Attentions When Using The Commercial Water Fountain Pumps

The commercial water fountain pumps are actually a submersible pump for wells. It is specially developed for agricultural drainage, sprinkler irrigation, drainage systems of industrial and civil buildings. It is suitable for ponds, fish ponds, water towers, deep wells and high-rise buildings.

Water feature fountains have high corrosion resistance to the motor. Usually, all stainless steel or high-tech materials are used. The impellers are also special materials to prevent the impellers from loosening. There is a special potentiostat grounding device for leakage protection. The pump body also has a stainless steel filter. Shield and three-phase four-wire cable. Because the music fountain needs to change its shape with the music rhythm, professional water pump companies continue to carry out technical research and development based on the original ordinary commercial water fountain pumps, so that the pump can be started frequently and fully meet the use of the fountain. At the same time, the larger the fountain area, the higher the power requirements of the commercial water fountain pumps. In order to meet all kinds of fountains, the specifications of vertical-horizontal commercial water fountain pumps on the market are very complete.

 

Attentions When Using The Commercial Water Fountain Pumps2

 

When using a commercial water fountain pump, there are several points that need special attention:

1. Equipment grounding:

In order to ensure the personal safety of the fountain when it is used, the state's mandatory standard for submersible pumps is to adopt protective grounding. Otherwise, if the pump casing leaks electricity, the water near the pump outlet and the water surface of the reservoir will be charged, which seriously endangers the safety of humans and animals. , Will also cause a waste of electrical energy.

If the metal casing of the commercial water fountain pumps is grounded in accordance with the national standard grounding body (grounding resistance is not greater than 4Ω), in the event of leakage, the current flows through the pump casing, the ground wire, the grounding body, the ground, the working ground wire of the transformer, and the power supply to form a closed circuit. The circuit, once the leakage current is too large, is to make the protective device of the pump work-the fuse is blown or the air switch is tripped, and the power of the commercial water fountain pumps is automatically disconnected.

2. Install leakage protector:

Once a leakage crisis occurs, as long as the leakage value exceeds the operating current value of the leakage protector, which usually does not exceed 30mA, the leakage protector will work, disconnect the switch, and stop the fountain.

3. Power on when the power supply voltage is abnormal:

As a submersible pump, too high or too low voltage will increase the temperature of the pump body, shorten the life of the pump, and even burn out. Now in many places, there are long low-voltage power supply lines or excessively high voltage at the beginning and end of the line. The problem. Therefore, when the fountain is running, the operator should always pay attention to the power supply voltage value. When the power supply voltage value is 10% higher than the rated voltage or 10% lower than the rated voltage, and the current exceeds 20% of the rated current, the machine must be stopped immediately to avoid abnormal voltage. Power on.

4. The motor rotates in the opposite direction:

Although some fountain submersible pumps can double water in the forward and reverse directions, because the reverse water output is small and the current is large, the long reverse time will also damage the motor.

5. Avoid long-term overload work
