Common Troubleshooting for Automatic Mortar Jetting Machine

Common Troubleshooting for Automatic Mortar Jetting Machine

The mixed materials in an automatic mortar jetting machine are fed into the hopper from the batching mixer via a vibrating screen. The materials are then injected into the rotor body's straight-through cavity by the shifter. As they flow towards the discharge port, compressed air from the air chamber blows the material into the discharge elbow. Here, another air stream from the cyclone accelerates and rotates the material, which then enters the feeding pipe, reaches the nozzle, and is sprayed out after adding supplementary water or a liquid accelerator.

During operation, various issues can arise with the automatic mortar jetting machine. Here are some common troubleshooting steps:

1. Sudden Automatic Shutdown:

   • Possible Causes:
     • Power Failure: If there's a sudden power outage, disconnect the power, and clean the delivery hose, pump core, and accessories. Cover the disassembly area to avoid mortar injection due to pressure release.
     • Motor Overload: Check if the fuse is blown.

2. Blockage or Malfunction Due to Dry Slurry:

   • Steps to Resolve:
     • Reverse Power: Turn the power to reverse.
     • Reduce Pressure: Run the machine in reverse for about 30 seconds to reduce pressure.
     • Clean Spray Gun: Check and clean the nozzle.
     • Check Material Flow: If material isn’t flowing, the hose may be blocked. If so, remove and clean the hose before reconnecting and restarting the automatic mortar jetting machine.

3. Slow or No Slurry Output Despite Normal Operation:

   • Possible Causes:
     • Worn Pump Core: If the pressure gauge shows little or no pressure, the pump core might be worn and needs replacement.
     • Dry Slurry in Hopper: Dry slurry or poorly flowing dry powder can cause the pump core to experience dry friction, leading to overheating and potential burnout in the automatic mortar jetting machine.

By following these troubleshooting steps, you can ensure the efficient operation of your automatic mortar jetting machine.
