Fluid machine with high safety coefficient

Abstract

The invention relates to a fluid machine with a high safety coefficient. The fluid machine with the high safety coefficient comprises a fixed pipe, a protective net, a transmission shaft and at leastthree blades, wherein the transmission shaft and the fixed pipe are coaxially arranged, the transmission shaft, the protective net and the blades are all located in the fixed pipe, the blades are uniformly fixed on the transmission shaft in the circumferential direction by taking the axis of the transmission shaft as the center, the protective net is arranged at one end in the fixed pipe, a driving mechanism and at least two connecting mechanisms are arranged in the fixed pipe, the connecting mechanisms are uniformly distributed on the side, close to the transmission shaft, of the protective net by taking the axis of the fixed pipe as the center in the circumferential direction, the driving mechanism comprises a driving assembly, a transmission assembly and an auxiliary assembly, and the transmission assembly comprises a driving disc, a driven disc, a rotating shaft, a first bearing, a magnet block and at least two transmission units. The fluid machine with the high safety coefficientrealizes the function of driving the blades to rotate through the driving mechanism. Meanwhile, the safety is improved by the connecting mechanisms.

Description

technical field [0001] The invention relates to the field of fans, in particular to a fluid machine with a high safety factor. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling, as well as for ventilation and induction of boilers and industrial furnaces. Wind; cooling and ventilation in air-conditioning equipment and household electrical equipment; drying and sorting of grain, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0003] During the use of the existing fan, in order to reduce impurities from entering the fan, a protective net is installed at the air inlet of the fan. When the fan needs to...

Problems solved by technology

[0003] During the use of the existing fan, in order to reduce impurities from entering the fan, a protective net is installed at the air inlet of the fan. When the fan needs to be maintained and the protective net is removed, if the fan blade is still in the rotating state due to negligence Not only that, after long-term use of the fan, a large amount of dust will be generated on the blades, and the dust will affect the balance of the rotation of the fan's internal drive shaft and aggravate the wear of the first internal bearing. , which reduces the practicality of
