According to the following environmental conditions from time to time to supplement or replace the bearing grease (motor enclosed bearing service life without replacing the grease), to ensure that the fan is running in good lubrication, refueling times less than 1000 hours / times closed bearings and motor bearings, fuel zl-3 with lithium grease fill the bearing inner and outer rings of 2/3. Do run short of oil. Fans should be stored ytbz square wall axial fan in a dry environment, avoiding motor damp. Fans at the open storage, proper defensive measures. In the storage and handling process should prevent the fan bump avoid damage induced fan ventilation system with conventional ducted ventilation system compared with the advantages: 1, system design is simple, flexible design changes large, easy to modify, flexible layout, jet direction can be adjusted at any time; 2, easy to install inducing fan, simple construction, Beijing induced fan can be installed in a targeted location induced fan prices, eliminate dead ends. 3. Maintenance fill plus Time: 2012-5-10 induced fan and fan the fire in a mechanical ventilation due to the large difference in temperature and grain temperature, ventilation first time during the day to choose to reduce grain mild temperatures gaps, reducing the occurrence of condensation. After ventilation as much as possible at night FRP square wall axial fans, because this is a cool airy main square wall dfbz axial fans, the evening relatively high atmospheric humidity, low temperature, so that reduces the moisture loss, but also take advantage of the low temperature at night, improved cooling effect. dfbz square wall type axial fans, excellent quality, Wuhu square wall axial fan is provided by air-conditioning Equipment Co., Ltd. Shandong GREAT fan. Air Conditioning Equipment Co., Ltd.
