Air volume is less than 1, 2 filter clogging, a gap increases, replace or clean the filter 2, take appropriate measures to none other sales Roots blower, repair a gap motor overload, filter clogging 2, 3 larger fan boost impeller and impeller, rubbing a wall or cabinet, replace or clean the filter 2, identify the reasons for the boost limit raised to three, repair friction surface. Re-adjust the gap blower motor load how to deal with? First, with a predetermined pressure phase 比罗茨 fans, a large pressure difference, that big high back pressure or inlet pressure blower cheap, reducing the pressure to the specified value; the second point, compared with the flow of equipment required Supply of production of large blower fan too much traffic, so the pressure increases, the excess gas into the atmosphere or lower blower speed; Third, import filter clogging or blockage of the outlet pipe barriers, clearing the entrance foreign body, remove obstructions ; Fourth, rotating parts touching and friction (stuck), finishing; fifth point, the oil level is too high, reduce the oil level; sixth point, narrow V-belt overheating, excessive vibration, pulleys too small, adjust belt. Supply of production of large blower, three cows mechanical (certified), Yunfu blower provided by three cattle Machinery Co., Ltd., Shandong. Machinery Co., Ltd. Shandong three cattle (www.sanniujixie.com) (www.sanniujixie.cn) Shandong Jinan, the other leaders over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In three cattle mechanical leadership with the staff warmly welcome all inquiries negotiations to create three mechanical cow a better future.
