Abstract
The utility model relates to an electric multiple unit-dedicated centrifugal fan with a vibration absorber. The centrifugal fan comprises an air intake channel, impellers, a scroll casing, an L-shaped mounting plate and an electromotor. The centrifugal fan has the following characteristics: since the centrifugal fan is provided with the vibration absorber which consists of fan-mounting plates, conical shafts and polymer rubber sleeves, the centrifugal fan becomes an anti-shock-vibration centrifugal fan with a vibration absorber, which can damp vibration, and thereby, the vibration affection between the fan and the fan-mounting foundation can be effectively reduced.
Description
Technical field
The utility model is bright, and what relate to is a kind of centrifugal blower, is applicable to that particularly rail motor set use the centrifugal blower of band vibration damping equipment, belong to field of fluid machinery.
Background technique
According to the use condition of rail motor set, blower fan mounted thereto will be impacted, and this impact meeting produces harmful effect to blower fan, therefore require blower fan and being connected of rail motor set can suitably reduce the harmful effect of this impact to blower fan.Simultaneously, itself can produce the vibration of high frequency during the blower fan running, and this vibration also can produce harmful effect to the installation basis of blower fan, and the basis that also requires can suitably reduce blower fan and being connected of rail motor set blower fan is installed produces harmful effect.Conventional fan all is to reach this purpose by the simple vibration damping sealing gasket of extra installation, and vibration damping sealing gasket effect is undesirable, and since when installing not enough standard produce harmful effect on the contrary.
Summary of the invention
The purpose of this utility model is to overcome the deficiency and the defective of existing technology, provides a kind of and can effectively reduce shock and vibration to the rail motor set of the installation basis influence of blower fan and blower fan band vibration damping equipment centrifugal blower.
The technical solution of the utility model: a kind of rail motor set centrifugal blower of band vibration damping equipment, comprise air inlet duct, impeller, spiral case, L type mounting plate and motor, it is characterized in that described rail motor set are with being provided with by the blower fan mounting plate in the centrifugal blower that has vibration damping equipment, the vibration damping equipment that the axis of cone and polymer rubber sleeve are formed, its vibration damping equipment is to pass through bolt, nut and pad are fastened on the L type mounting plate, polymer rubber sleeve in the described vibration damping equipment is the I-shaped rubber bush of band center taper hole, the described axis of cone is provided with to install uses central shaft hole, blower fan mounting plate center is a funnel structure, its polymer rubber sleeve set is on the axis of cone, and the blower fan mounting plate is sleeved on the polymer rubber sleeve and constitutes vibration damping equipment.That is to say that vibration damping equipment is made up of interior raising molecule rubber between the axis of cone and the mounting plate; The utility model is that this damping pad is directly installed on the blower fan, becomes a kind of centrifugal blower that carries the protecting against shock vibration of vibration damping equipment.That is to say that vibration damping equipment is made up of raising molecule rubber between the axis of cone and the mounting plate;
This practical blower fan has adopted the advanced vibration damping equipment that carries, by conical surface axle construction, fill the reasonable Arrangement of TLTF-GJ-1 macromolecule silicone rubber, L type mounting plate, intermediate isolating mounting plate, make fan vibration speed be lower than 4.5mm/s, maximum deformation quantity in service is less than 0.5mm.
