Description

Pipeline buffer structure for preventing vibration of wind turbine

Technical Field

The utility model belongs to the technical field of the pipe connection, concretely relates to prevent pipeline buffer structure of fan vibration.

Background

The fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draught of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grains; wind tunnel wind source and air cushion boat inflation and propulsion.

The centrifugal ventilator mainly comprises: impeller, casing, shaft coupling, axle. The impeller is a main work-doing component for generating wind pressure and transmitting energy; the casing is mainly used for introducing gas and discharging gas, and simultaneously converting partial kinetic energy of the gas into pressure energy; the coupling is used for connecting the motor and the fan and transmitting torque; the shaft is provided with and fixes the impeller and is connected with the motor through the coupler.

When the impeller rotates, the gas between the blades of the centrifugal fan is subjected to centrifugal force to obtain kinetic energy (dynamic pressure head) to be discharged from the periphery of the impeller, and the kinetic energy is guided by the volute-shaped casing to flow towards the outlet of the fan, so that negative pressure is formed at the central part of the impeller, external airflow continuously flows in and is supplemented, and the fan can discharge the gas.

The fan can generate small-amplitude vibration in the using process, which cannot be avoided, and meanwhile, the vibration caused by the out-of-place matching caused by the abrasion of equipment, the overhauling and assembly and the vibration caused by the unbalance of the impeller in the using process can be generated because parts on the impeller are loosened, changed and colored or generate uneven corrosion and abrasion; solid particles in the working medium are deposited on the rotor; the new parts replaced in the overhaul are uneven in weight; the impeller is made of non-uniform materials; the machining accuracy has an error, an assembly deviation, and the like. The impeller is not balanced, and the impeller imbalance can be divided into dynamic imbalance (couple imbalance) and static imbalance (moment imbalance). The above conditions can increase the vibration of the fan, the operation of the fan is not influenced by the vibration, but the use of the surrounding connected equipment is influenced, and the connected equipment is damaged and loosened.
