 No water power supply: When the water pump is in an anhydrous state, turn on the power supply, and then the pump will speed up to the maximum speed and immediately detect the low-speed

 rotation state, that is, the water-free protection state set by our company. In this case, after running in a water environment, if the water shortage is detected, the water pump will also be transferred to the no-water protection state from the load condition, that is, the low-speed rotation state!

Power on with water: When the water pump is in the state of water, turn on the power supply, and the pump will be in the state of maximum speed. At this time, you need to use the acceleration and deceleration function keys to adjust to the required optimal flow and head.

 Power failure memory function setting: After adjusting to the required optimal flow and head according to step 2, such as 5th gear, press the button, and when the indicator lights are all off, press the button again to start the water pump, and the water pump will enter the memory state. At this time, if the use process In case of power failure, when the electric water pump starts to run, it will directly run to the adjusted gear (gear 5)

Feeding function setting: When feeding, press the button, the pump will immediately enter the low-speed operation state, and the pump will automatically return to the set normal working state after 15 minutes.

It is to adjust the speed of the running water pump according to the change of the water consumption of the fish tank, so that the outlet pressure of the fish tank submersible pump remains constant. When the circulating water consumption of the fish tank is small, the frequency conversion speed of the fish tank water pump can be adjusted to an appropriate frequency according to the

change of the water consumption. When the water consumption is reduced, the speed of the water pump is slowed down to maintain a constant pressure. In the whole operation process, the constant pressure of the system is always kept unchanged, so that the fish tank circulating pump always works in the high-efficiency area, which not only ensures the user's constant pressure water supply, but also saves electricity.

"The water pump needs to be disassembled and cleaned regularly. There is a lot of filth in the aquarium, such as fish feces, rotten aquatic plants, and residual feed, which may be sucked into the water pump. Due to the direction of rotation of the water pump and the nature of the impurities, a A small part will remain in the pump, and impurities are most likely to be trapped between the turbine chamber and the rotor stator. These dirt will reduce the water flow of the pump, increase the

working temperature, and increase the noise. Therefore, it is recommended to clean the pump once a month. Open the protective cover of the water pump, remove the turbine, rotor and shaft, and thoroughly clean the inside of the water pump. Use a waste toothbrush to clean the surface or dead corners. When cleaning, pay attention to the small internal parts, it will be troublesome if they are lost.”

l Frequency conversion speed regulation and water pump energy saving

The energy saving of the pump is inseparable from the reasonable adjustment of the working point. The adjustment methods are nothing more than the following two: adjustment of the pipeline

characteristic curve, such as valve closing adjustment; adjustment of the pump characteristic curve, such as pump speed regulation, impeller cutting, etc. In terms of energy saving effect, the method of changing the performance curve of the pump is much more significant than changing the

characteristic curve of the pipeline [1]. Therefore, changing the performance curve of the pump has become the main way to save energy in the pump. The frequency conversion speed regulation has obvious advantages in changing the performance curve of the pump and automatic control, so it is widely used. But at the same time, it should be noted that there are many factors that affect the energy-saving effect of frequency conversion speed regulation. If blindly selected, it is likely to backfire.

2 Factors that affect the range of variable frequency speed regulation

Pump speed regulation is generally a deceleration problem. When frequency conversion speed regulation is adopted, the operating parameters of the pump and motor originally designed according to the power frequency state have undergone great changes. In addition, factors such as the pipeline characteristic curve and the fixed speed pump running in parallel with the speed

regulating pump will all affect the The range of speed regulation has a certain effect. Over-range speed regulation is difficult to achieve the purpose of energy saving. Therefore, it is impossible to control the speed without limit. It is generally believed that the frequency conversion speed regulation should not be lower than 50% of the rated speed, preferably 75% to 100%, and should be determined by calculation based on the actual situation.

1. The water pump needs to be disassembled and cleaned regularly.

There is a lot of filth in the aquarium, such as fish feces, rotten aquatic plants, and residual feed, which may be sucked into the pump. Due to the direction of internal rotation of the pump and the nature of impurities, a small part will remain in the pump, and impurities are most likely to be

trapped between the turbine chamber and the rotor stator. These dirty things will reduce the water flow of the pump, increase the working temperature, and increase the noise.

Therefore, it is recommended to clean the water pump once a month, open the protective cover of the water pump, remove the turbine, rotor and shaft, thoroughly clean the inside of the water pump, and use a waste toothbrush to clean the surface or dead corners. When cleaning, be sure to pay attention to the small internal parts, it will be troublesome if lost

2. Do not install the water pump too close to the sand.

Some people like to install the water pump close to the bottom of the fish tank, thinking that the dirt will be completely pumped, but it is meaningless. As long as the pump is circulating, the dirt will be pumped into the filter along with the water flow. Installing the pump too low may suck the grit from the bottom of the aquarium into the pump, which can seriously affect the life of the pump as it rotates.

3. Pay attention to the wires of the pump.

The wire used by the water pump is also very important, because it is submerged in water half the time, even in salt water, and prolonged soaking can make the wire stiff and even broken. In about 5-7 years, the wires above the water pump can be eliminated, and new wires should be replaced.

Answered by the above text, is it necessary to frequency conversion for the fish tank water pump? How to maintain the frequency conversion fish tank pump? They should already know it. In fact, the fish tank water pump can also adopt frequency conversion, which can save electricity to a certain extent. In addition, it is very important to maintain the fish tank. Only with correct maintenance, the fish tank can be used for a longer life.
