As optimization, be provided with between the independent case body plate of six faces of said air box and split bindiny mechanism.The independent case body plate of six faces is independently detachable, uses dismountable sunk screw fixing dead between the independent case body plate of six faces each other, and overlapping on the face between plate body and plate body, shuts with rubber weather strip.The security level of whole wind cabinet can be improved like this, and the noise of box house blower fan, electromechanics vibration generation can be eliminated.
As optimization, the withstand voltage shockproof beam of said blower fan bottom is a Rubber shock-absorbing pad.The Rubber shock-absorbing pad that uses polylith plays good buffer function to blower fan shockproof makes blower fan remain the smooth running state.
As optimization, the outlet expansion joint in said blower fan outlet port adopts teflon as carrier.Select for use high temperature resistant, erosion-resisting teflon can prolong the working life of product as the carrier of expansion joint; And when design, consider enough amount of deformation; Satisfy the displacement that unit vibration, alignment error cause, fan outlet and air box physical efficiency are played the effect of buffering.
As optimization, said air box intake grill direction is provided with the independent fan box import bloop of three covers.To the air inlet place
Play the effect of abating the noise.
As optimization, said fan box intake grill place is provided with dismountable import filter screen, and said filter screen adopts the stainless steel steel wire, and filter screen inside is embedded with nonwovens.Can prevent effectively that dust, fine particle from getting into casing, pollutes the cavity in the case.Be added with differential pressure indicator before and after the removable filter net simultaneously, when the inlet outlet pressure differential of filter screen reaches certain value, can embedded nonwovens be released, after the flushing of dust impurity is dried, still can put into filter screen and continue to use.
As optimization, said blower fan is a high efficiency, the nuclear power authentication blower fan of low noise.The impeller selection of this multi-functional nuclear power blower fan is good, through comprehensively proving, chooses the higher leveled material of strength grade before material is used; The impeller aeroperformance is good, adopts advanced aerodynamic model, has the characteristics of high efficiency, low noise, and the strict control of the casing outlet velocity of nuclear power blower fan guarantees very low noise and vibration.
Beneficial effect: the multi-functional nuclear power blower fan of the utility model integral body has adopted shock absorber bracket, withstand voltage shockproof beam, outlet expansion joint, has avoided transfer of vibration, has reduced noise, has functions such as anticorrosion, shockproof, super-silent.
