Pressure and temperature in the system to determine the type of hose used. Keep in mind that the size of the hose should really be in accordance with the requirements of flow in the system. Hose is too small limited; flow, causing excessive heat and pressure losses.
However, too large diameter hose used pressure system becomes too weak. This is because the larger hose should be stronger against the same pressure as in the small hose. Also, it is too big Harganyapun expensive. One more factor to consider is the suitability of the material hose to fluid flow.
Hydraulic hoses for classified and determined by the strength of the wall construction. There are four commonly used types of hoses paqa hydraulic system, namely:
1. Woven loom
2. Matting single wire
3. Woven double wire
4. The spiral wire.
At the drain hose higher fluid pressure using a more resilient reinforcing layer (stronger) or extra layers (see Figure 3.94).
However a pressure hose hose will take varying sizes. Larger hose less against pressure when compared with the smaller on the same construction. This is because having a larger cross-sectional area exposed to pressure.
Grades are based on a pressure hose system working pressure. It must be able to withstand the maximum pressure peaks during normal system operation. Hydraulic oil temperature should also be considered in the selection of the hose. Four types of hose as a whole will perform work (operations) on a normal hot, but there are also hoses designed specifically for the purpose of extra high temperature.
