Hydraulics week 6

A _____ Stores hydraulic energy.

• Diverter Valve

• Accumulator

• Reservoir

• Rectifier

• Capacitor

Accumulators Come in two types:

• Gas Charged and Spring Charged

• Sprung and Un-Sprung

• Aspirated and Sealed

• Vented and Non-Vented

_____ is the formation of gas bubbles at the inlet of the pump due to low inlet pressure.

• Brinelling

• Buelling

• Aeration

• Cavitation

• Aerocorrosion

________ is the most common cause of pump failure

• Heart Disease

• Contaminated Fluid

• Stripped Gears

• Humidity

• Speed

________ Are used to prevent flow in one direction but allow free flow in the opposite direction.

• Needle Valves

• Check Valves

• Directional Control Valves

• Accumulators

• Rectifiers

An indication of pump cavitation :

• Dry Rotted Hoses

• Milky Hydraulic Fluid

• Brown Discharge

• Excessive Pump Noise

• Meth Mouth

Hydraulic Fluid can be purged of water contamination by using a:

• Vacuum Pump

• Pneumatic Injection

• Chemical Additive

• Heat Gun

• Condenser

Adjustable flow-control valve that oil must make a right turn through valve.

• Needle Valve

• Globe Valve

• Gate Valve

• Schrader Valve

• Pressure Compensating Valve

Ensure primary circuit has needs met first before supplying secondary circuit.

• Diverter Valve

• Compensating Valve

• Priority Valve

• Levelling valve

• Summing Valve

Senses differential pressure and blocks off circuit’s flow.

• Proximity Diverter

• Pilot Fuse

• Summation Block

• Allstop Valve

• Velocity Fuse
