Abstract

The invention relates to a centrifugal fan convenient to install and maintain. The centrifugal fan comprises a shell, a main shaft rotationally connected to the shell, an impeller fixedly connected to one end of the main shaft and positioned in the shell, and a motor connected to the other end of the main shaft, wherein a plurality of inserting grooves and a plurality of clamping grooves communicating with the inserting grooves are formed in the side, facing the motor, of the shell. The centrifugal fan convenient to install and maintain further comprises a fan position adjusting mechanism used for adapting to pipeline connection. According to the centrifugal fan, the shell capable of being rapidly disassembled and assembled is used, when the centrifugal fan breaks down and needs to be maintained, the shell can be rapidly disassembled, overhauling of the interior of the fan becomes easy, after overhauling is finished, the shell can be rapidly assembled back, convenience and rapidness are achieved, a first worm gear and a first worm are used for controlling a rotating disc to rotate, the shell is driven to rotate, thus the direction of an air outlet in the shell can be changed at will in the radial direction, and the air outlet can better adapt to pipeline connection.

Description

technical field

[0001] The invention relates to the field of centrifugal fans, and more particularly relates to a centrifugal fan which is convenient for installation and maintenance. Background technique

[0002] The centrifugal 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. The fan is widely used. According to the different air volume, its application fields are also different. With the development of science and technology With the development, people's demand for fans with large air volume is getting higher and higher. The following problems often occur in the daily use of centrifugal fans:

[0003] 1. When the centrifugal fan needs to be used, it is first necessary to use flexible pipes to connect the air inlet and outlet with the system air path, which requires a very high length for the flexible pipes. It is very troublesome to buy new flexible pipes, which needs to be shu...
