液压试井车及其基本参数计算

针对试井车绞车采用机械驱动或机械加液压联合驱动方式所存在的缺点，指出试井车应当采用液压驱动方式。着重介绍了液压驱动方式的传动原理和液压系统主要技术参数的计算与校核。实践表明，试井车采用液压驱动，不仅能克服机械驱动或机械加液压联合驱动存在的缺点，而且结构简单，工作可靠，噪音小。

Hydraulic well testing truck and calculation of its basic parameters

In light of the shortages existed in a mechanical drive or mechano-hydraulic compound drive well testing truck, the author points out that the well testing truck should use the hydraulic drive and emphatically introduces its transmission principle and the calculation of the main technical parameters of the hydraulic system. Practice shows that the well testing truck with hydraulic drive system can not only overcome the shortages existed in that with mechanical drive or mechano-hydraulic compound drive, but it is also characterized by simple structure, reliable work and low noise.
