Special gas roots blower
Generally, the conveying medium of Roots blower is air, but when the conveying medium is special gas such as natural gas, gas and biogas, special sealing should be carried out. Roots Blower Factory advantages: General seal is mechanical seal. But we have a new approach – piston ring seal. The gas reaches zero leakage, and the safety is higher. High efficiency, energy saving and stable operation, the fan processes fine imported bearings, belts and other accessories.
Special gas roots blower features:
1. Fan castings are first rough machined, and then the second coarse and fine processing, after the product testing is completed. The casting has excellent quality and stable performance.
2. The impeller adopts advanced compound profile and is processed by precise CNC machine tool. After the impeller is assembled, the clearance is uniform and the volumetric efficiency is greatly improved.
3. The world’s advanced structural design schemes such as special inlet and exhaust port and internal reflux are adopted to slow down the backflow impact of high-pressure gas and effectively reduce the fan noise.
4. Splash lubrication is adopted in both main and auxiliary oil tanks, and the lubrication of gears and bearings is safer and more reliable.
5. The bearing is made in Japan and the belt is imported from America.
6. It is made of 20CrMnTi material. The precision is up to GB / t10095 (two precision grades higher than the national standard grade 7). The hardness of tooth surface and taper hole reaches hrc56-62 after carburizing and quenching.
7. The sealing structure has been optimized to ensure that there is no oil contamination in the conveying gas.
Notes for Roots blower as special gas:
1. If it is found that roots blower has abnormal sound, serious motor heating, shell charged, switch tripping, unable to start and other phenomena during operation, stop the machine immediately for inspection. In order to ensure safety, it is strictly prohibited to carry out maintenance in Roots blower operation. After maintenance, the test run should be carried out for about five minutes, and the machine can be started again after confirming that there is no abnormal phenomenon.
2. Roots blower can operate under complete normal condition. Ensure sufficient capacity of power supply facilities and stable voltage, and it is strictly prohibited to operate without phase. In addition, the power supply lines must be dedicated lines, and temporary lines should not be used for long-term power supply.
3. The use environment of Roots blower should be kept clean, the fan should be cleaned regularly, the dust and other impurities in the fan and pipe should be removed regularly, and the fan surface should be clean and the air inlet and outlet should be unblocked.
4. According to the operating environmental conditions of Roots blower, the lubricating grease of bearing should be supplemented or replaced from time to time (the motor closed bearing does not need to be replaced within the service life). In order to ensure the good lubrication of Roots blower in the operation process, the oil filling frequency shall not be less than 1000 hours / time. The bearing and motor bearing shall be sealed, and 2 / 3 of the inner and outer rings of the bearing shall be filled with lithium based lubricating grease. It is strictly forbidden to run without oil.
5. Roots blower should be stored in a dry environment to avoid moisture on the motor. When roots blower is stored in the open air, rain proof measures shall be taken. In the process of storage and handling, the fan should be prevented from collision to avoid damage to the fan. In addition, there are many precautions, such as gas booster fan daily refueling, fan pressure inspection and so on. It’s almost enough to do the maintenance well.
Roots blower for special gas is mainly used to transport acetylene in PVA industry, which can meet the requirements of transportation of inflammable and explosive special working conditions. It has good economic and social benefits and broad market prospects. If you need special gas roots blower now, you can contact us at any time!
