Correct belt alignment, fitting and tension ensures proper system performance, long belt and bearing life expectancy and reduced energy costs. The new belts should be placed over the pulleys and not "Run On". Run on is a term used when belts are forced onto pulleys under tension over the grooves, this causes damage to the belts.
The correct tension of a V-belt drive is the lowest tension at which the belt will not slip at peak load conditions. It is advisable to wear gloves when handling pulleys and belts to reduce the risk of injury to your hands, equally important is correct work wear with no loose clothing which may get caught in the equipment. For installations without a variable speed drive (direct online or star delta starters), the belt must be tensioned to handle increased motor torque during startup. There are many factors involved in calculating the correct tension for a given belt, the speed it will operate at, the smallest pulley it will run around, the span length of the belt, it's operating temperature etc.The pulleys should be inspected for wear or damage and replaced as deemed necessary, badly worn pulleys will cause premature failure of the new belts. Over tensioned belts stretch excessively and also generate heat, which reduces belt and bearing life, and increases energy costs as system loads increase. High Permeability: Our heavy duty weed barrier is designed with excellent permeability. You never need to worry about the water will be puddled on the top of the material. In addition, the sturdy structure of the fabric stops weed or grass from going through, effectively inhibiting weed or grass growth. The following are generic approximations of the required forces to achieve the correct tensions. Please refer to the original manufacturers manual for the actually required belt tension for your equipment. For slow start variable frequency drive applications (inverter drives), the belt must be tensioned to handle the actual brake horsepower of the driving force.
Clean any debris from the grooves of the pulley, rubber deposits can be cleared with a wire brush etc.Durable PP Fabric: This 2.4 oz landscape weed barrier fabric measures 6 ft wide and 300 ft long. The heavy duty weed barrier is here to fully cover 1800 sq. ft area, making your life easier and 100% hassle-free. It protects your garden and flower beds from weeds, highly increasing your productivity and efficiency. Belts should be stored flat and not hung up, they are best stored in a cool dry place away from direct sunlight. For your safety and that of others around you, before commencing work on any drive please be sure to isolate all sources of power to the installation, electrical, engines, mechanical, water power, wind and stored energy sources such that systems with cams or springs may have. Easy Installation: Our garden cloth weed barrier is effortless to cut and install. It is convenient to DIY the cloth size and shape to meet your different needs. The garden weed cloth also features green stripes for easy plant alignment. (Installation tools are not included.) As a general rule of thumb, we should be looking for 1/64 inch deflection per span inch length or 0.0156mm per span mm length.
