When Hai Tan Pump selected the sewage pump, the key issue was the usability and reliability. According to the pump's installation position, liquid delivery, device lift, liquid medium and other conditions to select the appropriate sewage pump.
Flow: The flow of the sewage pump should be selected according to the discharge second flow rate (Unit of measurement: L/s); When there is a displacement adjustment, it can be selected according to the maximum hourly discharge flow, (unit of measurement: m3/h). Head: The head of the blowdown pump is determined according to the lift height after calculating the pipe loss.
If the medium to be transported is mixed liquid containing some solid medium (such as silt), this problem makes the sewage pump in the motor load capacity, bearing arrangement, pump body seal and other requirements than the general pump, in general Select self-priming sewage pump or submersible sewage pump. When selecting and ordering, be sure to understand the suitability of the sealing and load carrying capacity of your selected sewage pump.
Drain pumps used in buildings include submersible sewage pumps, submerged drainage pumps, vertical sewage pumps, and horizontal sewage pumps. The vertical sewage pump and the horizontal sewage pump require the installation of earthquake-isolation foundations and occupy a certain space, so they are less used in buildings.
In buildings where the site is small and the displacement is not large, submersible sewage pumps and submerged sewage pumps may be preferred. The submerged sewage pump can generally be used in more important places. Its overall structure is compact, small in size, low in noise, easy to move, and easy to install. The energy-saving effect is remarkable. It is easy to overhaul, and it is not necessary to build a pump room. It can work in the water and greatly reduce the project cost.
Some points to note
In the public building facilities, a standby pump shall be installed in accordance with each unit of the drainage pool, which shall be operated alternately in peacetime so as to reduce the long-term load operation of the pump and increase its service life.
When the sewage with a larger medium is to be extracted, the submerged sewage pump outlet pipes in different collection tanks should not be combined and discharged. Taking into account the submersible sewage pump to enhance the inclusion of large debris, the submersible sewage pump with a crushed device. When lifting sewage containing more fiber, use a cutting device or a large-channel submersible sewage pump.
When general waste water is extracted, the discharge pipes of the submersible sewage pump of different collection tanks may be combined and discharged according to actual conditions.
When two or more pumps share a single outlet pipe, valves and check valves shall be installed on the outlet pipe of each pump. When a single pump drain may produce backflow, a check valve should be provided. Pressure drainage is not allowed to be combined with gravity drainage pipes in buildings.
