The wind pressure of Roots blower is not limited by the fan speed. No matter how the speed changes, the wind pressure can remain unchanged. The air volume is proportional to the fan speed. With constant torque load, Roots blower's power saving rate is proportional to the speed drop. Although it is different from ordinary fans and pumps, its power saving rate is higher, and as long as the furnace wall is not damaged, it works continuously for 24 hours and has a long starting time, so it has great power saving potential and high power saving costs.
After the technical transformation of Roots blower, the past production method of adjusting the air pressure or air volume by adjusting the opening of the outlet or inlet valve has been changed. The labor intensity is reduced, the timeliness of adjustment is good, the product qualification rate is improved, and the unit consumption is significantly reduced.
Roots blower shall not be installed in places where people often go in and out to prevent injury and scald. When the roots blower is configured outdoors, a rain proof shed should be set up. The roots blower can be used for a long time at an ambient temperature of not more than 40 ℃. When the temperature exceeds 40 ℃, exhaust fans and other cooling measures should be installed to improve the service life of the blower.
Generally, it is very normal if the load is rated, and it is completely abnormal if the load is overloaded. For example, when Roots blower works normally, it is impossible to completely close the valves at the inlet and outlet, let alone overload operation, which is even more inaccurate. Some factories use blowers. If the blowers are used, it is better not to stop suddenly at full load, but to stop after unloading gradually, which can avoid damage to the machine. Due to its characteristics, the gas at the exhaust port is not allowed to return to the air inlet for a long time, which has an impact on the safety of machine oil. In this case, cooling measures should be taken.
Sometimes, you will see the lubricating oil splashing out, so you need to carefully observe the splashing situation and the position of the oil amount. If you find that the oil amount reaches the minimum limit, you should immediately fill the Roots blower with lubricating oil to avoid accidents. If the load is found, it is necessary to adjust the load gradually until it reaches the standard. It is not allowed to adjust the load to the rated load at one time, but can also be controlled by pipes or valves installed nearby.
In fact, when using Roots blower, no matter the position of its inlet or exhaust port, someone should pay attention to it. Once problems are found, they should be solved immediately to avoid more problems. Therefore, it is very important to understand the precautions about it.
The most common causes of Roots blower overload are: pipe blockage and abnormal friction.
1. You said that too much fan oil will not cause fan overload. Too small pulley can cause fan overload, slippage, smoke section, belt overcurrent, etc. The reason is that the pulley has small torque.
2. The second reason is the same as above, which increases the torque of the pulley.
3. It depends on what method you use to adjust the flow. When the pressure is constant, the shunt valve adjustment will not affect the pressure in the fan pipe. When the frequency conversion is adjusted, it depends on your actual power.
