How to maintain the three leaf roots blower:
The lubricating oil of the three blade roots blower shall be replaced once every 3-6 months or filtered with a copper wire mesh with a hole diameter of less than 50 microns. The oil shall be changed after 200 hours of operation. The muffler should also be overhauled once every six months or so, and some or all of the sound absorbing materials should be replaced. The air filter shall be maintained frequently, and the inlet and outlet valves and bypass pipes shall be kept in good condition.
In terms of external environment, attention should be paid to the following aspects: during outdoor configuration, rainproof sheds should be set up.
Roots blower shall be able to be used for a long time under the ambient temperature of no more than 40 ℃. When the temperature exceeds 40 ℃, exhaust fan and other cooling measures shall be installed to improve the service life of the blower.
Precautions for Roots blower maintenance:
Roots blower is the core mechanical part assembled on various equipment. Proper maintenance can not only prolong the service life, but also improve the work efficiency and save a lot of costs. The following details the maintenance procedures of Roots blower.
1. Before maintenance, disconnect the main power supply of Roots blower, and hang up the signboard.
2. Manually rotate the fan blade, observe the rotation, and adjust the belt tightness or coupling clearance and alignment.
3. Check the gaskets and packing seals on each joint face and replace them if necessary.
4. Clean the outer surface of the fan blade, housing and motor. In case of more oil stains on the fan blade surface, soak and scrub it with detergent.
5. Add lubricating oil (grease) to all rotating parts, and adjust the transmission mechanism of air valve to make it flexible and reliable.
6. Check the insulation resistance of the motor winding, fasten the wiring terminal of the power line, and check whether the motor is well grounded.
7. Check whether all electrical appliances in the Roots blower control cabinet are in good condition, and fasten all wiring terminals.
8. Check whether the transmission mechanism of the air valve is flexible and reliable, whether the wires are damaged, and whether the wire connectors are fastened well.
9. Turn on the main power supply of Roots blower and check whether the power indication is normal.
10. Adjust the belt pulley and belt.
11. Start up and test run for half an hour, observe that the indicator light of each instrument should be normal, and there should be no abnormal sound during operation.
The operation and service life of Roots blower depend on correct and frequent maintenance, and attention should be paid to the occurrence of any fault.
In addition to paying attention to general maintenance procedures, the following points should also be paid attention to:
(1) Check the fastening of each part and whether the locating pin is loose.
(2) Whether there is water leakage and oil leakage inside the blower body.
(3) There shall be no scaling, rust and scaling inside the blower body.
(4) Pay attention to whether the cooling condition of the lubricating oil is normal, pay attention to the quality of the lubricating oil, often listen to the blower for noise, and pay attention to whether the unit works under the condition that does not meet the requirements.
(5) Sometimes the overload of the blower is not displayed immediately, so pay attention to the increasing trend of the inlet and exhaust pressure, bearing temperature and motor current to judge whether the machine operates normally.
(6) Before disassembling the machine, each fitting dimension of the machine shall be measured, recorded, and marked on other parts to ensure the assembly and maintain the original matching requirements.
(7) For new machines or overhauled blowers, the oil tank should be cleaned and put into operation according to the operating procedures. It is recommended to replace all lubricating oil after 8 hours of operation.
(8) The maintenance and overhaul shall formulate a reasonable maintenance system according to the specific use conditions, and shall be carried out on schedule and recorded. Under normal conditions, the unit is required to replace the lubricating oil after 1000 hours of operation, conduct minor repair or inspection once after 4000 hours, and conduct major repair once a year and replace relevant vulnerable parts.
(9) Faults and troubleshooting; because Roots blower It is difficult to explain the causes and troubleshooting methods of the faults and causes related to the use conditions, operation conditions and other factors in simple words, which should be analyzed and eliminated according to the actual situation.
