Blow molding machine hydraulic oil temperature sensor temperature too high can appear too high can stop. When hydraulic overload with alarm and shutdown and revealed. Can show a normal pressure demand and too high and too low. In too high and too low alarm and show. Can use the button to control total air intake and demand. And when a door opened in arbitrary can block the total intake is as long as the ability to restart after reset manually acknowledged. Safety should be put in the top position at the top that is in a closed blow molding machine do their opened a door of the hydraulic pump is to break it to suspend the servo oil pump as long as the ability to restart after reset manually acknowledged. The hydraulic oil level requirements have below liquid level sensor can alarm and show. Get to the point. Now blow molding machine, hollow blow molding machine, blow molding machine usually two hydraulic ?
