The system is specifically designed for tire retreading vulcanizing machine to control operation of mold opening/clamping cylinder and driving cylinder. It is different from hydraulic system for tire sizing vulcanizing machine.
High pressure and low pressure pumps are applied in the system, realizing fast no-load operation and slow pressured operation. Advance relief valve is installed in head port of the driving cylinder, reducing impact and concussion during return stroke of the cylinder. Pressure sensor is also installed to monitor pressure during loading and maintaining, sending out signals and reinforcing pressure to ensure the level of compression.
