Sweep clock movements, also called the scanning movement, sweep clock movements of the second hand is going. Said to silent clock movement product type, We need to segment according to the quality movement and poor quality of movement, The use of its difference is very great. Ordinary scanning machine core, the quality is poor, Operation time although said that no ticking sound, But movement due to the internal circuit, the use of the stand or fall of the original, The degree of clean production environment, Silent clock movement in the process of the functioning of the work produces the sound of the continuous rotation, Disadvantages: not enough quiet, Large power consumption (1 battery 2-3 months will need to be replaced). In addition, the domestic high-quality mute machine core, the quality is relatively good, coil is large enough, And movement appearance material is good, durable and strong pressure, But good quiet movement price relatively more expensive than ordinary quiet movement points.
Domestic high-quality mute movement using the material! Domestic high-quality mute movement are commonly use ABS plastic material, because ABS plastic material has two benefits, 1. Material and environmental protection; 2. Smooth wear-resisting voice small machine core gear, shell stress is strong long life is not easy to aging. Movement using big plate circuit and coil motors (full copper thick paint line), Benefit is the power stable, not easy to burn machine, and low consumption and relatively long service life. Vibration level and choose a second semiconductor, crystal frequency: 32.768 KHz daily average poor: + 1 second/day, walking movement precision is high.
