11Hydraulic machinery — are machines and tools which use fluid power to do work. Heavy equipment is a common example.In this type of machine, high pressure hydraulic fluid is transmitted throughout the machine to various hydraulic motors and hydraulic cylinders. The… …
12Hydraulic fluid — Hydraulic fluids are a large group of fluids used as the motive medium in hydraulic machinery. Fluid types include synthetic compounds, mineral oil, water, and water based mixtures. The fluids are found in machinery and equipment ranging from… …
13Control valves — are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a setpoint to a process variable whose value is… …
14Hydraulic empire — A hydraulic empire, also known as a hydraulic despotism or water monopoly empire , is a social or government structure which maintains power and control through exclusive control over access to water. It arises through the need for flood control… …
15Hydraulic jump — A hydraulic jump is a phenomenon in the science of hydraulics which is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise (a step or… …
16Hydraulic drive system — A hydraulic or hydrostatic drive system or hydraulic power transmission is a drive or transmission system that makes use of a hydraulic fluid under pressure to drive machinery.Such a system basically consists of: *Generator part of the… …
17Hydraulic hooklift hoist — PRESSURE FLOW Hydraulic Oil Pressure = Capacity All hooklift hoists are preset, at the factory, to achieve intended lifting capacity. Turning up the system s pressure will increase lifting capacity, but adjusting or tampering with hoist s… …
18Hydraulic fill — A hydraulic fill is an embankment or other fill in which the materials are deposited in place by a flowing stream of water, with the deposition being selective. Gravity, coupled with velocity control, is used to effect the selected deposition of… …
19Control system — For other uses, see Control system (disambiguation). A control system is a device, or set of devices to manage, command, direct or regulate the behavior of other devices or system. There are two common classes of control systems, with many… …
20Hydraulic cylinder — A Hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a linear force through a linear stroke. It has many applications, notably in engineering vehicles. Operation Hydraulic cylinders get their… …
