Working principle

The drive head is driven by AC motor, and the power is transferred to oil pump rod by belt and gear box, then the oil pump rod brings the down-hole pump operation torque.

Features

1. Patent technology is used in the gear box, it solved the problem of lubrication leakage from the seal of input and output shaft.

2. In the well head seal patent technology of overhead mechanical seal is used, what extends service life of the seal, which is more than 1 year, and is more convenient for maintenance and replace.

3. The patent technology of anti- counter rotating is used. After the drive head stops, it will not counter-rotate. The torque of counter-rotating can be released by anti-counter rotating device safely.

4. The drive head is designed according to the standards, what makes it convenient for maintenance on-site, and keeps mechanical efficiency high and failure rate low.
