Wireless remote speed regulation system for sewage lifting pump

Abstract

The invention relates to a wireless remote speed regulation system for a sewage lifting pump, which is characterized by comprising a wireless receiving device, a single chip microcomputer control unit, a digital potentiometer control unit and a control signal amplifying unit, wherein the wireless receiving device is connected with the single chip microcomputer control unit; the single chip microcomputer control unit is connected with the digital potentiometer control unit; the digital potentiometer control unit is connected with the control signal amplifying unit; the control signal amplifying unit is respectively connected with a frequency converter a, a frequency converter b, a frequency converter c and a frequency converter d; the frequency converter a is connected with a lifting pump a; the frequency converter b is connected with a lifting pump b; the frequency converter c is connected with a lifting pump c; and the frequency converter d is connected with a lifting pump d. The wireless remote speed regulation system has the advantages that the artificial speed regulation of the sewage lifting pump is transformed into the remote automatic speed regulation; the traditional cable speed regulation control is transformed to the wireless speed regulation control; the university of frequency converter speed and the high-precision regulation control are realized; and the speed regulation control is simultaneously carried out on a plurality of lifting pumps.

Description

technical field [0001] The invention relates to an adjustment system, in particular to a wireless remote speed adjustment system for a sewage lifting pump. Background technique [0002] At present, the discharge of sewage in industrial enterprises is relatively high, so the environmental pollution is relatively serious, and the sewage cannot be treated well, and the wastewater cannot be allocated selectively according to the water quality of the sewage pumping station, and it cannot provide a source for the sewage treatment to meet the discharge standards. Guarantee, the speed adjustment of the sewage lift pump in the sewage pipe network pumping station is mostly manual adjustment mode at present, the work is cumbersome, and the work is increased. In the sewage speed adjustment, the frequency converter is very important. The frequency converter has been widely used for speed regulation. There are usually three ways of speed regulation, method 1 is through the operation panel...

[0002] At present, the discharge of sewage in industrial enterprises is relatively high, so the environmental pollution is relatively serious, and the sewage cannot be treated well, and the wastewater cannot be allocated selectively according to the water quality of the sewage pumping station, and it cannot provide a source for the sewage treatment to meet the discharge standards. Guarantee, the speed adjustment of the sewage lift pump in the sewage pipe network pumping station is mostly manual adjustment mode at present, the work is cumbersome, and the work is increased. In the sewage speed adjustment, the frequency converter is very important. The frequency converter has been widely used for speed regulation. There are usually three ways of speed regulation, method 1 is through the operation panel of the inverter, method 2 is to control the analog signal input terminal of the inverter, method 3 is through the communication interface of the inverter, and the speed regulation of method 1 can only be done manually The speed regulation of mode 3 is carried out by wired method, and the speed regulation method cannot be used universally. In order to solve the above problems, a new technical solution is specially provided
