Precautions when installing the pulley: 1, last cleaned before assembly must use petrol to ensure that all parts clean and dry, in order to ensure close cooperation with the surface and free of oil, there is enough friction. 2, prior to assembly with hex bolt assembly also use gasoline wash and dry, not the bolt or screw holes in the coating of oil or grease pulley manufacturers to ensure there is enough after friction bolts self-locking capability. 3, within three hex bolts fastening turns need to be installed in place in order to ensure a uniform axial force by the sleeve v-belt factory, ensure the pulley and sleeve coaxially positioned well. 4, pre-installation check the measurement assembly with hex bolt length to ensure that after the assembly bolt sleeve can withstand blind hole at the bottom, in order to ensure that the cone closely, and to ensure that the bottom of the blind hole bolt by wholesale reverse thrust cone Bushes, produce the same effect double locking nut principle. 5, after fastening the cable pulley to check and adjust the master, the relative position of the driven pulley, ensuring two rounds in the same plane and the belt tensioner moderate. 6, the pulley cover should be in good condition and securely installed to ensure operation in a broken belt or pulley loose exits lead to major accidents. 7, the sleeve are wearing parts, after a long run, the hole and chain groove damage that may occur, should be checked before each assembly, spare parts found defective should be replaced defective pulley pulley can ease automation components often used in automated production, operation seems very simple, but the automation program needs is fully automated to ensure efficiency continue, the flexibility to run, often driven pulley production automation program. Sometimes the size of the gap between the components fit, especially hoppers, due to the precision is not enough, most of the new moon in the inner wall of the liner plate, easily broken. Pump some machines did not even cross the bridge, even pulley mounted directly on the pump pulley, pump will soon pull the bad! If the position of the control valve is unreasonable, that will definitely increase the length of the pipeline, bringing increased costs, the use of the pulley can be well fixed position, ensuring automatic protection.
