Thuba's latest activity

TThuba replied to the thread Flow inconsistence.thats correct, the pumps are being repurposed. So by the fact that the pump operating at very high head and low flow, it means we would...
-
TThuba replied to the thread Flow inconsistence.Lets assume l am pumping water, that comes to a pump at 1000kg/h and the pump adds a pressure of 5bars, hence leaving a pump at 6bars...

TThuba replied to the thread Flow inconsistence.its a centrifugal pump, and the discharge valve is fully open
-
TThuba replied to the thread Flow inconsistence.Assuming l pump a volume of 2m3/h from a pump, l expect that to be constant in system through continuity equation. Only pressure should...

TThuba replied to the thread Flow inconsistence.yes we use a flowmeter dedicated to our product, soybean oil corrected for S.G. and viscosity at given temperature

Tl have a pump rated at 4m3/h and 35m head. lt pumps edible oil through an economizer and the to dearator with some nozzles. From the...

TIt's not a question of 'should you' half the rpm; if you go from a 2 pole to a 4 pole, you WILL half the rpm, that's what the number of...
-
TThuba replied to the thread pumps with different kw rating.oh unbelievable indeed, l replied with confusion, my bad. rpm= frequency×120/number of poles, technically 4 poles cant have 3000rpm. l...
-
TYou don't have a choice. If you replace a 2 pole motor with a 4 pole motor it will run at half the speed. Half the speed for a...

TThuba replied to the thread pumps with different kw rating.Ok thank you all for your valuable information, and l was just moving around the plant and l made an observation on the pumps. And l...
-
TThuba replied to the thread pumps with different kw rating.So for the 2 motors, if l place a flowmeter and a pressure gauge downstrean the pump; volumetric flowrate will be the same, but gauge...
-
TThuba replied to the thread pumps with different kw rating.Thanks, l am replacing 2 pole motor with a 4 pole motor, hence l was wondering l should half the rpm too?
-
TThuba replied to the thread pumps with different kw rating.also the one with a smaller impeller diameter has a higher capacity of 10m3/h
-
TThe kW rating is a measure of what power is required for the flow and head as specified on the datasheet. Notice that the impeller...
