How to use fountain submersible pump for maximum effect
The selection of submersible pump for fountain pump is very important before application. the type of pump should be selected according to the actual situation of water source, operation time and pump water volume etc. Experts in fountain pumps teach you how to use submersible pumps: 1. environmental requirements for use of submersible pumps for fountain pumps
1. the fountain pump has a safe and reliable power supply.
2. the gap between the outlet pipe and the water surface of the pool is smaller than the lift.
3. choose relatively clean water sources.
Ii. start of fountain pump
1, 11 kilowatts of submersible pump promised to start directly, more than 13 kilowatts of submersible pump should be equipped with decompression cabinet, to maintain the safe operation of submersible pump.
2. in order to prevent the rotor of the submersible pump from jumping up instantly and reduce the starting load, when starting the submersible pump, the stroke of the outlet valve should be closed to 3 / 4 ( leave 1 / 4 air gap so as to deflate ) and slowly turn over after starting the water outlet until the operating point of the pump is controlled in the proper position.
3. after the start of the operation, monitoring and observation of water level changes should be strengthened to ensure that the submersible pump operates within the operating range. the submersible pump cannot be put into formal operation until it operates smoothly.
4. after the submersible pump is put into operation for the first time for 5 hours, it shall stop the machine and measure the thermal insulation resistance promptly. its value shall not be less than 0.5mΩ, so that it can be used continuously.
Iii. fountain pump operation
1. the submersible pump of the fountain pump should operate at the planned operating point. the axial force is moderate at this moment. Research on the special pump for fountains found that the pump efficiency was the highest when operating at the planning point. The most economical and reliable.
2. the submersible pump of the fountain pump shall be checked thoroughly every 8 hours for any change in appearance, whether the circuit node is hot, whether the sound is normal, and whether the normal operating current is greater than the rated value of the motor famous brand.

4. before shutting down the submersible pump of the pump fountain pump, in order to prevent the backflow of water. Special pump for fountain reminds you: close the valve when blocking the power supply and start from the beginning for more than 20 minutes.
