The Tape Measure can be rolled up because there is a spring inside the tape measure. When the measuring length is pulled out, the length of the ruler and the spring is actually stretched. Once the measurement is completed, the spring inside the tape measure will automatically contract, and the ruler will follow the action of the spring force. Shrink, so the tape will roll up.

Thin oil lubrication device to solve high pressure centrifugal pump shaft bearing problem
In the oil network news: With the high-pressure centrifugal pump running time and equipment aging, high temperature around the pump bearing, burned often appear. In response to this emerging cost phenomenon, 208 oil production team at Hekou Oil Production Plant installed a thin oil lubrication pump for the high-pressure centrifugal pump to force lubricate the front and rear bearings of the pump. The device through the oil back and forth cycle to increase the flow rate to reduce the bearing temperature, to solve the bearing bush phenomenon. With a thin oil lubrication device, the pump remains in good operating condition. Not only save costs, but also ensure the pump open rate.
