System, safety monitoring system and servo drive system composition.Wherein, servo drive system is more crucial portion in whole device
Point, with continuing to develop for science and technology, the servo drive system of existing energy-saving vulcanizer generally uses closed loop feedback control, passes through
The pressure sensor of detecting system oil pressure and the velocity sensor being installed on servomotor do feedback signal to servo-driver.
Due to the increase of sensor, system destabilizing factor is caused to increase, often because sensor fault causes vulcanizer
Stop production, cause economic loss；And the sensor control circuit of sensor and matching is increased due to system, section is result in
Energy type vulcanizer cost is higher.
The content of the invention
The invention aims to overcome the shortcomings of prior art exist, there is provided a kind of vulcanizer without sensor servo
Drive system.
