专注通风管道加工·排烟罩

正常来说，合格规范的油烟净化器在运行中一般是没有什么噪音的，就算是有也应该是离心风机在运转时所产生的噪声。若是在厨房里听到噼里啪啦响声时，这就说明油烟净化设备应该出现问题。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.输入电压过高

1. input voltage is too high

油烟净化器电源的电场均为高压，电流电压值应保持在合理的使用范围内。

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.

解决方法：检查电压是否正常，一旦发现电压过高，需要降低电压。这时好联系厂家的人员或售后人员调整电压。

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、油烟净化器的电场板上有水

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

餐厅的厨房环境也有比较多的水。烹饪产生的水蒸气混入厨房油烟中，通常水是导电的。放电声。此外，即使没有完全干燥的电场在清洗后安装在机箱内，也会发出噼啪声。

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.

解决方法：正确的操作是关闭电源。清洁内部后，必须将电场干燥。还需要用风扇吹电场30分钟左右把水吹干。

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、济南油烟净化器的电场板间有异物，正负极连接短路，或电源线损坏。

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.

电源线与高压电场相连，所以导线的完整性非常重要！如果电线的绝缘有一处损坏，其中的高压电接触空气，可能会发出“噼啪”的声音。此时电源正负极短路。此外，电场板内部不能有杂物无法连接。一旦出现噼啪声，并伴有电火花的出现，则存在火灾隐患。

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.

解决方法：确保油烟净化器电极板之间的正负极连接正确，避免极板间有异物。同时，在选择电源线时应选用的加强绝缘。

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.极板或齿条变形

4. deformation of polar plate or rack

油烟净化器内部的电场在使用一段时间后需要清理干净。很有可能餐饮用户在清洁过程中不小心把盘子或架子弄变形了，这里也会有噼啪声。

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.

解决方法：安装、拆卸或清洗时掉落会导致这种情况被发现，所以安装时检查极板是否变形，如果变形过大，用铁钳修复。

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.损坏的绝缘子

5. damaged insulator

绝缘子是电力连接电场的重要组成部分，在油烟净化器中起到隔离电场和避免泄漏的作用。如果绝缘体损坏，引起电场泄漏，一旦高压接触潮湿空气，就会发出噼里啪啦的声音。

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.

解决方法：关闭电源。检查绝缘体。（此时我们也提醒大家，清洁电场时不要忘记清洁绝缘体。）如果绝缘体损坏，必须更换。

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.地线连接不正确

6. incorrect ground wire connection

出于考虑，很多油烟净化器在安装时都需要安装地线。油烟净化器必须水平安装。净化器必须可靠接地（有三根出线，红线和绿线相连，黄线和绿线接地）。如果电流和电压过高的话，很有可能会因为高压放电而发出“噼啪”的声音。

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.

解决方法：济南油烟净化器厂家建议您检查并接好地线，做好电气安装保护。

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