Hydraulic Hose Filter System Design
The hydraulic hose must match the highest pressure capable in the hydraulic filters system, which is usually the pressure given by the pump. However, of course there is a component of increased pressure on the engine that can be much higher than hydraulic reliefs or pump pressure capacity, especially when the cylinder intensifies the pressure produced. Special attention must apply when designing a system with a flow divider because of this effect. Hose usually has a rating of burst 4 times the pressure rating so that even though the lower ranking can work for a short time, they will be exhausted and then fail in a shorter time. A good idea to then see a failed hose to ensure it will match the pressure ranking of the hydraulic flow circuit. Sometimes people can easily make hydraulic hose assemblies from the wrong type of hose and will not realize it only to failure. This can happen even from the factory. High pressure hydraulic lines for cellular equipment usually come in some amount o...
