Calculation Of minimum Inlet Pressure
If the pressure in pump is lower than the vapour pressure of medium, cavitation will occur, which will affect the performance of pump. To avoid the cavitation and ensure the pump inlet has a minimum pressure, maximum suction head should be calculated as following:
H = Pbx10.2-NPSH-Hf-hv-Hs
Pb: Atmospheric pressure, bar (In close pipeline system, it can be considered as the system pressure );
NPSH: Net positive suction head, m (Value at maximum flow of Q-NPSH curve);
Hf: Piki liy tiyo pèt (Valè nan koule maksimòm pipeline ki koresponn);
Hv: Medium vapour pressure, m (Medium vapour pressure at corresponding temperature, the default medium is water, as shown in figure4 on the right );
Hs: Sekirite Marge, m, valè jeneral se 0.5.
Kalkil rezilta: si H pozitif, se ponp lan enstale nan fason pou aspirasyon, otreman, li enstale nan fason dekouraje.
Note: It is not necessary to do above calculation under general conditions. Only when we use pump in the following situations do we need to calculate the H:
1. Medium temperature is high;
2.The vitès nan koule se pi gwo pase valè rated;
3.Suction head is big or inlet pipeline is long;
4. Presyon sistèm se ti;
5. kondisyon inlet se move.
Seleksyon nan Ponp
Seleksyon ponp yo ta dwe baze sou:
Devwa pwen nan ponp lan.
Dimensional data such as pressure loss as aresult of height differences,friction loss in the pipework,
Pump efficiency etc.

1. Devwa pwen nan ponp lan:
From a duty point it is possible to select a pump on the basis of the curve charts shown in "performance curves/technical" data.2. Done dimansyon:
Lè gwosè yon ponp sa yo dwe pran nan kontablite: • Obligasyon koule ak presyon nan pwen trase la. "Pèt Pèt kòm yon rezilta nan diferans wotè." Pèt friksyon nan tiyo a (Hf) (Refere nan Fig.1) Li kapab. "Pi bon efikasite nan pwen devwa estime a." NPSH valè. "Pou kalkil valè NPSH a, gade tablo korespondan tablo.3. Efikasite ponp:
Anvan yo detèmine pwen efikasite ki pi bon an, operasyon an nan ponp lan bezwen idantifye. Si ponp lan espere pou opere kòm pwen devwa a menm, Lè sa a, chwazi yon ponp BL ki opere nan yon pwen devwa ki koresponn ak efikasite ki pi bon nan ponp lan.Kòm se ponp lan ki menm gwosè ak baz la nan koule ki pi wo a posib, li enpòtan toujou gen pwen an devwa sou bò dwat la sou koub la efikasite (ak) nan lòd kenbe efikasite segondè lè koule a desann.
4. Materyèl ponp:
Selection of pump connection depend on the rated pressure and pipe work. the pump offer a wide range of ftexible connection such as:

The limits of pressure and temperature are shown in the following fig.4,the pressure and temperature must be in the shown in the fig. 4.
When the pump is operating in the place where ambient temperature is higher than 40℃ or altitude is higher than 1000m,the output power of motor P2 will decrease because of poor cooling caused by low air density.Therefore, in that case,the pump should be equipped with high-power motor.
