◆ seal 1. Roots blower fan with a sealing system to ensure the free flow of oil and prevent oil pollution. 2. sealed with labyrinth seals, metal movement ring, oil slingers and balanced ventilation holes. To ensure that the air blower cavity, with minimal leakage, while the lubricating oil can not be on both sides of the fuel tank into the fan chamber to ensure that the outlet air clean. 3. The shaft seal with two lips Vladimir rubber seal. For special gases, other sealing methods can be used, for example: carbon ring and mechanical seal Roots fans are constant torque high pressure air, using a pair of gears meshing with each other air intake and exhaust, wide 西罗茨 fan, its exhaust pressure much lower than the air compressor, blower, not enough to drive cylinders and pneumatic tools. Commonly used in water treatment plant aeration tank into the pool inject high pressure air, coal dust gas emissions, that require high oxygen pressure of the occasion pond, smelting blast furnace. Roots blower characteristics: 1, a large fan capacity utilization, Guangdong blower, high volumetric efficiency, and compact structure, flexible installation. 2, fans Viton seals made of imported materials, high temperature, wear-resistant, long service life. 3 models range to meet the needs of different users for different purposes.
