When using the screw cover horizontally, it is recommended to use a plastic or aluminum support ring to maintain a certain uniform distance between the interior of the cover and the screw, extending its service life. For larger stretch lengths, add a metal ring at each fold to enhance the stability of the cover. The connection or fixing end is usually done with a metal flange disk, or a sleeve clamp can also be chosen.
Screw jack guards can be divided into two types, based on the manufacturing process and considering the suitability of different materials for various processing techniques.
A steel ring-supported screw cover, which is made of various fabrics, featuring a sturdy steel wire ring for support and capable of operating normally between high temperatures of 110℃ and low temperatures of -40℃. It effectively prevents dust, water, oil, emulsions, and chemicals. The cover is neatly shaped and resists deformation. Due to its tightness and rigidity, this cover is suitable for ventilation and dust removal in various machinery. The flexibility of this product not only lies in the choice of materials but also in its ability to determine the required diameter and length based on specific requirements.
Another option is the sewing screw cover, which is made by sewing a stamped circular disc. The two inner edges and two outer edges are stitched together, providing good shape stability and firmness in the horizontal direction. Materials can vary according to the working environment, including rubber-coated fabric, oil-resistant fabric, waterproof fabric, flame-retardant fabric, acid and alkali-resistant fabric, asbestos fabric, and fire-resistant fabric, offering a range of choices.
