In close pump outlet valve, open the inlet valve, and can ensure that the water pump " fill " ( level higher than the pump inlet pipeline conditions, pump start-up procedure is: start the motor, when the normal operation of the motor, slowly open the outlet valve, the current gradually increase. But in the unattended operation ( valve ), is also automatically pump, and the pipe diameter and length ( pipe water quality will be great ), such as the motor start fast, to quickly promote the quality of water accelerates ( like train to accelerate quickly ), will make the motor starting current is large, and cause motor trip the damage of mechanical and electrical. The soft start (to add a soft starter circuit ), motor and speed slow, can overcome the above situations, this special control motor speed is slow and soft starter pump soft start.
When direct starting current is 6-7 times, may reach the rated current of the factory, will give the other problems of electric equipment. Using the soft start current is about 2-3 times the rated current. For the water pump, and soft stop, let the water slowly down, eliminate water hammer effect. Simple said is slowly started, slowly stop. This slowly adjusting the time is about 1-60 seconds.
Soft start the water pump control cabinet debugging and use method
Soft start the water pump control cabinet ( cabinet ) control circuit, a automatic control and manual control, also has overvoltage, overcurrent, under voltage, phase lack protection and accident alarm function, the product before use, must according to the electric principle diagram wiring after review, in accordance with the actual requirements of the corresponding motor adjustment element set value, then start.
1, automatic operation: switch on the power, the power indicator light, will switch to " automatic " position, check the control cabinet ( box ) motor control whether the liquid level controller commands. When the liquid level to control the liquid level, the liquid level indicator light shines, limiting control relay corresponding normally open contact is closed automatically, two control circuits are automatically switched on, the motor starting, running lights at the same time. When the water level reached the stop water level, the corresponding indicating lamps lighting, corresponding level measuring instrument limit control relay normally closed contact is disconnected, the two control loop circuit, the motor stops working, running lights go out.
2, manual operation: switch on the power, the power indicator light, will switch to " manual" position, press the start button, the motor starts to run, running lights, press the " stop " button, the motor to stop running, the lights go out.
3, no matter what the control mode, when reaching the limit water level gauge, the water level signal contact, the two control circuit power loss, the motor stops running, and send out sound and light alarm signal. If the accident appeared in the process of motor running, fault indicator light, bell automatic alarm, then, press the stop button, forcing the motor stop working.
