Kun celebration card total ordinary blower vacuum-pressure line-intensive transition back five series, hundreds of varieties, widely used in sewage treatment pneumatic conveying of aquaculture food processing power metallurgy cement mining and other fields, sales outlets all over the country, and improve sales and service network to provide customers with better quality and efficient service blower KQSR Features: 1, resin sand casting process, quality fully guaranteed. 2, in strict accordance with involute impeller design theory, and in the computer simulation done long ago installed balancing test, and fully guarantee the involute meshing characteristics, effectively reducing the leakage and improve efficiency. 3, cabinet, wall by high-precision digital coordinate boring machining, high precision, stable quality. 4, the intake and exhaust ports spiral structure and to install a muffler, intake and exhaust pulsation so gentle, small vibration, low noise. 5, lubrication lubrication according to the situation using the main fuel tank, not only more reliable lubrication and solve many of the shortcomings greased and effectively improve the bearing life. 6, sealing structure is reasonable, oil and gas can not enter the cabinet, clean gas output, excluding oil and gas. 7, bearings, belt imported, bearing man this bearings, belts for US manufacturing. 8, fan gear used 20CrMnTi carburizing treatment, grinding, precision up to five, the tooth surface more resistant, can significantly reduce gear noise. 9, Kun Hing blower factory have been a 48-hour test run, debug qualified to be shipped to ensure the quality of the fan before leaving the factory. First, the working principle of clover Roots blower clover Roots blower works: in the cavity configuration of two clover-type rotors on both sides of the cavity in the open have suction and discharge ports, through a pair of synchronized gears the role of the two rotors turning in opposite directions and do rely on the work of two intermeshing rotors, so that inlet and outlet relative isolation, the passage of the gas chamber to achieve the purpose of the blast. Second, the installation requirements of a Roots blower, the foundation should be strong, the surface should be smooth, and to higher ground 10-25㎝. 2, surrounded by fans to leave enough space to meet the needs of maintenance and removal. 3, the fan operating ambient temperature must not exceed 40 degrees Celsius, such as more than, to take measures to cool down, otherwise shorten the life of the fan. 4, when the outdoor fan configuration, set the anti-canopy. Third, the requirement of a Roots blower duct, fan duct should be connected tightly, not leak, the stent disposed at an appropriate position. 2, the pipe material should be able to withstand the exhaust gas temperature and pressure. (As used in the steel) 3, internal piping must be clean, free of foreign material, to prevent debris from entering. 4. To install the pipe check valve to prevent backflow pressure gas caused due to the reversal fan into the fan, resulting in the destruction of the fan. Note: The one-way valve to be installed in horizontal pipelines. 5, multi-tied wind turbine operation occasions trail must be set each gate charge (including when a wind turbine overhaul, can cut the pipe). 6, shall be provided on the pipe emptying valve to prevent the fan belt load starting, idling the fan should start and then gradually close the drain valve. With a load operation, shutdown, it should open the drain valve after confirming the fan without load, then shut down the fan. IV Notes prior to start a Roots blower, check the anchor bolts and other connections are secure. 2, remove the pipe welding slag and other foreign matter. 3, the valve to be placed in the fully open state, otherwise the fan overloaded, damaged fan. 4, check, add gear oil. At the factory, the tank has been filling gear oil, check the gearbox oil level. In shutdown, the center added to the oil window, but do not want to add, otherwise it will lead to oil spills. 5, bearing butter filling. Fan normal operation, depending on the actual working conditions raise once or twice a week. 6. Check the narrow V-belt tension and pulleys prejudiced. Pulley alignment ruler prejudiced available. Belt tension adjustment can refer to the table below. After a period of time, the belt will become loose, this time to re-adjust. 7. Check whether the power supply voltage and frequency on the motor nameplate parameters. 8. Check the steering pulley. Faced pulley observed to be consistent with the rotating pulley turn arrow signs. 9. Turn the pulley by hand before starting, without exception, to start the fan. Fifth, a job description, initial operation due to the viscosity of the lubricant may appear excessive noise and current phenomenon, to be run can disappear after 10-20 minutes. 2, adjust the gas flow rate of gas flow can be increased or decreased by changing the fan speed or adjust the overflow pipe. 3, there are differences in the same type of noise, because the fan in different positions and in the case of mechanical piping interior noise will cause the difference. 4, the fan should work within specification (8) nameplate pressure. Pressure gauge connection Arbors switch and fan duct. Meters for measuring the pressure of steel and copper alloy non-corrosive media. Meter when measuring the amount of steady pressure shall not exceed the upper limit of the instrument measuring 3/4 fluctuating pressure measurements, the instrument must not exceed the upper limit of 2/3 in the use of the instrument must be checked periodically, at least once in March. Instrument suitable for ambient temperature of -40 ℃ to + 60 ℃, relative humidity less than 80% places. Instruments attached at the measurement point and should be online at the same level. When the fan working pressure gauge switch must be in the off state, the instrument will be at the top of ventilation when using a rubber head cut. For measuring the pressure when, before the switch is open, then close it after testing. Drastic changes in order to reduce shock and vibration and impact on the instrument measured media, when used to purchase a buffer structure.
