三、电路本文仅对故障较多的电路加以介绍。 1.在机架部分,电器接线图(见图6)上标有电阻R_2。此电阻为消除剩磁用。为了防止回转臂传动电机D_1长期顺、逆转而产生剩磁影响动作,在电枢两端跨接电阻R_2(RXY_c51 Ω 10W),以此作负载限流,借以消除剩磁,以利正常运转。如果R_2的一端脱落,表现在钻机回转臂转动时,当松开按钮开关AN_9,回转臂不能马上制动,而是要继续向前转动,这样回转臂转动的角度就不准了。
Third, the circuit This article only fault circuit to be introduced. 1. In the rack section, the electrical wiring diagram (see Figure 6) marked resistance R_2. This resistor is used to eliminate residual magnetism. In order to prevent the rotating arm drive motor D_1 long-term cis, reversal and residual magnetization effect of action, across the armature across the resistor R_2 (RXY_c51 Ω 10W), as the load current limiting, in order to eliminate residual magnetism for the normal operation. If one end of R_2 falls off, it means that when the rotary arm of the drilling rig turns, when the button switch AN_9 is released, the rotary arm can not be braked immediately. Instead, the rotary arm should continue to rotate forward so that the rotation angle of the rotary arm is not allowed.
