dust suppression system regulator
dust suppression system pressure gauge WARNING! The pressure regulator should never be adjusted above 125 psi.
dust suppression system strainer
The dust suppression system regulator (Fig. 22) is located below the breaker power unit on the right side of the machine and is used to control the water pressure to the six spray nozzles located in the hose crossover tray over the breaker shaft. The water pressure to the nozzles is monitored by the dust suppression system pressure gauge (Fig. 18). To increase pressure, turn the regulator handle in (cw). To decrease pressure, turn the regulator handle out (ccw).
The dust suppression system pressure gauge (Fig. 22) is used to monitor the water pressure to the spray nozzles. The gauge should read between 5 and 125 psi.
The dust suppression system strainer (Fig. 22) is located below the breaker power unit on the right side of the machine and is used to filter particles from the mine water supply. The strainer should periodically be flushed to avoid becoming clogged. To flush the strainer, turn the ball valve handle, located on the branch of the strainer body, 90° in-line with the outlet. Allow to flush for approximately thirty seconds to one minute and then close the ball valve handle.
The water solenoid is located beside the regulator/strainer assembly and is used to control flow of water to the six spray nozzles located in the hosed crossover tray over the breaker shaft. The solenoid is controlled by a pressure transducer located in the hydraulic pressure gauge manifold beside the primary valve bank. When the “MAN/OFF/ AUTO” switch on the starter enclosure is set to “AUTO”, the “TRAM/ OFF/CONV” switch is set to “CONV”, and the hydraulic system pressure reaches 1,000 psi, the solenoid will open and allow water to flow through the water/oil cooler and then to the spray bars. The solenoid activation pressure is adjustable through the PLC.
