Concrete mixing station electrical control system failures and measures 1, PLC can not communicate due to communication line or communication network connector poor contact or communication failures or damage caused by the expansion module, you can do this for communication lines and communication connectors and communication expansion module to check and replace. 2, DRO garbled or power phase distortion caused by the DRO DRO can then be replaced gradually investigation; external power phase as the contactor or circuit breaker contacts burned, not setting a good breaker current or contact contacts burn caused by phase; Remedy: Check the power supply can be updated, if found to replace the circuit breaker tripped normality contactor or a road segment, the current setting. 3, sand or stone, sand or stone weighing scales door malfunction door is not closed alarm: Due to the scale diagram sand or stone door is not closed to display small concrete mixing plant, concrete mixing scales door flashing alarm stations, scales actually closed the door, scales door trip switch mounting position or cylinder stroke has changed; to this end can be adjusted scales door limit switch position or in parallel with a limit switch. Sand or stone gap value is too large or too large measurement error: the doors are open limit screw is not adjusted well, adjust the doors open the door stopper bolt, additives or water drop or error is too large, additives or water fine, said range of values ??not adjusted well. 4, data loss automatic operation manual intervention, common parameters not set correctly, you can run automatically each Scales full after manual intervention, common parameters set feeding time must be greater than "1S", the production process is stopped automatically when all scales has said that full, but do not feed batching machine part 90 concrete mixing stations, intermediate positions have expected, the middle doors off the lower limit value is set too small; you can increase the value off the middle of the lower doors. Stir station Environment: Environmental protection is to protect and improve the mixing station environment, prevent pollution and other public hazards, safeguarding human health. We have to take effective measures to prevent mixing station construction process wastewater generated waste, dust, noise pollution and harm to the environment. For the production of dust generated in the process should be properly handled, concrete mixing station equipment should be designed to cement concrete mixing station pool filtration equipment, mixing equipment to take appropriate measures to deal with dust. 1. Noise control: not a lot of noise at night arrange mechanical construction, to avoid all non-construction noise. 2. Dust Action: Install four sprinklers in the mixing area upstairs material side, to prevent dust scattering. Field area sprinkler control dust. 3. Waste treatment: the construction and life in the production of concentrated waste stacking and timely manner. 4. Sewage: Sewage and waste water generated in construction and life after the sedimentation tank before discharge. 5. fire prevention measures: Strengthening the construction site fire safety awareness education, on-site with a sufficient number of fire-fighting equipment, to prevent fires. 6. cover transportation construction materials used to prevent leakage spill, pollution along the highway facilities.
