Description

Jeden z tych nastawników wykorzystano jako nastawnik war¬ tosci maksymalnej pobieranego pradu. Nastawiany jest on przez silniczek synchroniczny 4 o predkosci obrotowej 1 obr/min, za posrednictwem ciernego sprzegla zwrotnego. Z chwila gdy rzeczywista wartosc pobieranego pradu jest wyzsza od aktual¬ nie zadanej na nastawniku, nastepuje uruchomie¬ nie silniczka 4, który przesuwa nastawnik do po¬ zycji w której wartosc zadana osiagnie wartosc wielkosci rzeczywistej. Stan ten powtarza sie do momentu osiagniecia wartosci maksymalnej pradu, dla danego procesu zmaslania. Drugi nastawnik re¬ gulatora mostkowego 3, wykorzystany jest do usta¬ wiania wielkosci spadku obciazenia, ponizej war¬ tosci maksymalnej, przy której chcemy otrzymac sygnal zakonczenia procesu zmaslania. Z chwila, gdy rzeczywista^Wartosc pobieranego pradu spad¬ nie o wartosc aadana nastawnikiem drugim, na¬ stepuje zadzialanie przekaznika posredniczacego 5 i wlaczenie sygnalizatorów 6, (akustycznego i op¬ tycznego) zakonczenia procesu zmaslania. Sygnal o zakonczeniu procesu moze byc równiez uzyty do automatycznego wylaczenia silnika napedowego masielnicy. 15 20 25 PL PLOne of these adjusters was used as a maximum current draw adjuster. It is set by a synchronous motor 4 with a rotational speed of 1 rpm, via a friction feedback clutch. When the actual value of the drawn current is higher than the current value set on the adjuster, the motor 4 is started, which moves the adjuster to a position in which the set value reaches the actual value. This state repeats itself until the maximum current value for a given choke process is reached. The second adjuster of the bridge regulator 3 is used to set the amount of the load drop below the maximum value at which we want to receive the signal of the end of the soaking process. As soon as the actual value of the consumed current decreases by the value set by the second controller, the intermediate relay 5 is activated and the signaling devices 6 (acoustic and optical) of the end of the fading process are activated. The end of the process signal can also be used to automatically shut down the drive motor of the churn. 15 20 25 EN PL

Claims

1. Patent claim A device for signaling the end of the choke process in periodic churns, characterized by the fact that it consists of a bridge regulator (3), a regulator of the maximum value of the current consumed by the churn motor, an intermediate relay (5), optical signaling devices (6) and the acoustic afterlet end, and the thermal converter (1) converting proportionally the amount of current consumed by the engine (2) of the churn to heat, which changes the resistance of the resistor located inside the converter (1), which is used by the bridge regulator (3), which sets the maximum value, for a given fattening process, of the current consumed by the churn motor (2), and the decrease in the value of this current causes the bridge regulator (3) to turn on the value of the decrease in the value of the drawn current, at which the end of desaturation is switched on, is given by the following the switch of the bridge regulator (3). a7 PZG Zam. 1013-75, pic. 105 + 20 copies Price PLN 10 PL PL
