Operation Principle
The transducer controls the frequency convention motor, directly linked to the reducer (by belt), to mobilize the pinion, which drives the long ring rack. When the motion achieves the top and bottom, the pathway guiding role would lead the pinion lateral moved for reversing directions, which leads the rack to do reciprocating motion. All these procedures done, the gas and oil pumping work continues.

Main Structure
The physical structure of Long Ring Rack Pumping Unit / Water Pumping Gas Production Unit is shown as right picture. Mainly include:
>>Diving System (Pinion, Long Ring Rack, Reducer and Track Box, etc.)
>>Balance Syatem(Balance Slide Block, Long Ring Rack, Balance Roller, etc.)
>>Hanging System (Roller, Belt, Roller Cover and Beam Hanger, etc.)
>>Body (Channel Beam and Coamings, Window and Ladder, etc.)
>>Base (Body Hinges, Adjustable Screw, Base Hinges, etc.)
