If the material level of the foam machine is not measured, there will be problems such as density deviation of foamed particles, particle agglomeration, too wet particles, particle shrinkage, and unstable magnification. Serious or even lead to the batch of material failure.
If material overflow occurs due to inaccurate measurement of the material level of the pre-expeller, the pre-expander will be shut down for cleaning, which will reduce the production efficiency.
The density of the medium in the pre-expansion machine of the foam machinery is low, which cannot be measured by ordinary level switches. The medium in the pre-expansion machine contains water vapor, which makes the material easy to adhere to the probe and cause the problem of hanging material.
Most of the medium in the pre-engine is white particles, and the photoelectric switch is incompetent due to its own limitations, and often false alarms.
Foam machinery has anti-hanging ability, and the measurable density is as low as 8g/L. Foam machinery is widely used in life.
