Asphalt Mixing Plant 60 Ton Maintenance

When the asphalt mixing plant 60 ton is in use, the fuel pressure regulating valve or pressure reducing valve should be checked regularly to determine whether the surface of the lock nut on the adjustable bolt is clean and removable. If the surface of the screw or nut is too dirty or rusty, it needs to be repaired or replace regulator valve.
 

Regularly check the oil pump of 60 ton asphalt mixing plant to determine whether the sealing device is intact and whether the internal pressure is stable, and replace the damaged or leaking sealing device. When using hot oil, check that all oil lines are well insulated. The filter installed between the fuel tank and the fuel pump must be regularly cleaned and checked for excessive wear to ensure smooth flow of fuel from the fuel tank to the fuel pump and reduce the possibility of potential component failure.
 

The "Y" filter on the burner of the asphalt mixing plant should be cleaned frequently, especially when heavy oil or residual oil is used, to prevent the nozzle and valve from being clogged. When working, check the pressure gauge on the burner to see if it is within the normal range. For burners that require compressed air, check the pressure device to see if the required pressure is being generated in the burner, clean all filters on the supply line and check the line for leaks.
 

Check that the inlet guards on the combustion and atomizing air blowers are properly installed and that the fan housings are free of damage and leaks. Observe the operation of the blades, if there is too much noise or vibration, adjust the blades to eliminate them. For blowers driven by belt pulleys, lubricate the bearings regularly and tighten the belts to ensure that the blowers can generate rated pressure.
 

Clean and lubricate the joint of the air valve to see if the operation is smooth, and replace the parts if there is any obstacle in the operation. Determine whether the wind pressure meets the working requirements. If the wind pressure is too low, it will cause tempering, which will lead to overheating of the guide plate at the front end of the drum and the material shifting plate in the combustion zone. If the wind pressure is too high, the current will be too large, and the temperature of the bag will be too high or even scorched.
 

The fuel injection nozzle of the asphalt mixing plant 60 ton should be cleaned regularly, and the spark gap of the ignition electrode should be checked; the flame detector (electric eye) should be cleaned frequently to ensure whether the position is installed correctly and whether the temperature is suitable. Improper position and high temperature will cause photoelectric signal instability, even fire break.
