John Tonkin and Associates. February 23, 2016. SYSTEM HEAD CURVES PART 2. John Tonkin and Associates. February 23, 2016. A few years back, I posted an item on system curves. During a recent energy audit of a river pump station (3 X 600kW units) the vital importance of system curves was, yet again, clearly demonstrated. This station was an interesting one. Designed and installed in the early/mid fifties the pumps and one of the motors were on the wrong end of sixty years old! There was a brass plate on th...
SUCTION SPECIFIC SPEED PART 1 (NSS) — John Tonkin and Associates
http://www.jtatraining.co.za/blog/2011/9/5/suction-specific-speed-part-1-nss.html
John Tonkin and Associates. September 5, 2011. SUCTION SPECIFIC SPEED PART 1 (NSS). John Tonkin and Associates. September 5, 2011. Part 1: NSS practical aspects and calculation. During a recent visit to a large chemical plant, I was intrigued by the unusually loud knocking noise which was emanating from three reasonably large (350kW) cooling water end suction pumps. A non-technical colleague who was with me at the time even remarked that the noise was unusual. Getting back to the NSS, the Hydraulic insti...

My NPSH (required) is better (lower) than yours. At first glance the answer is obvious, of course! Figure 2). This is fertile ground for the formation of cavitation with all the vibration, noise and metal removal associated with this condition. As was shown in part one of this series, Nss numbers higher that 175 i...

ENERGY, CASH AND PUMPING SYSTEMS PART 2 — John Tonkin and Associates
http://www.jtatraining.co.za/blog/2014/3/13/energy-cash-and-pumping-systems-part-2.html
John Tonkin and Associates. March 13, 2014. ENERGY, CASH AND PUMPING SYSTEMS PART 2. John Tonkin and Associates. March 13, 2014. The point was made that the only constant in life is change! How do they affect the energy consumed, Mean Time Between Failures (MTBF), plant reliability and finally, the total cost of owning the whole system? A bad selection process that saw the installation of a significantly oversized pump. Large changes in flow rates due to changes in processes or system demand. Inflows int...

A Friend
Thursday, November 25, 2010. Poem - Thanks to a Friend; our special journey. To Raymond Kwek;. Our Journey, My Dearest Friend! Were the blessing that was never expected. Who came to my life one ordinary day. Without hesitations nor expectations when it first started. For it was supposed to be nothing but a casual day. In my humble household, you were received. With open arms, and hearts, and mind. Accepted you like an old friend, though we never were,. Trust in God, was all that matter.
