The screw cover is
also called screw cover, which can effectively protect the screw, light bar, shaft, column and other parts from contamination and damage by dust and other things. It can expand or compress with the component. Or use it horizontally. It is recommended to use a plastic or aluminum support ring when horizontally used, to maintain a certain uniform distance between the inner cavity of the shroud and the screw rod to prolong the service life. When the stretch length is large, a metal ring can be added to each fold to improve the stability of the shield. The connection or fixed end usually uses a metal flange, or a ferrule can be selected.
Appearance: 1. Cylindrical. 2. Octagon. 3. Cone. 4. Polygon. 5. Square. 6. Oval material: Tri-proof cloth, frosted cloth, high temperature resistant cloth, special cloth, rubber cloth, special cloth, flame retardant cloth, asbestos cloth, canvas, black bright cloth, waterproof and oil proof cloth, etc.
Connection method: neckline butt joint, flange butt joint, collar neck butt joint flange can be divided into two forms according to the processing method, materials and processing factors:
One is a screw guard supported by a steel ring. This shield can use a variety of fabrics and is supported by a hard wire ring. It can work normally between minus 40 degrees Celsius and 110 degrees Celsius. Can effectively prevent dust, water, oil, anti-emulsions and chemicals. This shield has a neat shape and is not easy to deform. Based on its tightness and firmness, it can be used for ventilation and dust removal of many machinery. Its flexibility is not only in the choice of materials, but also in that it can determine the required diameter and length according to the specific requirements.
The other is the sewing screw cover. The circular screw cover is made of stamped discs. The two inner edges and the two outer edges are sewn together. It can be better by sewing. The shape is stable and firm in the horizontal direction. There are many choices of materials according to the working environment.
Features: completely leak-proof; can be bent arbitrarily; the diameter and length of the telescopic tube are not limited.
Generally, the ratio of the length of the sheath after stretching to the thickness of the sheath after shrinking is 100: 15, but it can also be processed to produce telescopic sheath products with larger or smaller ratios according to customer requirements.
Ordering requirements: shield inner diameter × outer diameter × stretched length × compressed thickness × material Note: 1. The user must provide the above data and selected material when ordering, and our company can design and manufacture it for you.
If the user has special requirements on the type of shield, our factory can negotiate with the user to design to meet the requirements
