Q: What is the most effective way to stay updated on your pump’s condition?
A: Manual inspection
Q: What is the most effective way to stay updated on your pump’s condition?
A: Remote online monitoring
Q: What is the most effective way to stay updated on your pump’s condition?
A: Regular maintenance
Q: What could be the consequences of using an undersized pump in a well?
A: The pump will give too high pressure
Q: What could be the consequences of using an undersized pump in a well?
A: The risk of cavitation is very high
Q: What could be the consequences of using an undersized pump in a well?
A: he pump may not be able to deliver the required
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: The shorter the distance is to the water the less expensive it is to make the borehole and subsequently to pump the water to the surface
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: The shorter the distance is from the surface to the ground water, the better the water quality is
Q: Why is it a good idea to make a well where the groundwater level is as high as possible?
A: A higher level means lower water temperatures and better motor cooling
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: The well driller can try to run the pump at its maximum capacity in short periods of time over a couple of days
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: The well driller can replace the casing with a new one with smaller slots
Q: What can be done to the well if sand continues to enter a well after the well development has been carried out?
A: An additional filter can be installed inside the casing
Q: What is well development?
A: The drilling of a hole in the ground to find groundwater
Q: What is well development?
A: The installation of the well casing in the centre of the borehole
Q: What is well development?
A: A process that ensures that the well’s sand filter has been improved so the well produces clean, sand-free water
Q: What should the minimum flow past the motor be to ensure sufficient motor cooling?
A: 0,5 m/s
Q: What should the minimum flow past the motor be to ensure sufficient motor cooling?
A: 0,15 m/s
Q: What should the minimum flow past the motor be to ensure sufficient motor cooling?
A: There are no specific requirements
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It increases speed and thereby the performance of the pump
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It raises the motor temperature, reducing the lifetime
Q: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
A: It reduces flow and pressure
Q: What may cause friction loss in the pipes?
A: Scaling
Q: What may cause friction loss in the pipes?
A: Poor water quality
Q: What may cause friction loss in the pipes?
A: High water temperature
