Problems solved by technology

Although the structure of the high-pressure blower is relatively compact, since the bearing of the blower is installed at the front end of the air barrel, liquids such as rainwater entering the air barrel can easily enter the motor along the output shaft of the motor and cause damage to the motor.

Abstract

The invention relates to a high-pressure blower, and belongs to the technical field of blower equipment. The high-pressure blower comprises a wind barrel and a motor, wherein the output shaft of the motor extends into the wind barrel, a wind blade is fixedly connected to the extending-in end of the output shaft, a circular bearing cover plate is fixedly connected to the outer side surface of the wind barrel on one side facing to the motor, a through hole is formed in the position of the center of a circle of the bearing cover plate, a bearing seat is arranged on the side surface of the bearing cover plate on one side facing to the motor and is arranged around the through hole, and a bearing is fixedly connected to the inner part of the bearing seat. The bearing cover plate and the bearing respectively consist of the following components by weight percent: 0.12 to 0.15% of C, 0.25 to 0.30% of Si, 0.50 to 0.80% of Mn, 0.50 to 0.80% Cr, 0.05 to 0.10% of Mo, less than or equal to 0.20% of Cu, less than or equal to 0.10% of Ni, less than or equal to 0.025% of S, less than or equal to 0.025% of P, and the balance of Fe. The high-pressure blower has the advantages of rational design and long service life.

Description

technical field [0001] The invention belongs to the technical field of blower equipment and relates to a 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 blowers, h...
