Is the solenoid valve for vibration plate suitable for high-viscosity fluid control?
Publish Time: 2025-05-29
In industrial automation and precision fluid control systems, solenoid valves are used as key actuators for on-off control of various liquids and gases. Among them, solenoid valves for vibration plates are widely used in the field of microfluid control, such as inkjet printing, medical infusion systems, and laboratory analysis equipment, due to their compact structure, fast response speed, and low power consumption.
Effect of high-viscosity fluids on solenoid valve performance
Due to their poor fluidity, high-viscosity fluids will generate greater resistance when passing through the valve channel. For traditional solenoid valves for vibration plates, their drive mechanism design is mainly used to overcome smaller flow resistance. Therefore, in practical applications, if the standard solenoid valve for vibration plate is used directly to control high-viscosity media, problems such as incomplete opening, delayed closing, or flow fluctuations may occur, which in turn affects the control accuracy and stability of the system.
In addition, high-viscosity fluids are also prone to residues in the valve body, especially in the working state of frequent opening and closing. These residues may gradually accumulate, causing the valve to become stuck or even fail. This phenomenon is particularly obvious in high or low temperature environments, further exacerbating the operating risk of the solenoid valve.
Design optimization direction of solenoid valve for vibration plate
Although ordinary solenoid valve for vibration plate has limitations in high-viscosity fluid control, it can still achieve relatively ideal application effects through targeted design improvements. First, the flow resistance of the fluid can be reduced and the passing capacity can be improved by increasing the diameter of the internal channel of the valve or optimizing the flow channel structure. Secondly, the electromagnetic force output of the driving component is enhanced so that the vibration plate can more effectively overcome the viscous resistance, thereby ensuring the normal opening and closing of the valve.
Material selection is also one of the key factors to improve applicability. High-viscosity fluids often have certain corrosiveness or chemical activity. Therefore, the selection of corrosion-resistant, smooth-surfaced, and non-absorbent materials can help reduce clogging and scaling problems. At the same time, the material of the seal also needs to have good anti-expansion and wear resistance to cope with the challenges brought by long-term contact with high-viscosity liquids.
Considerations in practical applications
In the actual engineering of using solenoid valve for vibration plate for high-viscosity fluid control, multiple external factors need to be considered. For example, changes in operating temperature can affect the viscosity characteristics of the fluid, which in turn affects the response speed and control accuracy of the valve. Therefore, when selecting the valve, you should fully understand the viscosity change curve of the fluid at different temperatures, and evaluate the adaptability of the solenoid valve accordingly.
In addition, the control frequency is also a factor that cannot be ignored. High-frequency switching operations will accelerate the wear of the components inside the valve, especially when dealing with high-viscosity media, the friction and fatigue effects are more obvious. Therefore, it is recommended to appropriately reduce the operating frequency in high-viscosity fluid control situations, or adopt a special structural design with self-cleaning function to extend the service life.
Overall, as long as the fluid characteristics, working environment and system requirements are fully considered in the selection stage, the solenoid valve for vibration plate can still play an important role in high-viscosity fluid control and provide a reliable solution for precision control in related industries.
