In order to maintain the normal operation of the central dust collecting system, after the practice and exploration of the production site, the author thinks that the following operations should be done. In terms of operation management, the following operations should be carried out in each shift to empty the water in the filter tank and avoid the blockage caused by paste bag. Dust collector cloth bag talked about because the air is pressurized by the air pressure pump, during which part of the water vapor will condense into water due to high pressure. If it is not cleaned in time, the wet air will be blown into the cloth bag, which is bound to paste the bag to form obstruction. Often check the operation status of the solenoid valve in operation, there are two kinds of common faults, can not be reset after the conduction of the injection, the formation of a regular vent, so that the air pump pressure is not up, can not form with the injection effect of pressure. Reason: The plane adsorption force between the electromagnet and the movable armature (located outside the electromagnet) is greater than the force of the valve plate (after the electromagnet stops the power supply and loses suction) to push the connecting rod to reset it. Method: Between the electromagnet and armature cushion a round non-absorbent oily tissue, reduce the adsorption force, so that it can be normal reset, rubber barrier damage, high pressure air can not blow into the cloth bag. This kind of fault, during the driving period, people in the vicinity of the pulse dust collector for general inspection, it is difficult to find. Because, the electromagnetic valve is still operating after the estrangement is damaged, the operator can still hear the normal distance of the blowing sound. But the high pressure air did not blow into the bag, a false operation.
Debugging and operation of central dust collecting system:
1. Abnormal temperature, pressure, moisture and other problems often occur during the beginning of the parts operation, which will cause damage to the new central dust collecting system device.
2, the installation of dust filter bag, after use, whether there are bags, loose mouth, wear and other situations.
3. After being put into operation, the discharge of the chimney can be determined by visual inspection. Pay attention to whether there is condensation in the bag room and whether the ash removal system is. Prevent plugging and erosion, ash accumulation will affect the production of central dust collecting system. The adjustment of cleaning cycle and cleaning time is an important factor affecting the performance and operation of the central dust collecting system.
4. Whether the treatment air volume and the pressure and temperature of each test point are consistent with the design. Fan rotation direction speed bearing vibration and temperature. The normal operation of the central dust collecting system directly affects whether it can be used on the pipeline. Otherwise, the central dust collecting system is likely to lose its effectiveness soon.
5. Debugging the run-in period of the central dust collecting system should be careful and careful. The rapid change of the gas temperature of the dust removal accessories will cause the deformation of the fan shaft, resulting in an unbalanced state and vibration in operation. Once the operation is stopped, the temperature will drop and the vibration will occur when the operation is restarted. If the central dust collecting system cleaning time is too long, it will cause filter bag leakage and damage.
