Fountain Pump The use of submersible pump machinery

Fountain pump before the use of the submersible pump is very important to choose, should be based on the actual situation of water and working hours and pump water requirements to select the pump model. Fountain special pump expert to teach you how to use submersible pumps:

1. Fountain pump submersible pump use of environmental requirements

1, a safe and reliable power supply.
2, the outlet pipe and the pool water surface to be less than the head.
3, to choose a relatively clean water.

Startup

A submersible pump of 1,11 kW allows direct start-up. 13 kW or more submersible pumps should be equipped with buck starting cabinet. To protect the safe operation of submersible pumps.
2, in order to avoid the submersible pump rotor moment on the channeling and reduce the starting load. Submersible pump start should be the exit valve travel to 3/4. (Leaving 1/4 of the air gap. In order to deflate) to be activated after the water slowly opened. To control the pump operating point in the appropriate location.
3, start after the start operation. Monitoring and observation of water level changes should be strengthened. Ensure that the submersible pump in the range of operating conditions. Until the submersible pump running smoothly before put into operation.
4, submersible pump first put into operation 5 hours later. Stop the rapid measurement of thermal insulation resistance. Its value is not lower than 0.5MΩ. Can continue to use.

3. Run

1, the fountain pump submersible pump should work in the design work point. At this time the axial force is moderate. Fountain dedicated pump study found that the design point of work the highest pump efficiency. The most economical and reliable.
2, fountain pump submersible pump every 8 hours to run a comprehensive inspection. Each instrument has no change. Circuit node is hot. Sound is normal. Normal operating current is greater than the motor nameplate rating.

4. Stop the pump

Fountain Pump Before the pump stops. To prevent water backflow. Fountain dedicated pump to remind you: cut off the power at the same time to close the valve. Restart time interval of 20 minutes or more.
