Product Overview: GYF High Temperature and High Pressure Fiberglass Centrifugal Fan

Zhejiang Tianhong fiberglass centrifugal fan adopts high-quality vinyl ester resin and advanced production technology, with strong anti-corrosion function. The compact impeller design structure meets the high-speed operation of the fan. The blade design has a large air volume, light weight, high energy efficiency, and long service life. Replacing the outdated production process of fiberglass wrapped iron to solve the problem of low air volume and easy disassembly of ordinary fiberglass impellers. The impeller can be customized with 8-16 different quantities of models according to the customer's air volume.

·The debugging of the fiberglass centrifugal impeller adopts a dual combination of dynamic balance and static balance, and the dynamic balance meets the ISO-1940 G2.5 level.
·The fiberglass centrifugal fan adopts a double-layer base with a high-efficiency shock absorber installed in the middle. The vibration value meets the requirements of ISO-2372 4.5 level or above, significantly reducing the vibration of the fan and improving the overall service life of the fan.
·The fiberglass centrifugal impeller adopts advanced foreign technology, optimizes the manufacturing size and angle of the impeller, and adopts Vinglester vinyl ester special grade resin integrated molding to make the structure of the fiberglass centrifugal impeller rigid Wind volume and pressure Strength equivalent to steel impeller, impeller
The self weight is lighter than that of steel impellers, improving the energy efficiency of the fan. Solve the problem of traditional fiberglass impellers using outdated processes such as fiberglass wrapped with iron.
·The impeller shaft of the fiberglass centrifugal fan adopts a split structure, fully enclosed and covered Install firmly Easy disassembly and maintenance.
·The fiberglass centrifugal fan adopts an oil bath bearing box to protect the bearings and shaft from corrosion by acidic and alkaline gases. Combined with the application of American style pulleys and imported belts, it extends the service life of the fan and reduces the frequency of failures. Fan motors and bearings can be selected according to customer needs
Use imported or domestic brands.
·The fan is equipped with maintenance ports and drainage holes on the outside, which facilitate the inspection and cleaning of the impeller and prevent the accumulation of dirt on the impeller.
·Provide factory measurement of performance and vibration, provide test reports, prevent faults before they occur, and ensure that the fan operates at its best condition.
·A complete product information book, with all spare parts, consumables, performance, operating range, etc. documented and listed.
·Provide a fan maintenance manual to standardize maintenance work, retain maintenance records, and facilitate handover.
