Analysis and Treatment of Axial Fan Vibration

2021-08-20

Axial-flow fans, with their advantages such as large airflow, small starting torque, and strong adaptability to changes in duct systems, are gradually replacing centrifugal fans as the mainstream choice. Axial-flow fans come in two types of blade adjustment mechanisms: adjustable blades and fixed blades. In adjustable-blade axial-flow fans, operating conditions can be altered by changing the angle of the working blades. These fans feature no interception losses, resulting in high efficiency and the ability to avoid instability under low-flow conditions. However, they have a complex structure, and their performance is significantly influenced by the stability and adjustability of the regulating mechanism. Consequently, they demand high reliability and precision in manufacturing, making them prone to failures. For these reasons, they are typically used only for blowers and primary air fans.

The waterstop has excellent isolation performance.

The water-blocking baffle is an essential component of air-conditioning terminal units. When used in conjunction with air conditioners, it serves the function of separating vapor from water. The water separator is a key component of air-conditioned rooms and can be used at both high and low fan speeds. It can be made from fiberglass-reinforced plastic or PVC materials, offering advantages such as low resistance, light weight, high strength, excellent corrosion resistance, outstanding aging resistance, superior water-vapor separation performance, easy cleaning, and long service life. The water-blocking baffle is primarily manufactured from PVC resin, ensuring that it maintains appropriate rigidity, impact resistance, anti-aging properties, corrosion resistance, and fire-retardant characteristics. Continuous extrusion molding successfully preserves the baffle’s density and precise geometric dimensions, and its length can be customized to any desired length.

Flood Control and Waterstop Performance Analysis

Flood barriers, also known as flood-proofing boards, waterproof boards, flood gates, sluice gates, water-stopping boards, water-retaining walls, water-stopping doors, flood-resistant panels, or modular flood walls, primarily serve to prevent water from entering areas that require waterproofing and to protect entrances and exits that need to remain watertight—such as basements, warehouses, stores, riverbanks, and underground shopping malls. After years of continuous improvement and upgrades, highly reliable flood-control products are now available, effectively preventing rainwater from seeping in.

Uses and Features of Waterstop Boards

The water baffle is an important component of the terminal unit in central air-conditioning systems. It works in conjunction with the central air-conditioning system to separate steam from water. As a key component of air-conditioned rooms, the water baffle can be used at both high and low air-flow rates. It can be made from fiberglass reinforced plastic or PVC materials and features low resistance, light weight, high strength, excellent corrosion resistance, outstanding aging resistance, superior steam-water separation performance, easy cleaning, and long service life.

Product characteristics of spray drainage

Excellent electrical insulation properties. The coating used in the spray-rinse system, which is made of epoxy resin—a thermosetting resin—possesses outstanding antistatic performance. It exhibits excellent stability, does not chemically react with most substances, and offers superior corrosion resistance. The coating demonstrates strong adhesion to surfaces, exhibiting exceptional bonding strength on polar substrates such as metals, ceramics, glass, concrete, and wood.

Use and Maintenance of Axial Fans

2021-05-26

Like other types of fans, axial-flow fans also require maintenance during operation to ensure they perform optimally and to extend their service life. Therefore, fan maintenance has always been a key concern for most users. To achieve effective maintenance, what specific steps should be taken during the maintenance phase of an axial-flow fan?
