[0001] The invention relates to a blower, in particular to a piston type two-stroke blower. Background technique
[0002] At present, centrifugal blowers are used in most occasions. The working principle of centrifugal blowers is similar to that of centrifugal fans, except that the air compression process is usually carried out by several working impellers (or several stages) under the action of centrifugal force. The blower has a high-speed rotating rotor. The blades on the rotor drive the air to move at high speed. The centrifugal force makes the air flow in the involute-shaped casing along the involute to the fan outlet. The high-speed airflow has a certain wind pressure. Fresh air enters through the center of the casing to replenish it.
[0003] It is particularly worth mentioning that most fans have the phenomenon of large horses and small carts during use, and due to changes in production and technology, it is necessary to frequently adjust the flow, p...
