羅茨風機跳閘應該怎么維修?

羅茨風機設備在使用可能會遇到跳閘的情況,這時候可能很多人一時間想到的是功率過大導致的,其實引起這種情況有很多種原因。

Roots blower may encounter tripping when it is in use. At this time, many people may think that it is caused by excessive power. In fact, there are many reasons for this situation.

先來看一下設備的使用要求吧:輸送進口介質的溫度不得超過40,介質中微粒雜質含量不得超過1000mg/m3,顆粒尺寸不得小于0,1MM。采用加壓時,不應超過鼓風機銘牌上規定的額定加壓值。由于風機的結構特殊,根據工作需要,它與其它風機有許多不同,因此需要注意。

First of all, let's take a look at the use requirements of the equipment: the temperature of the imported medium shall not exceed 40, the content of particulate impurities in the medium shall not exceed 1000 mg / m3, and the particle size shall not be less than 0,1 mm. When pressurization is adopted, it shall not exceed the rated pressurization value specified on the blower nameplate. Due to the special structure of the fan, according to the needs of work, it is different from other fans, so we need to pay attention to it.

一、簡單的跳閘

1、 Simple trip

這種情況下,羅茨風機有簡單的跳閘現象,不易對其造成損壞。打開安全減壓閥,啟動離心風機,檢查風機是否正常工作。

In this case, roots blower has a simple trip phenomenon, which is not easy to cause damage. Open the safety relief valve, start the centrifugal fan, and check whether the fan works normally.

二、因其他原因而發生的跳閘。

2、 Tripping due to other reasons.

1.電動機燒壞。

1. The motor is burnt out.

若電動機燒壞,無法啟動羅茨風機,則須拆換電動機。羅茨風機不能承受壓力,壓強過大容易損壞電機,離心風機內力工作壓力急劇上升,可能出現嚴重情況。

If the motor is burnt out and the roots blower cannot be started, the motor must be removed and replaced. The roots blower can not bear the pressure, too much pressure is easy to damage the motor, and the internal force working pressure of the centrifugal blower rises sharply, which may cause serious situation.

2.雷雨天氣或大中型機械設備起動時,會引起電網工作電壓的波動,造成變頻器超壓維護跳閘。

2. Thunderstorm weather or start-up of large and medium-sized mechanical equipment will cause the fluctuation of power grid working voltage, resulting in the maintenance trip of frequency converter overpressure.

3.長時間不能清除,造成變頻器內板積塵過多或熱管式散熱器積塵過多,使積塵減少設備本身熱排放的實際效果,造成變頻器因維修機器設備而斷電。

3. If it can't be removed for a long time, it will cause too much dust on the inner plate of the frequency converter or too much dust on the heat pipe radiator, which will reduce the actual effect of the heat emission of the equipment itself, resulting in the power failure of the frequency converter due to the maintenance of machinery and equipment.

4.電源系統工作電壓過高或過低都會導致變頻器過熱,從而導致維修中斷。當電源系統的工作電壓超過410V時,變頻器內部的熱值就會增加,從而導致維修中斷。當電源系統的工作電壓低于360V時,變頻器的工作電流就會增加,造成保護跳閘的過電流。

4. If the working voltage of power system is too high or too low, the inverter will overheat, resulting in maintenance interruption. When the working voltage of the power supply system exceeds 410v, the internal calorific value of the inverter will increase, resulting in the interruption of maintenance. When the working voltage of the power supply system is lower than 360V, the working current of the inverter will increase, resulting in the over-current of the protection trip.

5.變頻器本身的難題,變頻器等整流器模板全部損壞,在其它雙作業中出現過流情況,引起跳閘。

5. Due to the problem of the frequency converter itself, the rectifier templates such as the frequency converter are all damaged, and the over-current situation occurs in other dual operation, causing tripping.

如果遇到這種情況,及時地根據產生的原因來進行解決即可!

If you encounter this situation, timely according to the causes to solve!
