What are the phenomena and maintenance methods of Roots blower failure
Roots blower In the daily use process, it is necessary to carry out regular overhaul and maintenance, timely find the fan failure, and replace the vulnerable and consumable parts, so as to improve the service life of the equipment. However, some users still don't know how to carry out the maintenance work in use. Today, I put the Roots blower In case of failure, what phenomenon of wind turbine appears and the specific maintenance methods are introduced as follows:
1、 Abnormal noise
Roots blower In addition to the normal operation sound, if there are other abnormal sounds, the cause of the abnormal sound should be determined in time, focusing on whether the belt is slipping, whether the link parts are loose, whether there are foreign matters inhaled, whether the bearing and motor are faulty.
2、 Abnormal vibration
Focus on measurement Roots blower The vibration value was recorded. When the motor directly drives the impeller and other fans, the vibration data of the bearings installed at both ends of the fan shall be measured. For Roots blower driven by the drive group, the vibration data of the bearing installed on the bearing base shall be measured.
3、 Abnormal temperature
judge Roots blower If the temperature of the belt pulley is abnormal, if the temperature of the belt pulley is abnormal, whether the temperature of the belt pulley is abnormal Roots blower Belt tension.
In order to ensure the safe and trouble free operation of Roots blower equipment, we should regularly overhaul and maintain the fan equipment. The interval period is usually determined according to the type, working condition, use, reliability, importance and other indicators of Roots blower.
1、 Casing cleaning
Check and clean the casing, check whether there is air leakage, whether the surface welding has collapse, and clean the internal dust and oil accumulation.
2、 Inspection of spindle
Check whether the spindle is bent or deformed and the wear degree of the mating surface, and replace the spindle if necessary.
3、 Maintenance of impeller
Remove dust and dirt on impeller regularly. Especially when the fan is used to transport medium containing viscous substances (such as lampblack) or dust, the impeller parts should be cleaned at least once a month. Otherwise, the accumulated magazine will destroy the dynamic balance of the impeller, which will lead to the fan vibration aggravation and even damage to the parts. Check the wear, corrosion and deformation of the impeller, and replace the impeller if it is serious. Check whether the connection of impeller shaft head and hub is reliable, and correct if there is looseness. Check whether the clearance between impeller, air inlet and casing is even. After the maintenance of the fan, the balance of the impeller should be checked. If the dynamic balance is damaged, it should be adjusted again.
4、 Gear oil change
Roots blower The lubricating oil should be changed regularly. Generally, it should be changed every 3-6 months or filtered with copper wire with pore diameter less than 50 μ M. The lubricating oil should be replaced regularly, and the muffler should be overhauled every half a year or so, and part or all of the sound absorption materials should be replaced. The air filter should be maintained frequently. The inlet and outlet valves and bypass pipes should be kept in normal and good condition. Any problem should be repaired immediately.
Summary: Roots blower During normal operation, the temperature of fan bearing, lubricating oil in oil tank and motor shall be checked regularly to avoid the loss of equipment due to high temperature and high pressure. Roots blower The abnormal situation of the fan is usually manifested as abnormal sound, abnormal temperature and intensified vibration. Therefore, in the daily operation of the fan, special attention should be paid to the overhaul and maintenance of these items.
