Jet Fan-Guangdong Jet Fan-Jin Blower Group Company:Tianjin fan , Tianjin blower , Tianjin fan
Fans used in the Jin blower group-sewage treatment plants are:
1. Sewage treatment fan-Centrifugal fan If the load requires a constant pressure effect, use a centrifugal fan. Because the centrifugal fan is a constant pressure fan, the main parameter of the work is the wind pressure. The output air volume changes with the changes of the pipeline and the load, and the wind pressure does not change much. Centrifugal fans have low wind pressure. The air compression process is usually carried out under the action of centrifugal force through several working impellers (or several stages). Centrifugal fans belong to square torque characteristics, while roots fans basically belong to constant torque characteristics.
2. Sewage treatment fan-Rotary fan, Roots blower is generally larger in air volume and higher in pressure. Similarly, Roots fan is also very noisy. If the air volume is required to be small, the noise requirements are relatively high. Yunnan jet fan Rotary blower is selected. Rotary blower is also a constant flow fan. The main parameter of work is air volume. The output pressure changes with the change of pipeline and load. The air volume changes little. Rotary fan is variable volume compression. Features are: low speed, low noise, low vibration, efficiency, high energy saving.
With the advancement of science and technology, the quality of technological innovation fans is also continuously improved. Jiangsu Jet Fans and Jin Blower Group have accumulated many years of experience and the training of technical personnel to create high-quality brand services and after-sales services for customers. At the same time, thank new and old customers for their strong support and trust.
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 spray painting, special attention must be paid to avoid poor paint 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 very important for the spray paint quality of the fan, so the ground dust and surrounding objects must be cleaned; then the pressure of the air pump should be adjusted to not less than 4MPa, the Hubei jet fan, and the spraying device and objects should not exceed 30cm.
3. The paint used for centrifugal fan spraying must be matched according to a certain proportion in advance. Basically, it is necessary to ensure that the viscosity of the paint meets the technical requirements and that there are no quality defects such as leakage spray, bubbles, orange peel, etc. after 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.
Development direction of fan technology: high working efficiency and low noise
With the continuous development of science and technology, people have higher and higher requirements for the use of fans. As far as the current development trend of foreign fan technology, it will continue to increase the capacity of fans, improve efficiency, miniaturization at high speed and low noise. Direction.
Large fan capacity continues to increase. The scale of various industrial installations is becoming larger and larger. Objectively, the capacity of various types of fans is also continuously increasing. Large fans will be welcomed in the market in the next few years.
efficient. To improve efficiency, ternary flow impellers have been used more and more widely in fans. The development of other special-purpose fans such as diagonal flow fans will be more marketable.
High-speed miniaturization. With the use of ternary flow impellers for various types of fans, the pressure can be increased while the efficiency is improved. Therefore, under the same conditions, the outer diameter of the impeller can be reduced by 10% to 30%, thus achieving the dual effect of reducing the volume and weight. Increasing the speed is also one of the important ways to miniaturize the fan.
Low noise. Fan noise is one of the main sources of noise pollution in industrial production. The fan's large size and high speed make the noise problem very prominent. For low frequency noise, the fan mainly improves the structural design of the fan to reduce the body noise. If the jet fan fails to meet the requirements, measures such as installing a muffler can be taken.
In summary, these technologies are not only the future development trend of foreign wind turbines, but also the technical efforts of the domestic wind turbine industry.
