Kondizzjonijiet għar-riforma tal-pompi tal-pompa

2018-04-24
Hemm tliet punti li għandhom jiġu rreġistrati fil-proċess ta 'bidla fir-regolazzjoni uValv tal-pompa.
one, the regulating and Valv tal-pompa are arranged in a combined way, leaving one valve to reserve several other valves in parallel. The number and type of the shut-off valve after parallel connection are determined, and the circulation capacity is up to Cv standard. In order to ensure the non overflow of the pressure Valv tal-pompa operation, the pressure stabilizing tower should be set up to make the hydrostatic pressure of the water supply system close to the working pressure of the pipe as much as possible to reduce the cost of the project. If the pressure stabilizing tower is set up in the upstream of the pressure regulating and regulating valve, it is sure that the height of the pressure stabilizing tower is higher than the water level of the water inlet. Generally, the height of the pressure stabilizing tower is higher, the investment of the project is increased, and the operation is not convenient, so the pressure regulating and reducing valve is set in the downstream of the stabilizing tower.

Tnejn, il-valv li jirregola huwa tqil ħafna, it-toqba tal-ħruġ hija żgħira u l-istruttura hija kumplessa. (per eżempju, il-valvola li tirregola u tirregola l-pressjoni tad-DN1800 hija sa 28T, bħal fergħat u plastiks, bħal fergħat u plastiks fl-ilma tal-pajp, huwa faċli biex tidħol fil-kavità u fl-iżbokk tal-valv. manhole biex iwettaq manutenzjoni ġenerali, neħħi l-iswiċċijiet, u ssolvi l-problema tar-riforma wara li żżarma l-valvola li tirregola u tirregola l-pressjoni. Sabiex tkun tista 'tiġi kkontrollata u riveduta, 1 valvola tal-farfett għandha tkun issettjata quddiem il-valv u wara il-valv (il-manhole huwa ssettjat bejn il-valvola tal-farfett u l-valv li jirregola l-pressjoni) biex jinqata 'l-ilma fil-pipelines upstream u downstream. u l-valv tal-farfett iridu jissodisfaw ir-rekwiżit tat-tul tal-pajp dritt qabel u wara l-valv.
Tliet, il-grad tal-ftuħ tal-valvola tal-farfett li jirregola l-pressjoni jeħtieġ li jiġi trasferit għall-kamra tal-kontroll mis-sensor (il-quddiem tal-valvola, wara l-valv u l-fluss), u l-kamra tal-kontroll hija kkontrollata mill-kamra tal-kontroll. Biex tikseb sinjal stabbli, il-fluss tal-valvi ta 'quddiem u ta' wara tal-valv huwa meħtieġ li jkun stabbli. Ġeneralment, it-tul tal-pajp huwa 35 darba it-tul tal-pajp dritta, u wara li l-valv jikkawża l-fluss biex jiġġenera enerġija ddawwar, ħafna bżieżaq li għandhom jiġu splodjati huma ffurmati fil-pajp, u t-tul tat-tul tal-pajp dritt mhuwiex inqas minn 5 darbiet it-tul tal-pajp. Grad.
