Hydraulic pumps 1 and 2 are driven directly by the diesel engine via a flexible coupling. The pressure control panel controls the working pressure to pump 1. This pressure supplies the drilling block's directional valves with oil. general General The hydraulic system on the ROC D5/D7/D9 is an electrical and pilot pressure controlled system. general Hydraulic system. 6 . This pilot pressure also supplies the tramming block’s directional valves with oil and the directional valves for high-speed tramming and winch freewheel. The system comprises 4 hydraulic pumps. The drain cock is used to remove water of condensation or to empty the hydraulic oil tank.Hydraulic system. There is a stop valve that prevents return oil from leaking out through the filler pump. The sensor signal from B143 goes via PLC input X36. The by-pass valve protects the oil cooler from exposing to high pressure. T. Should this drop below a certain level. D-Drain oil is a collection block that collects oil from the various circuits and leads directly to the return oil filter. L-Leakege oil is oil that goes directly to tank for minimum resistance in the circuits. general Return oil and oil cooler The Hydraulic oil tank has a capacity of 260 litres which means that there is always a “stock” of oil in the tank./ drain oil filter 7 . The cooling fan is driven by a hydraulic motor that is supplied with oil from pump 4 at a maximum pressure of 160 bars (D5) or 220 bar (D7). A level sensor (B143) detects the level of hydraulic oil in the tank. The oil cooler cools the hydraulic oil so that the rig can work at full load in ambient temperatures up to 50°C. In addition to storage it serves to separate water and dirt. Temperature sensor (B362) sense the hydraulic oil temperature and the temperature will be shown on the display. The filler pump is used to fill the system. There are two holders with 3 filters in each which filters hydraulic oil from the return.and drain circuit and the oil during filling. The engine will automatically stop if the hydraulic oil temperature exceeds 90ºC.Return oil is a collection block that collects return oil from the various circuits and leads it to the thermostats and to the return oil filter. Thermostats By-pass valve Oil cooler T-Return Check valves Refill pump D-Drain Ventilation filter Drain cock Hydraulic oil tank Return. the diesel engine is switched off automatically. Thermostats ensure that the oil flows through the oil cooler when the temperature is above 40ºC and directly to the tank when the temperature is below 40ºC. There is also a ventilation filter which prevents contaminated air from entering the tank when the hydraulic oil level is changed. Note: This signal is connected directly to the EMS. 7. 5.

ECM ECM (Electronic Control Module) is used for monitoring the engine’s functions and sensors. Electric cabinet The electrical cabinet (A1) contains 17 fuses. the CCU (CAN Control Unit) and the remote control box. Battery and charging The power source for starting the engine is two 12 V/185 Ah batteries that are connected in series. Main fuse The power supply to the electric cabinet is fused by a 60 A main fuse (F300) and a 100 A main fuse (F304). There is a CAN serial communication between the CCU and the remote control box. a CCU and a PLC. The CCU is located in the large electric cabinet (A1) and controls the hydraulic valves for tramming. The ECM stops the diesel engine automatically if a specific fault occurs. The structure of the electrical system is illustrated in a block diagram. of which one automatic circuit breaker that limit the intensity to the various sub-circuits. positioning (boom lift and boom swing) and the winch. general Electrical system. The batteries are connected to the system via a manual battery switch. A specific fault is for example low oil pressure which could cause major damage to the engine. The system consists of two parts. EMS The ECM also indicates specific faults through indicator and warning lamps on the diesel panel and EMS (Electonic Monitoring System) LED-display. general General ROC D5/D7/D9 is equipped with a 24 volt electrical system for monitoring and fault indication. These are charged by a generator. CCU Winch control unit is a system for controlling the winch from the remote control box.and pneumatic valves.

The flow of compressed air passes through a pressure valve to the drill rigs air system. The compressor unit is an Atlas Copco type G106 screw compressor.5 bar with the Caterpillar diesel engine. In the air receiver. the majority of the oil is separated from the air/oil mixture using an oil separator.Compressor Compressor General The built-in compressor is a single-stage compressor. Air Atmospheric Pressure Air Regulating Pressure Air Working Pressure Air/Oil Mixture Oil 16 . The pressure valve prevents the pressure in the air receiver dropping below the lowest working pressure for the compressor (approx. Compressor unit The compressor unit comprises two rotors: a drive rotor and a slide rotor mounted on rollers and ball bearings.8 bar). Its normal working pressure is 10. The rotors are lubricated with oil that is injected and mixed with the air.55. This increases efficiency since the oil forms a seal between the rotor blade and the housing. The air is mixed with injected oil and goes directly from the compressor to the air receiver. The over centre valve also prevents oil returning into the system. This oil is removed by a separator unit. Air flow The intake air is drawn through the air filter and an over centre valve to the compressor unit. to ensure the correct function of the oil system. The gear ration is 1. 2. even when the air outlet valves are open. The drive rotor is driven by the diesel engine and transfers power to the slide rotor. The air/oil mixture leaves the compressor unit and returns to the air receiver. The oil that is collected at the bottom of the oil separator returns to the oil system through a cleaning line that has a flow limiter. The control system also includes a load valve that is activated by a switch on the diesel control panel. The system switches off the diesel engine if the compressor temperature exceeds +120°C. The compressor unit has an oil platform at the bottom of the sleeve. The compressor also has a temperature indicator switch (B366). The lower part of the air receiver acts as an oil tank. Air Atmospheric Pressure Air Regulating Pressure Air Working Pressure Air/Oil Mixture Oil Regulator system The compressor control system comprises a regulator valve. where the oil is separated from the air. The air pressure means that the oil is transported from the air receiver through the oil cooler and oil filter to the compressor unit.Compressor Cooling and oil systems Oil is used for lubrication. The load valve allows the diesel engine to warm up before engaging the compressor. cooling and sealing is injected through a hole in this oil platform. 17 . sealing and cooling. Note: A thermostat valve bypasses the oil cooler when the oil is below 70°C. The bearings are lubricated by oil injected into the bearing housing. There is no oil pump with pressure provided by the air pressure. This valve controls the air volume supplied by the compressor for air consumption whilst also keeping the working pressure within a certain range. Instrument and fault indication The pressure of the compressed air delivered from the compressor can be read from the pressure gauge. which automatically provides indication and displays in plain text on the display that the temperature has risen.
