Tips: Diaphragm coupling application

Diaphragm couplings are widely used in shaft transmission of various mechanical devices, such as water pumps (especially high-power, chemical pumps), fans, compressors, hydraulic machinery, petroleum machinery, printing machinery, textile machinery, chemical machinery, mining Machinery, metallurgical machinery, aviation (helicopter), naval high-speed power transmission systems, steam turbines, piston-type power mechanical transmission systems, crawler vehicles, and generator sets high-speed, high-power mechanical transmission systems, which are applied to high-speed transmission after dynamic balance shafting.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
