The wallboard of Roots blower is on both sides of the casing. The wallboard is equipped with seals and bearing seats as the support of the blower and is combined with the casing to form a closed cylinder. The wall panels of vertical blowers are of integral structure, the bearing seat and seal are in the same integral structure, and the wall panels of horizontal blowers are of combined structure, that is, the wall panel is divided into upper and lower parts, the lower part is one piece, and the upper part is divided into two pieces, the seal and bearing seat are separated, and the separated part is exposed. For the transportation of corrosive media, if the previous two structures both adopt the same sealing structure, when the sealing performance is poor, the corrosive media will be discharged to the outside instead of directly entering the bearing after leakage. Therefore, the bearing of the latter structure suffers from corrosion damage slowly and has a longer service life compared with the bearing, while the former is damaged quickly and has a shorter service life due to corrosive media entering the bearing directly.
Fan manufacturers have their own fan product samples and catalogs. In fan product samples and catalogues, the performance table of fans at various speeds is usually listed by series and machine number. The performance parameter values in the table are within 90% of the highest efficiency point of the fan, and the values of 6-8 performance points are taken for selection. Roots blower usually lists the performance parameter values of the highest efficiency point of a single type of single unit at a certain speed.
It is very convenient to use the Roots blower performance table to select fans. However, pay attention to check whether the air volume and air pressure under the actual working condition conform to the air intake status in the performance table. If yes, you can directly check the performance table for selection; Otherwise, it is necessary to conduct performance conversion through relevant formulas, and then select the fan according to the converted parameters. If the performance parameters of two or more types of fans meet the selection performance requirements, the fans shall be selected from the aspects of economy and reliability.
Performance 1: Roots blower is equipped with a silencer and a silencing room. The vibration sound of the blower is very small, almost silent, which effectively reduces the noise pollution and brings convenience to the production of enterprises.
Performance 2: The impeller and shaft of Roots blower are of integral structure, and the impeller is free of wear, so that the working performance of the blower remains stable, the working performance remains unchanged, and it can operate well for a long time, with a longer service life.
Performance 3. Roots blower is equipped with a high-quality motor, with a temperature resistance rating of 180 degrees. The motor silicon steel sheet is made of high-grade cold rolled steel, with excellent quality, stable performance and more powerful power.
Performance 4. Roots blower is easy to install, and the installation mode is flexible. The volume utilization rate of the fan is large, the volume efficiency is very high, and the structure of the fan is also very compact. Therefore, it is convenient and fast to install, and saves a lot of manpower, material resources and financial resources for enterprises. Work efficiency has also been constantly improved.
Performance 5. Roots blower is easy to clean and maintain. As long as the oil tank of Roots blower is cleaned regularly, it is recommended to replace all lubricating oil after 8 hours of operation. It is better to overhaul the fan once a year for a full body inspection. To ensure the good operation of Roots blower.
I believe that after reading the above, you should also know how to select Roots blower according to its performance. I hope it will be helpful to you.
