Constant pressure water supply equipment supporting submersible pump installation

Constant pressure water supply equipment supporting submersible pump installation
1. There are three sets of submersible pumps in this cabinet, the power of submersible pump is 18.5KW. Can be manually or automatically switch from SA1 (hand automatically switch) for manual or automatic control switch. When the manual function is selected, the automatic operation of the controller is stopped. The manual indicator lights. Manual start button SB1, No. 1 submersible pump starts, press the button SB2, the No. 1 submersible pump stop. Start up the motor for a short time during commissioning and check that the steering of the submersible pump motor is correct. Manual start button SB3, No. 2 submersible pump start, press the button SB4, the two dive pump stop. Debugging the same to check the pump motor steering is correct. No. 3 submersible pumps and so on. When automatic control is selected, the controller will automatically adjust the controller according to the external pressure. When the SA1 (manual automatic switch) is selected, the inverter will switch the frequency and pump frequency. When the external pressure continues to be less than the preset lower limit, the controller will switch the working frequency pump to work frequency, the next standby pump will enter the frequency conversion operation and maintain the pipeline pressure to the set value.
In the automatic state, when the external pressure continues to be greater than the set upper limit to a preset time. The controller will cut off the first work-frequency pump. Until the pipe pressure reaches the setting range. When the external protection function is connected, if the tank water level is lower than the set minimum water level, or when the pipeline pressure exceeds the allowable value, the pump will be shut down and restarted after reaching the starting condition. The above protection can also be installed according to site conditions.
2. Industrial frequency conversion design. Does not change the power frequency loop. Dual standby, redundant control to meet the application of various operating conditions.
3. Need to install a pressure sensor, the range is 0-1MP (0-10KG)
4. The main circuit cable shall be provided by the purchaser.
