    High-temperature fire-fighting fans are common ventilator equipment in our daily life. They are used in various industries in our lives. There are parking lots, mining, chemical industries, factories, workshops, and clothing industries. They are countless and must be used. After using the high-temperature fire-fighting fan for a long time, there will also be some failures and problems. For example, the bearing box of the high-temperature fire-fighting fan may have oil leakage. How to remedy it? The following is the Shanghai fan manufacturer-Huihong Fan Xiaobian to introduce you to the high temperature fire fighting fan bearing box oil leakage remedial measures.

    In the long-term use of the high-temperature fire fan bearing box, because the bearing box is tightened with the gland bolt, the gap between the shaft and the filler (oil-soaked asbestos packing) is extremely small, so that the lubricant penetrating here forms a layer naturally. Ring-shaped oil film seal, but the oil thrown off by the oil retaining ring cannot flow back to the oil tank along the oil return ditch, resulting in excess oil permeating outside the main axial box, and at the same time, the running time increases, resulting in packing Severe wear causes the gap between the shaft and the packing to be too large, which greatly reduces the effect of the oil film seal. If the operation is continued in the past, the frequency of oil injection is accelerated, and the fuel consumption is greatly increased, which not only brings economic losses to the user, but in severe cases, the bearing may be damaged or fatigued due to insufficient lubrication due to insufficient lubrication. Severe breakdown accidents caused by transfers and unit shutdown.

    To change the above problems, we can solve the problem by changing the lubrication method of high temperature fire fan bearings.

    One way to change the way the bearings are lubricated is to change the thin oil lubrication to high-quality grease lubrication.

    Another method is to improve the sealing method of the shaft seal structure of high temperature fire fan.

    According to the relative motion relationship between the seal and the sealed part, the sealing method is divided into two forms: static seal and dynamic seal. The fan is a rotating machine, and the seal of the bearing box is a dynamic seal. At present, there are two main types of dynamic seals: the first is a contact seal; the second is a non-contact seal; both have their own scope of application.

    The above is a remedy brought by Shanghai Huihong Fan Xiaobian on oil leakage in the bearing box of high temperature fire fan. I hope it can be helpful to you. Follow our website and get common sense.
