Rotary fan with a pre-prepared, rotary fan should be installed horizontally. 2, the fan room should be left rotary blower vents and install ventilation fans use to be located in the upper and lower two vents to facilitate air convection rotary fan to prevent overheating inside the room affect the normal operation of the rotary fan. 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 five observed dripping out of the mouth of inorganic droplets (11-13 drops / min), and see if there is a transparent flow of oil return pipe. 6, rotary blower before you start winning air intake filters, to pour about 40ml of oil within the host, so that the oil evenly distributed in the interior rotary fan HCC-20S vertical rotary fan flow Qs refers to standard suction state (absolute pressure 101.325kPa, temperature 20 ℃, relative humidity 50%), the medium is the air inlet flow rotary blowers, for the non-standard state flow segment for conversion. HCC-20S vertical rotary fan flow conversion: When the inlet flow rate with the reference state (temperature 0 ℃ rotary fan wholesale phone, absolute pressure 101.325kPa) volume Qn is represented, you must first be converted to the press under the standard suction state After the traffic rotary blower manufacturer 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 is 29, the actual intake air flow rate Qs is calculated as follows: Qb = (Qth-Qsa) × [(273 + ts) / (273 + 20) × 29 / M] 1/2 where: Qb- suction gas temperature ts ℃, the molecular weight of internal leakage when M m3 / min; Qth- theoretical flow m3 / min; ( According to the requirements of the boost declining chip fan inlet flow rate, 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) performance parameters listed in the air as the medium, such as transportation or other media with the standard intake state does not match state into gas flow required to make the appropriate conversion.
