In order to ensure the normal operation of the jaw crusher, in addition to the correct operation, planned maintenance must be carried out, including routine maintenance inspection, minor repair, medium repair and overhaul. (1) Minor repair: The main contents include inspection and repair adjustment device, high-speed discharge port clearance, turning or replacing the worn liner. Repair the transmission part, lubrication system and oil change. The minor repair cycle is about 1-3 months. (2) Medium repair: In addition to all the work of minor repairs, it also includes replacement of thrust plates, linings, inspection and repair of bearing bushes. The period of medium repair is generally about 1-2 years. (3) Overhaul: In addition to all the work in the middle repair, it also includes replacing or turning the eccentric shaft and the moving mandrel, casting the babbitt alloy on the upper part of the connecting rod head, and replacing or repairing the worn parts. The period of overhaul is generally about 5 years.
Precision Aspheric Lenses are designed to focus light while eliminating spherical aberration from divergent light sources in applications including focusing the output of a laser diode. Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.
Convex Aspheric elements are used to reduce aberrations, apheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
VIS coating option provides less than 1.5% reflection from 425 – 675nm. NIR coating option provides less than 1.5% reflection from 600 – 1050nm. Contact us for volume pricing of the custom aspheric lenses.
