High-pressure pump operation safety technology process
May 30, 2024
1. Check reducer tank, high pressure pump oil level and emulsion tank water level is in the provisions of the oil level and water level. 2. Check the safety valve, pressure gauge, electric contact pressure gauge, water level gauge, liquid level indicator is sensitive and correct; pressure gauge, safety valve calibration once a year, the safety valve regularly exhaust test to prevent the valve core adhesion and Valve hole blocked. 3. Check the pump parts, the valves, solenoid valves, pipes, etc. are good, may not have leakage, leakage, oil spills, check the electrical connection zero (ground) line is solid and reliable, stop pump more than a week, to measure the main motor Insulation is good; check the hydraulic press contact signal is correct and reliable. 4. Open the pump sequence: (1) check the pump, water tank (gas) and pipe on the valve, water suction valve, circulation valve, all in the open position, open the high-pressure pump pump discharge valve and lubrication Pump cooling water valve; (2) start the lubricating oil pump, running for 1 to 2 minutes, the oil pressure is 0.15 ~ 0.2 MPa, until the indicator light shows normal, start the high pressure pump main motor; (4) After the high-pressure pump is operating normally, close the solenoid valve of the circulating valve and plug in the power plug. When the water level rises to above level 4, close the valve of the lowest liquid level solenoid Switch, the water level rose to 7 (according to pump room design can also be issued in advance "can work" signal) to the hydraulic press issued a "can work" signal, the hydraulic press to work. 5. When opening and closing the valve, - stand on the side of the valve stem and slowly rotate. 6. Do not leave work at work, closely monitor the control instrumentation and water level indicator is normal, such as the emergence of fake water level, should immediately take measures and every 10 to 15 minutes to check all the equipment tour again, record the operation hourly , Oil temperature, bearing temperature shall not exceed 50 ℃, emulsion temperature shall not exceed 60 ℃, cooling water temperature shall not exceed 40 ℃, the motor temperature shall not exceed the rated temperature rise. 7 found overpressure, immediately unplug the suppress plug, and cut off the total power until the water level down to normal, inform the hydraulic press to stop working. To be repaired back to normal, can continue to work. 8. With soap and water check water (gas) tank, valve, trachea leaks, if condensation frost (water), indicating serious air leaks, should be promptly repaired. To thaw, disable open flame. 9. Found the following circumstances, press the "emergency shutdown" ammonium button, immediately shut down and shut off the valve to be closed, the hydraulic press issued an "emergency stop" signal. (1) In the case of overpressure, overtemperature, when adopted measures can not come down; (2) There is abnormal noise, vibration; (3) Manometer, electric contact pressure gauge, liquid level indicator is not correct or failure (4) A sudden serious water leakage can not be blocked; (5) Solenoid valve control failure does not work. 10. Stop the pump in sequence: (1) Immediately after receiving the "Stop Required" signal from the hydraulic press, send back to the hydraulic press the signal "Can stop"; (2) Replenish the water tank to above level 7; (3) (4) Cut off the pump power, are not allowed to stop the pump with a load; (5) After the high-pressure pump stops running, cut off the lubricating oil pump power supply, turn off the oil cooling water valve.
