The technical solution of the utility model is:
The multistage blowers of air inlet through hollow shaft, comprise inlet casing, inlet end bearing support, bearing, fan rotor, intermediate casing, the casing of giving vent to anger, air induction mast and suction port, fan rotor is arranged on inlet casing, in the blower fan stator that intermediate casing and the casing of giving vent to anger form, the end of fan rotor main shaft arranges inlet end bearing support and the bearing of mutual coupling, inlet end bearing support outer cover air induction mast, air induction mast is provided with suction port, suction port is arranged on air induction mast, on the axis of inlet end bearing support and fan rotor main shaft, blower fan is provided with suction port air inlet through hollow shaft by air induction mast, in the time of air intake, blower fan inlet end bearing support and bearing are carried out to wind cooling temperature lowering.
Described inlet end bearing support is connected with air induction mast by several gussets, and the intake grill of air induction mast is provided with inlet end flange, can be connected with channel bend easily; The other end of air induction mast is provided with adpting flange, is connected with inlet casing.
Described gusset section configuration is arbitrarily, such as rectangular section, circular section etc.
Described inlet end bearing support is spherical shape towards the appearance of suction port, has both been convenient to the manufacture of inlet end bearing support, is convenient to again air intake; Space between air induction mast and inlet end bearing support and gusset has formed the air intake passage of multistage blowers.
Described inlet casing, has removed traditional air intake passage, has simplified the structure of inlet casing, makes casting, processing easier, only plays being connected to form blower fan first order blade wheel chamber with intermediate casing and being connected with inlet end bearing block flange the effect of playing support rotor.Shorten the length of fan shaft simultaneously, reduced the distance between spring bearing, removed the sealing between inlet end bearing and inlet casing.
The beneficial effects of the utility model are: solved the larger windage problem that multistage blowers produce by the vertical air intake of the air intake pipe on inlet casing, solved inlet end bearing support and the bearing problem that cools, simplified the structure of inlet casing simultaneously, it is easier to make to cast, process, shortened the length of fan shaft, reduce the distance between spring bearing, improved intensity and the rigidity of fan shaft, removed the sealing between inlet end bearing and inlet casing.With the inlet end bearing support of air inlet function, can accomplish no matter to process its section of air force in addition and be circle, removed the circumference adapter of processing the blower fan import that air quantity is large, if run into user's specific (special) requirements left and right horizontal air intake or vertical upper air inlet, add a punched bend and can meet customer requirements.
