不管是运用卷板机的任何一个大小企业或类似卷板机厂家的工厂这种设备都必须要以防在加工呈现的走漏以及尘埃的落入都必须要设备有密封设备。卷板机液压体系中起着密封效果的元件，即密封件，卷板机液压体系中的密封件是用来避免流体或固体微粒从相邻结合面间走漏以及避免外界杂质如尘埃与水分等侵入机器设备内部的零部件的资料或零件，卷板机液压体系中的密封件外漏会形成作业介质的糟蹋，污染机器和环境，乃至引起机械操作失灵及设备人身事故。

No matter is any size enterprises use rolling machine or similar machine manufacturers to the factory this equipment must be in order to prevent the leakage and dust processing equipment must fall into a sealing equipment. A sealing effect of the components of the hydraulic system of bending machine, namely seals, sealing parts of the hydraulic system of bending machine is used to avoid the fluid or solid particles from the adjacent joints and leakage from external impurities such as dust and water into the machine internal parts of materials or parts, seals for hydraulic system of coil in the operation of medium leakage will form waste, pollution and environmental machinery, and even lead to malfunctioning machinery and equipment for personal accident.

卷板机液压体系中的密封件作业的可靠性和运用寿命是衡量液压体系好坏的一个重要指标。除空隙密封外，都是使用密封件，使相邻两个巧合外表间的空隙控制在需要密封的液体能经过的最小空隙以下，卷板机液压体系中的密封件在触摸式密封中，一般分为自封式压紧型密封和自封式自紧型密封也称唇形密)封两种，可是，卷板机液压体系中的各种密封其功能影响要素是不同的，就像三辊卷板机它的密封其实还，受到了温度压力以及存在的前言的不同影响。

The reliability and service life of the seal operation in the hydraulic system of the bending machine is an important index to measure the quality of the hydraulic system. In addition to seal gaps, are the use of seals, minimum spacing of two adjacent to make the gap between control in need of coincidence appearance of sealing liquid can pass below the seal in touch type seal machine in the hydraulic system, generally divided into self sealing pressure type sealing and self styled self tightening type sealing lip is also called letter two, but close), a variety of hydraulic system in the rolling machine sealing factors and its function is different, like the three roller bending machine it is sealed by pressure, temperature and different effects exist in the.
