管子旋转器可减少杆泵送故障

管道,在一个良好的良好中产生的平均值杆泵系统,代表了井的第二大投资。每天,泵送单元上的每一条行程都会导致管中的磨损。卒中杆上下移动。特别是对于偏离井,杆总是倾向于躺在管道的底部。因此,在泵送单元的每个行程上,杆戴在管道的金属中的路径,将成为管道中的孔的路径。

管磨损:

在每分钟10次行程的典型泵送良好中,杆将每天抵靠管子14400次。这种磨损最终会导致管道故障。A common tubing failure is termed a “tubing split” and normally will be thin on one side of the tubing’s internal surface (about 20% of the tubing’s circumference) and can be detected by pinging with a hammer, cutting open the tubing, or running a thumb inside the tubing to feel for the thin area. The outside of the tubing will normally have a “tubing split” where a thin crack 1 to 5 inches long runs along the longitudinal axis of the tubing as shown in the following figure.
