Offers first-hand insight into the latest experience and research of this cutting edge technology

Mike Gracey was born in Port Arthur, Texas on April 25, 1942 and grew up around the oil refineries & chemical plants in that area. He pursued an engineering education so he could understand how things work because of his fascination with mechanical things like engines and transmissions. After a couple of years at LeTourneau College in Longview, Texas Mike attended night school at Lamar University in Beaumont, Texas while working as a pipe fitters helper in a shipyard. He was able to move into the engineering department where he worked and got married at age 20. Later when returning to school on a full time basis, he worked as a licensed tankerman pumping petroleum products into barges around the Port Arthur and Beaumont area until graduation from Lamar in 1971. By 1973, Mike was working at the National Maritime Research Center (NMRC) in Galveston, Texas and became involved in testing special nozzles and methods for water blast cleaning, surface preparation and coatings. This lead to the more specialized area of high-pressure pumps used for water jetting. Starting in 1976, He worked for high-pressure pump manufacturers and packagers in Texas, Maryland and Michigan to help design and build systems using the technology. Mike presently works for Weatherford International, Inc. using Kobe pumps and their line of industrial pumps to handle chemicals, water, oil products, hot fluids and cryogenics. Mike enjoys writing and public speaking, having published over 40 articles and technical papers.

The trade circulars of some of the makers of the foregoing turbines refer to tests of their wheels made at Holyoke, Mass., at the testing-flume of the Holyoke Water-power Co. (see § 97), where the highest head available is 18 ft. Some of the values of efficiency obtained in these tests not only greatly exceed 80 per cent., but in some cases approach 90 or over. Polishing and smoothing of the surface of the turbine-vanes has been found to increase the efficiency in several instances. In the case of several American turbines taken to Europe and there re-tested, European methods being followed, somewhat lower values of efficiency have resulted. It is thought that the discrepancy is due to the differing modes of measuring the water used. The Jonval type of turbine, or "parallel-flow" variety, is manufactured by R. D. Wood and Co. of Philadelphia, Pa., and is sometimes made "duplex"; that is, the runner is provided with two concentric rings, each containing a set of vanes, the guide-ring being double also. When the supply of water is reduced, one ring alone is brought into action without sacrifice of efficiency. As already mentioned, the firm of Kilburn, Lincoln and Co., at Fall River, Mass., manufacture an outward-flow turbine of the Fourneyron type. See § 75 and Figs. 17, 18, 19. 87. American Turbines.

Not illustrated. 1905 Excerpt: ...view of the water end of a pump, showing the position of the valves during a quick reversal in the direction of the arrows, which illustrates the position of the valves corresponding to high speed. The valves in a pump, like almost every other detail in the operation of machinery, do not act instantaneously, but require time to reach the seats. When pumps run at high speed the piston will move a considerable distance, while the valves are descending to their seats, and water flows back into the pump cylinder until the valves are tightly closed. The valves will remain in the raised position shown in Fig. 191 until the piston stops at the end of the stroke, and under high speed the piston will reach the position on the return stroke indicated by the dotted line L by the time the valves are closed. The cylinder will be filled up to this point with water from the delivery chamber so that no vacuum can be formed until after the piston reaches this position. The volume of water that can be drawn into the cylinder must necessarily be represented by the cubic inches of space, minus the quantity which flows back during the time the valves are closing. It will thus be seen that the actual volume of water discharged is considerably less than a cylinderful, and the difference, whatever it may prove to be, is called, and is due to slippage. Fig. 190 represents the same pump running at a comparatively low speed. It will be noticed that the valves have not been raised as high as in Fig. 191, because.a longer time being allowed for the discharge of the water, a smaller orifice is sufficient. It will be seen also that the piston, moving at a lower velocity, cannot travel as far in Fig. 190 before the valves seat, and consequently a vacuum can be created in the cylinder earl...

The single suction is used for clear water only, while the double suction will pass everything that enters the suction pipe--see engravings. When the pump is located above the water, it has to be primed before it will raise water. For these purposes an ejector, or exhauster, is frequently employed, which will exhaust the air and draw water up from the required depth. The arrangement of the ejector is illustrated at A, in Fig. 496, and is the smallest and most convenient contrivance that can be used for this work. It is screwed into the highest part of the pump, and is connected by a separate steam pipe to boiler. In a short time after turning on steam, the pump will be primed, the pump remaining stationary during the operation of priming. To prevent air returning through the discharge pipe, a check valve, B, is used. For larger pumps a gate valve is generally employed here. A foot valve fitted with a strainer to keep out obstructions likely to clog the pump should be used as it keeps the pump primed and ready for immediate use. The general form of the blades is of great importance in this type of pump, because the water is driven through the fan partly by the pressure of the Fig. 494. blades on the water and partly by centrifugal force. The ratio which each of these forces bears to the other varies in the same pump, depending upon the proportion the speed bears to the height of it. With low lifts and high speed the water is discharged with but little rotary motion, the resistance to the outward motion of the water being so small that the oblique action of the blades is sufficient to effect the discharge without imparting to the water the same speed of rotation as is given to the fan.
