Roots blower in the use of the process there are some details that we need to pay attention to, about these details Roots blower editor to take you to understand.
I. Installation:
The foundation should be firm, with a flat surface, and the foundation should be above ground level. The surrounding space should be enough for dismantling and overhauling. If the temperature in the fan room exceeds 50℃, it will shorten the service life of the Roots fan, so it is necessary to set up ventilation fans or other devices so that the temperature in the fan room does not exceed 40℃.
II. Pipes:
Fan ducts should be flexibly connected, do not put debris on them. Ducting material can withstand the temperature and wind pressure during exhaust (steel pipe may be used). The inside of the piping is clean to prevent debris from entering. Install a check valve to prevent backflow due to reversal from entering the fan.
Third, please pay attention before operation and operation:
1. Check the tightness of bolts and nuts.
2. Clear the pipe of foreign matter.
3. Open the valve completely.
4. Check the gear oil. No gear oil is added to the gear box at the factory. When adding gear oil, add it until the center of the oil mark; adding too much oil will result in oil leakage.
5. Bearing oiling. There are two grease nipples on the pulley side that you can add oil to with a grease gun.
6. Check the rising force of the narrow V-belt and the deflection of the pulley. The pulley can be corrected by metal ruler or rope, and adjust the tightness, such as the use of a rise meter can be more convenient to adjust the belt rise, and, after 2-3 days of operation, because the belt and pulley grinding, the belt will become slack, please re-adjustment.
7. Check the voltage and frequency of the power supply.
8. Check the cable connections. The direction of rotation of the main shaft is counterclockwise when viewed from the pulley side.
9. Before starting the machine, the pulley must be coiled by hand, and the fan can be started by electricity only when there is no abnormality in the rotation search.
IV. Operational instructions
1. At the beginning of operation, there is noise and high current due to the stickiness of the lubricant, which can disappear in 10-20 minutes.
2. Adjustment of gas flow. The flow rate cannot be adjusted by the valve, but can be adjusted by changing the slewing speed or increasing the counterflow pipe.
3. The fan should operate within the specified pressure range.
The pressure gauge switch is normally closed and can be opened if pressure measurement is required.
V. Maintenance and overhaul
Maintenance and overhaul should be carried out regularly during production, and the table may be modified appropriately according to the actual situation.
