Before we use Roots blower, check whether each component meets the requirements and whether the anchor bolts are fastened. Listen carefully to the bad sound of Roots blower. Check whether the rotation direction of the motor conforms to the direction indicated by the turning sign, or the roots blower cannot exhaust normally, which may cause blade collision and other accidents. When the roots blower is to be stopped, open the air valve slowly and close the outlet valve to turn off the power so that the roots blower can be completely closed.
Many people like to use a three blade roots blower. The important thing is that they are very convenient to use. More importantly, they are very stable when used, but they are unavoidable when used. The main reason for various damages is that they are limited by the use speed, so no matter how the speed changes, the wind pressure can remain constant. We are the solution. The pressure changes with the system resistance and is adaptive. The hard exhaust characteristic of forced gas transmission, that is, when the pressure changes, the flow changes very little.
Do not exceed the rated pressure value of Roots blower, which can be measured by the assembled pressure gauge. The content of particles in the air delivered by Roots blower shall be as small as possible, and the maximum size of particles inhaled shall not exceed the minimum clearance of the cylinder. Under the rated load of Roots blower, the bearing temperature after stable operation shall not exceed 55 ℃, and the maximum surface temperature shall not exceed 95 ℃.
In addition, the gear lubricating oil temperature of Roots blower generally does not exceed 65 ℃. The correct oil level for each oil filling should be in the middle of the gear mailbox indicator hole, and it should not be too full to avoid bringing lubricating oil into the cylinder and causing pool water pollution. It is also necessary to regularly change the lubricating oil for Roots blower. Generally speaking, the oil needs to be changed for the first time after 200 hours of operation at the first start. After that, the lubricating oil should be changed every 6 months. Before injecting new oil, the oil tank and gears should be cleaned with gasoline or neutral kerosene, and then refueled after being drained.
Service conditions of Roots blower:
1. The working environment temperature of Roots blower shall not exceed 40 ℃. If it exceeds 40 ℃, cooling measures shall be taken, otherwise the service life of the blower will be shortened. When the fan is configured outdoors, please set up a rain proof shed.
2. The foundation design shall comply with the relevant provisions of the national machinery and equipment installation project. The foundation shall be built on hard soil, which should be 100-250 mm higher than the ground and 800-1500 mm deep. The bearing surface of the foundation shall be 100-250 mm wider than the base, and its foundation shall not be firmly connected with other buildings and wall foundations. Sufficient space shall be reserved around the fan to meet the needs of maintenance and disassembly.
3. Remove welding slag and other foreign matters in the pipeline before installation. The valve shall be in the fully open state, otherwise the roots blower will be overloaded and the fan will be damaged.
4. Check and add main gear oil. When leaving the factory, the oil tank has been filled with gear oil. Please check and fill the main gear oil. In the shutdown state, fill it to the center of the oil window, do not add more, or it will lead to oil leakage.
5. Check the tightness of narrow V-belt and the deviation of pulley. Belt pulley deviation can be adjusted with a ruler. After being used for a period of time, the belt will become loose, and it needs to be readjusted.
6. Check whether the power supply voltage and frequency meet the requirements of the motor label.
7. Check the pulley rotation. When looking at the belt pulley, the rotation direction of the belt pulley should be consistent with the rotation sign arrow.
8. Before starting, manually rotate the pulley more than a circle, and check that the vent valve is fully open. If there is no abnormality, start the roots blower.
I believe that after reading the above contents, you should also understand the use method and conditions of Roots blower. I hope it will be helpful to you.
