Troubleshooting of precision dispensing valve

The conditions that may easily occur during the use of precision Dispensing nozzle valve may include excessive bubbles in the fluid, inconsistent glue outlet size, instantaneous glue blockage on the rubber valve joint and pipeline, etc. With the continuous development of precision dispensing valve and the summary of experience, there are better solutions to these faults.

Precision Dispensing nozzle valve plays a very positive role in many modern industries, such as hot melt adhesive application industry, photoelectric industry, biochemical industry, optics, photovoltaic solar energy industry, surface mount semiconductor manufacturing industry, pharmaceutical industry and many other high-tech and high-tech industries, but its work in these fields will still happen, So is there a corresponding fault solution when a fault occurs? Next, the troubleshooting of precision Dispensing nozzlevalve will be analyzed.

1.Bubbles in the fluid are too large

Solution: to reduce the fluid pressure, use a conical inclined needle.

2. Inconsistent glue size

Solution: when the glue output is inconsistent, it is mainly caused by the unstable pressure of the pressure cylinder storing the fluid or the air pressure. The inlet pressure regulator should be set at 10-15psi lower than the lower pressure in the plant. The pressure used by the pressure cylinder should be between the pressure above the middle of the regulator, and the pressure between the low pressure part of the pressure gauge should be avoided.

3. The instant glue is blocked on the precision Dispensing nozzle valve joint and pipeline

Solution: this situation is mainly due to excessive moisture or reused instant glue. Ensure to use fresh instant glue and thoroughly clean the pipeline with aceton acetone without moisture. The air used shall be determined to be dry, and a filter shall be installed between the air pressure and rubber valve system in the plant.

Through the analysis of the above three faults, we can preliminarily understand the faults of precision Dispensing nozzle valve and the corresponding solutions. For the precision dispensing valve, because it is used in special occasions, it must be handled in time when it fails, not only to protect the equipment, but also to ensure work efficiency.
