Since the running speed of geophysical prospecting drilling rig engine changes very fast under different working condition, throttle valve which completely controlled by manual setting cannot meet these changes again, so the engine often be in the state of over-speed running and severe mechanical wear. A kind of automatic regulation device of drilling rig was developed to solve this problem by author of this paper. The design and working theory have details in this paper.

随着工况和钻机负荷的变化,物探钻机发动机的转速波动很大,而完全靠人工手动控制发动机节气门的开度已不能适应发动机转速大幅度频繁波动的要求,常导致发动机超速运转,磨损严重,耗油增大。针对此问题,本文作者自行研制出了一种石油物探钻机自动调节装置,该装置的实现方案及其各部分电路工作原理在文章中有详细介绍。

The rotary speed of the engines on geophysical prospecting drilling rig fluctuates with the change of the drilling condition and load on the rig. To control the opening of the throttle valve of the engine manually cannot be adapted to the demand of rotary speed fluctuation. Thereby a automatic speed regulation device is developed. The device realize the automatic control of the rotary speed of the engine by means of the ignition signal. The design scheme of the device is presented, and the working principle...

The rotary speed of the engines on geophysical prospecting drilling rig fluctuates with the change of the drilling condition and load on the rig. To control the opening of the throttle valve of the engine manually cannot be adapted to the demand of rotary speed fluctuation. Thereby a automatic speed regulation device is developed. The device realize the automatic control of the rotary speed of the engine by means of the ignition signal. The design scheme of the device is presented, and the working principle of each electric circuit is expounded. Application shows that the automatic speed regulation device has good performance.

随着钻井工况和钻机载荷的变化 ,物探钻机发动机的转速波动很大 ,而完全靠人工控制发动机节气门的开度已不能适应发动机转速大幅度频繁波动的要求 ,对此 ,研制了用于石油物探钻机的转速自动调节装置。这种装置利用发动机的点火信号实施发动机转速的自动控制。首先 ,将点火信号通过整形电路变成频率信号 ,然后进行频压变换 ,其电压与转速为线性关系 ,该电压与设定电压 (预期转速 )相比较 ,用比较输出的状态控制伺服电动机的转动自动控制节气门的开度 ,从而实现转速控制。华北油田物探公司两个地震队试用取得了满意的效果
