Product Specifications

Technical details and manufacturing context for Solenoid/Piezoelectric Actuator

Definition
A critical actuation component within dosing valves and injectors that uses either electromagnetic (solenoid) or piezoelectric principles to generate controlled linear or rotary motion. It serves as the primary mechanism for opening, closing, or modulating fluid flow with high precision, enabling accurate metering of liquids or gases in industrial applications.
Working Principle
Solenoid actuators operate by energizing a coil to create a magnetic field that moves a ferromagnetic plunger. Piezoelectric actuators use the inverse piezoelectric effect where applied voltage causes dimensional changes in piezoelectric materials, generating precise displacement. Both convert electrical input into mechanical output to actuate valve mechanisms.
Common Materials
Electrical steel laminations, Copper wire, Piezoelectric ceramics (PZT), Stainless steel housing
Technical Parameters
  • Stroke length - the maximum linear displacement the actuator can produce (mm) Customizable
Components / BOM
  • Coil Assembly
    Generates electromagnetic field when energized in solenoid actuators
    Material: Copper wire with insulation
  • Plunger/Core
    Ferromagnetic component that moves in response to magnetic field in solenoid actuators
    Material: Electrical steel
  • Piezoelectric Stack
    Multiple piezoelectric elements that expand/contract with applied voltage in piezo actuators
    Material: Lead zirconate titanate (PZT) ceramics
  • Housing
    Protects internal components and provides mounting interface
    Material: Stainless steel or aluminum
  • Return Spring
    Returns actuator to default position when de-energized
    Material: Spring steel
Engineering Reasoning
0.1-100 bar pressure, 0-150°C temperature, 12-48 VDC electrical input
Mechanical failure at 120 bar pressure, thermal failure at 180°C, electrical failure at 60 VDC
Design Rationale: Solenoid: magnetic saturation at 1.6 T flux density causing force degradation; Piezoelectric: depolarization at 200°C Curie temperature causing displacement loss
Risk Mitigation (FMEA)
Trigger Voltage transient exceeding 60 VDC
Mode: Insulation breakdown in solenoid coil windings
Strategy: TVS diode clamping at 48 VDC with 1.5 kJ surge rating
Trigger Continuous operation at 180°C ambient temperature
Mode: Piezoelectric ceramic depolarization and permanent displacement reduction
Strategy: PTC thermistor thermal cutoff at 150°C with 10 ms response time

Frequently Asked Questions

What are the key differences between solenoid and piezoelectric actuators in fluid dosing applications?

Solenoid actuators use electromagnetic coils for linear motion, offering high force and speed, while piezoelectric actuators use ceramic stacks for nanometer precision with faster response but lower displacement. Both provide reliable dosing control in valves and injectors.

How does the material selection impact the performance and durability of these actuators?

Electrical steel laminations reduce eddy currents in solenoids, copper wire ensures efficient coil operation, PZT ceramics enable precise piezoelectric effects, and stainless steel housing provides corrosion resistance and structural integrity in harsh industrial environments.

What maintenance considerations are important for solenoid/piezoelectric actuators in machinery manufacturing?

Regular inspection of coil insulation, piezoelectric stack integrity, spring tension, and housing seals is essential. Ensure proper electrical connections and protect against contamination to maintain precise dosing performance and extend service life.
