HCC-20S vertical rotary fan flow Qs refers to standard suction state (absolute pressure 101.325kPa, temperature 20 ℃, relative humidity of 50%), the medium is the air inlet flow rotary blowers, and for non-standard state of the traffic section for conversion. HCC-20S vertical rotary fan flow conversion: When the intake air flow rate with the reference state (temperature 0 ℃, absolute pressure 101.325kPa) volume Qn represents when the rotary fan use, you must first be converted to the press under the standard suction state After the flow Qs, and then check the performance table (usually not considered humidity). Qs = 1.0733Qn ts when the intake air temperature and 20 ℃ difference between the larger, or inhalation of the gas molecular weight M deviate significantly from the molecular weight of air 29, the actual intake air flow rate Qs calculated: Qb = (Qth-Qsa) × [(273 + ts) / (273 + 20) × 29 / M] 1/2 where: Qb- suction gas temperature ts ℃ rotating fan, a molecular weight of internal leakage when M m3 / min; Qth- theoretical flow m3 / min ; (upon request boost declining chip fan inlet flow rotary fan supply prices, according to the performance table after the initial selection by the performance table Richard). Actual m3 Qsa- standard suction state / min flow rate. (Flow performance shown in the table after the initial selection) listed performance parameters with air as the medium rotating turbine prices, such as transport or other media with the standard intake state does not match state into the gas flow required to make the appropriate conversion. Rotary fan with preparation 1, rotary fan should be installed horizontally. 2, the fan room should be left vent and install ventilation fans, vents easy to set up and down two air convection to prevent the engine room temperature is too high impact rotary fan running. 3, the inner wall surrounding the engine room is preferably provided with sound deadening material to reduce noise. 4. Correctly connect the distribution lines and attention turned to the rotary blower motor rotation direction markings on the rotating fan effect. Eccentric loading when the rotor rotates in the cylinder body. The turning turbine rotor blade slot 4 reciprocate. The air is sucked into the compression discharge. Constitutes fan blades and rotor, the cylinder block mutual friction generates heat. So the fan operation, the drip mouth dropped to the cylinder block necessary lubricants, lubricating surface to reduce friction heat and friction noise; and part is formed between the layer of film fans to keep rotating seal.
