Submersible sewage pump model how to choose?

[Asia Fluid Network News] on the submersible sewage pump model choices vary, different types of submersible sewage pump work in different situations. For example, if the work site is small, does not require a large amount of displacement, then you can choose submersible sewage pump and submersible drainage pump. The data is organized to help understand the submersible sewage pump model how to choose? , So you will no longer feel troubled. Submersible sewage pump model how to choose? Submersible sewage pump mainly with a coupling device and mobile two categories. In buildings, submersible sewage pumps, submersible sewage pumps, vertical sewage pumps and self-priming sewage pumps are commonly used. Choose to use the appropriate pump according to the site's restrictions. However, vertical sewage pump and self-priming sewage pump not only covers an area of ​​demand, for the base isolation, self-priming irrigation requirements are set, so fewer people choose to use in the building. In fact, the selection is not difficult. We only need to select the appropriate flow, lift and power on it. Pump flow: Sewage pump flow should be based on the life of drainage design of the second flow to select, when the displacement adjustment, you can follow the life drainage maximum hour flow selected. Example: fire elevator pool drain pump flow is not less than 10L / s. Pump lift: lift height in accordance with the head, pipe loss calculation is confirmed, you can use an additional 0.02 ~ 0.03MPa free head. Note that the suction pipe and outlet pipe flow rate should be controlled at 0.7-2.0m / s. Pump power: If you need to contain a large row of hard to break up the debris, the pump should be selected with the smashing device. If you need to upgrade the sewage containing more fibrous material, the pump you choose should be a large-channel submersible sewage pump. When the pump motor power is greater than or equal to 7,5 KW or outlet diameter is greater than or equal to DN100, the recommended pump fixed auto-coupling device. If the pump motor power is less than 7.5KW or the outlet diameter is less than DN100, it is recommended to use a hose-type installation.Now the submersible sewage pump compact and lightweight, a lot of advantages, more and more people attach importance to, the future of the road A bright. Is used for urban enterprises sewage, irrigation of the good choice. After reading this selection introduction, I believe you already have a few hearts in this regard, will not be confused it!
