BL (T) Seri en fe milti-etap santrifujeur ponp (apre sa yo rele ponp) gen anpil karaktè nan efikasite segondè, bri ki ba, operasyon fiks, etc.The ponp mete adopte estrikti ki pa pwòp tèt ou vize a milti-etap, ki fè yon kontra enfòmèl antye, fasil enstalasyon li yo, operasyon li yo ak antretyen pratik.

Kalkil presyon minimòm Inlet
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: Sèt tèt sipò pozitif, m (Valè nan koule maksimòm Q-NPSH koub);
Hf: Piki liy tiyo pèt (Valè nan koule maksimòm pipeline ki koresponn);
Hv: Mwayen vapè presyon, m (Mwayen vapè presyon nan tanperati ki koresponn, mwayen nan default se dlo, jan yo montre nan figi4 sou bò dwat la);
Hs: Sekirite Marge, m, valè jeneral se 0.5.
Calculation result: if H is positive, the pump is installed in suction way, otherwise, it is installed in downdraft way.
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. Mwayen tanperati a wo;
2.The velocity of flow is larger than rated value;
3.Saks tèt se gwo oswa inlet tiyo ki long;
4. Presyon sistèm se ti;
5. kondisyon inlet se move.
Selection Of Pumps
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.
Materyèl ponp
Pump connections
Souvan yo itilize tab mekanik tab konfigirasyon
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. Pump efficiency:
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. Pump material:
Selection of pump connection depend on the rated pressure and pipe work. the pump offer a wide range of ftexible connection such as:

Limit presyon ak tanperati yo montre nan figi.4, presyon an ak tanperati a dwe nan montre nan fig frans lan. 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.
