Q

The primary function of a hydraulic fluid is to transmit efficiently the blank and blank applied at one point in the system to the point where they required mechanical action is produced

A

Force and energy

19
Q

Before filling a system take precautionary steps to ensure the blank before installing the new fluid

A

Cleanliness of the system

20
Q

How often you inspect, what you inspect, and what you inspect for depend on what

A

Type of system

21
Q

Many companies find it best to completely recondition a system blank when it has run for two or more years or when it

A

Periodically and breakdown

22
Q

When should you check and service hydraulic fluid

A

Every 1000 hours for contact to be sent for lab analysis

23
Q

When working on hydraulic systems personal blank should never be sacrificed for production

A

Safety

24
Q

One of the first things to do when the hydraulic system breaks down used to study the most recent history of its operation and performance the second step is to evaluate the symptoms to determine the blank of the present malfunction

A

Cause

25
Q

Gauges are also equipped with the bases called blank which keep the needle from fluttering and absorb surges of pressure to protect the gauges

A

Snubbers

26
Q

Flow meters are used for blank and monitoring purposes

A

Testing

27
Q

The first step is to take out the blank blank for that machine and learn some thing about its operation

A

Maintenance folder

28
Q

How do you determine a valve is bad

A

Test the circuit

29
Q

Misalignment created by excessive blank blank causes the cylinder to bind and become inop

A

Sideloading

30
Q

If the metering orifice is blocked or restricted, the fluid will not be allowed to pass freely through the valve, and the cylinder will not move or will move very slowly, what type of valve is this

A

Speed control valve

31
Q

Fire resistant fluids the most popular types are water base fluids, emulsion fluids, and phosphate ester fluids

A

All the above

32
Q

When installing a new cylinder do this before you connect the cylinder

A

Blow the pipe and fittings clean

33
Q

Why is it difficult to troubleshoot a hydraulic pump or motor in service

A

Visual inspection’s water pump is an operation on limited because it is covered

34
Q

What may cause other failures such as a fractured pressure ring

A

Pressure shocks

35
Q

Excessive wear scratches or roughness mean that blank blank have been introduced into the pump

A

Solid contaminants

36
Q

If contaminants are allowed to get into the pump their presents shows up very quickly because of why

A

Close tolerance between pump parts

37
Q

When any type of gear pump all motor is being repaired it is a good general practice to replace what

A

Anti-friction bearings, shaft seals, and gaskets

38
Q

Wear in a vane pump can be reduced to a minimum by using the proper

A

Fluid

39
Q

In a variable displacement pump the circular ring movement is controlled by a pressure

A

Compensator

40
Q

When it reinstalling sleeve bearings be sure to line up to lubrication

A

Grooves or slots

41
Q

Name the two types of vein pumps

A

Constant displacement, variable displacement

42
Q

The only control used with a constant displacement gear pump is an occasional

A

Relief valve

43
Q

A variable displacement pump does not require a relief valve because the pump can

A

Shift to a no flow position

44
Q

When troubleshooting a hydraulic pump, which of the following should you do last

A

Disassemble the pump and inspect the components
