Prevent people or objects from entering this dangerous area when the color steel tile machinery and equipment are running. The protective device should be easy to disassemble, and the protective device of the color steel tile mechanical equipment is usually prepared by the buyer. Therefore, this part of the content does not belong to the requirements for color steel tile machinery and equipment. The buyer or contractor shall specify the type of guarding required. Each color steel tile machinery and equipment should have protective devices to close the shaft. So that when the color steel tile mechanical equipment is overhauled and maintained, it will not affect the connected machines. The structure of the guard shall have sufficient rigidity, and its deflection shall not exceed 0.0005 times the unsupported length of the guard when subjected to a static load of 900N. The protective device of the color steel tile mechanical equipment that needs to be lubricated should be sealed. When necessary, the protective device should be equipped with an anti-movement baffle to reduce the influence of gas or oil. Flange-connected cylindrical shell guards are usually used in the middle and the structural cylindrical shape of the guards. One end of the guard shall have a telescopic joint
The head, the expansion joint is equipped with an O-ring seal. If the mechanical equipment of the color steel tile is under corrosive conditions and needs maintenance, the protective device must be equipped with a pipe joint to access dry air or inert gas. Guards for continuous lubrication of the controller. Each injector should be screwed to the guard in the proper direction so that the oil is sprayed in the direction of rotation. If the unit has forward and reverse operation, the oil is injected in the axial direction. The oil nozzle or oil pipe is not allowed to rub against the mechanical equipment of the color steel tile.
Conservative fix:
1. The positioning screws are used to fix the color steel tile mechanical equipment. The two positioning screws have a gap of 90o to lock the fixed shaft. Since the tip of the screw is in contact with the shaft, the shaft may be damaged or difficult to remove. shrink the slit;
2. The clamping screw is used to fix the color steel tile mechanical equipment using the tightening force of the inner hexagon bolt. And hold the shaft tightly. This method is convenient to fix and disassemble, and it will not cause damage to the shaft. It is a very common fixing method. To prevent axial sliding;
3. The keyway type fixed color steel tile mechanical equipment is suitable for high torque transmission. Usually used in combination with set screw and clamp screw. If the shaft of the motor is D-shaped;
4. D-shaped hole fixed color steel tile machinery and equipment: under normal circumstances. If the positioning screw cannot be fixed, the hole of the coupling can be disposed as a D-shaped hole corresponding to the size of the motor shaft, and fixed with the positioning screw, so there is no need to worry about slipping.
