Product Description
Screw shield is a shield, also known as screw shields, it can effectively protect the screw, light bars, shafts, columns and other parts from dust loaded with special pollution and destruction, it is possible to do with the components stretch or compression movement, vertical or horizontal use can be. Level is recommended when using plastic or aluminum support ring, holding shield a certain uniform distance between the cavity and the screw, and prolong life. Stretching the length of time you can add a large metal ring at each compromise, to improve the stability of the shroud. Connection or fixed end commonly used metal flange can also choose cuff style.
Screw shields by processing methods, while also taking into account the different materials suitable for different process can be divided into two forms.
One is the steel ring supported screw shields, this shield using a variety of fabrics, there are stiff wire ring support in high temperature 110 ºC, work among low-temperature -40 ºC. Can effectively dust, water, oil, anti-emulsion and chemicals, appearance neat, easy to distort, based on its tight, strong, this shield and can be used in many mechanical ventilation, dust and the like. This product is not only flexible materials available, but also because of the specific requirements it can be determined according to the desired diameter and length.
Another is sewing screw shields, circular screw shields are stamped by the disc sewn into, within two adjacent sides, two outside stitched together by sewing can achieve better stable and robust shape in the horizontal direction. Material according to different working environment echoed rubber cloth, anti-tarpaulin, tarpaulins, flame retardant cloth, acid cloth, asbestos cloth, fireproof choices.
