Cooling method for Roots blower:

1.一般羅茨鼓風機我們有隔音設備。在夏天，我們須打開隔音罩門。隔音罩形成有限的空間，該空間會提高環(huán)境溫度，從而導致吸入空氣的溫度較高，而出口溫度較高。在夏季，許多帶有隔音罩的羅茨鼓風機的入口溫度都超過45度。除了排氣風機外，還有一種是將吸氣消聲器放在外面

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.如果風機安裝在室內(nèi)?？梢园惭b空調(diào)。不用擔心空調(diào)和電費。由于電動機溫度升高10度，因此預期壽命要低得多。因此，室內(nèi)空調(diào)可以延長設備的使用壽命并降低出口溫度

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.降低入口和出口壓力可以幫助我們降低溫度。

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

4.減少管道等的彎曲，并盡可能減少管道壓力損失和其他壓力損失

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

羅茨鼓風機產(chǎn)生脈動的原因：

Causes of pulsation of Roots blower:

1.羅茨鼓風機在殼體內(nèi)部，兩個互為反方向勻速旋轉(zhuǎn)的葉輪與殼體內(nèi)壁及各葉輪之間始終保持微小的間隙。

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.由于一個葉輪通過吸入口時與殼體內(nèi)壁所包圍的一定量的氣體，由吸入側(cè)輸送到高壓側(cè)，如此循環(huán)，連續(xù)運行

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.葉輪頂部到達排風口的一瞬間，排風側(cè)的高壓氣體在機殼內(nèi)逆流而被壓縮

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.因葉輪與風機殼體內(nèi)壁各葉輪之間始終保持微小的間隙，風機出口的部分氣體通過間隙回流，這些回流氣體伴隨著急激壓力變化而產(chǎn)生脈動

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

羅茨鼓風機跳閘的原因：

Causes of Roots blower trip:

1.變頻器的內(nèi)部板塊積壓灰塵太多

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

2.散熱器積壓灰塵太多，降低了機器本身的散熱效果，使得羅茨風機變頻器保護設備而跳閘

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.內(nèi)部間隙太大，氣體雜質(zhì)、誘蝕等在羅茨風機內(nèi)部沉積，導致轉(zhuǎn)子與轉(zhuǎn)子之間，轉(zhuǎn)子與腔體等部位的間隙減小，進而增大了負載阻力，使得電機和變頻器負荷過大導致機器跳閘保護

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.變頻器選型容量偏小，變頻器選型時，應當注意應比電機的額定功率大20%左右，這樣，當電機達到滿負荷時，變頻器仍然能夠驅(qū)動

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.供電電壓過高或過低都會導致變頻器過熱而發(fā)生保護跳閘，供電電壓超過410伏以上，會使變頻器內(nèi)部發(fā)熱量加大，導致保護跳閘，供電電壓低于360伏，會使變頻器工作電流加大，羅茨風機出現(xiàn)過流保護跳閘

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.變頻器背部的整流模板有一路損壞，造成了其它兩路工作時處于過流狀態(tài)

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.當遇到打雷天氣或大型設備的啟動會造成電網(wǎng)電壓的波動，從而造成變頻器失壓保護跳閘

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
