Emulsion pumper "finger dictation" standard <br /> I. Job description Leaders are welcome to come to work face inspection and guidance, I am the *** team on-duty emulsification pump driver ***, my job responsibility is to operate and Maintain the emulsification pump. The emulsification pump is operating normally on the shift, please give instructions.
Basic situation of the working face: This working face is a *** fully mechanized mining face with a strike length of *** m and a cut length of *** m. The mining coal seam is *** coal seam, and the average coal seam thickness is *** m. A total of *** brackets are installed.
Equipment performance: The type of emulsion pump operated is ***, the motor power is *** kW, the flow rate of a single pump is *** L / min, the liquid supply pressure is *** MPa, and the pump station is arranged in two pumps One box is mainly used to supply liquid to the hydraulic support and single pillar on the working surface.

Check before starting pump Roadway top, globe valve, hydraulic pipeline, crankcase, gearbox, unloading valve, emulsion, pressure gauge, equipment operation button, pump box Roadway top, globe valve, hydraulic pipeline, crankcase, gearbox, unloading valve, emulsion, pressure gauge, equipment operation button, pump box The inspection: 1. The roof of the pumping station and the nearby roadway is complete and the support is in good condition; 2. The shut-off valve handle is flexible and reliable; 3. The hydraulic pipeline is connected reliably without leakage and the pipeline is neatly hung; 4. The crank case and gear The oil level of the tank meets the requirements, and there is no loosening of the screws; 5. There is no foreign matter in the pump box, and the concentration of the emulsion meets the requirements; 6. The equipment operation buttons are sensitive and reliable; show normaly. Confirmation is complete.
Start of the emulsification pump Start button, venting plug, liquid supply valve, motor, emulsion pump, pipeline, pressure gauge, pump box Start button, venting plug, liquid supply valve, motor, emulsion pump, pipeline, pressure gauge, pump box 1. After receiving the pump-on signal, jog the motor to confirm that the motor rotation is in accordance with the direction of the arrow on the pump body; 2. Open the venting plug and tighten the plug after the venting is completed; 3. Press the start button to start the motor , The pressure is expressed to the specified value; 4, open the liquid supply valve to supply liquid to the work surface; 5, after the start of the motor and pump temperature is normal, stable operation, normal sound; 6, the pipeline is not leaking, the pressure gauge indicates normal. Confirmation is complete.
In operation Pressure gauge, oil gauge, pipeline, emulsion concentration, equipment operating parts Pressure gauge, oil gauge, pipeline, emulsion concentration, equipment operating parts The pressure gauge indicates normal, the emulsion concentration meets the requirements of the ratio, the liquid level is appropriate, there is no leakage, the temperature of each operating part is normal, and there is no abnormal sound and vibration. Confirmation is complete.
Stop the pump Stop button, liquid supply valve Stop button, liquid supply valve 1. Stop the emulsification pump when the working surface does not require liquid supply. Press the stop button to shut off the power switch. 2. Close the liquid supply valve to remove debris around the pump station. Confirmation is complete.
Precautions Safety valve, pipeline, unloading valve, emulsion Safety valve, pipeline, unloading valve, emulsion 1. Under normal circumstances, the pump must not be stopped without permission from the working person. When stopping the pump, you must contact the working person to stop the pump after permission. 2. It is strictly forbidden to replace the hydraulic components under pressure during maintenance. 3. The pump should be stopped immediately: there are abnormal noises and odors; the temperature exceeds the stipulation; the pressure gauge indicates abnormality; the automatic proportioning device is abnormal; the control valve fails or is out of control; the filter is damaged or blocked; the liquid supply pipeline is broken and disconnected. Liquid; 4, when the liquid level is low, timely rehydration, every 2h with a concentration meter to determine the concentration.
Third, the operation of the pump head tank detailed inspection, whether it is intact and of good quality; in the dynamic inspection of the pumping station, abnormalities to check the cause;
Check the concentration within 2 hours. The concentration is between 3% and 5%. Moderate concentration is received. The equipment and tools check carefully after receiving orders and shutdown.
Equipment maintenance must be meticulous, power failures and lockouts must be recorded; pipeline leaks must be corrected in a timely manner, and maintenance under pressure is not feasible.
