Water pump control cabinet with overload, short circuit, open phase protection and pump body is leaking, motor overtemperature and leakage protection function and the complete status display, and has single pump and pump control working pattern, a variety of main pump switching mode and all kinds of starting mode. Can be widely used in industrial and agricultural production and all kinds of building water supply and drainage, fire protection, sprinkler pipe network pressurization and hvac hot and cold water circulating pump automatic control and other occasions.
Water pump control cabinet typical applications: constant pressure water supply, fire protection, sprinkler, central air conditioning, water supply and drainage, port machinery, machine tool, boiler, papermaking machinery, food machinery, etc.
Water pump control cabinet control type:
1, level control, the control cabinet with high-performance ball float switch, according to the level of high and low change, automatic control of water supply and drainage pump drive and park.
2, pressure control: external electric contact pressure gauge and pressure controller, according to the change of the pipe network pressure automatic open and close pump, this type of application in the drinking water and fire pressurization system.
3, temperature control, external temperature controller, according to set the temperature range of the pump or pump, used in constant temperature, heat exchange system and so on need to temperature control.
4, time control: chassis panel has time setting button and display, the user can control opening and closing of the pump according to the needs of timing, suitable for all kinds of timing or regular intermittent control works.
Pump control cabinet startup mode
Direct start, star triangle step-down start, auto voltage step-down start, soft start and variable frequency start, etc. When using should based on factors such as power supply condition to choose the appropriate way.
Water pump control cabinet function is introduced:
1, fire pump control cabinet
Fire hydrant fire pump control cabinet points with control cabinets, automatic spray with case and fire control cabinet, etc., can be divided into one with a case and two with one case, etc. Pump failure delay automatic standby pump working, the pump by fire hydrant button, water flow in the relay, pressure switch and fire control system, such as control, water anhydrous alarm. With working status (manual, automatic) selector switch, indicator and feedback. Can match the function such as fire inspection.
2 feed water pump, constant pressure water supply control cabinet, life
Feed water pump (constant pressure water supply) life points and liquid level control cabinet, pressure and constant pressure frequency conversion control cabinet, etc., can be divided into one by one case, two with a case and so on. Work spare pump when the pump failure delay automatic input, water pump by water tank water level control, pressure control and remote control system control, constant pressure water supply pipe network pressure is by far the pressure gauge and pressure transmitter detection, after operation 4-20 ma, or 0 to 10 v output to the frequency converter, frequency converter according to the signal adjust pump speed to meet the requirements of the pump flow changes, so as to realize the constant pressure variable feed water, save energy. With working status (manual, automatic) selector switch, indicator and feedback. Pump water anhydrous alarm and automatic shutdown.
3, hot water circulating pump control cabinet
Hot water circulating pump control cabinet can control one or more pumps, generally is one with a case, two as spare, spare pump when the pump fault automatic working, work can also rotate. Pumps controlled by temperature or remote control. With working status (manual, automatic) selector switch, indicator and feedback
