在橡胶薄板,胶带等的制造过程中加压成形的情况其产品的厚度必须一定。 在轧辊上用不同程度的力加压 需要控制厚度,使用何服阀控制轧辊之间的间距。轧辊间距是用差动变压器检测的,与别的设定器的值做比较运算,然后,把放大了的信号送至伺服阀。伺服阀把油源的油压按信号流向可动轧辊的油缸 控制轧辊间的距离与给定值相同。 In the case of press-forming during the manufacture of rubber sheets, tapes, etc., the thickness of the product must be constant. In the roll with different degrees of pressure to control the thickness of the need to control the use of service valve to control the spacing between the rollers. Roller pitch is detected with a differential transformer, compared with the value of other setters, and the amplified signal is sent to a servo valve. Servo valve to the hydraulic oil pressure signal flow to the movable roller cylinder control roller distance with the given value.
