Basic Concepts of Capillary Tube Size
The size of a capillary tube directly affects the water spray effect, just as the size of a water pipe determines the water flow rate. Common capillary tube inner diameters range from 0.1 to 2 millimeters, depending on the application requirements. Too thin and it's prone to clogging; too thick and it won't create the desired mist effect. Liquid properties, pressure, and environmental factors must be considered when choosing a capillary tube.
Cut Size Selection for Different Scenarios
Agricultural Irrigation: Typically uses an inner diameter of 0.5-1 millimeters to ensure uniform spraying and prevent clogging.
Industrial Cooling: Uses an inner diameter of 1-2 millimeters to meet high flow rate requirements.
Laboratory Instruments: Precise to 0.1-0.3 millimeters for accurate control.
Household Humidification: 0.3-0.5 millimeters balances atomization and durability.
Common Misconceptions and Precautions
Many people believe that the thinner the capillary tube, the better the water spray effect, but this is a misconception. An excessively thin capillary tube leads to increased pressure loss, which actually reduces spray efficiency. Furthermore, water hardness and suspended solids content affect the lifespan of the capillary tube. Regular inspection and cleaning are key to keeping capillaries in good working order.
