Liquid Resistor Starter And Speed Regulator (Lrr)

We are engaged in offering excellent quality Liquid Resistor Starter And Speed Regulator (LRR) to our valuable clients.
Application scope: It is used from the soft start, speed regulation and energy-saving operation of slip ring motors with rated voltage of 415v ~15kv

Main technical parameters:
Initial starting current : 1sta 1.3in (A) speed regulation rates : 2:1 for air blower fan and pump
recommendable range : 60%~90% Nn
Characteristics of impulse suppressing slip Sa 0.12 for rolling machine, based on its working conditions
Energy saving rates : a Y30%(average value) for air blower fan and pump
Normal working temperature of variable liquid resistor : 0~70A C
Protection level : IP20, IP30

Working principles:
As for motors with loads such as air blower fans or pumps, speed regulation and energy saving can be achieved by changing resistance value of the variable liquid resistor that is connected in series to the rotor circuit of motor: the less resistance, the faster speed; the motor reaches its full speed when the resistance value reaches zero.

A heat circulation system is devised to circulate the liquid so as to prevent the temperature of the liquid from excessive rise. A central control unit can be adopted to realize remote monitoring and operation. Its features are convenient control panels, convenient operations and high reliability.

Clients can avail this Liquid Resistor Starter And Speed Regulator (LRR) at industry leading prices from us.
