Technical Field

The invention relates to the technical field of urban water supply and drainage, in particular to an energy-saving intelligent prefabricated pump station.

Background

Along with the development of urbanization, cities and towns are more and more populated, the development of town infrastructure construction is accelerated, the treatment of sewage, rainwater and industrial wastewater is particularly important, the prefabricated pump stations which are produced by transportation solve a great problem, the sewage can be collected and then concentrated and discharged, various types of pump stations are arranged on the existing market, however, all the water pumps of the pump stations are started at power frequency, the distance between the pump stopping liquid level and the pump starting liquid level is large, the water pump overpower is easily caused in the operation process of the water pump, the motor is burnt, and the water pump cannot always operate in a high-efficiency area, so that the operation cost of equipment is increased.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides an energy-saving intelligent prefabricated pump station, which is realized by the following technical scheme: an energy-saving intelligent prefabricated pump station comprises a barrel, a liquid level meter, a first water pump, a second water pump and a variable frequency control cabinet, wherein the first water pump and the second water pump are arranged at the bottom of the barrel, the liquid level meter is arranged inside the barrel, the variable frequency control cabinet is arranged at the top of the barrel, as a preferred technical scheme of the invention, the liquid level meter is provided with liquid levels with different gears, each liquid level corresponds to a water pump operation mode, as a preferred technical scheme of the invention, the variable frequency control cabinet can change the frequency of the first water pump and the second water pump according to the liquid level change, so that the liquid level in the barrel is basically kept at a constant liquid level, when the pump station is used on site, only the variable frequency control cabinet needs to be electrified, when the pump station normally operates, the water level in the barrel is always kept at a low liquid level, when the water inflow is increased, the frequency of the water pumps is increased, the invention has the beneficial effects that: according to the invention, the variable-frequency control cabinet is additionally arranged, so that the variable-frequency operation of the water pump is realized, the liquid level meter is provided with multiple levels of liquid levels, the frequency increase control of the water pump can be realized, the constant liquid level in the barrel is ensured, the stable operation of the water pump in a high-efficiency area is realized, the economic cost is greatly saved, and the variable-frequency control cabinet is stable and reliable, has a simple structure, is convenient to operate, and is economical and practical.
