Description

Bladeless superstrong high-efficient high pressure positive blower

Technical Field

The utility model discloses the creation relates to a centrifugal fan, especially a do not have traditional blade structure, has the high-efficient high pressure positive blower of superstrong wind pressure.

Background

The blower is used for compressing and conveying gas in ChinaThe habit of the feeding machine is shortened, and the fan depends on the input mechanical energy to improveGas (es)Machines for pressurizing and discharging gases, known as fans, include ventilators, blowers, wind generators, and the like.

The fans are classified into a turbine fan and a positive displacement fan according to the principle of action, the turbine fan compresses and delivers gas by rotating blades, and the positive displacement fan compresses and delivers gas by changing the volume of the gas.

The common turbine type fan includes two types of centrifugal fan and axial flow type fan, the centrifugal fan uses curved blades to throw air to the casing by centrifugal force, and the main parts of the centrifugal fan are casing, impeller, shaft, air suction port and exhaust port. When the centrifugal fan works, a power machine (mainly a motor) drives the impeller to rotate in the volute casing, and air is sucked from the center of the impeller through the air suction port. The pressure and speed of the gas are increased due to the power action of the blades on the gas, and the gas is thrown to the machine shell along the blade channel under the action of centrifugal force and is discharged from the gas outlet. The flow of gas in the impeller is mainly in a radial plane, so the impeller is also called a radial flow fan. With the progress and development of the times, people can not meet the requirements of pressure and air volume of the centrifugal air pump, and the noise of the centrifugal air pump is more and more troublesome in the factory.

The high-pressure fan is a fan with the wind pressure of 30 kPa-200 KPa or the compression ratio e = 1.3-3 under the design condition. When the impeller rotates, the gas is forced to move forwards and outwards under the action of centrifugal force, and the high-pressure fan forms a series of spiral movements. The air between the blades of the impeller rotates in a spiral accelerating way and sucks the air outside the pump body into the side groove through the air suction port, and after the air enters the side channel, the air is compressed and then returns to the space between the blades of the impeller to rotate in an accelerating way again. As the air follows a helical path through the impeller and side channels, each impeller blade increases in compression and acceleration, and as rotation progresses, the kinetic energy of the gas increases, causing a further increase in pressure of the gas passing along the side channels. When the air reaches the junction of the side groove and the discharge flange, the gas is forced out of the vanes and out of the pump body through the outlet muffler.

The air is pushed by the blades to be discharged outwards, and particularly, the air collides with the blades, so that energy loss and noise are caused. The rotating speed of the fan is 150-3000 r/min. The flow rate is 0.15-1200 cubic meters per minute, the pressure is 9.8-196 kilopascals, the power is 0.75-1000 kilowatts, and the weight of a single machine is 100-9000 kilograms.

In order to improve the air outlet flow and pressure and meet higher requirements on a high-pressure fan, the diameter and the rotating speed of the blades are increased, the high-pressure fan is successively developed to a single-section impeller, a double-section impeller and a three-section impeller, the maximum pressure of the high-pressure fan is refreshed to 230 kilopascals once, the weight and the manufacturing process difficulty are increased, and the efficiency is reduced.
