< rr r> < rr rr r> < rr < The rr series of oblique flow fans applies the oblique flow meridional acceleration design method and adopts a drum-shaped or straight air duct, a tapered hub, and a twisted airfoil blade structure. It has the characteristics of high pressure coefficient of centrifugal fan and large flow coefficient of axial flow fan. It has the advantages of low noise, low power consumption, compact structure, etc. It can be installed horizontally or vertically. It is widely used in air supply and exhaust systems of industrial and civil buildings. < rr can be made into anti-corrosion and explosion-proof types according to the requirements of the transmission medium, and is used to transport corrosive, flammable and explosive gases. The 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. The movement of the air in the shell mixes both axial flow and centrifugal flow. a form of exercise. Material components Commonly used materials for making diagonal flow fans are: steel, fiberglass, aluminum, etc. The main components of the diagonal flow fan are: motor, impeller, outer cylinder, inner cylinder, guide vanes, feet, etc. The supporting component Huabo diagonal flow fan silencer can effectively solve the noise problem. Principle: The meridional acceleration method and quasi-ternary flow theory are used to design the mixed-flow fan using a conical wheel structure, twisted airfoil blades, and a collector or arc silencer at the air inlet. The advantages include high pressure, large air volume, high efficiency, compact structure, low noise, small size, and easy installation. It is widely used in ventilation and exhaust of high-end civil buildings such as hotels, restaurants, shopping malls, office buildings, and gymnasiums, as well as pressurized air supply in pipelines and ventilation places in industrial and mining enterprises. Structural features: The diagonal flow fan is mainly composed of impeller, casing, inlet collector, outlet guide vane, motor and other components. The casing adopts a cylindrical shape and is connected by flanges in three sections 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 an overall structure composed of sound-absorbing mesh panels. The outlet is equipped with a guide The flow sheet enables the outlet airflow to have good airflow distribution and stable pressure maintenance. Purpose: The diagonal flow fan can be used for general ventilation. The usage conditions are as follows: . Application: As indoor ventilation in general factories and buildings, it can be used as both input gas and exhaust gas. . Type of gas transported: air and other non-flammable gases, gases that are harmless to the human body and non-corrosive to steel. . 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. . According to the special needs of users, magnetic motor transmission can also be designed to achieve infinitely variable speed and variable air volume structures. . Gas temperature: no more than . Performance selection. 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. It is divided into six performance points according to the flow rate. The performance table shall prevail when selecting. . The factory-qualified performance of the fan is that the total pressure value does not exceed % at rated flow rate. . 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 are atmospheric pressure B, atmospheric temperature, and relative humidity % degrees. When the actual use conditions are different from If the above does not meet the requirements, the conversion will be carried out according to the relevant formula. . The installation methods of the fan can be divided into vertical and horizontal. If the vertical installation is required, please specify it when ordering. If there are special requirements on flow, pressure and other performance parameters, our factory will design and produce it separately for you. Installation and use []. When installing the fan, a comprehensive inspection of all components should be carried out to see if the parts are complete and whether the connections of each component are tight. . When installing the fan, attention should be paid to maintaining the horizontal position of the fan. The joint surface between the fan and the foundation and the connection of the air outlet pipe should be adjusted to make it natural. There should be no forced connection. The weight of the pipe is not allowed to be added to the parts of the fan. , and check whether there are tools and other objects left inside the fan. . After the fan is installed, the impeller must be moved to check whether the impeller rubs against the casing. If any problem is found, it must be adjusted. The fan must be protected from rain when used in the open air. . The test operation of the fan should be carried out after the overall inspection has passed. In order to prevent the motor from overloading, the flow regulating valve should be closed before starting the fan so that there is no load at startup, and then the valve should be gradually opened to operate at full load or at the design operating point. . If the fan is found to have severe vibration, impact or other abnormal phenomena while it is running, it must be stopped immediately for inspection. . If it is found that the working condition point is offset and the motor is overloaded, in order to prevent the motor from being overloaded, the flow regulating valve can be closed so that the motor is within the rated current. . Regularly remove dust, dirt and other impurities inside the fan to prevent rust.
