Diesel engine fire pump maintenance


The maintenance of diesel fire pump

The maintenance of the diesel fire pump should strictly implement the maintenance system, so that the diesel fire pump always maintains a good technical state and a clean appearance, and is always ready to adapt to a fast and effective response. In an emergency, and put out the fire in a timely manner.
The diesel engine fire pump should be maintained every day.

Daily maintenance

1. Keep the machine room tidy. The diesel machine fire pump and its supporting outfit should be flexible and dependable.
2. Check whether the connections of the diesel machine fire pump are good, whether the rotating corridor are flexible, whether the oil painting circuits, and measures are connected reliably, whether the wiring is loose, and whether the froth mixing system and cooling system are complete and normal;
3. Check whether the capacity of energy tank, oil painting visage, heat exchanger, water companion tank and froth liquid is sufficient, and add it in time if inadequate;
4. Check whether the machine oil painting circuit is normal and dependable to insure that it can be put into operation at any time;
5. The machine must be started daily to check its starting performance. Pumping must be done several times a week after footling.

First- class maintenance

Every three months or accumulated 100 hours of operation, position 1 conservation must be performed with lubrication and tensing as the center.
1. Clean the surface of each element of the unit;
2. Check the oil painting position of the machine crankcase, check whether the crankcase ventilation pipe is good, and whether the device is firm;
3. Check the quantum of oil painting in the pump grease mug and add it if necessary;
4. Check and acclimate the miserliness of the belt.
5. Check the face of machine oil painting, water pump, and clean air draw;
6. Check the miserliness of the machine, water pump, transmission and pipeline;
7. Clean the outside of the battery, add distilled water and sufficient power;
8. Clean the air sludge;
9. slick each lubrication point as demanded.

Two-class maintenance

After running every 6 months or 500 hours, secondary conservation must be carried out grounded on examination and adaptation. The particulars are as follows
1. First position conservation of all particulars;
2. Clean the oil painting sludge and replace the sludge element;
3. Check the machine lubrication system and replace with new oil painting;
4. Clean energy tank, oil painting pump sludge and channel;
5. Replace paper energy sludge;
6. Clean oil painting visage and oil painting pumping unit;
7. Check and acclimate stopcock concurrence and injection pump advance angle;
8. Disassemble and check the injection pump and energy pump as needed, check the injection pressure and injection condition of the high- speed injector;
9. Check the battery position and electrolyte attention, remove the air holes on the battery cover, and charge if necessary;
10. check electrical outfit, clean and slick starter and machine comportments
11. Check the miserliness of the pump. The bay and outlet of the pump are closed, and the vacuum pump is used to test the vacuum. When the vacuum dialing reading rung0.79 mpa, the vacuum drop shouldn't be lesser than0.03 mpa/ min during the arrestmenttest.However, check and exclude the cause of the leak in time; If the vacuum drips too fast.
12. slick each lubrication point as needed.

Three- class maintenance

The pump set generally runs for 1000- 1500 hours, or it's set up that the machine power is significantly reduced, the diesel consumption is increased, the exhaust bank or blue bank is perished as a whole, and the three- position conservation should be carried out
1. All major conservation and secondary conservation particulars.
2. Disassemble and check machine assembly
1) Clean up the carbon deposits in the combustion chamber, exhaust pipe and muffler;
) Measure the quantum of wear and tear in the cylinder and change the piston ring and cylinder liner if necessary;
3) Check the concurrence between the connecting rod bearing and the crankshaft main bearing, replace the bearing if necessary, check the axial concurrence of the camshaft and crankshaft, and acclimate if necessary;
) Check the miserliness of the stopcock seat and grind if necessary.
5) Clean the cylinder block, oil painting visage and oil painting strainer;
) Clean the dirt on the heat exchanger and machine water tank, and check the function of the thermostat.
7) Remove the pump, clean and change the oil painting; remove the froth kindler and remove the dirt;
) Perform a pressure test of1.5 times the rated outlet pressure of the channel affair system, and replace oohing pipes and faucets timely;
) If necessary, paint again;
) slick each lubrication point as needed.
