一. The driving principle of variable Inverter submersible pump
The working principle of the frequency conversion submersible pump: the frequency conversion submersible pump changes the speed of the motor by changing the frequency of the power supply, thereby changing the water output of the pump, and the speed of the frequency conversion submersible pump determines the size of its water output.
The closed-loop control principle of the variable frequency submersible pump is to compare the [actually set target pressure value] with the [current actual detected pressure value], and change the difference to approach and zero through a series of function algorithms.
In the process of frequency conversion speed regulation of variable frequency submersible pump equipment, when the water pressure drops fast, the frequency converter speed regulation process is accelerated, and vice versa. Under the condition that the flow and lift are all satisfied, the output pressure of the variable frequency submersible pump can be constant, and a pressure error value of ±0.01MPa is allowed.
二. Advantages of frequency conversion pump for fish tank
1. The speed regulation efficiency of the fish tank water pump is high, which belongs to the high-efficiency speed regulation method. This is because after the frequency changes, the fish tank water pump motor is still running around the synchronous speed and basically maintains the rated slip. It
is only in the frequency conversion device system that there will be a loss of variable flow, and due to the influence of high-order harmonics, the loss of the fish tank water pump will increase, thereby reducing the efficiency.
2. The speed regulation range is wide, generally up to 20:1, and has high speed regulation efficiency in the entire speed regulation range. Therefore, frequency conversion speed regulation is suitable for occasions where the speed regulation range is wide and often runs under low load conditions.
3. The mechanical characteristics are relatively hard. When there is no automatic control, the speed change rate is below 5%; when automatic control is used, it can perform high-precision operation and control the speed fluctuation rate to about 0.5%|~1%.
4. In case of failure of the frequency conversion device, the fish tank water pump can be automatically protected to avoid damage to the pump body.
三. Working principle and operation precautions of frequency conversion pump for fish tank
The "frequency conversion" in the frequency conversion pump of the fish tank refers to a frequency conversion process for the main motor of the water pump. The frequency conversion of the
frequency conversion water pump refers to the motor, and the frequency conversion water pump should be a water pump driven by a frequency conversion motor. By changing the frequency of the motor to change the speed of the motor, so as to achieve the adjustment of technical parameters
such as the flow head of the pump, and play a control role. The fish tank frequency conversion pump provides water circulation for the fish tank, and applies the DC frequency conversion speed regulation technology and the microcomputer control technology to the fish tank submersible pump to automatically control the fish tank ecosystem.
The working principle of the frequency conversion water circulation of the fish tank variable frequency water pump 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 The 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
Precautions for the operation of frequency conversion water pumps in fish tanks: frequency conversion water pumps are generally wide voltage voltages, which can be used when the voltage is greater than or less than 15% of the normal voltage. Please clean the rotor and impeller regularly.
The user must check whether the rated voltage of the pump is consistent with the actual voltage before use. When installing or removing and cleaning the water pump, you must first unplug the power plug and cut off the power supply to ensure safety.
It is necessary to clean the filter basket and filter cotton frequently to ensure normal water intake and good filtering effect. To protect the pump body, if it breaks, please stop using it immediately. The water pump should be immersed in water no less than 0.4 meters. The wire used by the water
pump is also very important, because it is immersed in water for half of the time, even in salt water, and the long-term immersion will 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.
四. Minor fault repair method
1. The rotor bearing is worn, resulting in the non-rotation caused by the friction between the rotor impeller and the pump head.
2. The driver board, wire package and MOS tube are burned out.
3. The PBC board and resistor are burned out.
4. Short circuit, the voltage stabilizer level is damaged.
5. There are debris in the rotor shaft.
6. The shaft core bracket of the pump head is broken.
7. Poor encapsulation will cause the PBC board to be burned out by water.
五. How to maintain the frequency conversion fish tank pump
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 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 soaked in water half the time, even 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.
六.Does the fish tank pump need frequency conversion?
The fish tank water pump must be frequency-converted, which can be used to adjust the speed of the water pump. 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. In addition, pay attention when using it, you must first check whether the rated voltage of the pump is consistent with the actual voltage.
