Three Tips for Using Fans

We usually use the city gas compression and gas transportation machinery as fans. Fans include fans, blowers, wind turbines, etc. These machines, which are collectively referred to as fans, are all in need of maintenance. Let's share some of the fan knowledge below. <br> Caution 1 <br> fan, fan bearing temperature ≤70 deg.] C was normal, if once raised to 70 ℃, it should be electronically controlled (be) alarm. In this case, you should find out the reason why the cooling water is normal and whether the bearing oil level is normal.

2. During the process of driving, parking or running the fan, if abnormal phenomena are found, it shall be checked immediately.

3. After the fan has been operated for the first time for one month, it should be renewed to replace the oil (fat).

Common faults The fan working medium in the cement industry often contains a certain amount of same-sized particles of different sizes and shapes, such as the induced draft fan of the dust removal system and the blower for pneumatic conveying. Because these fans work in a dust-laden air stream, the dust particles in the air stream must not only cause wear to the fan, but also deposit dust on the fan blades, and the wear and dust accumulation are not uniform. As a result, the balance of the rotor of the fan is damaged, causing vibration of the fan and shortening the life of the fan. In severe cases, the fan may not work properly. In particular, the wear of the fan blades is the most serious. It not only destroys the flow characteristics in the fan, but also easily causes major accidents such as blade breakage and flying.

The wear of the transmission parts is also a common problem for fans, including various shafts, rollers, speed reducers, motors, pumps and other bearing positions, bearing seats, keyways, and threads. The traditional welding machine processing methods can easily cause materials. Damage, resulting in component deformation or fracture, has greater limitations; brush plating and spray remachining methods often require external association, not only a long repair period, high cost, but also because of the repair material or metal material, can not be fundamentally Solve the causes of wear (metal impact resistance and poor concession); many parts can only be replaced by scrap, greatly increased production costs and spare parts inventory, so that the company's good resource advantages have been idle and wasted.
