Correct
01.
Q: By how much does the supply voltage decrease before the motor contactor stops the pump?
A: More than 10 %
Correct
02.
Q: Which of these isn’t a key dry-run protection benefit for the installer?
A: He doesn’t have to worry about water bursts
Correct
03.
Q: How does the integrated dry-running protection work?
A: It automatically shuts down the pump if water shortage is detected.
Correct
04.
Q: Why is it important to protect the pump from over- and under voltage?
A: Because large variations in power supply will damage the motor over time.
Correct
05.
Q: What must the supply voltage lie between in order for the SQ/SQE pump to deliver a flow of water?
A: Between 150 V and 315 V
Correct
06.
Q: The 3” SQ pump is obviously ideal for new boreholes but where can it also be used?
A: In original 4” boreholes where sediments over the years have narrowed the hole.
Correct
07.
Q: What is the most commonly used starting method for motors in 4” conventional pumps?
A: Direct on line
Correct
08.
Q: What is the benefit of a slow increase in speed?
A: It keeps the motor current low
Correct
09.
Q: How many times higher than nominal speed does the motor current reach during the first milliseconds?
A: Seven times higher
Correct
10.
Q: Is the SQE pump able to provide constant pressure?
A: Yes.
