The document discusses hydraulic systems used in construction equipment. It focuses on load sensing (LS) valves and pressure compensated (PC) valves that are used to control hydraulic pump discharge based on system pressures. The LS valve monitors differential pressure between the pump and workport to regulate pump flow, increasing it under load and decreasing it otherwise. The PC valve works to maintain equal power by reducing pump discharge if pressure rises too much. Diagrams show how these valves interface with hydraulic pumps and solenoids to optimize pump output based on changing load conditions.

Excellent paper on cavitation in control valves by Samson. Read this for a strong technical understanding of the cause and effects of cavitation and flashing on industrial control valves.
Cavitation shall be generally understood as the dynamic process of the formation and implosion of cavities in fluids.Cavitation occurs, for instance, when high flow velocities cause the local hydrostatic pressure to drop to a critical value which roughly corresponds to the vapor pressure of the fluid. This causes small bubbles filled with steam and gases to form. These bubbles finally collapse when they reach the high-pressure areas as they are carried along by the liquid flow. In the final phase of bubble implosion, high pressure peaks are generated inside the bubbles and in their immediate surroundings. These pressure peaks lead to mechanical vibrations, noise and material erosion of surfaces in walled areas. If cavitation is severe, the hydraulic valve coefficients as well as the fluid properties change.
A hydraulic accumulator is a device that stores pressurized liquid energy for sudden energy requirements. It stores hydraulic energy in the form of pressure that can be used, for example, when a lift or crane is moving upward. The accumulator's capacity is the maximum amount of hydraulic energy it can store, which is calculated as the product of the pressure supplied by the pump, the area of the sliding ram, and the stroke or lift of the ram.
Accumulators store hydraulic energy and make it available on demand to hydraulic systems. They are suitable for hydraulic shock suppression, eliminating pressure ripple, fluid make up in closed circuits, leakage compensation, and providing emergency power during power failures or for holding high pressure without the pump running. Accumulators are often used for flow compensation to meet additional hydraulic demands beyond the pump output, maintaining specific pressures during machine cycles, compensating for energy losses due to leakage or pressure drops, and suppressing shocks in high pressure systems. The type of accumulator chosen depends on factors like mounting position, temperature requirements, and failure risk.
The hydraulic accumulator stores energy from liquid pressure by using a sliding ram inside a chamber. The accumulator's capacity, or maximum stored energy, is calculated as the product of the pressure supplied to the pump, the area of the ram, and the stroke or lift of the ram. By lifting the ram, pressure energy is stored equal to the pressure times the volume of the accumulator chamber. The accumulator allows this pressure energy to be released later to power hydraulic systems.
Hydraulic machines are nothing without their hydraulic pumps. In this webinar, Josh Cosford describe the basic operation of a hydraulic pump. Josh describes the various types of hydraulic pumps available, as well as the merits and disadvantages to each design.
The document provides an overview of industrial hydraulics, including:
- The definition and etymology of hydraulics.
- Examples of hydraulics in everyday life and basic hydraulic systems like hydraulic jacks.
- Key figures in the development of hydraulics like Joseph Bramah.
- Fundamental hydraulic principles like Pascal's law.
- Components of hydraulic systems like pumps, valves, actuators, and fluid conditioning elements.
- Types of hydraulic pumps, cylinders, motors, and directional control valves.
Hydraulic Design of Sewer:
Hydraulic formulae, maximum and minimum velocities in sewer, hydraulic
characteristics of circular sewer in running full and partial full conditions,
laying and testing of sewer, sewer appurtenances and network.
The document provides information about pumps, including:
1) Pumps are mechanical devices that use rotation or reciprocation to move fluid from one place to another by converting energy into hydraulic energy.
2) The main purposes of pumps are to transfer fluid from low to high pressure areas, from low to high elevations, and from local to distant locations.
3) There are two main types of pumps - positive displacement pumps which move a fixed volume of fluid with each cycle, and centrifugal pumps which use centrifugal force to move fluid by spinning an impeller.

1. Hydraulic actuators convert hydraulic energy into mechanical motion or force.
2. There are two main types of hydraulic actuators: linear actuators, which produce linear motion, and rotary actuators, which produce rotary motion.
3. Common types of linear actuators include single acting cylinders, double acting cylinders, and double rod cylinders, while common rotary actuators include rotary vane actuators and single/double cylinder rack and pinion actuators.
