砂轮机的故障主要由振动引起的。振动不仅缩短砂轮机的使用寿命,甚至导致砂轮机不能正常使用。新安装砂轮机的振动一般不外乎以下三种原因。 (1) 动、静不平衡引起的 这可以通过转动部分做动、静不平衡试验得知。一般新购置的砂轮机较少出现这类问题,否则就是产品质量问题了。 (2) 安装问题 安装质量可以通过安装质量标准检查控制,只要严格按要求安装也是没有问题的。 (3) 共振引起的振动 这是由于外干扰频率与砂轮机固有频率接近或相等所引起的。这类振动常常出现确不易被判断,可处理起来并不难,只要在砂轮机
Grinder failure is mainly caused by vibration. Vibrations not only shorten the service life of the grinder, and even lead to the grinder can not be used normally. The vibration of the newly installed grinder generally nothing more than the following three reasons. (1) dynamic and static imbalance caused by this part of the rotation can be done by static and dynamic imbalance test that. General newly purchased grinder less such problems, otherwise it is the product quality problems. (2) Installation problems Installation quality can be checked by installing quality control standards, as long as strictly in accordance with the requirements of the installation is no problem. (3) Resonance-induced vibration This is caused by the fact that the external interference frequency is close to or equal to the natural frequency of the grinder. Such vibrations often appear to be difficult to judge, which is not hard to deal with, as long as the grinder
