Roots blowers may encounter some issues during operation. Today, the Mingfeng fan manufacturer will share with everyone the reasons for the high temperature of the fan.
When working, Roots blowers may encounter some issues. Today, the Mingfeng fan manufacturer will share with you the reasons for the high temperature of the fan.
Generally, the heating of the Roots blower refers to the high temperature of the entire casing caused by excessive exhaust temperature, as well as the high temperature of the oil tank caused by high bearing temperature and high lubricating oil temperature.
The main factors affecting the outlet temperature of the fan include: fan volumetric efficiency, working pressure, internal leakage of the fan, and intake temperature, etc. High temperature is an abnormal phenomenon that can bring many adverse effects to the fan itself, even leading to shutdown, which in turn affects the operation of the entire system. You can understand the following five points:
Too much and too concentrated oil in the fan oil tank, excessive oil quantity, and serious pollution;
2) The fan filter or fan silencer is blocked;
3. The operating pressure of the fan is higher than the value specified on the nameplate;
(4) Excessive wear of the fan impeller leads to an excessively large gap in the fan impeller;
(5) Poor ventilation in the air chamber, high temperature in the machine room, leading to high temperature at the air chamber inlet;
How to avoid high fan temperature can be approached from the following points:
First, the pipeline. Pipeline pressure is a relatively easy factor to cause high fan temperature. Depending on the diameter of the Roots blower, the diameter of the outlet main pipe is fixed. If the pipe diameter is artificially changed according to special requirements, it can easily cause pressure loss. In agricultural production, the fineness of the main pipe often appears. To change the fineness of the main pipe, corresponding treatment is required to ensure the normal discharge of the fan.
Second, the working environment. The fan operates in the pump room according to normal design standards, but in practice, most Roots blowers operate in outdoor environments. In summer, the impact of environmental factors is more pronounced. In conditioned places, cooling equipment can be configured to minimize the impact of environmental factors on the fan, or soundproof covers can be used along with heat dissipation devices.
3. Fan configuration. The pressure of the fan is related to the air volume, but small fans often carry large fans. In this way, the fan will impose a greater load on the motor to meet the flow requirements during use, leading to motor overheating and fan overheating.
4. Fan installation. If the flow pressure is normal when the new fan starts to use, but the overload is not thermal, but after a period of time, it starts to burn, the fan needs to recheck the tightness of the belt and re-tighten the screws.
The above introduction is about the relevant knowledge of high temperature in Roots blowers. I hope everyone can gain some understanding after reading.
