When we made a purchaseRoots blowerAfterwards, regular maintenance should be carried out, preferably with scheduled shutdowns for maintenance, which will greatly extend the service life of the fan. The vulnerable parts of the Roots blower should be replaced in a timely manner to avoid losses caused by sudden shutdown of the fan in the later stage. From the fault to the solution, and then to the daily maintenance text, the 19th National Congress of the Communist Party of China lists 19 points. It is difficult for our equipment to break down if we do these things well.

1： 1. Pressure rise caused by pipeline blockage 2. Vibration caused by improper installation of belt cover 3. Wear of fan bearings 4. Grinding damage caused by dust entering the fan 5. No lubricant 6. Loose V-belt pulley 7. Sliding of V-belt

2： 1. Reinstall or replace the pipeline. 2. Reinstall the belt cover. 3. Replace the new bearing. 4. Disassemble and inspect the fan. 5. Add lubricating oil. 6. Tighten the thread. 7. Adjust the belt tension. Impeller and impeller friction

3： 1. There are pollutants and impurities on the impeller, causing small clearance. 2. Gear wear, causing large side clearance. 3. Poor fixing of gears, unable to maintain impeller synchronization. 4. Bearing wear, resulting in increased clearance

4： 1. Remove dirt and check for any damage to the internal components. 2. Adjust the gear clearance. If the gear backlash is greater than the average value by 30% to 50%, the gear should be replaced. 3. Reinstall the gear and maintain a taper fit with a contact area of 75%. Replace the friction between the bearing impeller and the wall panel casing.

5： 1. Incorrect installation clearance; 2. The operating pressure is too high, exceeding the specified value; 3. The operating temperature is too high; 4. The casing or machine base is deformed, and the positioning of the fan is ineffective; 5. Poor axial positioning of the bearing.

6： 1. Adjust the gap again; 2. Identify the cause of overload and reduce the pressure to the specified value; 3. Check installation accuracy and reduce pipeline tension; 4. Check and repair the bearings, and ensure clearance. Temperature too high

7： 1. There is too much, too thick, and dirty oil in the fuel tank; 2. Filter or muffler blockage; 3. The pressure is higher than the specified value; Excessive wear and large clearance of impeller 4; 5. Poor ventilation and high indoor temperature result in high inlet temperature. 6. Operating speed is too low, causing belt slippage.

8： 1. Reduce the oil level or carry oil; 2. Remove blockages; 3. Reduce the pressure difference through the blower; 4. Repair gaps; 5. Open ventilation openings to lower room temperature; Increase the speed to prevent the belt from slipping. insufficient traffic

9： 1. Import filter blockage; 2. The impeller is worn and the clearance has increased too much; 3. Belt slippage; 4. High import pressure loss; 5 pipes causing ventilation leakage.

10： 1. Remove dust and blockages from the filter; 2. Repair gaps; Tighten the belt and increase the number of belts; Adjust the import pressure to reach the specified value; 5. Check and repair pipeline belt damage

11： 1. Overloaded operation 2. Belt slippage 3. Two pulleys not parallel 1. Adjust 2. Adjust 3. Adjust for oil leakage or oil leakage into the casing

12： 1. The fuel tank is at a high level and leaks out through the oil outlet; 2. Seal wear, causing oil leakage at the shaft end; 3. The pressure is higher than the specified value; The ventilation openings of the wall panel and fuel tank are blocked, causing oil leakage into the casing.

13： 1. Reduce the oil level; 2. Replace the seal; 3. Clear the ventilation opening, install a 2mm hole plug in the middle chamber, and open the plug under the wall panel. Stop immediately due to abnormal vibration and noise 

14： 1. The clearance of the rolling bearing exceeds the specified value or the bearing seat is worn; The side clearance of the gear is too large, misaligned, and not securely fixed; Due to foreign objects and dust, impellers collide with each other and with the casing; 4. Impeller collision caused by overload and shaft deformation; Due to overheating, there is friction between the impeller and the inlet of the casing; Due to fouling or foreign objects, the impeller loses balance; 7. Loose anchor bolts and other fasteners. 

15： 1. Replace the bearing or bearing seat; Reinstall the gears and ensure the side clearance; 3. Clean the blower and check if the casing is damaged; 4. Check the back pressure, check if the impeller is aligned, and adjust the clearance; 5. Check the filter and back pressure, and increase the gap between the impeller and the inlet of the casing; Clean the impeller and casing to ensure the working clearance of the impeller; Tighten the anchor bolts and level the base. Motor overload 

16： 1. Compared with the specified pressure, the pressure difference is large, that is, the back pressure or inlet pressure is high; Compared to the required flow rate of the equipment, the fan flow rate is too high, resulting in an increase in pressure; 3. Inlet filtration blockage, outlet pipeline obstruction or blockage; 4. Collision and friction (jamming) of rotating parts; 5. The oil level is too high; 6 narrow V-belt overheating, excessive vibration, and small pulley.

17： 1. Reduce the pressure to the specified value; 2. Release excess gas into the atmosphere or reduce the speed of the blower; 3. Clear obstacles; Immediately stop the machine and investigate the cause; Adjust the oil level to the correct position; Check the belt tension and replace it with a large-diameter pulley. Motor stops running

18： 1. Overload 2. Damage to fan 3. Poor power supply wiring 4. Dirty or damaged bearings inside the motor 5. Quality issues with the motor itself

19： 1. Check the pipeline system 2. Maintenance 3. Repair 4. Clean the fan or replace the bearing 5. Replace the motor
