Second, use:
This machine is suitable for factories, mines and gas station gas pressure furnace. Coke Oven. LDG pressure and ammonia. Biogas and other gases stringent airtightness.
Three structural features:
This type of fan is a plate welded monolithic structure, mainly in the following components:
1. Impeller The impeller is the heart of the entire wind turbine, so the aircraft airfoil according to the new high-efficiency fan theory to optimize the design, made of stainless steel or alloy, respectively, according to different needs, and has good corrosion ability and sufficient strength After forming the impeller, the static. dynamic balance correction, accuracy G4 level (higher than the national standard G6.3 level).
2, chassis with high-quality carbon steel and welded the whole base, ensure the machine's rigidity, epoxy coated inside the casing, in order to enhance the corrosion performance; the upper side set G3 / 4 'steam pipe connection lower set G3 / 2 'drain valve; outlet flange fan standard flange, to facilitate users to pipe connections.
3, seal groups. The main soft packing seal and centrifugal seal, no wearing parts within the sealed structure is very simple, the effect is particularly reliable, easy to replace.
4, the motor. This machine supporting or explosion-proof motor Y series motor, motor explosion-proof rating dⅡBT4, protection class IP44. Four performance parameters:
