Research on Matching of Rotary Motor Buffer System of High Speed Drilling Rig

对高转速钻机回转马达缓冲系统进行研究,分析了高转速动力头启停瞬间马达A口、B口压力流量特性,结合ZDY1000G钻机回转马达负载特性,提出回转马达缓冲回路。利用AMEsim软件动态模拟增加缓冲回路前后,马达A口、B口压力流量特性。同时通过软件模拟,优化参数匹配。最后通过试验验证了参数设计的合理性。

Study on the buffer circuit of power head motor of high speed drilling rig, analyzes the characteristics of the pressure and flow rate of the motor A and B port at the start and stop of the high speed power head. Combined with the ZDY1000G dynamic head motor buffer circuit,the AMEsim software was used to simulate the dynamic characteristics of the A and B port of the motor. At the same time ,through the software simulation, optimize the parameters matching. Finally, the rationality of the parameter design is verified by experiments.
