Description

Technical Field

[0001] This utility model relates to the field of power plant sewage pump technology, and in particular to an automatic water filling device for sewage pumps. Background Technology

[0002] During power plant operation, a large amount of wastewater containing impurities is generated, including wastewater from the circulating cooling water system, slurry wastewater from the desulfurization and denitrification system, wastewater from unit maintenance, and domestic sewage. If this wastewater is not discharged in a timely manner, it can easily cause problems such as overflow of the collection tank, soaking of equipment foundations, and corrosion and blockage of pipelines. At the same time, according to environmental regulations, power plant wastewater must be collected and treated centrally before being discharged in compliance with standards. The sewage pump continuously transports wastewater from the collection tank to the treatment system to ensure that there is no stagnation in the wastewater collection process. It is the core equipment for achieving closed-loop wastewater treatment and avoiding environmental penalties. Its operational reliability is directly related to the continuity of power plant production and the ability to control environmental risks.

[0003] Currently, the mainstream sewage pumps in power plants are mainly centrifugal sewage pumps, which work on the principle of centrifugal force to transport water: before starting, clean water needs to be injected into the pump casing through the water injection pipeline to expel the air in the pump and make the impeller fully contact the water; after starting, the motor drives the impeller to rotate at high speed, forming a centrifugal force field in the pump casing, which draws the water in the suction pipe into the pump body and pressurizes it to the target area through the outlet pipe.

[0004] The technical defects exposed in the actual operation of existing sewage pump units seriously affect their operating efficiency and stability. Specifically, the priming capacity is insufficient. Due to problems such as wear of the check valve sealing pair and leakage of the water injection pipeline interface, the priming water remaining in the pump casing is prone to slow loss after shutdown. When restarting, the lack of water in the pump causes a "water shortage" phenomenon, resulting in the pump running dry and unable to pump water. Manual refilling is required, which takes a long time for each treatment, significantly reduces the response speed of sewage treatment, and increases the cost of manual operation and maintenance.
