The working principle and characteristics of ammonia - filling device
Edit:Lianyungang Mi Lu Luo Pump Industry Co., Ltd   UpDate:2016-06-05

The ammonia injection device consists of a control system and a dosing system. The control system consists of an industrial acidity meter, a regulator, a frequency converter and a control circuit. Dosing system by the dosing pump, medicine box composition.

The sample is cooled by the cooler and the temperature is between 20 and 35 ° C. The pH value of the sample water is measured by the acidity meter. On the other hand, it is displayed in digital form and converted to 4 to 20 mA standard signal output To MPS programmable controller. MPS programmable logic controller to compare the input signal with the given value, according to the results of a certain algorithm for a logical operation, and output the corresponding 4 ~ 20mA current control inverter to change the speed of the pump motor, dosing pump motor The speed of change to control the amount of dosing pump requirements, so that the parameters of the controlled object to run in the best condition. The system has a protective function: when the tank level is low level, a low level contact signal sent to the MPS, MPS will not start dosing pump. When the pressure of the dosing pipe is high, the pressure high signal contact is sent to the MPS, MPS will not start the dosing pump.

1, PH table for the single-chip intelligent instrument, the electrode for the integration of electrodes, reflecting the acidity of accurate. edit

2, the controller for the MPS programmable controller, with a flexible and stable features.

3, the user can choose according to their type of dosing pump with the inverter.

4, the control mode is fuzzy control, can eliminate the large oscillation phenomenon
