Use classification of fan:
Fans can also be divided into multiple types according to different purposes, such as smoke exhaust fans, air conditioning fans, roof fans and so on. These fans are designed for special purposes, so they are different from ordinary fans in terms of shape, material and function. For example, roof fans can be designed to be bidirectional reversible air supply and exhaust.
Other classifications of fans;
According to the different number of air blowers, the fans can be single-stage, double-stage and multi-stage fans. For example, Roots fans are typical multi-stage fans. According to the structure of the design and the installation position of the motor, the high-pressure centrifugal fan can also be a fan-type fan and a fan-out fan.
After the centrifugal fan is assembled, it needs to be spray-painted, mainly to improve its cleanliness and improve its anticorrosive performance. Therefore, once the painting effect is not good, it will cause certain effects on the fan, such as shortening its service life, easy to be corroded, and speeding up the damage of various parts. Therefore, when painting, Shanghai fans must pay special attention to avoid poor painting quality.
1. Before spraying the centrifugal fan, it must be handled in place, which specifically involves degreasing and decontamination. At the same time, it is necessary to confirm that the welding and the surface of the parts are smooth. No appearance defects are allowed. Good surface packaging.
2. Of course, the cleanliness of the environment is also important for the paint quality of the fan. Therefore, the dust on the ground and surrounding objects must be cleaned; the pressure of the air pump should be adjusted to not less than 4MPa, and the spraying device and objects should not exceed 30cm.
3. The paint used for centrifugal fan spraying must be matched in a certain proportion in advance. The centrifugal fan basically guarantees that the viscosity of the paint meets the technical requirements and that there are no quality defects such as leaking spray, bubbles, orange peel, etc. after the spray painting is completed. After the fan finishes the rust-proof paint twice and finishes the paint twice, it is ensured that the appearance of the fan is bright, smooth, and has good adhesion, which meets the technical requirements.
4. Due to the hidden safety hazards in the production process of the motor wheels, V-belts and other moving parts of the centrifugal fan, it should be sprayed with eye-catching paint. The dried or naturally dried machine is riveted with a label and a product nameplate to ensure that the riveting is firm, not subject to vibration and deformation, and consistent with the product.
Therefore, a centrifugal fan can run normally, and it can not be used for a long time without problems in all aspects, such as painting, installation, operation, and post-maintenance. Long-lasting, stable, and safe to use.
Selection basis and method of high temperature fan
High-temperature fans are generally made of high-quality stainless steel and titanium plates as materials. Fan manufacturers can use different materials according to different temperatures to ensure stable and long-term operation in production. 2. The drive shaft of the fan must be specially treated, otherwise it will be deformed easily during high temperature operation, which will cause the fan to be paralyzed. 3. The fan's transmission box must be insulated from the fan casing and at the same time the bearing box Internal water cooling system and air cooling system are used at the top. 4. The fan's belt must choose high-temperature resistant high-quality belt. 5. The fan casing, air inlet, and external areas in contact with the gas are all treated with heat insulation. The above points are the accumulation of many years of experience in fan technology for Shandong Lanneng Environmental Protection Technology Co., Ltd., and I hope to share with you in the future.
