Cooling method for Roots blower:

1.一般罗茨鼓风机我们有隔音设备。在夏天，我们须打开隔音罩门。隔音罩形成有限的空间，该空间会提高环境温度，从而导致吸入空气的温度较高，而出口温度较高。在夏季，许多带有隔音罩的罗茨鼓风机的入口温度都超过45度。除了排气风机外，还有一种是将吸气消声器放在外面

1. generally, we have sound insulation equipment for Roots blower. In summer, we have to open the soundproof enclosure door. The acoustic enclosure forms a limited space, which will increase the ambient temperature, resulting in a higher temperature of the intake air and a higher temperature of the outlet. In summer, the inlet temperature of many roots blowers with acoustic enclosures exceeds 45 ℃. In addition to the exhaust fan, there is also a suction muffler placed outside

2.如果风机安装在室内。可以安装空调。不用担心空调和电费。由于电动机温度升高10度，因此预期寿命要低得多。因此，室内空调可以延长设备的使用寿命并降低出口温度

2. if the fan is installed indoors. Air conditioning can be installed. Don't worry about air conditioning and electricity. The life expectancy is much lower because the motor temperature rises by 10 degrees. Therefore, indoor air conditioning can prolong the service life of the equipment and reduce the outlet temperature

3.降低入口和出口压力可以帮助我们降低温度。

3. reducing the inlet and outlet pressure can help us reduce the temperature.

4.减少管道等的弯曲，并尽可能减少管道压力损失和其他压力损失

4. reduce the bending of pipes, etc., and reduce the pressure loss of pipes and other pressure losses as much as possible

罗茨鼓风机产生脉动的原因：

Causes of pulsation of Roots blower:

1.罗茨鼓风机在壳体内部，两个互为反方向匀速旋转的叶轮与壳体内壁及各叶轮之间始终保持微小的间隙。

1. roots blower is inside the shell. Two impellers rotating at a uniform speed in opposite directions to each other always maintain a small gap between the inner wall of the shell and each impeller.

2.由于一个叶轮通过吸入口时与壳体内壁所包围的一定量的气体，由吸入侧输送到高压侧，如此循环，连续运行

2. as a certain amount of gas surrounded by the inner wall of the shell when an impeller passes through the suction port, it is transmitted from the suction side to the high pressure side, so it circulates and operates continuously

3.叶轮顶部到达排风口的一瞬间，排风侧的高压气体在机壳内逆流而被压缩

3. at the moment when the top of the impeller reaches the exhaust outlet, the high-pressure gas at the exhaust side is compressed by countercurrent in the casing

4.因叶轮与风机壳体内壁各叶轮之间始终保持微小的间隙，风机出口的部分气体通过间隙回流，这些回流气体伴随着急激压力变化而产生脉动

4. since there is always a small gap between the impeller and the impellers on the inner wall of the fan casing, part of the gas at the outlet of the fan flows back through the gap, and the returned gas will pulsation with the change of the rapid excitation pressure

罗茨鼓风机跳闸的原因：

Causes of Roots blower trip:

1.变频器的内部板块积压灰尘太多

1. too much dust is accumulated in the internal plate of the frequency converter

2.散热器积压灰尘太多，降低了机器本身的散热效果，使得罗茨风机变频器保护设备而跳闸

2. there is too much dust accumulated in the radiator, which reduces the heat dissipation effect of the machine itself and trips the roots blower frequency converter protection equipment

3.内部间隙太大，气体杂质、诱蚀等在罗茨风机内部沉积，导致转子与转子之间，转子与腔体等部位的间隙减小，进而增大了负载阻力，使得电机和变频器负荷过大导致机器跳闸保护

3. the internal clearance is too large, and gas impurities, induced corrosion, etc. are deposited inside the roots blower, resulting in the reduction of the clearance between the rotor and the rotor, between the rotor and the cavity and other parts, thus increasing the load resistance, resulting in excessive load on the motor and frequency converter, resulting in the tripping protection of the machine

4.变频器选型容量偏小，变频器选型时，应当注意应比电机的额定功率大20%左右，这样，当电机达到满负荷时，变频器仍然能够驱动

4. the type selection capacity of the frequency converter is too small. During the type selection of the frequency converter, it should be noted that it should be about 20% greater than the rated power of the motor, so that when the motor reaches full load, the frequency converter can still drive

5.供电电压过高或过低都会导致变频器过热而发生保护跳闸，供电电压超过410伏以上，会使变频器内部发热量加大，导致保护跳闸，供电电压低于360伏，会使变频器工作电流加大，罗茨风机出现过流保护跳闸

5. too high or too low supply voltage will lead to overheating of the frequency converter and protection tripping. If the supply voltage exceeds 410 V, the internal heat of the frequency converter will increase, resulting in protection tripping. If the supply voltage is lower than 360 V, the working current of the frequency converter will increase, and the overcurrent protection tripping of Roots blower will occur

6.变频器背部的整流模板有一路损坏，造成了其它两路工作时处于过流状态

6. one circuit of the rectifier template at the back of the frequency converter is damaged, causing the other two circuits to be in overcurrent state during operation

7.当遇到打雷天气或大型设备的启动会造成电网电压的波动，从而造成变频器失压保护跳闸

7. in case of thunderstorm weather or startup of large equipment, the grid voltage will fluctuate, resulting in the tripping of inverter voltage loss protection
