Fountain pump use four points

Fountain pump mechanical use of the four main points:
Selection before the operation is very important, should be based on the actual situation of the water and operating time and pump water and other needs to select the type.
First, the use of environmental needs
1, a safe and reliable power supply.
2, the outlet pipe and the pool water surface to be less than the head.
3, to select the relatively clean water.
Second, launch
1,11 kilowatts about the fountain pump promised to start directly. 13 kW or more should be equipped with buck cabinet. To maintain the safe operation of the pump.
2, in order to prevent the pump rotor an instant on the channeling and reduce the launch load. Pump should be launched when the valve off to 3/4. To be launched after the water slowly opened. To pump operating point control in the appropriate position.
3, start after the end of the operation. Monitoring and observation of water level changes should be strengthened. Ensure that the submersible pump in the range of operating conditions. After the smooth operation of the pump can be put into formal operation.
4, the pump into operation for the first time after 5 hours. Shutdown rapid measurement of thermal insulation resistance.
Third, operations
1, should be operating in the planning point operating conditions. At this moment the axial force is moderate. Fountain dedicated pump study found that in the planning point of operation the highest pump efficiency. The most economical and reliable.
2, 8 hours per job to check all the time. The appearance of whether or not to change. The circuit node is not hot. Sound is not normal. Normal operating current is not greater than the rated motor nameplate.
Fourth, stop the pump
Fountain pump stopped before. In order to prevent the back flow of water, in the interception of power together to close the valve. Start from scratch more than 20 minutes.
