  Roots blower in the application of the gas transmission

  By installing the roots blower in the previous gas pressure sensors on the measured stress signal, control the output frequency of frequency converter, makes the speed of the motor changes with the change of the gas collector pressure. Because the shaft power and speed of the direct, and the output of the active power is cubic drops, so greatly reduce the energy consumption of the motor, and enhance the automation of the gas transmission link. Converter can be automatically (that is, through the pressure signal to adjust output frequency) and manual (set by artificial work frequency) work under the two states, and have auto voltage reducing start with inverter start function on each other, when one of them works in the maintenance or failure, can be manually switch to a different kind of way of working, and will not affect the normal production. Fan type silencer of choose and buy, the user should submit the fan type (blower, roots blower fan, and axial flow blower, air compressor, etc.), and provide the fan size and volume of imports and exports, general fan muffler are installed in exports, fan noise elimination should be comprehensive, the muffler and sound insulation room colleague installation. Outer shell fan muffler for carbon steel, aluminum and stainless steel inner material cent two kinds of, the user can be selected according to the cost condition. Boiler steam discharge type silencer of choose and buy, the user should provide an hour of emissions, exhaust outlet size, exhaust temperature and pressure. Exhaust muffler is generally resistant spray impedance compound muffler of choose and buy, general outer shell of the muffler for carbon steel, takeover and internal material is stainless steel, with a dead band width, use range, large amount of noise elimination and resistance to high temperature and high pressure, not afraid of water vapor and oil mist, etc. Also can use small hole injection type muffler, generally for all stainless steel manufacturing. Constitute the inlet chamber and exhaust cavity isolated from each other, with the aid of two rotor reverse rotation, gas in the body by the air intake cavity exhaust to the cavity, reach the role of blast. Because between the impeller, the impeller and casing, impeller and panels are very small in clearance, so the runtime don't need to note in the cylinder lubricant, also do not need to oil and gas separator auxiliary equipment. Because there is no mechanical friction between the rotor and thus has high mechanical efficiency, overall produce less heat, long life and other advantages. Roots blower is more sophisticated equipment, maintenance at ordinary times should pay attention to the inlet filter cleaning and replacement of indoor air clean and smooth, lubrication to guarantee.

  How to reduce the noise source and the control method

  Installed muffler because under normal circumstances, the radiation from the fan air inlet and outlet air dynamic noise is higher than from other parts of the radiation noise of 10 ~ 20 db (A) [4], therefore, to control the fan noise, first of all should be installed on the intake and exhaust path appropriate muffler, the muffler is used on fan, both at home and abroad tend to adopt impedance muffler, sound channel, and large volume, narrow muffler has been rarely used, of course, muffler selection, design and installation shall be carried out according to the actual situation. Fan during normal operation, with the wear and tear, and 45 ° gap position will change accordingly, including + 45 ° gap tends to decrease, while the 45 ° position gap tends to increase. Roots blower when normal wear to a certain extent, under the good maintenance, should be in commonly run continuously 7 ~ 8 years), two impeller will encounter, and the first collision of parts in the position of + 45 °. Thus, working in the adjustment of two impeller clearance, should advance the + 45 ° the appropriate position of the gap is big, generally to - 45 ° location 2 times (assuming a gap for a 45 °, the + 45 ° for 2 a). Another approach is to 45 ° position directly to a gap to 0.4 ~ 0.5 mm or less (45 ° - when the gap has certain influence to the air volume, clearance volume is reduced). After set, and the original position stagger, hinge positioning pin hole. The impeller and the space between the left and right wall plate, can increase or decrease in 313 bearing end cover gasket to adjust. Relative to centrifugal and axial flow fan, because the change of the structure itself multi-function mixer in drop sucking type self-cleaning filter a lot of reports have low noise, and achieved results, but reports about bo's fan is rare, therefore, roots blower is to make some studies on the basic way to reduce noise, improve net lotion roots blower pneumatic inside the chassis and the structure design, using impeller circumferential surface wind, twisting the foliage, the 2 under instead of three leaves roots blower impeller, correct installation, maintain a reasonable run.

  - three leaves roots blowers zhangqiu yi tai machinery manufacturing co., LTD. Is a professional manufacturer of roots blower ZLSR company. Its main products are roots blower, roots blower, and three leaves roots blowers three-blade roots blower, high pressure blower, ZLSR, three leaves roots blowers ZLSR fan is my company to design, development, production of a highly efficient, energy saving, environmental protection and new products. This wind turbine parts adopt numerical control machining center for processing, and has advanced detection equipment and high-quality personnel, to ensure that each factory equipment and have high quality, high service life. The company to provide you with perfect pre-sales consulting and after-sale tracking service, for every customer to remove trouble back at home, the new and old customers get the praise. My company is located in the east of jinan MingShui, jinan-qingdao road north, 18 kilometers away from jiqing expressway, jiaoji railway traverses MingShui city, traffic is very convenient. Welcome all customers to visit my company guidance, business negotiations. Telephone: 13705411652
