复合材料全自动液压机是一种用作工作介质的特殊液压油，由主机和控制机构两部分组成。复合材料成型液压机的主要部分包括机身，主缸，顶出缸和液体填充设备。 如果发现复合材料成型液压机的操作无响应，该怎么办？ 这种情况的原因是什么？
1. Wear
During the movement of mechanical parts (such as hydraulic valve core, valve sleeve, valve body, etc.), conflicts continue to occur during use, which will cause the size and shape of the parts and the surface quality to change and fail. The wear or deformation of the solenoid valve core will cause the internal leakage of the valve, thereby reducing efficiency, and dirt is easy to enter the gap or deformation, thus constituting the mechanical valve core of the valve core. If the fit clearance between the spool and the valve hole is too large, a pressure shock will occur. The wear of the pilot valve of the pressure reducing valve will make the operation of the valve unstable and even unable to adjust the pressure. The speed control valve pilot cone valve (or pilot small gate valve) is damaged, the seal is not tightly closed, and the pressure cannot be adjusted without problems. The one-way throttle valve (speed control) check valve parts are worn and the seal is not firm. Some oil flow will flow out through the check valve, thereby affecting the sensitivity of the speed control.
2. Fatigue
Working under long-term variable load, yellowing in the hydraulic solenoid valve will cause fatigue, causing yellowing to loosen, shortening the yellowing time or all cracks; the valve core and valve seat will also fatigue, causing cracking, shedding or other damage. All of these may cause the valve to fail. When the main spool of the safety valve or the tension spring of the pilot valve are fatigued or damaged, no system pressure is required. If the extension spring of the directional valve is too soft or too short, it will affect the operating direction of the spool valve and the normal reset, so that the system cannot operate normally.
3. Deformation
In the process of extrusion molding and use, when the external load shear force exceeds the tensile strength of the hydraulic solenoid valve parts of the fully automatic hydraulic press, the parts will be deformed and cannot be used without problems. When the valve body of the pressure relief valve is twisted or deformed, the movement of the valve body becomes unstable, and the system pressure becomes unstable. The bending deformation of the spool of the unloading valve will slow down the posture of the spool and slow down the process of changing the system from throwing pressure to high pressure or from pressure to throwing pressure support. The tortuous deformation of the spool of the reversing valve will make it difficult to perform the action of the reversing valve normally. Warm reminder, poorly processed parts can also cause parts deformation. For example, the deformation of the oil circuit board formed by tightening the machining screws of the directional valve parts will cause the valve core to be blocked.
4. Corrosion
Hydraulic oil is mixed with excessive moisture or acid. After long-term use, it will corrode the relevant parts in the hydraulic valve, causing it to lose its due accuracy and malfunction.
