Are pumps harmful to fish? What is the function of a fish pump

Submersible pump head calculation method: The effective energy obtained by the unit weight of liquid after flowing through the pump. It is an important working performance parameter of the pump, also known as the pressure head.

It can be expressed as the increase of the pressure energy head, kinetic energy head and potential energy head of the fluid, i.e., h=(p2-p1) g+(c2 2-c1 2) 2g+z2-z1 where h—head, m; P1, P2—the pressure of the liquid at the inlet and outlet of the pump, Pa; C1, C2—the flow rate of the fluid at the inlet and outlet of the pump, m s; z1, z2 - inlet and outlet height, m; Liquid density, kg m3; g—acceleration due to gravity, m s2.

The function of the water pump is to allow the water to fully contact oxygen. Generally, it doesn't need to be open 24 hours a day, just one meeting a day.

If the current is too strong, there is a risk of harming the fish.

The pump will definitely work for 24 hours. Oxygenation. The water in the fish tank needs to be changed after a while. Some hotels feed fish at low temperatures to inhibit bacteria. Potassium permanganate disinfection and sterilization.

It's not a disease, it can't be opened 24 hours a day, just hold it for a while!

Your pump flow is a bit big and <. Somewhat small, not a disease. It is recommended to buy a small power pump that is always open.

It will affect the fish, and it needs to be placed in a stable place, the surrounding environment should be clean, dry and ventilated, and the direction of rotation of the impeller must be consistent with the direction of the arrow marked on the fan housing.

When working, the working pressure shall not be greater than the rated maximum air pressure of the model, so as not to cause excessive heat to the air pump and the motor overcurrent to cause damage to the air pump, except for the two bearings of the motor rotor, there is no direct contact friction in other parts.

The filter screen and silencer device at both ends of the inlet and outlet air should be cleaned in a timely manner according to the situation to avoid blockage and affect the use, and the external connection of the air inlet and outlet must be connected by hose (such as rubber pipe and plastic spring pipe).

1. The function of the fish pump is to make the water flow, so as to increase the contact surface between the water and the air, increase the dissolved oxygen and increase the oxygen content in the water.

2. The key to raising good fish is filtration, and filtration is mainly to filter fish feces, and the dirty things in the filter tank such as fish feces ensure basic water quality, and the toxins in the water are produced by fish feces.

3. It plays the role of water circulation in the fish tank; It's not that the longer the better, it's better to get close to the low cylinder.

4. The general aquarium filtration system is mainly upper filtration, drip flowing, bottom filtration, filter barrel, side filtration, and back filtration, and these filtration systems are different in form, but they are essentially the same, and they are all filtration systems for cultivating nitrifying bacteria outside the tank.

Summary. Dear, hello, thank you for your consultation, about your questions, for you to answer the following: the size of the fish tank pump inlet has an impact on the pumping force, this is because the size of the water inlet will affect the water inlet and water inlet speed of the pump, thus affecting the pumping effect of the pump.

If the water inlet is too small, the water inlet and water inlet speed of the pump will be limited, which will affect the pumping effect of the pump. Conversely, if the inlet is too large, the amount of water and the speed of the pump will increase, but it will also increase the noise and energy consumption of the pump. Therefore, choosing the right size of the water inlet is very important for the pumping effect and service life of the pump.

If the water inlet is too small, the water inlet and water inlet speed of the pump will be limited, which will affect the pumping effect of the pump.

Conversely, if the inlet is too large, the amount of water entering the pump and the rate of ingress of silver water will increase, but it will also increase the noise and energy consumption of the pump. Therefore, choosing the right size of the water inlet is very important for the pumping effect and service life of the pump. The size of the inlet of the fish tank pump has an impact on the pumping force Oh dear The above is mine, I hope it can help you, thank you for your consultation, I wish you a happy life and all the best.

Is it true that the water inlet is small and the pumping force is large at the same power?

Yes, but it should not be too small, too small will affect the water intake and thus the pumping.

Summary. Hello, I'm Little Crispy. Yes, the size of the inlet of the pump will affect the pumping force.

A smaller inlet will result in a lower efficiency of the pump and a weaker pumping force, while a larger inlet will increase the efficiency of the pump and the pumping force will also increase. Therefore, when choosing a fish tank pump, you should pay attention to the size of the water inlet. In addition to the size of the water inlet, the pumping force of the pump is also affected by the pump structure and the parameters of the pump motor.

The structure of the pump is required to be selected reasonably, and the parameters of the pump motor are required to be selected appropriately. If the pump structure and pump motor parameters are reasonable and appropriate, the pumping force of the pump will be better. In addition, the size of the inlet of the pump needs to be selected correctly to achieve the best results.

Chuangning water pump external is better to choose 25 tubes or 20 tubes! Water inlet.

Hello, I'm Little Crispy. The choice of an external inlet depends on the diameter of your pipe. If the diameter of the pipe is greater than 25mm, it is recommended that you use 25 pipes; If the diameter of the pipe is less than 20mm of the bush limb, it is recommended that you use 20 tubes.

It is recommended that you choose according to the actual situation to ensure the best performance of the pump. In addition, you also need to consider the width of the installation environment, if the width of the environment is smaller, you can consider using 20 tubes; If the width of the environment is larger, 25 tubes can be considered. It is recommended that you choose according to the actual situation to get the best performance.

In a word, according to your actual situation, choose 25 pipes or 20 pipes for installation, you can get good pump performance.

Summary. Hello dear, for you to find out, the size of the water inlet of the fish tank pump has an impact on the pumping force.

Hello dear, for you to find out, the size of the water inlet of the fish tank pump has an impact on the pumping force.

The size of the inlet of the fish tank pump will affect the pumping force of the pump. If the inlet is too small, the water flow will not be able to pass through, thus hindering the pumping force of the pump; On the contrary, if the inlet of Tongchang Bridge is too large, a large amount of water will pass through, thus increasing the pumping force of the pump. Therefore, the pumping force of the pump can be adjusted quickly by adjusting the size of its inlet.

The larger the inlet, the greater the pumping force, right?

No, there is no direct relationship between the size of the inlet and the axial force. The axial force lead is determined by the water flow rate, the water flow bucket speed and the depth of the bottom of the cylinder. The water inlet is just a regulator of flow and speed, and it can control the speed of water flow.

The fish tank pump is too large, which may cause filtration overflow, and will also cause the fish tank to be surfing all the time, which is too electricity-intensive.

For example, if the capacity of your fish tank is 200 liters of water, then the pump with 10 times the flow rate should be 2000 liters per hour.

The water volume of the fish tank is calculated by multiplying the length of the fish tank by the width of the height, the unit is calculated in centimeters, and the resulting value is divided by a thousand, and the final result is the number of liters of water in the fish tank. For example, the water in the bottom filter fish tank should also be counted.

In order for the fish to survive in conditions with more adequate oxygen, it is used to pump oxygen.

Water Pump: A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy or other external energy of the prime mover to the liquid, so that the liquid energy increases, and is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal, etc., and can also transport liquids, gas mixtures and liquids containing suspended solids.

The technical parameters of pump performance include flow, suction lift, head, shaft power, water power, efficiency, etc.; According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. Positive displacement pumps use changes in the volume of their studios to transfer energy; Vane pumps use the interaction between rotary vanes and water to transfer energy, and there are types of centrifugal pumps, axial flow pumps and mixed-flow pumps.

It is not enough to have aquatic plants alone, but it is necessary to circulate with a water pump to increase oxygen. Install an aeration pump.
