We all know that no matter what kind of equipment, if we can do daily maintenance after using it, it will greatly increase its service life, the same is true for mortar spraying machine. Specifically, what details should be paid attention to when doing routine maintenance of mortar spraying machine?
(1) Inspection and maintenance before operation the mortar spraying machine
1. Mortar spraying machine: including the motor, power supply and transmission lines, electrical control box inspection, each switch should be in the specified state.
2. Lubricating oil: The number of times the hand pump is forcibly refueling.
3. Cross the hopper with or without debris and slag.
4. Inspection of spray hose, nozzle and air duct.
5. Equipment air transport inspection.
1 point motor to check the direction of rotation (main motor clockwise, air compressor counterclockwise)
2 air compressor, wind pressure, air volume, snapping adjustment
3 Checking the meter is only the case, especially whether the voltage is required for boulevard design, crossover transmission line, wire diameter distance and joint connection.
6. The setting of wind pressure and combined air flow is caused by the wind pressure switch not being loosened during transportation, and the pressure spring should be re-adjusted.
(2) Inspection and maintenance in shotcreting operations
1. Electrical equipment check each instrument, button, air pressure switch, ball gates, motor temperature is normal
2. Spray hose, nozzle and air duct, all have sealing and fixing conditions. There shall be no signs of knotting or breakage in the duct and spray pipe.
3. Wind system: check joint seal, fixing and wind pressure, air volume and working conditions.
(3) All bolts, nuts and screws should be checked frequently for looseness and found to be loose for dozens of tightening (especially for the bolts of the electric control box)
(4) Maintenance after the mortar spraying machine operation
1. Grouting hose, air duct, nozzle cleaning inspection
2. Mortar spraying machine cleaning and inspection
3. Air compressor. Turn off the power supply, air supply, and close each valve to check each part.
4. The electrical part cuts off the power and checks each part.
5. Remove the booster nail and rotor, reassemble after cleaning.
6. Other problems encountered during operation, cleaning, maintenance, etc.
