Prefabricated sewage lifting pump station

With the development of cities,Prefabricated sewage lifting pump stationWidely used in projects such as sewage upgrading and rainwater drainage. According to on-site requirements, it can be divided intoPrefabricated sewage lifting pump stationRainwater and sewage diversion well pump stations, rainwater pump stations, high flow shaft pump stations, and buried dry pump stations are distinguished by different flow rates, head, and functions. The following are specific differences and applicable scenarios:

Prefabricated sewage lifting pump stationSuitable for residential areas, dormitories, hospitals, and other places ——Used when the terrain makes it difficult for sewage to flow into the pipeline network and prone to sedimentation and pollution. The system includes an inlet gate, an inlet grille (commonly used crushing grille, which can crush sewage and garbage), a control system, and a pump station main body; Select alloy blade open impeller cutting pump for water pump, quantity according to“one in use and one standby”or“two in operation and one standby”to configure.

Rainwater and sewage diversion well pump station: For working conditions such as black and odorous rivers, lake black water, and mixed flow of rainwater and sewage in old residential areas, it can achieve rainwater and sewage diversion, direct discharge of rainwater, and can also detect the water quality and rainfall inside the cylinder, which is intelligently controlled by the control system. The equipment includes a cylinder, a sewage diversion gate, a sewage lift pumpCODOnline water level monitoring device, rain gauge, monitoring system, and hydraulic system; The gate needs to be corrosion-resistant, so it is used304 Stainless steel material, if equipped with a large gate, the cylinder body can also be selected304 Stainless steel, equipped with small gatesGRPThe material cylinder is sufficient.

Rainwater pumping station: used in low-lying areas such as culverts, tunnels, subway stations, etc ——Solve the problem of rainwater not flowing naturally and easily causing waterlogging caused by terrain. The system consists of an inlet grille (commonly used basket grille), a high flow water pump, a control cabinet, gate valves, pipelines, and liquid level devices; Due to the large amount of rainwater flow, a large flow submersible pump needs to be selected, with the quantity according to“two in operation and one standby”or“three in operation plus one standby”to configure.

High flow wellbore pump station: When a single pump station cannot meet the demand for high flow processing, multiple pump stations are connected in parallel and stacked to achieve high flow discharge. Suitable for flood prevention and drainage, as well as scenarios where the flow rate of rainwater in the area is large, it is usually diverted at the inlet cylinder or grille, and connected in parallel by two or more pumping stations to forcefully discharge rainwater into the confluence pool, and finally into the river channel.

Underground dry pump station: suitable for scenarios that require pressurized water supply, reclaimed water reuse, reclaimed water pressurization, and require underground installation to save space. The fiberglass cylinder (anti-corrosion and anti-oxidation) is buried underground, and the system includes a fiberglass cylinder, a non negative pressure unit, and a control system; The inlet water is under municipal pressure and is not limited by the ground elevation. The height of the cylinder can accommodate the non negative pressure unit. Due to being buried underground, the design needs to consider the risks of water leakage and heavy rain flooding, so internal drainage pumps need to be installed for timely drainage.
