Fan Belt Tensioner 2891940 Parameter:
1. The tensioner acts on the timing belt or timing chain of the engine to guide and tighten it, so that it is always in a good tension state. Generally divided into two methods: hydraulic and mechanical, both of which can automatically adjust the tension of the timing belt and timing chain. Under the drive of the timing belt or timing chain, the camshaft drives the valve to open and close at the correct time, and cooperates with the piston to complete the four processes of intake, compression, power and exhaust.
2. The tensioner provides pressure directed at the belt or chain, the tensioner pulleys are in direct contact with the timing belt, and the guide rails are in direct contact with the timing chain, and they run with the belt or chain while applying the tensioner-provided pressure to it , so that they maintain the appropriate degree of tension.
3. Application for Heavy duty truck, buses, engineering machinery, mining machinery, petroleum machinery, railway machinery, port machinery, stationary and mobile diesel generator set power stations, Marine propulsion unit and auxiliary power unit, pump power units and other power units, automobile industry power ships.
