When the rotating equipment is not in use, does it have to be turned? What is the turning cycle? What are the precautions in this regard?
I do half a circle here every day
I have one class here, one class at a time. hehe! Three times a day.
Reply 3# yuhongtao05 Too often. The pumps were damaged. Ours is once a week, and some pumps are said to need to be installed once every two weeks.
Reply 4# Jiujing Jizi pump, will it be damaged when turning? Never seen it.
Reply 5# yuhongtao05 I remember that the pump broke last time. The manufacturer came to the scene and said that we had broken the pump plate. I thought that we used to do pumping every Monday, Wednesday, and Friday too often. Later, we changed it to once a week, and some even once every two weeks. Haha, I think it’s funny too haha
Reply 6# Jiujing Jizi Haha, I used to do it once a week, but many pumps were broken. Either there is abnormal noise, or the shaft seal is leaking or stuck.
We crank the car once a day. The cranking usually takes a few more turns, and then the relative position of the shaft changes by 180 degrees.
If the cranking disc does not move, there are several situations: first, debris blocks the impeller or bearing, second, the pump inlet pressure is too high, and third, the inlet liquid is viscous. I think the cranking should not be done in any of these situations. Professional maintenance personnel should be consulted before cranking. The turning cycle of our factory stipulates that it must be turned once every 8 hours, one turn each time
A disk is required, once a week, the axis rotates 180 degrees
It must be plated. Our policy is once a week. If it is a large equipment, turn it 180° once a month to prevent shaft deformation.
