Analysis And Elimination Of The Causes Of Start-up Faults in Drilling Rigs

Some rotary drilling rig customers may experience start-up failures when preparing for construction. This type of failure is mainly manifested as the starter motor not moving when the key switch is turned to the start position. There are many reasons for this failure. When we encounter this situation, we need to investigate step by step to find the key to the problem. Today, our rotary drilling rig manufacturer will share with you the analysis and troubleshooting of the causes of start-up failures in rotary drilling rigs.

Based on our years of experience as a drilling rig manufacturer, the lack of movement of vehicles in Qidong City is mainly due to the following reasons. Severe battery depletion or internal sulfurization caused by; Damage to the key switch or starting relay; Poor contact between the battery and the starter motor, such as loose connections, oxidized terminals, etc; The suction and pulling coils of the starting motor are burnt out. Some time ago, a customer experienced this kind of malfunction. After our after-sales personnel explained and investigated, it was caused by a quality problem with the starter relay, which resulted in the starter motor's suction coil heating up for a long time and being damaged; The improper wiring of the power cord caused a sudden change in local resistance, which accelerated the occurrence of the fault. After discovering the problem, our manufacturer replaced the starting relay with a new one for the customer, and no problems have occurred so far.
