The majority of components of energy-saving industrial fans are pre-assembled by the manufacturer before leaving the factory. Therefore, on-site assembly at the customer's location only requires integration and assembly of the completed parts. It is important to strictly follow the assembly requirements during on-site assembly to avoid increasing the workload.

Here are the guidelines for assembling energy-saving industrial fans:

  1. Before assembly, inspect and clean the dimensions, accuracy, and mating surfaces of the components that need to be assembled. The assembly must be performed according to the standards and assembly sequence.
  2. Cleaned parts and components should be placed according to the assembly or disassembly procedure and effectively protected. Oil, debris, and waste cleaning agents should not be dumped randomly and should be disposed of according to relevant environmental regulations.
  3. When tightening bolts, use a wrench. Avoid using impact methods or exceeding the permissible stress of the bolts. When multiple bolts or screws are used to fasten the same assembly, tighten them in a crosswise, symmetrical, and uniform manner. If there is a locating pin, start tightening from the bolt or screw closest to the pin. The contact between the bolt head, nut, and the connected part should be tight. If there are specific requirements for contact area and gap, they should be inspected according to the specified requirements. After tightening the bolt with the nut, the bolt should protrude 2-3 thread pitches, and its bearing surface should be flush with the fastened part. After tightening countersunk screws, they should be recessed into the component and not protrude. If there are requirements for locking, perform the locking process after tightening. When using double nuts for locking, install the thin nut first, followed by the thick nut. Using two identical washers under each nut is prohibited.
  4. For the assembly of precision bolts and high-strength bolts, the dimensions and accuracy of the bolt hole should be checked according to the design requirements. When assembling stainless steel, copper, aluminum, and other materials, anti-seize compounds should be applied to the threaded part.
  5. Assembly of locating pins: The type and specifications of the pin should meet the requirements in the technical documentation. When assembling the pin into the pinhole, lubricating grease or an anti-seize compound should be applied. Avoid subjecting the pin to load during assembly and choose the appropriate method based on the condition of the pin.
  6. The positions of all assembled parts should strictly follow the instructions specified in the technical documents. Carry out assembly inspections accordingly.
  7. After all, components are assembled, they need to be placed in the packaging box according to the specified position requirements. Take measures to prevent squeezing or damage during transportation and provide external protection.

The HVIST fan was invented by a joint venture between a US and a Chinese company in 1999. After almost 20 years of development, various industrial fans with different numbers of blades have emerged. Currently, domestically and internationally, industrial fans mainly come in three-blade, four-blade, five-blade, six-blade, and eight-blade configurations. In theory, the more blades a fan has, the greater the airflow. However, since industrial fans are generally larger in size, more blades also mean more weight and increased safety risks. Therefore, it is necessary to strike a good balance between airflow and quality. Currently, industrial fans with five or six blades are most popular on the market. These two types are also the main products promoted abroad and have been market-certified for over a decade. As long as manufacturers strictly require high quality and safety for the blades, they can meet market demand.

With the promotion of nationwide fitness, various communities have built indoor basketball courts of different sizes. However, the large span, high height, and relatively sealed building structure of basketball courts pose great challenges to ventilation and cooling. In recent years, many venue constructors have found that large fans (big ceiling fans) can perfectly solve the ventilation and cooling problems, which are tricky for indoor basketball courts.
