平衡载荷 balancing load
- 承载链直接承受平衡载荷,可大幅度减小主传动链的受力。
The bearing chain bears the equilibrium load to reduce the force on the main drive chain to a great degree. - 主传动链与承载链将悬点载荷分解为换向抽汲载荷与平衡载荷。
The main drive chain and the bearing chain divide the polished rod load into reverse pumping load and equilibrium load. - 链结子为换向机构,具有滑动轴承功能,并联循环链和主传动链,把循环运动变为上下往复运动。承载链直接承受平衡载荷,可大幅度减小主传动链的受力。
The chain link is the reverse mechanism, functions as sliding bearing and makes the cycle chain and main drive chain parallel to change the circulation into reciprocation.
