Transmission lines hydraulic system

Selection and care of the hydraulic fluid for a machine will have an important effect on how it performs and on the life of the hydraulic components. During the design of equipment that requires fluid power, many factors are considered in selecting the type of system to be used-hydraulic, pneumatic, or a combination of the two. Some of the factors required are speed and accuracy of operation, surrounding atmospheric conditions, economic conditions, availability of replacement fluid, required pressure level, operating temperature range, contamination possibilities, cost of transmission lines, limitations of the equipment, lubricity, safety to the operators, and expected service life of the equipment. 

The components of a hydraulic system are similar to those of the pneumatic system. Figure 11-14 shows the components of a hydraulic system. The pressure of the hydraulic fluid is provided by the system s pump. The hydraulic pump is a device that creates flow in the system. The reservoir stores the hydraulic fluid before it is pressurized by the pump. Transmission lines carry the pressurized hydraulic fluid to the control valve and actuators. The control valves regulate the flow and pressure of the hydraulic fluid. The actuators transfer the fluid power into mechanical power. 

Uses and applications automotive fuel and powertrain systems, fuel lines, hydraulic hoses, transmission oil cooler hoses, servo brakes vacuum tubes, clutch tubes, and filaments. 

The PRSS is also used as an active reactor shutdown system. While the MCP continues to run, a scram signal can activate a motor driven valve to close the MCP delivery pressure transmission line and thus the hydraulic pressure valves open. In this case the poison is injected by forced circulation due to the MCP delivery pressure. 

Motors have many uses in fluid power systems. In hydraulic power drives, pumps and motors are combined with suitable lines and valves to form hydraulic transmissions. The pump commonly referred to as the A-end is driven by some outside source, such as an...
