The roller centralizer product has undergone many changes from its birth to the present. Of course, we have also gained a lot from these changes, which is also an accumulation of experience. However, we still have to pay close attention to the birth speed of new centralizer products, because we have to catch up with the market demand. However, we don't have to worry too much about this problem, because now the centralizer has applied two new application modes.

 These two are thermoset and movable. The movable type is like this: the two parts with the same shape and convex inner wall are connected together, and we can rely on the locking teeth for fastening. The thermosetting type is to inject the centralizer on the sucker rod body. This can reduce the number of times that the sucker rod centralizer is broken, and similar to the usual oil pipe breakage or perforation accidents, the pump inspection cycle is prolonged. It may work better if nylon is used.
When we need to have high requirements on its shock resistance and vibration resistance, we can also make improvements, because the sucker rod centralizer has reserved space for its upgrade in the early stage of design.
