< rrThe oblique flow fan, also known as the mixed flow fan, is a fan between the axial flow fan and the centrifugal fan. The impeller of the oblique flow fan allows the air to move both centrifugally and axially, and the movement of the air in the shell is mixed. There are two forms of motion, axial flow and centrifugal flow.

< rr material components
< < r r>Commonly used materials for making diagonal flow fans are: steel, fiberglass, aluminum, etc.
< r r>The main components of the diagonal flow fan are: motor, impeller, outer cylinder, inner cylinder, guide vanes, feet, etc.
< r r>Supporting components Huabo diagonal flow fan silencer, effective Solve the noise problem.
< r r
< r> r>Principle
< < r r>Use the meridional acceleration method and quasi-ternary flow theory to design the mixed-flow fan using a conical wheel structure, twisted wing blades, and an air inlet Add a collector or curved muffler.
< r r
< r> r>Advantages
< < rr has high pressure, large air volume, high efficiency, compact structure, low noise, small size, and easy installation.
< r r
< r> r>Scope
< < rr is widely used in ventilation and exhaust, pipe pressurized air supply and other high-end civil buildings such as hotels, restaurants, shopping malls, office buildings, and gymnasiums. Ventilation places in industrial and mining enterprises.
< r r
< r> r>Structural features
< < rrThe diagonal flow fan is mainly composed of an impeller, a casing, an inlet collector, an outlet guide plate, a motor and other components.
< r r>The casing is cylindrical and divided into three flanges to form a whole. The outlet and inlet are connected to the pipe network along the air flow. The inlet air collector is made into a sword-type streamline shape and is equipped with sound-absorbing mesh panels. The overall structure is equipped with a guide plate at the outlet, so that the outlet airflow has good airflow distribution and stable pressure maintenance.

< r> rUses
< < r r>The diagonal flow fan can be used for general ventilation. The usage conditions are as follows:
< r r>. Application location : As indoor ventilation in general factories and buildings, it can be used as both input gas and exhaust gas.
< r r>. Type of gas transported: air and other non-flammable gases, gases that are harmless to the human body and non-corrosive to steel.
< r r>. Impurities in the gas: No viscous substances are allowed in the gas, and the dust and hard particles contained should not be larger than 1.
< r r>. According to the special needs of users, magneto drive can also be designed to achieve infinitely variable speed and variable air volume structures.
< r r>. Gas temperature: no more than .
< r r
< r> r>Performance Selection
< < r r>. Check the performance of the fan according to the performance table. The performance listed in the table is the performance within the highest efficiency range. According to The flow rate is divided into six performance points, and the selection shall be based on the performance table.
< r r. The factory-qualified performance of the fan is that the total pressure value does not exceed % at the rated flow rate.
< r r. The performance selection table is based on the fan performance under standard conditions. Regardless of technical documents or ordering requirements, the performance is based on the standard conditions. The standard conditions include atmospheric pressure B, atmospheric temperature, and relative humidity. status, when the actual use conditions do not meet the above, the conversion shall be carried out according to the relevant formula.
< r r>. Fan installation methods can be divided into vertical and horizontal. If vertical installation must be specified when ordering, if there are special requirements on flow, pressure and other performance parameters, our factory will provide separate instructions for you. Design and production.
