Impeller passed high standard dynamic balancing, ensuring stable running of fan.
Running test and vibration value test for fans after finishing manufacturing, ensuring running reliably.
Impeller of annealing treatment, completely eliminating structure of internal stress when welding, ensuring impeller appearance won’t occur creepage and flaw.
The welding line of impeller and main shaft passed ultrasonic flaw detection, ensuring no defect of welding and materials, guarantee strength.
Can flexibly adjust fan’s volume and pressure in running by air damper. Can also adjust fan’s pressure and volume by changing the fan speed via matching variable frequency motor.
Regarding to material of impeller and main shaft, we will choose high strength carbon steel, low alloyed steel, High temperature resistant alloy steel, High temperature resistant high strength alloy steel according to different medium temperature and running speed, ensuring the impeller and main shaft keeping reliable strength in high temperature.
Using liquid lubricating oil, no need to open bearing housing when changing or filling lubricating oil.Easy to observe the lubricating oil’s quality and stock through inspection window on the bearing housing body.
Bearing housing adopt labyrinth type mechanical seal, unique design of spill prevention of inner, venthole design on top, commissure coated with sealing grease, completely eliminating bearing housing oil leak.
