Exhaust gas treatment fanWhat are the notable usage characteristics?

　　China's emission requirements are becoming increasingly stringent, and the standards for organic waste gas emissions are also becoming stricter. In the past, exhaust gas treatment systems were installed casually with a simple fan, and upon inspection, the entire system became a mere decoration. The treatment efficiency, reasonable efficiency, and effectiveness of the exhaust gas treatment system are now critical. With the strengthening of online real-time monitoring and environmental control, if the exhaust gas treatment does not meet standards, there will be risks of fines and production stoppages. Therefore, whether organic waste gas can meet emission standards has become a key aspect of a company's survival.

　　CentrifugalExhaust gas treatment fanWhat are the common misconceptions about maintenance?

　　Install the fixed end and free end covers on the bearing end cover of the centrifugal fan (a total of 8).

　　Reason: The manufacturer designed a non-locating bearing at the tail to accommodate the thermal expansion caused by the high-temperature environment of the centrifugal fan shaft. During installation, the locating bearing should be strictly positioned, and the expansion side of the free bearing should not be restricted. If installed incorrectly, the free expansion of the shaft will be limited, which can easily lead to equipment accidents.

　　Correct practice: Based on the length of the bearing end cover inserted into the flange, install the upper and lower end covers with the shortest flange on the Z far side, while ensuring that other end covers are reliably positioned and the thickness of the sealing ring is appropriate.

　　When aligning equipment, tighten or loosen the anchor bolts to meet the relevant precision requirements, or use shims for adjustment, but add shims only between the motor or hydraulic coupler and the base plate.

　　Analysis: Tightening and loosening the anchor bolts of the spray fan can lead to uneven pre-tightening force among the anchor bolts, which can easily damage individual anchor bolts during operation. In subsequent maintenance, re-tightening can easily damage the adjusted installation dimensions. The motor base plate, hydraulic coupler, and base plate should be regarded as a whole, and shims should only be added between the base plate and the foundation shims.

　　Correct practice: Use shims to adjust the installation dimensions, add shims between the base plate and the foundation shims, and tighten the anchor bolts to ensure that the force on the bolts is basically uniform.

　　CentrifugalExhaust gas treatment fanThe bearings are lubricated by an oil pump, and normally operating bearings generally do not lose oil. Therefore, when the oil thrower ring is damaged, it is often inconvenient to install and people are reluctant to replenish it.

　　The function of the oil thrower ring is to lift the oil ring from the oil pool in the bearing box during unexpected power outages or short-term oil station failures, providing a certain amount of bearing oil to ensure continuous rotation without damage. Therefore, centrifugal waste gas treatment fan manufacturers are definitely indispensable.

　　Calculation method for the air volume of exhaust gas treatment equipment

　　When selecting exhaust gas treatment equipment, we need to pay attention to air volume and air pressure. Even when calculating air volume, we need to consider air resistance. Generally speaking, all equipment has air resistance, and different equipment has different air resistance. For example, the air resistance of an activated carbon adsorption box is much greater than that of a photo-oxidation catalytic device, so air pressure is very important; otherwise, the selected air may directly absorb waste gas.
