Description

Aerospace fan shell convenient to detach

Technical Field

The utility model relates to a fan technical field, in particular to spaceflight is with convenient to detach's fan shell.

Background

The fan is a driven fluid machine which increases the pressure of gas and discharges the gas by means of input mechanical energy. The blower is a Chinese habit abbreviation for gas compression and gas conveying machinery, and the blower generally comprises a ventilator, a blower and a wind driven generator. Fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, and for ventilation and draught of boilers and industrial furnaces and kilns; cooling and ventilation in air conditioning equipment and household appliances; drying and selecting grain, wind tunnel wind source and air cushion boat inflating and propelling. Gas compression and gas delivery machines are machines that convert rotational mechanical energy into gas pressure energy and kinetic energy and deliver the gas out. The main structural components of the fan are an impeller, a shell, an air inlet, a bracket, a motor, a belt pulley, a coupling, a silencer, a transmission part and the like. The unpowered ventilator utilizes natural wind force and air heat convection caused by indoor and outdoor temperature difference to drive the turbine to rotate, so that the hot air which is not fresh in the room is discharged by utilizing centrifugal force and negative pressure effect. The fan is related to the transmission and distribution energy consumption of the system and is a very critical part for building energy conservation. According to the years of fan detection of the national air conditioning equipment quality supervision and inspection center, the problem exists in many fans under rated working conditions, so that the fans need to be produced and manufactured strictly according to the product standard requirements. When the fan starts to work, the vibration of the bearing part is small, but with the increase of the running time, dust in the fan can be unevenly attached to the impeller, the dynamic balance of the fan is gradually damaged, the vibration of the bearing is gradually increased, and once the vibration reaches the maximum value of 11mm/s allowed by the fan, the fan must be stopped for repair. Since this is already very dangerous, the user is not forced to use it by tens of millions. When the vibration of the fan is close to a dangerous value, the vibration measuring instrument gives an alarm.

The existing aerospace fan shell is complex to disassemble and inconvenient.
