PZhS unit
PZhS unit for polarizing piezoelectric ceramic elements in liquid medium
The unit allows polarizing a wide range of piezoelectric ceramic elements made of most piezoceramic materials.
Features and Specifications
Polarized sample dimensions:
- Diameter or diagonal of a square, max 30 mm
- Height (interelectode spacing), max 8 mm
This equipment provides maximum electric field strength in piezoceramic elements due to additional insulation of interelectrode surfaces of PE with dielectric liquid, which makes it highly valuable for design and development of new piezoelectric materials and piezoceramic elements. Another important advantage is uniform heating and cooling of piezoceramic elements, which is crucial for polarizing large-size samples.
- Polarization voltage range, from 0,5 to 20 kV
- Maximum field strength 2,0...2,5 kV/mm
- Potential capacity, min 70 item per hour
- Maximum heating temperature up to 150 С°
- Continuous operation time 8 hours
- Power consumption, max 2500 W
- Dimensions, max 1200х690х2400 mm
Piezoceramic element dimensions can be increased by means of decreased performance.
PVS-5 unit
PVS-5 unit for polarizing piezoelectric ceramic elements in air medium
PVS-5 unit uses a rotary conveyer type to polarize piezo element blanks without a liquid dielectric.
Features and Specifications
Polarized sample dimensions:
Rings, disks, plates
- external diameter, square side 10...30 mm
- interelecrode spacing 0,5...8 mm
The unit provides high productivity and allows polarizing a wide range of piezoelectric ceramic elements of different size and configuration. The advantages of the unit are
• electrodes and piezoelectric elements are not exposed to a liquid dielectric, which is particularly important for subsequent adhesion;
• dielectric and washout liquids free polarization process reduces production costs through eliminating additional technological and environmental challenges.
- Polarization voltage range 0.3 to 10 kV
- Maximum field strength 0,8...1,2 kV/mm
- Potential capacity, max 1200 pcs/h
- Maximum heating temperature 500 ºC
- Continuous operation time 8h
- Static rotor conveyor exposure time 1 to 300 sec
- Piezo elements loading and offloading manual
- Power consumption, max 4000 W
- Mass, max 200 kg
- Dimensions, max 1800x600x1500 mm
The unit is intended for both serial production and large-scale manufacturing of piezoceramic products.
PVSK unit
PVSK unit for polarization of large-size piezo elements made of ferrorigid materials in air medium
PVSK unit provides a chamber type polarization of large-size piezo element blanks made of ferrorigid materials without a liquid dielectric.
Features and Specifications
Polarized sample dimensions:
Disks
- diameter 30...80 mm
- interelecrode spacing 3...12 mm
Rings
