In the previous articleJiangsu Bolet air compressorXiaobian to introduce to you《Mute the main role of the solenoid valve on the air compressor》In this article, Jiangsu Bolet Air Compressor Xiaobian will give you a detailed introductionSilent oil-free air compressorSolenoid valve leakageWhat is the reason？

First, the main reasons for the leakage of the magnetic valve of the silent oil-free air compressor:

1. Aging or damage of seals

With the increase of use time, the seals inside the solenoid valve (such as rubber pads, O-rings, etc.) will gradually age or wear, leading to a decline in sealing performance, resulting in gas leakage。

Frequent start-stop or long-term high-pressure working conditions will also accelerate the aging and damage process of seals。

2. The electromagnetic coil is faulty

The solenoid coil is the key component to control the solenoid valve switch. If the coil is short-circuited, broken or burned out, it will cause the solenoid valve to fail to close normally, resulting in air leakage。

Factors such as prolonged continuous operation, unstable voltage or excessive current can cause damage to the electromagnetic coil。

3. Improper installation and maintenance

When the solenoid valve is installed, it is not strictly in accordance with the requirements of the manual, such as the sealing surface is not cleaned, the fastening screws are not tightened, etc., which will affect the sealing performance of the solenoid valve。

Long-term lack of necessary maintenance, such as not regularly cleaning the inside of the valve body, not timely replacement of aging seals, etc., will also lead to silent oil-free air compressor magnetic valve leakage。

4. Working environment factors

The working environment temperature is too high or too low may affect the normal operation of the solenoid valve。In high temperature environment, seals are easy to age;At low temperatures, the lubricating oil inside the solenoid valve may solidify, causing the moving parts to stick。

Dust and impurities in the air may also enter the interior of the solenoid valve, causing blockage or wear, and then causing air leakage。

5, product quality problems

Some solenoid valve products due to the manufacturing process is not fine, improper material selection and other reasons, there are quality defects themselves, after a period of use is prone to air leakage and other problems。

二、Silent oil-free air compressor magnetic valve leakageSolutions and preventive measures

1, regular inspection and maintenance

Check the solenoid valve regularly, including appearance check, sealing performance test and electromagnetic coil resistance measurement, to find and deal with potential problems in a timely manner。

Regularly clean the solenoid valve inside, remove dust, impurities and oil, etc., to keep the valve body clean。

According to the use and manufacturer's recommendations, regularly replace the aging seals and lubricating oil to ensure that the solenoid valve is in good working condition。

2, correct installation and operation

When installing the solenoid valve, ensure that the sealing surface is clean and free of debris, and the fastening screws are properly tightened。

In the process of use, avoid frequent start and stop and long-term continuous work to reduce the impact and wear of the solenoid valve。

3. Optimize the working environment

As far as possible, keep the temperature and humidity of the working environment within the appropriate range to avoid the impact of extreme environment on the solenoid valve。

Strengthen the maintenance and management of the air filtration system to reduce dust and impurities in the air into the solenoid valve。

4, choose high quality products

When choosing a solenoid valve, you should choose products from well-known brands, reliable quality and stable performance。

Pay attention to the product certification and user reviews and other information to ensure that the purchase of high-quality products that meet their needs。

5, timely maintenance and replacement

Once the solenoid valve is found to be leaking and other abnormal conditions, it should be stopped immediately for inspection and repair or replacement。

If the fault of the solenoid valve is serious or the maintenance cost is high, you are advised to replace the solenoid valve directly to ensure the normal operation and safety of the device。
