进口罗茨风机美国阿卡迪亚品牌

进口罗茨风机Principle:

Roots blower is a kind of positive displacement fan, with two two blade impellers rotating relatively in the space sealed by the casing and wallboard. Because each impeller adopts involute or epicycloid envelope, the two blades of each impeller are identical, and the two impellers are identical, which greatly reduces the processing difficulty. The impeller is processed with numerical control equipment to ensure that no matter where the two impellers are rotated, a certain small clearance can be maintained under the condition that the distance between the two impellers is constant, so as to ensure that the gas leakage is within the allowable range.

进口罗茨风机The two impellers rotate in opposite directions. Because the clearance between impellers and impellers, impellers and casings, impellers and wallboards is very small, a vacuum state is formed at the air inlet. The air enters the air inlet chamber under the action of atmospheric pressure. Then, two of the blades of each impeller form a seal chamber with wallboards and casings. The air in the air inlet chamber is continuously taken to the exhaust chamber by the seal chamber formed by two blades during the rotation of the impeller, Because the impellers in the exhaust chamber mesh with each other, the air between the two blades is squeezed out. In this way, the air is continuously transmitted from the air inlet to the air outlet, which is the whole working process of Roots blower.

进口罗茨风机characteristic:

Due to the adoption of a two blade rotor structure and a reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise.

The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is unchanged, and the fan can operate continuously for a long time.

The fan has large volume utilization rate, high volume efficiency, compact structure and flexible installation methods.

Complete models can meet the needs of different users for different purposes.

进口罗茨风机Operating conditions:

1. The steam inlet temperature of the conveying medium shall not be higher than 40 ℃.

2. The content of particles in the medium shall not exceed 100mg/m3.

3. During operation, the bearing temperature shall not be higher than 95 ℃, and the lubricating oil temperature shall not be higher than 65 ℃.

4. The operating pressure shall not be higher than the pressure rise range specified on the nameplate.

5. The clearances between the impeller and casing, impeller and side plate, impeller and impeller of Roots blower have been adjusted in the factory. The clearance shall be ensured during reassembly.

6. When Roots blower is running, the oil level of main oil tank and auxiliary oil tank must be in the middle of the oil mirror.

7. Check whether there are places where the inlet and outlet connections are not fastened, and whether the supporting parts of piping are complete. For the blower and vacuum pump that need cold water, check whether the installation of cold water meets the requirements.
