This set of components can rotate to the back leakage discharge hole and pump the bottom of the alignment.
这样可以使整套部件旋转至背板漏液排出孔与泵的最底端对齐。

In the course of transmission, mud pulse signal mainly disturbed by drilling pump, engine in the bottomhole, air bladder contained in mud and movement of drilling equipment.
泥浆脉冲信号在传输过程中主要受钻探泵、井底动力机、泥浆中的气泡及活动钻具的干扰;
