  • 本站编辑:杭州力诺机械设备有限公司发布日期:2020-02-10 18:46 浏览次数:
吸附式干燥机如果运转不正常或者发生故障,压缩空气的质量就会出现问题,从而威胁到设备和产品。所以,企业应该定期检查保养设备,确保设备正常运作,如遇不能解决的问题,要及时联系厂家。
首先,我们要先了解一下吸干机的工作过程,观察吸干机的运行过程,各个控制器是否对应各个电磁阀和气动阀的相应动作,吸附式干燥机在吸附腔内一直保持满压状态,干空气进入再生的腔体会有一个再生过程。
模芯干燥机吸附阶段
湿压缩空气自入口进入进气缓冲腔,自下而上均匀通过各模芯吸附腔体;内分子筛利用自身毛细作用吸取压缩空气中的水分,达到干燥效果。
模芯干燥机再生阶段
微热再生,再生干空气经再生气流调节阀进入再生组出气汇流腔,高温干气体在再生组模芯吸附腔内膨胀减压至大气压后,自上而下对再生组分子筛进行吹扫,吸附剂会加快体内水分与吸附剂的分离,解析于干空气中,同再生气体一起自消音器排出。
只有全面了解吸干机的工作过程,才能更容易应对出现的各种问题。

露点过高
1、进气质量达不到指定标准
处理方法:调整进气压力和温度。
2、再生气量太小
处理方法:调节再生气阀门(一定确保两组开合程度一致),或联系售后服务人员。
3、管道
处理方法:旁通阀是否关严,干燥后的气体是否与其它管道气体连通。
故障停机
1、自动断电
原因分析:电路过载
处理方法:检查电路并更换短路元件。
2、低压停机
原因分析:进气气压过低
处理方法:将进气气压调整到指定标准。
3、高温停机
原因分析:温控模块线路连接异常、固态继电器或感温探头工作异常。
处理方法:检查温控模块连接线路、固态继电器及感温探头,若存在异常或损坏,须及时更换。
吸附式干燥机必须要通过后期的维护保养才能保证其运行的稳定性以及延长其使用寿命,所以,企业一定要重视吸附式干燥机的维护保养,保证其正常运转,才能保证生产的可靠性。

If the adsorption dryer runs abnormally or breaks down, the quality of compressed air will have problems, thus threatening the equipment and products. Therefore, the enterprise should check and maintain the equipment regularly to ensure the normal operation of the equipment. In case of any problem that cannot be solved, the enterprise should contact the manufacturer in time.
First of all, we need to understand the working process of the dryer, observe the operation process of the dryer, whether each controller corresponds to the corresponding action of each solenoid valve and pneumatic valve, the adsorption dryer keeps full pressure in the adsorption chamber all the time, and there will be a regeneration process when the dry air enters the regeneration chamber.
Adsorption stage of core dryer
The wet compressed air enters into the air inlet buffer chamber from the inlet and evenly passes through each mold core to absorb the cavity from the bottom to the top; the inner molecular sieve absorbs the moisture in the compressed air by its own capillary action to achieve the drying effect.
Regeneration stage of core dryer
Micro thermal regeneration: the regeneration dry air enters the regeneration group outlet manifold chamber through the regeneration air flow regulating valve. After the high-temperature dry gas expands and decompresses to atmospheric pressure in the absorption chamber of the regeneration group mold core, the molecular sieve of the regeneration group is purged from top to bottom. The adsorbent will speed up the separation of water and adsorbent in the body, resolve in the dry air, and discharge from the muffler together with the regeneration gas.
Only by fully understanding the working process of the dryer, can it be easier to deal with various problems.
Abnormal pressure display
1. Pressure sensor damaged
Treatment: replace the new pressure sensor.
2. Leakage or blockage of solenoid valve group
Handling method: clean the electromagnetic valve seat and muffler, if damaged, it must be replaced.
3. Blocked or broken air pipe
Handling method: check whether the tracheal ventilation is normal. If there is any abnormality, replace it immediately.
4. The pressure plate of valve seat falls off or is damaged
Treatment: check the pressing plate and replace it if necessary.
5. Cylinder damage
Handling method: check whether the cylinder operates normally and replace it if necessary.
6. Spring elastic deactivation of check valve
Treatment: replace the spring.
7. Solenoid muffler blocked
Handling method: dismantle and clean the muffler. If it is blocked or seriously damaged, replace it immediately.
8. Flow of regeneration gas
Treatment: reduce the opening and closing degree of (regeneration air flow) control valve (Note: the regeneration air flow control valve must ensure the same opening and closing degree). If there is any abnormality in the check valve and intake valve, replace them if necessary.
Abnormal operation of controller program
1. Controller damaged
Handling method: check the controller. If it is damaged, replace it immediately.
After drying, the gas contains a small amount of water
1. Too large flow or too high oil content with air compressor
Handling method: check whether the air compressor works normally
2. There is a lot of rust in the air supply main pipe, blocking the silencer valve
Treatment method: drain and clean the rust inside the pipeline and air tank, and clean the dirt at the lower end of the muffler.
High dew point
1. Intake air quality does not meet the specified standard
Treatment: adjust the intake pressure and temperature.
2. Regeneration gas volume is too small
Treatment method: adjust the regeneration gas valve (make sure the opening and closing degree of the two groups are the same), or contact the after-sales service personnel.
3, pipeline
Treatment method: whether the bypass valve is closed tightly, and whether the dried gas is connected with other pipeline gas.
Fault shutdown
1. Automatic power off
Cause analysis: circuit overload
Treatment: check the circuit and replace the short circuit element.
2. Low pressure shutdown
Cause analysis: low intake air pressure
Treatment: adjust the air inlet pressure to the specified standard.
3. High temperature shutdown
Cause analysis: abnormal circuit connection of temperature control module, abnormal operation of solid-state relay or temperature sensing probe.
Handling method: check the connecting circuit of temperature control module, solid-state relay and temperature sensing probe. If there is any abnormality or damage, replace it in time.
Adsorption dryer must be maintained in the later period to ensure its stability and extend its service life. Therefore, the enterprise must pay attention to the maintenance of adsorption dryer to ensure its normal operation to ensure the reliability of production.
