Double-section type high-pressure blower

Abstract

The invention provides a double-section type high-pressure blower, belongs to the technical field of fan equipment, and solves the problem that existing double-section type high-pressure blowers cannot be applied to a single impeller. The double-section type high-pressure blower comprises a motor, a front wind barrel and a rear wind barrel. A rear rotary shaft is rotatably connected into the rear wind barrel and is fixedly connected with the output shaft of the motor. Rear blades are fixedly connected to the rear rotary shaft. A bearing bush is fixedly connected between the motor and the rear wind barrel. A rear bearing is fixedly connected into the bearing bush. The output shaft of the motor penetrates the rear bearing. A front rotary shaft is rotatably connected into the front wind barrel. One end of the front rotary shaft is detachably fixedly connected with the free end of the rear rotary shaft. Front blades are fixedly connected to the front rotary shaft. The double-section type high-pressure blower has the advantages that the blower can be turned into a single-stage blower by demounting the front blades, and the blower is flexible and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of fan equipment and relates to a double-stage high-pressure blower. Background technique [0002] The blower is mainly composed of motor, air filter, impeller, air chamber, base and other components. The air is sucked, compressed and discharged by the volume change between the blades. Since the impeller runs without friction in the body and does not need lubrication, the discharge The gas does not contain oil, and it is an ideal source of pneumatic conveying gas for chemical, food and other industries. When in use, with the change of pressure, the change of flow rate is very small, but the flow rate changes with the speed, so the selection range of pressure is very wide, and the choice of flow rate can meet the needs by selecting the speed. There are various types of blowers, which can be divided into Lu-type blowers, high-pressure blowers, etc. Among them, high-pressure blowers, also called high-pressure ...

AI Technical Summary

Problems solved by technology

The one-piece gearbox, as a part of the blower cylinder, can increase the impeller speed to obtain higher pressure. At the same time, the axial impeller cover seal can reduce the gap and improve the reliability in high-pressure applications, but due to the above blower Multiple impellers are fixedly connected to the rotating shaft. When the motor starts, multiple impellers work at the same time. When the power demand for the blower is low, the use of the above blower is wasteful.
