Ko nga tikanga mo te whakakore i nga paera pa

2018-04-24
E toru nga waahanga ka tohua i roto i te tukanga o te whakakore i te whakaritenga me tePona puranga.
one, the regulating and Pona puranga 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 Pona puranga 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.

E rua, he tino taimaha te raupapa whakarite, he iti te kohanga puka, he uaua hoki te hanganga. (hei tauira, ko te nekehanga me te whakarite ture o DN1800 ko te 28T, penei i nga manga me nga raima, pēnei i nga manga me nga parakohe i roto i te wai paipa, he ngawari ki te whakauru i te waaawa me te putanga. me te whakaoti i te raruraru o te whakakorenga i muri i te whakakore i te nekehanga me te whakatikatika i te hiku. Kia taea ai te tirotiro me te whakakoi, me whakauruhia nga hikoiwi 1 i mua o te puera me te muri Ko te hiko (ka tuhia te pungarehu i waenga i te motuka papamuri me te paopao whakaheke) hei tapahi i te wai i roto i nga waahanga o runga me te heke o te awa. Hei whakarite i te rere o te wai me te karo i te hiko o te cavitation, te tawhiti i waenganui i te taraiwa me te whakarite ture me te tuturu papamuri me tutuki te whakaritenga mo te roa o te pipe pai i mua i muri i muri i te paera.
Toru, ko te tohu whakatuwheratanga o te piringa e whakahaere ana i te motuka papamuri me whakawhitia ki te ruma whakahaere e te puoro (i mua o te puera, i muri i te hiko me te rere), a, kei te whakahaerehia te ruma whakahaere e te ruma whakahaere. Ki te whiwhi tohu tohu, ko te rere o mua me nga hiko o muri o te hiko e hiahiatia ana kia pumau. Ko te roa o te paipera he 35 nga wa te roa o te pipe pai, a, i muri i te hiko ka puta te rere ki te whakaputa i te kaha, ka pupuhihia nga mirumiru maha ki roto i te putunga, a kaore te roa o te roa o te ngongo pai e kore iti iho i te 5 wa te roa o te putunga. Tohu.
