Frequently Asked Questions (FAQ)
1. What are the main components of these pumping units?
The main parts include the Motor, Reducer box, Crank, Connecting rod, Walking beam, Support frame, Base seat, and Brake device.
2. What is the difference between Type C and Type B pumping units?
Type C and Type B are different models of conventional pumping units. Type C generally offers a wider range of rated rod loads (up to 47,000 lbs) and stroke lengths, making them highly versatile. Type B units are engineered with structural variations designed to meet specific operational requirements, handling rod loads up to 13,300 lbs.
3. What does "Rated Rod Load" mean in the specifications?
The Rated Rod Load indicates the maximum weight or force that the pumping unit's rod string can safely handle during continuous operation. It is a critical factor when selecting the appropriate unit for your well's depth and fluid volume.
4. How is the stroke length measured and what are the options?
Stroke length is measured in inches (in) and represents the total travel distance of the polished rod during one cycle. Depending on the model chosen, Type C units offer stroke lengths ranging from 20 to 240 inches, while Type B units offer lengths from 23 to 64 inches.
5. What type of gearboxes are used in these pumping units?
These pumping units are equipped with highly durable positive speed gearboxes. The rated torque for these gearboxes is measured in inch-pounds (in.lbs) and varies depending on the specific model selected to ensure optimal power transmission.
