Energy-saving intelligent prefabricated pump station

Abstract

The invention relates to an energy-saving intelligent prefabricated pump station. The energy-saving intelligent prefabricated pump station comprises a barrel body, a liquid level meter, a first waterpump, a second water pump and a frequency conversion control cabinet, wherein the first water pump and the second water pump are mounted at the bottom of the barrel body, the liquid level meter is installed inside the barrel body, and the frequency conversion control cabinet is mounted at the top of the barrel body. The energy-saving intelligent prefabricated pump station has the beneficial effects that by additionally arranging the frequency conversion control cabinet, the frequency conversion operation of the water pumps is realized; and by arranging multi-gear liquid levels of the liquid level meter, water pump frequency increasing can be controlled, the liquid level in the barrel body is guaranteed to be constant, and the stable operation of the water pumps in the efficient area all the time is realized. The economic cost is greatly saved, and the energy-saving intelligent prefabricated pump station is stable, reliable, simple in structure, convenient to operate, economical and practical.

Description

technical field [0001] The invention relates to the technical field of urban water supply and drainage, in particular to an energy-saving intelligent prefabricated pumping station. Background technique [0002] With the development of urbanization, the urban population is increasing, and the urban infrastructure construction is also accelerating development, especially for the treatment of sewage, rainwater and industrial wastewater. The prefabricated pumping station that came into being solved a lot of problems Sewage can be collected and then discharged in a concentrated manner. There are various types of pumping stations in the existing market. However, their water pumps are all started at power frequency, and the distance between the stop pump liquid level and the start pump liquid level is large. During the operation of the water pump, it is easy to cause the overpower of the water pump, causing the motor to burn. Moreover, the water pump cannot always operate in the hi...

[0002] With the development of urbanization, the urban population is increasing, and the urban infrastructure construction is also accelerating development, especially for the treatment of sewage, rainwater and industrial wastewater. The prefabricated pumping station that came into being solved a lot of problems Sewage can be collected and then discharged in a concentrated manner. There are various types of pumping stations in the existing market. However, their water pumps are all started at power frequency, and the distance between the stop pump liquid level and the start pump liquid level is large. During the operation of the water pump, it is easy to cause the overpower of the water pump, causing the motor to burn. Moreover, the water pump cannot always operate in the high-efficiency area, resulting in an increase in equipment operating costs
