Sk water ring vacuum pump sometimes gets stuck in normal work. What causes this? Xiaobian has summarized some knowledge in this regard. Let's go and have a look.For some reason, the motor is overloaded or even unable to rotate. Usually, this phenomenon is called "jamming". The causes of SK water ring vacuum pump jamming are: the spring is damaged, resulting in uneven force on the rotating blade; Improper assembly makes a part stressed; Due to the loss or damage of the filter screen at the air inlet, external dirt, metal chips and glass chips fall into the pump cavity.In addition, the gap between the end face of the rotor, rotating disc and the end cover of SK water ring vacuum pump is too small, the friction heating makes the rotating disc elongate or overheat, and the friction is too tight. In addition, the hardness of the rotating disc is too large, which is rolled with the burr, resulting in deep scratches on the end face, and the end face is stuck after sintering. When the shaft and shaft sleeve are too tight, the lubricating oil circuit is blocked, and the pump will be stuck due to mutual adhesion and grinding.
