Hydarulic filters: In hydraulic systems, they filter the hydraulic liquid before directing that liquid to the hydarulic system compartments.
Hydarulic cooler: They are fan or pump systems to cool the hydraulic systems that gets hot. They generally use water or air.
Hydraulic Pipes: Pipes in hydraulic systems to transfer the hydraulic fluid between the different systems of the hydraulic parts. They are geneerally resistant to high pressures and flexible for the motions of the actuators.
Head pressure: The total pressure that required to send an amount of water to a specific elevation in pump systems.
Hydraulic reservoir: In hydraulic systems, they are the resevoirs that hydraulic fluid circulates. Pump take hydraulic fluid and pumps to the other systems. And the excess fluid comes to the reservoir again.
Health and Safety at Work Act: The Health and Safety at Work etc. Act 1974 is an Act of the Parliament of the United Kingdom that as of 2011 defines the fundamental structure and authority for the encouragement, regulation and enforcement of workplace health, safety and welfare within the United Kingdom.
Health & safety executive: In different companies and work places, the executive officers that are responsible of occupational health and safety rule applications. Or they are at the head of these departments.
Health & safety commission: Governmental or state commisions that built for the auditing the general occupational safety rules for work places and factories.
Hydarulic heat exchanger: In hydraulic systems, they are the heat exchangers that used for the cooling of the hydraulic fluid running through the system. They use water or air as cooling fluid.
High water content fluids: Fluids that have very big water contents in them.
Horsepower: Horsepower is the power measurement unit which has fps or ft.lb/s unit. In SI units, 1 horsepower is equal to 745.7 Watts.
Hydarulic hoses: Flexible and durable hoses that they use in hydraulic systems to transfer high pressure hydraulic fluid between the hydraulic fluid containers and the actuators.
HSE: It is the acronym of the Health, Safety and Environment.
Humidity: Humidituy is the percent of water vapor in the air or environment. With the 100% humidity, condensation takes place. For example, in the atmosphere, if the humidity reaches to 100%, it rains.
Hydraulic filters: Filters in hydraulic systems that filters the possible pollutants and contaminants in hydraulic flluids.
Hydraulic fluids: General fluids that they use in the pressure transfer in the hydraulic systems.
Hydrodynamic devices: Hydrodynamic devices are th edevices that works with the fluid flow and other action of fluids. For example, pumps, compressors and turbines are the hydrodynamic devices.
Hydrostatic pump: Hydrostatic pumps are the devices to test the pressures of the flowing or static fluids. They can measure pressures up to 10.000 psi.
Hydarulic tanks: Tanks in hydraulic systems that contains hydraulic fluid inside it.
Hybrid material: They are the types of composite materials that composed of two or more different composite fibres.
Hydrokinetic torque converter: They are the devices in automotive systems that converts and transfers the torque by using the wall friction of the fluid inside these systems.
Hydraulic transmission: They are the types of transmissions that a pump converts the rotational mechanical energy into a fluid pressure, and the motor reconverts this pressure into a mechanical energy.
