What is the problem with the induced draft fan of the mesh belt dehydrated vegetable dryer?

The machine is continuously working and has been used in many fields. The most important part is the induced draft fan. When we operate, there are often some problems that need to be solved in time so that we can work better. Prevent a series of problems.

Net belt type dehydrated vegetable dryer induced draft fan:

1. The oil pressure of the induced draft fan is reduced. When the oil pressure drop of the draft fan of the dryer occurs, first check whether the oil leaks and the filter is blocked. After doing the leak prevention measures and cleaning the blockage, check whether the fan lubricating oil cooling water is normal. After the input, the oil temperature is normal, etc., after the Zui, check whether the valve status of the dryer air intake system is normal, and check the overflow valve and the lubricating oil pump.

2. The induced draft fan bearing has large vibration. If the induced draft fan has a large vibration during the operation of the dryer, we should check whether the concrete foundation of the production line is firm, and then pay attention to check whether the draft fan blades are worn, ash or collision, and whether the induced draft fan bearing appears. Damage, bending, severe wear, etc. In addition to reasonable maintenance and correction of the above points, it is necessary to strengthen the monitoring of the bearing vibration value, voltage, air volume and other parameters.

3, mesh belt type dehydrated vegetable dryer induction fan bearing temperature is higher. When the temperature of the induced draft fan bearing is high during the operation of the dryer, we need to check whether the induced draft fan bearing wear, insufficient lubrication or bearing vibration, and then check whether the cooling machine works normally. If the above conditions still cannot be restored to normal, check whether the induced draft fan is under overload condition, reduce the load in time, and adjust the operating parameters of the hot blast stove to prevent the flue gas tail temperature from being too high and cause the induced draft fan to malfunction. .
