water volume of the tank is app
