正常來說，合格規范的油煙凈化器在運行中一般是沒有什么噪音的，就算是有也應該是離心風機在運轉時所產生的噪聲。若是在廚房里聽到噼里啪啦響聲時，這就說明油煙凈化設備應該出現問題。那么究竟是怎么回事？

Normally, the qualified oil fume purifier generally has no noise during operation. Even if it does, it should be the noise generated by the centrifugal fan during operation. If you hear crackling noise in the kitchen, it means that there should be a problem with the fume purification equipment. So what's going on?

1.輸入電壓過高

1. input voltage is too high

油煙凈化器電源的電場均為高壓，電流電壓值應保持在合理的使用范圍內。

The electric field of the power supply of the oil fume purifier is high voltage, and the current and voltage values shall be kept within a reasonable range.

解決方法：檢查電壓是否正常，一旦發現電壓過高，需要降低電壓。這時好聯系廠家的人員或售后人員調整電壓。

Solution: check whether the voltage is normal. If the voltage is too high, reduce the voltage. At this time, it is good to contact the manufacturer's professional personnel or after-sales personnel to adjust the voltage.

2、油煙凈化器的電場板上有水

2. There is water on the electric field board of the fume purifier

餐廳的廚房環境也有比較多的水。烹飪產生的水蒸氣混入廚房油煙中，通常水是導電的。放電聲。此外，即使沒有完全干燥的電場在清洗后安裝在機箱內，也會發出噼啪聲。

The kitchen environment of the restaurant also has more water. Cooking steam is mixed into kitchen lampblack. Usually, water is conductive. Discharge sound. In addition, even if the electric field that is not completely dry is installed in the chassis after cleaning, it will make a crackling sound.

解決方法：正確的操作是關閉電源。清潔內部后，必須將電場干燥。還需要用風扇吹電場30分鐘左右把水吹干。

Solution: the correct operation is to turn off the power. After cleaning the interior, the electric field must be dried. You also need to use a fan to blow the electric field for about 30 minutes to dry the water.

3、濟南油煙凈化器的電場板間有異物，正負極連接短路，或電源線損壞。

3. There are foreign matters between the electric field plates of Jinan oil fume purifier, the positive and negative electrode connections are short circuited, or the power line is damaged.

電源線與高壓電場相連，所以導線的完整性非常重要！如果電線的絕緣有一處損壞，其中的高壓電接觸空氣，可能會發出“噼啪”的聲音。此時電源正負極短路。此外，電場板內部不能有雜物無法連接。一旦出現噼啪聲，并伴有電火花的出現，則存在火災隱患。

The power line is connected to the high-voltage electric field, so the integrity of the conductor is very important! If there is a damage to the insulation of the wire, and the high-voltage electricity contacts the air, it may make a "crackling" sound. At this time, the positive and negative poles of the power supply are short circuited. In addition, there shall be no sundries inside the electric field board that cannot be connected. In case of crackling sound accompanied by electric spark, there is a potential fire hazard.

解決方法：確保油煙凈化器電極板之間的正負極連接正確，避免極板間有異物。同時，在選擇電源線時應選用的加強絕緣。

Solution: ensure that the positive and negative electrodes between the electrode plates of the fume purifier are correctly connected to avoid foreign matters between the electrode plates. At the same time, high-quality reinforced insulation shall be selected when selecting the power line.

4.極板或齒條變形

4. deformation of polar plate or rack

油煙凈化器內部的電場在使用一段時間后需要清理干凈。很有可能餐飲用戶在清潔過程中不小心把盤子或架子弄變形了，這里也會有噼啪聲。

The electric field inside the oil fume purifier needs to be cleaned after being used for a period of time. It is very likely that the dining user accidentally deformed the plate or shelf during the cleaning process, and there will also be crackling noise here.

解決方法：安裝、拆卸或清洗時掉落會導致這種情況被發現，所以安裝時檢查極板是否變形，如果變形過大，用鐵鉗修復。

Solution: falling during installation, disassembly or cleaning will lead to this situation. Therefore, check whether the polar plate is deformed during installation. If the deformation is too large, repair it with iron pliers.

5.損壞的絕緣子

5. damaged insulator

絕緣子是電力連接電場的重要組成部分，在油煙凈化器中起到隔離電場和避免泄漏的作用。如果絕緣體損壞，引起電場泄漏，一旦高壓接觸潮濕空氣，就會發出噼里啪啦的聲音。

Insulator is an important part of electric field connected with power, and plays a role in isolating electric field and avoiding leakage in oil fume purifier. If the insulator is damaged, resulting in electric field leakage, once the high voltage contacts the humid air, it will make a crackling sound.

解決方法：關閉電源。檢查絕緣體。（此時我們也提醒大家，清潔電場時不要忘記清潔絕緣體。）如果絕緣體損壞，必須更換。

Solution: turn off the power. Check the insulator. (at this time, we also remind you not to forget to clean the insulator when cleaning the electric field.) If the insulator is damaged, it must be replaced.

6.地線連接不正確

6. incorrect ground wire connection

出于考慮，很多油煙凈化器在安裝時都需要安裝地線。油煙凈化器必須水平安裝。凈化器必須可靠接地（有三根出線，紅線和綠線相連，黃線和綠線接地）。如果電流和電壓過高的話，很有可能會因為高壓放電而發出“噼啪”的聲音。

For safety reasons, many fume purifiers need to be installed with ground wires. The fume purifier must be installed horizontally. The purifier must be reliably grounded (there are three outgoing lines, the red line and the green line are connected, and the yellow line and the green line are grounded). If the current and voltage are too high, it is likely to make a "crackling" sound due to high-voltage discharge.

解決方法：濟南油煙凈化器廠家建議您檢查并接好地線，做好電氣安裝保護。

Solution: the manufacturer of Jinan oil fume purifier suggests that you check and connect the ground wire, and protect the electrical installation.
