The inspection and maintenance of roots blower

The inspection and maintenance of the roots blower - 2020 02 - 08 jiaozuo strong roots blower Wang Zhanguang cement in the cement industry is multi-purpose and conveying of powder material such as coal, also often applied to the powder material homogenizing and helps the flow discharge, burner except for transport to a net wind also provide, etc. So it is a key role to be reckoned with. Roots blower here's inspection maintenance and simple fault exclusion. A roots blower, roots blower inspection maintenance inspection and maintenance according to its composition can be divided into the following several aspects. 1. First listen to the equipment operation is normal voice, between the impeller and the impeller to have sound, whether there is friction between housing and impeller. Sound gear mesh is uniform, A beating slapping sound transmission belt is too loose. Listen to the bearing whether sound even. 2. Second to check the equipment vibration, check whether the equipment vibration is increased, mainly bearings, transmission, whether other aspects such as pipeline vibration. 3. Check the loose, and see if there's any loose for the anchor bolts and other fasteners. 4. To temperature check, mainly bearing, shell, motor, etc. 5. Check the lubrication, and see if the gearbox oil level is normal. 6. To examine the volatile content, see if drive shield interference, clearing the incompatible with the instability of the equipment operation objects surrounding equipment. 7. Other aspects of the inspection, see if there is congestion in air inlet, the relief valve is reliable, each valve is reliable, the abnormal phenomenon such as stents for cracks. 8. Check current motor and fan flow pressure is normal. Two, simple failure analysis and roots blower ruled out running also can appear a little fault, must be timely discovery and eliminate, according to experience, usually there are several aspects. 1. Small air volume, high current when the inlet filter dirt such as foreign body, will affect into the wind, causing the motor current increases, volume decreases, shall replace or clean the filter at this time. 2. Small volume, low current at this time should check whether frequency converter speed control function of the failure, do not tally with the actual whether display frequency. Also check whether the drive belt is too loose skid. 3. Large current, high pressure when gas pipeline jam or valve malfunction, the wind is bad. Should check whether the pipe is at this time there are obstacles blocking, check whether the valve plate, and timely maintenance, cleaning, troubleshooting. If the pressure overruns, setting of the relief valve should be deflated pressure limit. 4. Belt skid or belt off powder belt slippage on the one hand, shorten the life of the belt, would also reduce the fan speed, when the inspection found that such a problem, should be timely taut; If found at the end of the belt off, usually is caused by the belt does not accord with grooved, should adjust the size of the pulley in the same plane, if it's new for belt may be model is wrong, it should be replaced in a timely manner. 5. Roots blower abnormal noise if abnormal sound, should be a rotor collision friction, bearing damage, gear mesh is out of question, can press of roots blower in the maintenance of several key methods to solve maintenance. 6. The vibration of the vibration of the roots blower rule out may come from the anchor and fasteners loose, check the fastening. If from the bearing vibration, rotor, gear can consult roots blower in the maintenance of a few key '. 7. Bearing, gear box, high temperature appear such problems are caused by poor lubrication, should be replaced timely supplement of lubricating oil. Other causes of fever can also refer to repair solution. At the same time to health to clean equipment, strengthening ventilation, to create conditions for equipment heat dissipation. Conclusion: the content of the roots blower for daily inspection maintenance and failure of the simple analysis and ruled out, if there is wrong please correct me criticism. （ Source: wisdom cement)
