钻机的调试及工作要求
   Rig Debugging and Job Requirements
 
钻机安装好后，调试是非常重要的，是保证钻机工作性能良好的。钻机在公司内试车时，已将各系统压力调整好，在现场一般不需要重新调试。
After rig is installed, debugging is very important in ensuring that it works properly. When an in-house trial run is conducted for the rig, each system pressure must have been adjusted, and generally require no further adjustment on the spot.
 
 调试工作要求
 Debugging Requirements
 
1.   调试时油温应在20-40之间进行，最佳温度为40-50C。
       For the debugging purpose, the oil temperature should be between 20℃and 40℃, and the optimum temperature is 40-50℃.
2.   在调试压力时，必须要加负载(阻力)。注意：不要误将空载阻力当做负载，否则数据不准，易发生机械和安全事故。
       For the purpose of pressure debugging, load (resistance) must be applied. Note: Do not misuse no-load resistance as load, or inaccurate data will be obtained, which is prone to mechanical and safety accidents.
3.   按一般常规调试某一个液压阀的溢流阀压力时应按下列程序进行：
       The pressure of the overflow valve on a hydraulic valve should be debugged conventionally in accordance with the following procedure:
3.1 松开溢流阀上的固定螺母；
       Loosen the fixed nut of the overflow valve;
3.2 将调整螺栓松开退回几圈；
       Loosen the adjustable bolt by several threads;
3.3 在测试压力的管路中建立一个液压负载(阻力)：例如：将液压油缸达到行程终点，或将液压马达管路用一个适当的螺塞堵上受压力的管路。
       Build a hydraulic load (resistance) in the pressure testing pipeline: for example: bring the hydraulic cylinder to an end of stoke, or fill the pressurized pipeline of hydraulic motor with a suitable screw plug.
3.4 缓慢拧紧阀上的溢流阀，观察压力表数值，压力逐渐升高，达到规定数值。
       Tighten the overflow valve slowly, and observe the pressure gauge reading. The pressure will rise gradually to a specified value.
3.5 拧紧调整螺栓上螺母紧固好，观察压力表有无变化。
       Tighten the nut on adjustable bolt securely, and observe the change of pressure gauge.
