三葉羅茨風機燒毀的原因及解決方法
Causes and solutions of burning of three blade roots blower
一、管道,管道的壓力是一個容易導致風扇溫度過高的因素,三葉羅茨風機根據不同口徑在出風口有固定數量的主管,如果人為改變有特殊要求的管道口徑,容易造成壓力減小,在養殖方面,主管往往比較細,如果修改主管道口徑,需要采取相應措施,保證風機壓力正常。
1、 The pressure of the pipe is a factor that easily leads to the excessive temperature of the fan. The three blade roots fan has a fixed number of main pipes at the air outlet according to different diameters. If the pipe diameter with special requirements is artificially changed, it is easy to reduce the pressure. In terms of breeding, the main pipes are relatively thin. If the diameter of the main pipe is modified, corresponding measures need to be taken to ensure the normal pressure of the fan.
二、工作環境,按照正常的設計標準,風機應該在風機泵房內運行,但根據筆者多年的經驗,大多數三葉羅茨風機都是露天運行的,夏季因素的影響更加明顯,如果條件允許,現場可配備制冷降溫設備,盡可能避免環境因素對風機的影響,或配備隔音罩,配備散熱裝置。
2、 Working environment: according to the normal design standard, the fan should operate in the fan pump room. However, according to the author's many years of experience, most three leaf roots fans operate in the open air, and the influence of summer factors is more obvious. If conditions permit, refrigeration and cooling equipment can be equipped on site to avoid the influence of environmental factors on the fan as far as possible, or sound insulation cover and heat dissipation device can be equipped.
三、風扇的配置,風扇的壓力隨著風量的變化是恒定的,但是經常會有小馬拉車的情況,也就是小電機帶大風扇,這樣,為了滿足使用流量要求,風扇會對電機造成比較大的負荷,從而導致電機燒壞,風扇燒壞。
3、 The configuration of the fan and the pressure of the fan are constant with the change of the air volume, but there are often cases of a pony pulling a cart, that is, a small motor with a large fan. In this way, in order to meet the flow requirements, the fan will cause a relatively large load on the motor, resulting in the motor burning out and the fan burning out.
四、安裝風扇,如果剛開始新風扇的流量壓力沒有問題,沒有過載或者發熱,但是過一段時間就會開始燃燒,說明風扇需要重新檢查皮帶的松緊度,重新擰緊固定螺絲。
4、 Install the fan. If there is no problem with the flow pressure, overload or heating of the new fan at the beginning, but it will start to burn after a period of time, it indicates that the fan needs to recheck the tightness of the belt and retighten the fixing screws.
三葉羅茨風機操作規程
Operating procedures for three blade roots blower
一、三葉羅茨風機開機前的準備和檢查
1、 Preparation and inspection of three blade roots blower before startup
電壓波動值在380V10%范圍內,三相電源不能異相;儀表和電氣設備應完好,需接地的電氣設備應可靠接地;風機與管道的連接,框架螺栓等,應緊固;齒輪箱中的潤滑油應按照指定的品牌進行標記,并添加到機油標記線上;啟動前用手轉動滑輪2~3次,看有無異常;風機出口閥關閉,放空閥全開。
The voltage fluctuation value is within 380v10%, and the three-phase power supply cannot be out of phase; Instruments and electrical equipment shall be intact, and electrical equipment to be grounded shall be reliably grounded; The connection between fan and pipeline, frame bolts, etc. shall be fastened; The lubricating oil in the gearbox shall be marked according to the specified brand and added to the oil marking line; Before starting, rotate the pulley by hand for 2 ~ 3 times to see if there is any abnormality; The outlet valve of the fan is closed and the vent valve is fully opened.
二、三葉羅茨風機開始運行
2、 Three blade roots blower starts operation
打開三葉羅茨風機排氣閥和排氣閥;啟動電源,30秒后,如無異?,F象(如金屬摩擦、電流過大等),逐漸關閉排氣閥,使其正常運行;正常運行時,切勿關閉出口閥,以免發生爆裂事故;如果同時打開幾個風扇,應該先打開一個,空載運行正常后再打開另一個,空載運行正常后(30秒),關閉排氣閥。
Open the exhaust valve and exhaust valve of three blade roots blower; Start the power supply. After 30 seconds, if there is no abnormal phenomenon (such as metal friction, excessive current, etc.), gradually close the exhaust valve to make it operate normally; During normal operation, do not close the outlet valve to avoid bursting accident; If several fans are turned on at the same time, one should be turned on first, and then the other should be turned on after the no-load operation is normal. After the no-load operation is normal (30 seconds), close the exhaust valve.
三、關機操作
3、 Shutdown operation
停機前做好記錄,記下電壓、電流、風壓、溫度、運行時間等數據,逐步打開排氣閥;按下停止按鈕;關閉排氣閥。
Make records before shutdown, record the voltage, current, wind pressure, temperature, operation time and other data, and gradually open the exhaust valve; Press the stop button; Close the exhaust valve.
四、風扇的巡視
4、 Inspection of fan
風機正常運行后,每小時巡視一次,記錄儀表讀數(電壓、電流、風壓、溫度等)每2~3小時一次,巡視時,注意風扇聲音是否正常,運轉時不應有摩擦聲和撞擊聲,如有異常,立即停機檢查。
After the fan operates normally, patrol inspection shall be conducted once every hour, and the instrument readings (voltage, current, wind pressure, temperature, etc.) shall be recorded once every 2 ~ 3 hours. During patrol inspection, pay attention to whether the fan sound is normal, and there shall be no friction sound and impact sound during operation. If there is any abnormality, stop the machine immediately for inspection.
