Function Chapter 丘瑞泰罗茨 blower, clover Roots blower, Roots blower, clover Roots blower, Roots blower maintenance, Roots blower parameters, Roots blower works air blower device works is itself The mechanical energy transmitted to the air. The air pressure difference and flow in the pipeline, to provide the power source for the pneumatic ash handling system. Pneumatic ash handling systems for gas supply equipment with special requirements, such as high efficiency, wind, air pressure to meet the requirements for the transportation of materials, the impact of air flow when air pressure changes should be small, and so on. Gas-fired power plant ash handling system, air supply equipment commonly used air compressors, blowers (such as centrifugal, Roots and water ring vacuum pump. Blower points both horizontal and vertical. Horizontal Roots Blower It consists of two involute waisted rotor (hollow or solid), oblong cabinet, composed of two parallel shafts. cabinet can be divided with water cooling, air cooling and no cooling device categories. actuator is At the same ends of the two shafts provided with the same style and size, and the two gears meshing with each other, so that the driving shaft is directly connected to the motor, and driven by the driven gear for the reverse direction of the rotation axis. Each revolution of the rotor can be pushed out of the double shadow volume of air, thus rotating the drive shaft each week pushed out four times the shadow volume of air blower inlet and outlet should be a reasonable arrangement: the lower end of the upper exhaust inlet (for horizontal and words), so you can take advantage of the high-pressure gas to offset gravity portion of the rotor shaft, reducing the bearing pressure and reduce friction. theoretical wind Roots blower is qvt = 4Aonl, where A. is in vertical position of the rotor and the casing inner wall area surrounded approximated calculation of which is equal to the area of ??movement of the rotor depicted πD2 / 4 of 1/3, A0 = l / 3xπD2 / 4 = πD2 / 12. Thus, the results of the theoretical amount of wind qvt = 4x (πD2nl) / 12 = 1 / 3πD2nl. As the rotor and turn in between, there is a gap between the rotor and the housing exists, the air will leak back to the suction side, so that the actual amount of gas less than the theoretical amount of wind that qv = ηvqvt = πD3nlηv D-- . waisted rotor diameter that is between rotor two vertex distance, m; L-- waisted rotor length, m; n-- rotor revolutions .rpm; ηv-- volumetric efficiency, general ηv = 0.75-0.85 From the theoretical analysis shows that, as long as the motor can be driven blower can work under any pressure, however, as the outlet and inlet pressure difference is too large, there will be a lot of air leakage through the gap back to the inlet, resulting in lower fan efficiency.; Meanwhile, the speed is too high, it may cause vibration and shorten the life of the machine, so the outlet pressure is not too high. Domestic Roots blower static pressure between 19620 ~ 207910Pa, air volume 0.25-250m3 / min (standard state below), there are 580,730,960 and the general speed of 1450rpm take the blower inlet and outlet sections, lists containing blower mechanical energy equation, we can draw energy out L:. L = ∫21 formulas, thermodynamic processes and gas-related Since the blower inside the adiabatic compression of gas, the energy of the blower head L. lJ compressed gas consumption of so-called Zhuo where: - breathing space, absolute pressure, h; / I-- fan static pressure at the outlet of the gas, . h; isentropic index c-- gas in the total pressure, the dynamic pressure proportion of small, can ignore represents the effective power to kill household fan pressure, the blower fan for the wind g\-- unloading - - static pressure feng machine shaft power blower 9 is where the overall efficiency of a wide blower (adiabatic efficiency), general 1. Advantages 1) Under normal circumstances, the impact speed is proportional to the pressure change is small, fan air volume, thus Roots blower basically constant volume; 2) no pulsation suction and exhaust is not necessary buffer tank; small 3) footprint, easy layout and installation; 4) between the rotor and the hands, the rotor and housing 0.2-0.5mm gap between reservations, there is no friction phenomenon that allows a gas stream containing some dust; 5) Compared with the water jet pump and water ring vacuum pump, not "exhaust with water" problems; 6) reliable , easy maintenance, durable. 2. The defect 1) noise, import and export needs muffler installed; 2) in a high vacuum conditions, leakage increased blade clearance, the transport decline, could easily lead to plugging. Clover Roots blower on the fan, duct What features clover roots blower is a dual impeller synchronous compression machinery, every cloverleaf with two spherical roller rotor bearing, hardened steel with a pair of synchronized gear, so that the relative position of the two rotors remain unchanged. It belongs to positive displacement blowers, a mandatory gas transmission characteristics, flow stability. Reflux resonant cavity structure, low noise. Clover Roots blower fan installation requirements 1, the foundation should be strong, the surface should be smooth, and above the floor 10-25㎝. 2, around the fan to leave enough space to meet the needs overhaul and disassembly. 3, the fan operating temperature must not exceed 40 degrees Celsius, such as when exceeded, to take measures to cool down, or shorten the life of the fan. 4, outdoor fan configuration, set the anti-canopy. Clover Roots blower pipe to claim 1, the fan duct should be connected tightly, not leak, set the bracket in place. 2, the piping material should be able to withstand exhaust temperatures and pressures. (Try to use pipe) 3, the inner tube to clean, no foreign body, to prevent debris from entering. 4. To install the pipeline check valve to prevent backflow of gas due to the high pressure caused by the fan into the fan reversal, resulting in the destruction of the fan. Note: The check valve to be installed in horizontal pipelines. 5, parallel operation of multiple wind turbines occasions, each in charge of track must be set gate (where when a wind turbine overhaul, the pipe can be cut-off). 6, shall be provided on the pipe emptying valve to prevent the fan with a load start, the fan should load starting and then gradually close the drain valve. With a load operation, shutdown, it should first open the drain valve confirmed fan without load, then shut down the fan. Lobe Roots Blower widely used in ceramics, building materials, paper, electricity, petroleum, chemical, textile, aquaculture, waste water treatment, food and other industries pneumatic conveying system for conveying air and a variety of neutral gas. But not to the transportation of flammable, explosive, toxic and corrosive gases. Product processing high accuracy, good performance, reliable operation, long life, simple structure, maintenance, and maintenance. Including attachments, fans standardization body, a sound production system, at any time to meet your requirements. The fan is running on the 80kPa boost range without cooling water.
