Vocabulary B Flashcards
1) Inner Liner:
Carries the fluid and, therefore, must have a minimum porosity and be chemically compatible with the material being carried.
Ref-10-17,p3
Lay Line:
A mark on almost all flexible hoses outer cover, it consists of a yellow, red, or white stripe running the length of the hose.
Ref-10-15,p3
Skydrol:
A synthetic, non-flammable, ester-based hydraulic fluid, used in modern high-temperature hydraulic systems.
Ref. Av. Dicc. P#287
4) Heat Shrink:
An abrasion sleeve used to protect the fluid line when it rubes against an other part.
Ref. 10-20,p2
5) Swaged on fitting:
A type of fitting assembled on special machinery that si typically not found in the shop. These fittings cannot be removed and reused.
Ref. 10-16,p6
7) Socket:
In Fluids, Lines & Fittings, Sockets are 1 out of 3 parts connection set used to join 2 tube lines together.
Ref. Fig.#10-34
8) Spiral wrap:
A protective sleeve used on fluid lines.
Ref. 10-20,p2
9) Flexible hose:
They are designed to connect stationary parts to moving parts, they consist of inner liner covered with layers of reinforcement to provide strength, and an outer cover to protect from physical damage.
Ref. 10-14,p2
10) Neoprene:
A form of synthetic rubber that is abrasion resistant and used with petroleum-based products.
Ref. 10-14,p4
11) Buna-N:
A synthetic rubber compound that is better suited than Neoprene, also used to carry petroleum-based products.
Ref. 10-14,p5
12) Mineral-based fluid:
A petroleum-based hydraulic fluid consisting essentially of kerosene and additives to inhibit corrosion and minimize foaming. It dies red, identified as MIL-H-5606.
Ref. Av. Dicc. P205
13) Butyl:
A synthetic rubber product made by the polymerization of isobutylene. It withstands such potent chemicals as skydrol hydraulic fluid.
14) Teflon:
A fluorocarbon resin used to make hydraulic and pneumatic seals and backup rings.
15) Reinforcement Layer:
It is placed over an inner liner, it determines the strength of the hose. Commonly made of cotton.
Ref. 10-14,p6
16) Outer Layer:
On flexible hoses. It is the outer cover to protect from physical damage.
Ref. 10-14,P2
17) MIL-SPEC:
Term used to identify military specifications.
Ref. Av. Dicc. P205
18) Low Pressure Hose:
These hoses have a seamless inner tube and a reinforcement made out of a single layer of cotton braid.
They are used on most vacuum hoses and aircraft instruments.
Ref. 10-16,P5
19) Medium-Pressure hose:
These hoses are used with Fluid pressure up to 3,000 psi, their maximum operating pressure varies with their diameter.
Ref. 10-16,P6
20) High-Pressure Hose:
These have a maximum operating pressure of at least 3000 psi, and use a synthetic rubber liner to carrie petroleum products.
Ref. 10-16,p1
21) Phosphate Ester Base:
A synthetic hydraulic fluid, fire-resistant, used in high pressure hydroelectric systems of modern jet aircraft.
Identified by the specification MIL-H-8446.
22) Size Designation:
Dimensions taken to denote tubing sizing. The size of a Rigid tubing is determined by outside diameter in increments of 1/16 inches.
Ref. 10-3,p3
23) ID:
A size designation taken from the inside surface of the tube. It is determined by subtracting twice the wall thickness from the outside diameter.
24) O.D:
Outside diameter , a size designation taken around the outside surface of the tube, typically printed on all Rigid tubing.
Ref. 10-3,p3
25) Wall Thickness:
A size designation that determines a tube’s strength.
10-3,p4
