185 TECHNICAL APPENDIX 18

186 NPSH The minimum operating values that can be reached at the pump suction end are limited by the onset of cavitation. Cavitation is the formation of vapour-filled cavities within liquids where the pressure is locally reduced to a critical value, or where the local pressure is equal to, or just below the vapour pressure of the liquid. The vapour-filled cavities flow with the current and when they reach a higher pressure area the vapour contained in the cavities condenses. The cavities collide, generating pressure waves that are transmitted to the walls. These, being subjected to stress cycles, gradually become deformed and yield due to fatigue. This phenomenon, characterized by a metallic noise produced by the hammering on the pipe walls, is called incipient cavitation. The damage caused by cavitation may be magnified by electrochemical corrosion and a local rise in temperature due to the plastic deformation of the walls. The materials that offer the highest resistance to heat and corrosion are alloy steels, especially austenitic steel. The conditions that trigger cavitation may be assessed by calculating the total net suction head, referred to in technical literature with the acronym NPSH (Net Positive Suction Head). The NPSH represents the total energy (expressed in m.) of the liquid measured at suction under conditions of incipient cavitation, excluding the vapour pressure (expressed in m.) that the liquid has at the pump inlet. To find the static height hz at which to install the machine under safe conditions, the following formula must be verified: hp + hz (NPSHr +.) + hf + hpv where: hp is the absolute pressure applied to the free liquid surface in the suction tank, expressed in m. of liquid; hp is the quotient between the barometric pressure and the specific weight of the liquid. hz is the suction lift between the pump axis and the free liquid surface in the suction tank, expressed in m.; hz is negative when the liquid level is lower than the pump axis. hf is the flow resistance in the suction line and its accessories, such as: fittings, foot valve, gate valve, elbows, etc. hpv is the vapour pressure of the liquid at the operating temperature, expressed in m. of liquid. hpv is the quotient between the Pv vapour pressure and the liquid s specific weight., is the safety factor. 1 The maximum possible suction head for installation depends on the value of the atmospheric pressure (i.e. the elevation above sea level at which the pump is installed) and the temperature of the liquid. To help the user, with reference to water temperature ( C) and to the elevation above sea level, the following tables show the drop in hydraulic pressure head in relation to the elevation above sea level, and the suction loss in relation to temperature. Water temperature ( C) Suction loss (m),2,7 2,, 7, 1, 21, Elevation above sea level (m) Suction loss (m), 1,1 1,6 2,2 2,7 3,3 Friction loss is shown in the tables Flow Resistance of this catalogue. To reduce it to a minimum, especially in cases of high suction head (over - m.) or within the operating limits with high flow rates, we recommend using a suction line having a larger diameter than that of the pump s suction port. It is always a good idea to position the pump as close as possible to the liquid to be pumped. Make the following calculation: Liquid: water at ~1 C γ = 1 kg/dm 3 Flow rate required: 2 m 3 /h Head for required delivery: 7 m. Suction lift: 3, m. The selection is an 33SV3G7T pump whose NPSH required value is, at 2 m 3 /h, of 2 m. For water at 1 C hp = Pa / γ = 1,33m, hpv = Pv / γ =,17m (,171 bar) The Hf flow resistance in the suction line with foot valves is ~ 1,2 m. By substituting the parameters in formula 1 with the numeric values above, we have: 1,33 + (-3,) (2 +,) + 1,2 +,17 from which we have: 6,8 > 3,9 The relation is therefore verified.

The values given are guideline values which are bound to vary slightly according to the model, especially for gate valves and non-return valves, for which it is a good idea to check the values supplied by manufacturers. 189 TECHNICAL APPENDIX
