　　Three-leaf Roots blowerIt is a volumetric blower with impeller end face and front and rear end cover. The principle is a rotary compressor, which uses the relative movement of two vane rotors in the cylinder to compress and transport gas. This blower is simple in structure and convenient to manufacture. The three-leaf Roots blower is widely used in aquaculture aeration, sewage treatment aeration and cement transportation. It is more suitable for gas transportation and pressurization systems in low-pressure occasions. It can also be used as a vacuum pump.

The three-leaf Roots blower is a high-speed machine, so it will produce vibration, and due to the pulsation of its internal air, it also increases the vibration of the Roots blower, so it needs to be fixed on the ground during installation. According to different fan models, dig a square pit 300mm deep and 150*150mm square on the ground according to the size of the fan, and embed anchor bolts. Then, the three-leaf Roots blower is connected by bolts and nuts, and then the square pit is filled with cement concrete. After the concrete is fixed, tighten the nut firmly to connect the fan base and the concrete firmly, which can reduce the vibration displacement of the three-leaf Roots blower during operation and improve the safety of equipment operation. And because the vibration is reduced, the service life of the fan is also greatly extended.

　　Three-leaf Roots blowerThe safe operation and service life depend on regular and correct maintenance, and any signs of accident should be paid attention. If you do not use the three-leaf Roots blower for a long time, you need to cut off all the power on its body and place it in a ventilated and dry place, which can effectively avoid rust caused by long-term non-use. In addition, the Roots blower should be regularly refueled during use. Only in this way can the flexibility of the three-leaf Roots blower be guaranteed to the greatest extent.

Apart from that,Three-leaf Roots blowerUsually also pay attention to the following points:

1. Check the fastening of each part of the Roots blower and whether the positioning pin is loose. If it is loose, it must be fixed firmly.

2. There shall be no scaling, rust and peeling inside the fan body. Prevent oil leakage inside the body.

3. When disassembling the machine, measure the matching dimensions of the machine, make records, and make marks and directions on the parts to ensure assembly and maintain the original matching requirements.

4. Sometimes the overload of the Roots blower is not immediately displayed. Pay attention to the changes in the intake and exhaust pressure, bearing temperature, and motor current to determine whether the machine is running normally.

Under normal circumstances, the lubricating oil must be replaced after 1000 hours of operation. 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 operation of the Roots blower for noise, and pay attention to whether the unit is working under non-conforming working conditions.

6. The new or overhauled Roots blower should be put into operation according to the operation steps. It is recommended to replace all lubricants after 8 hours of operation. Routine maintenance is very important, minor faults must be repaired before they can be put into use.
