| Popis: | Aiming at problem that traditional mechanical instrumens and hydraulic control modes cannot meet requirements of safe, accurate and efficient construction of coalbed methane truck-mounted drilling rig, an electric control system for coalbed methane truck-mounted drilling rig was designed. The system is composed of sensors, sub-console, control box and main console. The sub-console collects parameters of diesel engine and realizes control functions such as diesel engine starting and stopping, throttle adjustment and throttle switching. The control box drives solenoid valve of hydraulic system for logical control. The main console is used for driller to observe drilling parameters and operate drilling operations. The field application results show that the system can monitor and display drilling parameters of diesel engine and drilling rig in real time and accurately, and realize logical control of diesel engine operation and drilling rig, which provides guarantee for auxiliary drilling construction and improving drilling quality. |
