Equipment enclosure: What is the necessity of installing protective covers for various mechanical equipment?
there are many kinds of protective sleeve. In the case of small space and no tight protection, the roller shutter protective cover can replace the elastic skin cavity protective cover. It can be installed and used horizontally, vertically or in any mixed direction. The transparent part is made of engineering plastic LEXAN resin, which has the function of anti-collision and anti-aging. Then the equipment cover: what is the necessity of installing protective covers for various mechanical equipment?
Equipment enclosure: What is the necessity of installing protective covers for various mechanical equipment?
In order to ensure the safety of mechanical equipment operators, various mechanical transmission belts, open gears, couplings close to the ground, pulleys, flywheels and other parts that are easy to harm the human body have perfect protective facilities. Therefore, the protective sleeve came into being.
1. Pulley: Pay attention to tightness when installing pulleys. If it is too tight, the belt will break, and if it is too loose, it will affect the normal rotation of the machine. There are two ways to protect the belt drive: one is to cover the belt with a protective cover; the other is to use a grating protection to prevent the human body from contacting the dangerous parts of the pulley when the belt is rotating.
2. Gear: In gear transmission, the danger is the meshing position of the gear and the gap between the gear spokes. In order to avoid the danger of gear transmission, install the protective cover, and all gears must be covered and closed. For the protection of gear transmission and friction wheel transmission, protection devices should be installed in the meshing area according to their characteristics. If possible, the gear should be installed in a completely enclosed machine base. The surface of the friction wheel is smooth and can only partially protect its contact parts, without overall protection.
3. Chain drive: The dangerous part of the chain drive is the place where the chain enters the sprocket. The chain drive system within 2 m from the ground and exposed outside the frame should have a protective cover.
4. Shaft: All accessories protruding from the shaft surface or not smooth, such as keys, fixing screws, etc. The exposed fixing screws are particularly harmful and may entangle people's clothes during production and cause injury. Therefore, install the protective cover. For the shaft within 2 m from the ground, except for the shaft placed inside the machine, all other exposed parts are covered with a protective cover.
5. Coupling: The risk of the coupling of the rotating shaft is basically similar to that of the shaft, but its severity is greater than that of the shaft, because the surface finish is worse than that of the shaft. The safety coupling shall have no protruding uneven parts, and the bolt head and nut shall be buried in the coupling, or the outer diameter edge of the coupling shall be designed to be larger than the bolt fastening size. In short, when the coupling rotates, there are protective measures such as baffle covers for parts that may be dangerous.
Equipment enclosure: What is the purpose of the elevator cover?
This is a protective cover designed for elevators, which has been hardened. The protective cover is welded with stainless steel and has the function of preventing prying. The incoming line is on the back of the protective cover and cannot be accessed by ordinary people. The windows are hard-wearing polycarbonate. The orientation of the camera is at a 45 angle to the car wall and a 45 angle to the ceiling plane. When the horizontal field of view exceeds 90 (wide angle), the whole vehicle can be observed without dead angle.
