The reclaimed water system that is used for textile technology
Technical field
The utility model relates to the Weaving device technical field, specifically a kind of reclaimed water system that is used for textile technology.
Background technology
In the existing reclaimed water system, only on the pipeline between pond and the workshop reservoir, set up a water pump, this water pump is controlled by soft initiator.But existing reclaimed water system can't change the duty of regulating water pump according to the pressure in the pipeline, makes water pump waste a large amount of electric energy, thereby has caused the increase of cost of production.Therefore, design is a kind of can be vital according to the reclaimed water system that is used for textile technology of the variation of the pressure in pipeline adjusting pump rotary speed.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and providing a kind of can change the reclaimed water system that is used for textile technology of regulating pump rotary speed according to the pressure in the pipeline.
In order to achieve the above object; The utility model comprises workshop reservoir, water pump, pressure sensor, programmable logic controller, soft initiator, frequency converter and pipeline; It is characterized in that: at water pump two of the two ends of water pump one pipeline parallel connection, pressure sensor is located on the pipeline between water pump one and the workshop reservoir, and pressure sensor is connected with programmable logic controller; Programmable logic controller is connected with an end of soft initiator and frequency converter respectively, and the other end of frequency converter is connected with water pump two.
The utility model is compared with prior art; The pressure value that adopts programmable logic controller monitor force sensor to record also passes through the rotating speed of Frequency Converter Control water pump two; The rotating speed of water pump can be changed when regulating according to the pressure in the pipeline; Pressure in the pipeline is controlled at realizes constant pressure water supply about 0.25Mpa, thereby saved the electric energy that water pump consumed, reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Referring to Fig. 1,1 is the pond; 2 is the workshop reservoir; 3 is water pump one; 4 is water pump two; 5 is pressure sensor; 6 is programmable logic controller; 7 is soft initiator; 8 is frequency converter.
The specific embodiment
Combine accompanying drawing that the utility model is done further describes at present.
Referring to Fig. 1, the utility model comprises workshop reservoir, water pump, pressure sensor, programmable logic controller, soft initiator, frequency converter and pipeline.At water pump 24 of the two ends of water pump one 3 pipelines parallel connection; Pressure sensor 5 is located on the pipeline between water pump 1 and the workshop reservoir 2; Pressure sensor 5 is connected with programmable logic controller 6; Programmable logic controller 6 is connected with an end of soft initiator 7 and frequency converter 8 respectively, and the other end of frequency converter 8 is connected with water pump 24.
The utility model is when work; Pressure sensor 5 is transferred to programmable logic controller 6 with the pipeline pressure numerical value between pond that monitors 1 and the workshop reservoir 2; The signal of telecommunication that programmable logic controller 6 will receive pressure value changes into analog current signal and is transferred to frequency converter 8; Frequency converter 8 is according to the rotating speed of the analog current signal control of pump 24 that receives; The rotating speed of water pump 24 can be regulated according to the variation of the pressure in the pipeline, the interior pressure of pipeline is controlled at realizes constant pressure water supply about 0.25Mpa.
