Description
Technical field
The utility model relates to a kind of drainage system, in particular to a kind of frequency conversion drainage system.
Background technique
Drainage system is an important content in Process of Urban Development, and hull-borne influences the life of city dweller
It is very big.Draining pump is the important component of drainage system, has decisive role to the hull-borne of drainage system.Mesh
Before, common drainage system generally passes through water pump and directly extracts the water in puddle out, and the revolving speed of water pump immobilizes, to cause
The waste of electric energy, and pump working meeting frequent start-stop, and staff's execute-in-place is also needed when work.
Utility model content
The purpose of the utility model is to provide a kind of frequency conversion automatic drain systems, so that the revolving speed of water pump can be according to liquid level
Change and change, saves electric energy, prolong the service life.
Purpose of the utility model is realized as follows: a kind of frequency conversion automatic drain system, including frequency converter, PLC control
Unit, Level meter and water pump；
The power input of the frequency converter connects three phase mains, to power for water pump；
The liquid-level probe of the Level meter is arranged in puddle, and Level meter is electrically connected with PLC control unit, uses
To detect the liquid level in puddle；
The PLC control unit is electrically connected with the signal end of frequency converter, to control frequency converter work；
The water pump is arranged in puddle, and the power end of water pump is connected with the power output end of frequency converter, to by puddle
Interior water discharge.
When utility model works, detection data is sent to level sensing again after the water in liquid-level probe detection puddle
Instrument, Level meter will send PLC to after data processing, PLC instructs frequency converter to work, works as water with pre-set program
Liquid measure in hole is few, and PLC will allow water pump with very low rotation speed operation, until the liquid measure in puddle sees the bottom；When the liquid in puddle
Measure more, PLC, which will allow, water pump middling speed or to run at high speed.Compared with prior art, the beneficial effects of the utility model are, this reality
Prolonged with novel by using PLC cooperation Level meter, Frequency Converter Control pump working so as to avoid water pump frequent starting
Long life；And the full Intelligent unattended of control process is on duty；Electric energy is also saved simultaneously.The utility model can be used in draining.
As further limiting for the utility model, between the signal end and PLC control unit of the frequency converter, PLC control
It is connected by signal wire between unit processed and Level meter, between Level meter and liquid-level probe.So that signal transmits
It is more reliable and more stable, guarantee the stability of pump working.
As further limiting for the utility model, between the three phase mains and frequency converter, between frequency converter and water pump
It is connected by three-phase power line.So that electric energy supply is more stable.
In order to enable the service life is longer for the power supply line between connection frequency converter and water pump, between the frequency converter and water pump
Three-phase power line periphery is coated with waterproof layer.
Detailed description of the invention
Fig. 1 is the utility model control principle block diagram.
Specific embodiment
A kind of frequency conversion automatic drain system as shown in Figure 1, including frequency converter, PLC control unit, Level meter and
Water pump；The power input of frequency converter connects three phase mains, to power for water pump；The liquid-level probe setting of Level meter exists
In puddle, Level meter is electrically connected with PLC control unit, to detect the liquid level in puddle；PLC control unit and frequency converter
Signal end electrical connection, to control frequency converter work；Water pump is arranged in puddle, the power end of water pump and the power supply of frequency converter
Output end be connected, to by puddle water be discharged, between the signal end and PLC control unit of frequency converter, PLC control unit with
It is connected by signal wire between Level meter, between Level meter and liquid-level probe, between three phase mains and frequency converter,
It is connected by three-phase power line between frequency converter and water pump, three-phase power line periphery is coated with waterproof between frequency converter and water pump
Layer.
When utility model works, detection data is sent to level sensing again after the water in liquid-level probe detection puddle
Instrument, Level meter will send PLC to after data processing, PLC instructs frequency converter to work, works as water with pre-set program
Liquid measure in hole is few, and PLC will allow water pump with very low rotation speed operation, until the liquid measure in puddle sees the bottom；When the liquid in puddle
Measure more, PLC, which will allow, water pump middling speed or to run at high speed.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing creative labor can be special to some of which technology
Sign makes some replacements and deformation, these replacements and deformation are within the protection scope of the present utility model.
