Roots blower for power plant gasification
? Product details:
The power plant gasification Roots blower is a kind of Roots blower, which is mainly used in the power plant pneumatic conveying system, also called airflow conveying. It is a technology integrated system that uses the energy of airflow to transport bulk solid materials in closed pipes. It is a specific application of fluidization technology.
The pneumatic conveying device of the gasification roots blower is simple in structure and easy to operate. It can be used for horizontal, vertical or inclined conveying. In the conveying process, physical operations such as heating, cooling, drying and air flow classification of materials or some chemical operations can also be carried out at the same time.

? Application of gasification roots blower ：
The power plant gasification roots blower is also called the power plant gasification roots blower, the power plant gasification roots blower, and the ash silo gasification blower, which are mainly used in the power plant pneumatic conveying system, also known as air flow conveying. The technology integration system uses the energy of air flow to transport bulk solid materials in closed pipes. It is a specific application of fluidization technology.

? Features of gasification Roots blower ：
1. The product is flexible in installation, and can be installed vertically or horizontally.
2. The oil tank is separated from the air chamber, and the product air chamber is free of oil, so that the air delivered is clean and free of oil.
3. The intake and exhaust ports are diamond shaped, which can reduce air flow pulse and noise.
4. The impeller profile is designed as a cycloidal structure, which changes the seal between the casing and the rotor into a zero seal, which can greatly reduce the internal leakage, thus providing the volume efficiency of the blower to achieve the purpose of energy saving.
5. The synchronous gear is made of high-quality alloy steel by fine grinding, and the accuracy grade reaches Grade 5 of GB10095.
6. The dynamic balance accuracy of the rotor reaches G2.5. Thus, the blower can run stably, with small vibration, no mechanical noise and long service life.
7. The fan is simple in structure, high in machining precision and convenient in use and maintenance.
? Service conditions of gasification roots blower ：
1. The inlet air temperature shall not exceed 35 ° C.
2. The content of solid particles in the gas shall not exceed 100m3, and the maximum particle size shall not be greater than the specified minimum working reaction.
3. The coal tar index of gas must meet the requirements of TJ28-78 in the design of urban gas specification.
4. The bearing temperature shall not exceed 85 ° C.
5. The maximum temperature of lubricating oil shall not exceed 65 ° C.
6. The pressure indicated on the pressure gauge of the fan shall not exceed the pressure rise range specified in the manual, otherwise it must be stopped, and check whether the air inlet is blocked in the system, whether the air inlet valve and exhaust valve are blocked and closed. If the static moving parts on the fan are rubbed, wait for other problems and take appropriate measures.
