The unit of the pump automatic control system is a new domestic automatic control of water supply and drainage, sub-direct start, automatic decompression starting (15kW ~ 200kW) and Y-△ step-down start three categories. According to different needs, set the level control type, pressure control type, temperature control type. Time control type, air conditioning control type. Submersible sewage pump type and fire control type seven types, and has the main circuit short circuit, lack of phase, overload, overcurrent and special pump pump leakage, stator winding over temperature protection. In addition, the various types of single-control, multi-pump main use, standby mutual control type, the main, prepared tile-controlled products are faulty with the main pump automatically cut, standby pump automatically into the water stop, automatic exchange rotation. Ultra water level shutdown alarm and other functions. Widely used in agricultural production, municipal engineering, high-rise building water supply and drainage, fire, spray, booster pump automatic control and air conditioning hot and cold water circulation pump control boiler water and other occasions, but also for other AC motor control and start, Is the ideal supporting the product of various types of pumps.
Control mode: local and remote control
Start mode: triangular step-down start, auto-step-down start, soft start
Number of controls: multiple units
Ambient temperature: -10 ~ +40 ℃ (not frozen)
Air relative humidity: 20% to 90%
Installation: Customized according to customer
Control requirements: any (according to customer requirements)
Main pump switching mode:
Manual switch: manually switch between main pump and spare pump. When the main pump fails, the standby pump will be automatically put into use;
Automatic alternating switch: for the main pump, standby pump need to alternate work occasions, each time, the main, standby pump alternately. When automatic switching is not required, the diverter switch can be selected manually.
Timing automatic switching: for the main pump, standby pump need to switch the work of the regular time, when the main pump to work after the set time period, the timer automatically stop the main pump, start the standby pump to balance the working time of the main pump.
