全自动清洗机各部分损坏该怎么修?

作者:超声波清洗机生产厂家 来源:http://www.jnthcsb.com 时间:2021-01-28 14:10:10

超声波清洗机除了具有自身的清洗功能外,还具有萃取、乳化、加速溶解、破碎、分散等多种功能。广泛应用于:机械、电子、塑料、仪器仪表、医药、包装、军工、航空航天等行业的制造、维修和清洗;实验材料的吸入管、吸嘴及用具的清洗,层析前脱气处理,医疗器械、医疗材料及用具的清洗;珠宝、首饰、贵金属、眼镜等的清洗。如果超声波清洗机各部分损坏该怎么修呢?下面我们就逐一来看下吧!

The ultrasonic cleaning machine not only has its own cleaning function, but also has many functions, such as extraction, emulsification, accelerated dissolution, crushing, dispersion and so on. It is widely used in the manufacturing, maintenance and cleaning of machinery, electronics, plastics, instruments, medicine, packaging, military industry, aerospace and other industries; cleaning of suction pipes, suction nozzles and appliances of experimental materials, degassing before chromatography, cleaning of medical devices, medical materials and appliances; cleaning of jewelry, jewelry, precious metals, glasses, etc. If each part of the ultrasonic cleaning machine is damaged, how to repair it? Now let's take a look at it one by one!

超声波清洗机各部分损坏该怎么修(图1)

1.保险损坏:

1. Insurance damage:

开机后如果没有电源显示或操作,首先要看电源插座里的保险是否烧坏。

If there is no power display or operation after power on, the first thing to see is whether the fuse in the power socket is burnt out.

分析:可能是用户的地线和活线或中性线,没有地面(这台机器的地线连接机器外壳),或者它可能是机器是短路的,组件老化有短路现象,导致损失的保险。

Analysis: it may be that the user's ground wire and live wire or neutral wire have no ground (the ground wire of this machine is connected to the machine shell), or it may be that the machine is short circuited, and the components are aging and short circuited, resulting in the loss of insurance.

建议检查:取出安全手表,检查是否有损坏,用万用表开关齿轮检查是否有损坏,如有损坏,更换新设备。

Suggested inspection: take out the safety watch and check whether it is damaged. Use the switch gear of the multimeter to check whether it is damaged. If it is damaged, replace it with new equipment.

2. 传感器损坏:

2. Sensor damage:

设备分析:有时由于机器长期使用,温度逐渐升高,导致胶体熔化,换能器脱落或换能器陶瓷部分断裂。

Equipment analysis: sometimes, due to the long-term use of the machine, the temperature gradually rises, resulting in the melting of the colloid, the falling off of the transducer or the fracture of the ceramic part of the transducer.

推荐检查:使用仪表测量传感器的绝缘强度。如果绝缘强度低于200Ω,一个新的传感器应更换。

Recommended inspection: use the instrument to measure the insulation strength of the sensor. If the insulation strength is less than 200 Ω, a new sensor should be replaced.

换能器内部的陶瓷也会因长期使用而损坏,影响正常工作。

The ceramic inside the transducer will also be damaged due to long-term use, affecting the normal work.

3.功率管损坏:

3. The power tube is damaged

分析:由于机器长时间连续使用,主板上的电源管将会短路。

Analysis: due to the continuous use of the machine for a long time, the power tube on the motherboard will be short circuited.

推荐测试:当功率管连接在主板上,用万用表测量电阻的别针两岸的功率管,应在正常条件下约22Ω。电源管拆下(与主板断开)后,不应在引脚之间连接。

Recommended test: when the power tube is connected to the motherboard, use a multimeter to measure the resistance of the pin on both sides of the power tube, which should be about 22 Ω under normal conditions. After the power tube is removed (disconnected from the motherboard), it should not be connected between pins.

4. 调节管损坏

4. The regulating pipe is damaged

分析:稳压器的损坏通常是由于功率管的阻值小或短路后的启动,很少损坏。

Analysis: the damage of voltage regulator is usually due to the small resistance value of power tube or the startup after short circuit, which rarely damages.

推荐检测:根据二极管特性,正向导通、反向截止。用万用表的二极管装置,正向电阻约为70Ω,反向电阻∞。当数值偏差过大或正电阻为∞时,应更换新的调节器。

Recommended test: according to diode characteristics, forward conduction and reverse cutoff. With the diode device of the multimeter, the forward resistance is about 70 Ω and the reverse resistance is ∞. When the value deviation is too large or the positive resistance is ∞, a new regulator should be replaced.

5. 桥损(二极管整流电路)

5. Bridge loss (diode rectifier circuit)

分析:与调节条件相同

Analysis: same as regulation condition

推荐测试:也可以根据二极管特性和方法进行测试(桥本身是由二极管组成的)

Recommended test: it can also be tested according to the diode characteristics and methods (the bridge itself is composed of diodes)

6. 控制板损坏(可调超声波清洗机)

6. The control board is damaged (adjustable ultrasonic cleaner)

分析:长期不间断工作,以及部件老化,清洗液的渗透也可能导致损坏。建议检查:停机,断开控制板和主板。主板上的电源。如果机器开始工作,控制板就会损坏。请替换它。

Analysis: long term uninterrupted work, as well as parts aging, the penetration of cleaning fluid may also cause damage. Recommended inspection: shut down, disconnect the control board and main board. The power supply on the motherboard. If the machine starts to work, the control board will be damaged. Please replace it.

7. 电感和隔离变压器损坏

7. The inductance and isolation transformer are damaged

分析:由于机器工作时间长,感应器和变压器都是散热元件,高温会熔化烧坏,造成短路。

Analysis: due to the long working time of the machine, the inductor and transformer are heat dissipation components, and the high temperature will melt and burn out, resulting in short circuit.

推荐检查:大部分损坏的电感、变压器都能直接看到烧焦痕迹。立即更换新部件。

Recommended inspection: most of the damaged inductors and transformers can see the burning marks directly. Replace the parts immediately.
