balancing rig

With the improvement of the requirements in high efficiency, low cost and environmental protection of petroleum industry, vehicle-mounted pressure balancing workover rig has an important engineering value.

随着石油行业对修井作业高效率、低成本和环保要求的不断提高，本文涉及的车载式不压井修井机具有重要的工程应用价值。

Because of the large dimension and the small adaptation range of existing slips, which can not meet the requirements of structure and function of vehicle-mounted pressure balancing workover rig.

现有的通用卡瓦机构由于结构尺寸大、适应范围小等因素不能满足车载式不压井修井作业的结构与功能要求。

Finally, in the balancing test rig and the project site, the field balancing test system was use to balancing the rotor and was fully tested.

最后，分别在转子动平衡实验台和工程现场中，使用开发的现场动平衡测试系统对转子进行平衡，对系统进行全面测试。
