[Purification Equipment Co., Ltd., Tianjin Jinzhong Ji HVAC recommend to you the star product --4-72 centrifugal fan centrifugal fan] fault repair transmission parts wear is often seen equipment problems, including the blower bearings bit worn bearing chamber, blower shaft Bearing bit wear. Centrifugal fan for the failure of traditional repair methods are welding, thermal spraying, brush crossing, etc., but have certain drawbacks: high temperature welding thermal stress generated can not be completely eliminated, could easily lead to material damage, resulting in part appears bent or broken; The coating thickness is restricted by the electric brush, centrifugal fan is easily peeled off, and the above two methods are used to repair metal metal, can not change the "hard on hard" with the relationship, under the combined effects of wind power each chassis, still cause package Wear rubber rollers again. To solve the above problems of contemporary Western countries use more polymer composites repair methods, and the application of more American blessing blue world technology system, which has superior adhesion, excellent compressive strength and other comprehensive performance, free-free disassembly machine processing. Neither welding thermal stress on the repair thickness is not limited, while products with metallic materials do not have a concession, can absorb impact shock device, to avoid the possibility of re-wear at home against the centrifugal fan troubleshooting applications also gradually replace the traditional methods. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --HTF fire exhaust fan] installation process a comprehensive sample of fans familiar, familiar fan specifications, form of the impeller rotation direction and the direction of the air flow in and out, etc., Fans should be checked before installation whether the collision phenomenon impeller purify air box, and conduct a comprehensive inspection of the components, the attachment is complete, whether the firm connection of the components, carefully check whether the blades due to shipping damage or deformation air enclosure, or should be before installation repair. 2, there should be a separate duct connecting the fan support import and export, plus the weight of the pipe is not allowed on the blower parts, turbine installation should pay attention to the horizontal position of the fan, the fan and the ground connection to the combination of surface and out of the wind pipe exhaust air box should be adjusted to make it a natural fit, not be forced to join. 3. After installing the fan, hand or lever Stubbs impeller, check whether there is too tight or collision phenomena, whether or interfere with the rotation of items, no abnormal phenomenon, the only test run, the exposed parts of the wind opportunity gearing should protective cover (user-supplied). Such as when the fan is not connected to the inlet pipe, also need to purchase protective nets or other safety devices (user-supplied). 4, the fan wiring must be accurate and reliable, the fan housing should be properly grounded, grounding must be reliable. Fan power supply must be complete and comply with the relevant requirements. Electrical wiring must have electrical wiring expertise.
