一般专业的操作人员都会携带专用的液压扳手来进行安装和维修工作。在锁紧的过程中一定要严格按照产品说明书中的规定来操作。在打压的过程中一定要注意两个重点，为了保证机器均匀受力，将其反力杆放置在指定位置。在转动扳手扭动杆时一定要在指定的使用范围之内来进行。而且在操作时要随时观察压力表来得知扭矩力的大小。当第一次紧固操作完之后要将压力归零，将换向阀扳动方向后进行二次紧固。
General professional operators will carry a dedicated hydraulic wrench to carry out installation and maintenance work. In the process of locking must be strictly in accordance with the provisions of the product specification to operate. In the process of pressure must pay attention to two points, in order to ensure that the machine uniform force, the rod placed in the designated position. Must be in the specified range of use when turning a wrench. And to observe the pressure gauge to know the size of torque during operation. After the first fastening operation end pressure to zero, the valve pulling direction after the two fastening.
对于板式换热器来说专用的液压扳手是必不可少的，下面奎赫液压来告诉大家为什么一定要使用专用的液压扳手。
对于一台全新的板式换热器来说要安装的话紧固螺丝必不可少，而出现损坏的板式换热器在维修时也需要重新拆开来进行二次安装。而固定效果是否良好很大程度上决定了机器的使用效率。而使用专用的液压扳手就能够让机器里的板片和夹板能够牢牢地挤压在一起。
For a new plate heat exchanger to install the fastening screw is essential, and the damage of plate heat exchanger in maintenance also need to open the second installation. And the fixed effect is good to a large extent determine the efficiency of the use of the machine. And the use of a dedicated hydraulic wrench to allow the machine in the plate and plywood can be firmly squeezed together.
