1. The submerged sewage pump must have vertical equipment on the cover plate of the liquid tank, and it is not allowed to be placed obliquely.
2, the submerged sewage pump with a manual pump, reflect on whether the pump can be stuck, and reflect on whether the vortex direction of the submerged sewage pump motor can be consistent with the pump pleading to turn.
3. Submerged sewage pump must be immersed in the liquid, and it is forbidden to take off the liquid and idle.
Second, the structural characteristics of submerged sewage pump:
1. Submerged sewage pump adopts serial multi-faceted centrifugal sealing equipment for pumps, which completely overcomes the phenomena of running, running, dripping and leaking except the packing seal and mechanical seal of traditional pumps. Submerged sewage pump is an ideal equipment to replace various original long-axis submerged pumps, submersible pumps and submersible sewage pumps.
2. During the operation of the submerged sewage pump, the sealing equipment does not rub or wear, and the service life of the submerged sewage pump is more than ten times longer than that of similar products.
3. The principle that the submerged sewage pump is transplanted with a vacuum pump, and its self-priming performance is stable and reliable. Especially, the electric air control valve is selected, and the submerged sewage pump truly realizes one-time drainage and lifelong self-priming.
4. The submerged sewage pump has the advantages of small vibration, low noise, sensitive movement, simple disassembly, easy installation and no need for anchor fixing.
5. Submerged sewage pump has superior automatic control function.
