What causes the proportional solenoid valve to be noisy?

Solenoid valve in the whole process of use of the more common fault problems are: can not operate normally, can not be terminated normally, abnormal operation, leakage, excessive noise, in which the noise is a lot of small partners will encounter common faults, what is the reason for the noise? Professional and technical personnel indicate that this may be related to the destruction of mechanical parts of the product itself, and may also be related to the working environment, below the specific analysis.

1, the specific working environment standards are not within the scope of product work

The working environment of the product is more complex, it is necessary to involve the working temperature, air relative humidity, physical environment temperature, material characteristics, pressure, etc., assuming that the working environment of the product can not be qualified, it will lead to instability in the work of the product, and even lead to parts damage and destruction rate faster, and even continue to lead to excessive noise in the work process.

In order to deal with it, it is necessary to change the products suitable for use in the current natural environment.

2, the destruction of product parts, such as torsion spring aging

All products will be destroyed and aged after a long time of use, the same is true of the micro medical solenoid valve, after a long time of use, the internal structural parts are inevitably damaged and destroyed, resulting in unstable product operation and relatively loud noise.

For such things, in order to deal with it, it is necessary to determine the situation, assuming that the damage of the parts is not more serious, the parts are reassembled after maintenance, assuming that the parts have become old and can not be used again, then replace the new parts.

3, the working voltage is too low

Too low current will also result in abnormal product operation, resulting in noise formation.

To deal with this problem, it is very simple, only necessary to increase the voltage can be.

4. The working pressure of system software is too high

Excessive system working pressure leads to the product can not be used in its applicable work in the field of work, causing the reliability of product operation to decline and the formation of noise.

In order to thoroughly deal with this problem, it is necessary to adjust the working pressure of the system software, and adjust the pressure to the field of product integration.

5, there are impurities in the control system, such as the valve heart or plunger pump nut surface impurities

In the operation of the signal response solenoid valve, external impurities (such as dust, oil stains, broken slag) are likely to enter, and impurities will form products that can not work well, resulting in noise when the product is working.

The way to deal with this is to regularly clean the product and remove impurities.

6. Short and smooth

In the long-term operation of the product, the middle of the parts will rub against each other, resulting in the lack of sufficient smooth in the middle of the parts, and the physical sliding friction will lead to relatively loud noise from the product.

Therefore, during the operation period of the product, it is necessary to check the smoothness of the parts (such as the shaft) on time, assuming that the smoothness is not enough, it is necessary to add smoothness.

7, parts loose

Loose parts usually lead to the structure of the product is not strong, because the reliability of the structure is poor, so the product will tremble when running, generally speaking, the greater the strength of the vibration, the greater the noise sent.

To deal with the problem thoroughly, it is necessary to stop the product from working, check what parts are loose, and tighten the fallen parts.

You can understand many factors that lead to the noise of the solenoid valve, such as the working environment is not suitable, parts damage, working voltage is too low, system software working pressure is too high, impurities intrusion, shortage of smooth, parts loose these. Noise caused by different reasons, the method of treatment is not the same, it is necessary to treat the symptoms.
