Common type
Function: To achieve the conventionalsequential control relay-contactor, interlocking, overload, over-current, short circuit protection function, can detect theoil temperature, oil pressure and otherparameters (for use in electric contact thermometerand pressure gauge ), and the corresponding parametersexceed the standard alarmindication.
Features: The main motorand oil pump motor using Y-start, the logic control by therelay - contactor control.
Frequency conversion start +common type
Function: Variable frequency starting, can reduce the machine startupimpact, pushing the number ofspeed and adjustthemachinedrum. A mutual locking, overload, over-current, short circuit protection function, can control the temperature, pressureand otherparameters( for use in electric contactthermometer and pressure gauge), alarm device.
Features: Frequency controlthe main motorand oil pump motor, the logic control by therelay - contactor control.
