Roots blowers are a sewage treatment plant biochemical reactions during oxygen transfer aeration blower basic equipment. The device is suitable for all sizes of urban sewage treatment plant grit process applications, also suitable for small urban sewage treatment plant biochemical reaction process aeration. This paper Roots blower in sewage treatment principle, usage and basic maintenance method analysis. Biological contact oxidation process, aerobic microorganisms during the oxidative decomposition of organic matter consumes dissolved oxygen, and therefore need to replenish oxygen in wastewater. Microporous aeration, oxygen transfer rate of 25% -32%. Roots blower system belong to the volume rotation blowers, sewage treatment plant biochemical reactions during oxygen transfer aeration blower basic equipment. Its biggest feature is the use when the pressure within the allowable range to adjust the flow of little change, the pressure is very wide range of options, a mandatory gas transmission characteristics. When the transmission medium is not oil. Simple structure, easy maintenance, long service life, machine vibration. Roots blower transport medium for the clean air, clean kerosene, sulfur dioxide and other inert gases, in view of the foregoing character, which can be widely used in various scale municipal sewage treatment plant processes in aerated grit and small urban sewage treatment plant biochemistry aeration reaction process. Product Overview: Now blower market prices Roots blower, Roots blower varying quality, Roots blower model number, how to buy blower? Roots blower manufacturers now introduced Kun Zhucheng celebrate machinery, the company is specialized in the production of Roots blower Roots blower, clover Roots blower business. The company is strong in technology, technology-equipped, the large CNC machine tools (such as CNC planer, boring) manufacturing inspection, I plant blower model is complete, the main features of clover Roots blower: create sophisticated, low noise, high efficiency, Roots blower price. Mainly used for environmental protection, gas transportation, waste water treatment, aquaculture, pneumatic conveying, cement, chemical, steel and other industries. Our strengths: quality and stability: the whole process of quality control, reasonable price nuanced: efficient internal cost control and reduce costs, to help customers convenient delivery: advanced assembly line, redo the inventory and shorten the delivery service: attention to detail after-sales service system, allowing you to buy rest assured Features: Roots blower KQSR advantages: 1, casting resin sand process, quality fully guaranteed. 2, in strict accordance with involute impeller design theory, and on computer simulations done long ago installed balancing test, and fully guarantee the involute meshing characteristics, effectively reducing the leakage and improve efficiency. 3, cabinet, wall panels from the high-precision digital coordinates boring machine processing, high precision, quality and stability. 4, the intake and exhaust ports spiral structure, the intake and exhaust pulsation gentle vibration and low noise. 5, lubrication lubrication according to the situation using the main fuel tanks, not only more reliable lubrication and solves many of the shortcomings greased effectively improve the bearing life. 6, the sealing structure is reasonable, oil and gas can not enter the cabinet, gas cleaning output, excluding oil and gas. 7, bearings, V-belt imported, bearing man this bearings, belts for American manufacturing. 8, fan gear used 20CrMnTi by carburizing, grinding, precision up to five, the tooth surface more wear, can significantly reduce gear noise. 9, Kun celebrate blower factory have been a 48-hour test run, commissioning qualified to be shipped to ensure the quality of the fan before leaving the factory. Product main parameters: KQSR blower fan diameter: 65mm Pressure: 9.8kpa-98.8kpa air volume: 1.9 m3 / min Motor power: 2.2kw Standard configuration: Common base, belt cover, fan pulleys, pressure relief valve, pressure gauge, anchor bolts. Instructions: First, the working principle of clover Roots blower clover Roots blower works: in the cavity configuration of two clover-type rotor on both sides of the cavity opening a suction port and the discharge port, through a the role of synchronous gears, so that the two rotors turning in opposite directions and do rely on the work of the two rotors mesh with each other, so that the suction inlet and outlet cut off from the passage of the gas chamber to achieve the purpose of the blast. Second, the installation requirements of a Roots blower, 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. Third, the requirement of a blower duct, 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. Fourth, note before the blower start 1. Check 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, or fan overload, damaged fan. 4, check, add gear oil. The factory has been filling the tank gear oil, check the gearbox oil level. In shutdown state, added to the oil window center, but do not want to add, this will cause oil spills. 5, bearing butter filling. Fan normal operation, depending on the actual working conditions raise 1-2 times a week. 6. Check narrow V-belt tension and pulleys prejudiced. Pulley alignment ruler prejudiced available. The belt tension can be adjusted following table. After a period of time, the belt will become loose, this time to readjust. 7. Check whether the supply voltage and frequency parameter name brand motor. 8. Check the steering pulley. Faced with the pulley observed to be consistent with the rotating pulley turn arrow signs. 9, before the start of the hand rotating pulley, without exception, to start the fan. Five job descriptions blower 1, the initial run because the lubricating oil viscosity, 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, the same type of noise are different, because the fan in different positions and in the case of the piping can cause differences in the machine room noise. 4, the fan should be operated within the specification nameplate pressure. Pressure gauge connected via the coupling lever switch and the 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 3/4 meter measurement, pressure measurement fluctuations, the instrument must not exceed the upper limit of two-thirds 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% of places. Instrumentation and measurement at the attachment points should be online at the same level. When the fan is working, pressure gauge switch to in the off state, the instrument will be at the top of ventilation when using a rubber head cut. For measuring pressure when, before the switch is turned on, after measuring and then close it. Dramatic changes to reduce shock and vibration and measured medium influence on the instrument, acquire a buffer structure use.
