Special executions and complete systems

Special applications

As a natural consequence of competition in recent years it has been necessary for manufacturers to fulfil
customers requirements with special custom made products.
A.P.I. S.r.l., whose aim is to satisfy its customers and to improve its way of working, decided to pursue
this and to consider these special products as its strength from researching to machining, from mounting
to testing.

Complete systems

In order to achieve the aims mentioned above, A.P.I. S.r.l. are now in a position to manufacture complete
systems, such as control panels, to satisfy customer requirements, enabling the customer to achieve their
objectives.

Directive 2014/34/UE was made by the European Union to regulate the market of products used in potentially explosive atmo-
sphere, classifying technical characteristic and regulations.
Directive 2014/34/UE entered into force on 30 March 2014 and cancelled Directive 94/9/CE starting from 20 April 2016; this
impose ATEX certification to all the products sold in the European Community if installed in potentially explosive environments,
independently from the production seat and from the norms in force.

Group I:

equipment suitable to be used under-

ground in the mining sites and in their surface
plant.
(Category M1 and M2)

Group II:

equipment suitable to be used

in other sites which could be potentially
explosive.
(Category 1, 2, 3)

The products classified in the two groups can
have different protection ways against the
explosion, according to the zone where the
equipment is installed.

The cover of the equipment has not to have on the surface some flammable
points where spontaneous combustion can occur.
Different substances can flame at different temperatures. Less is the
flammable temperature, higher is the substance dangerous. For this reason
each equipment, used in an explosive environment, is classified according to
the maximum surface temperature it generates.
The maximum surface temperature must be always lower than the spontaneous
combustion temperature of powder and gas.

ATEX directive shows a classifications of gas and dust which could be potential-

product with suitable protection system.

With reference to the products of group II, the dangerous of gas and dust

covered by the products increase in IIA a and IIIA category the less dangerous
to IIC and IIC the most dangerous.

To determinate the gas and the dust potentially present and the relative sharing,
please check the table for group II.

General technical information

PHYSICAL MAGNITUDES AND DATA

The pneumatic components use compressed air. Pressure is a force that is applied per unit of area. The pressure that can be measured with the
special instrument - the manometer - is called manometric or relative to the atmospheric pressure in which the instrument is emerged. Absolute
pressure is obtained by adding atmospheric pressure to the manometric pressure.

UNITS OF MEASUREMENT - INTERNATIONAL SYSTEM (SI)

The SI units have been introduced in the majority of countries on the basis of international conventions.
The aim is to achieve sole

UNITS OF MEASUREMENT

in order to avoid the difficult conversions from one system of measurement to another.

The

SI SYSTEM

considers seven fundamental physical magnitudes with their respective units of measurement. All the other units of

measurement are derived from these.
The fundamental units are:
Length in metres [ m ], mass in kilograms [ Kg ], time in seconds [ s ], electrical current in amperes [ A ], temperature in degrees Kelvin [ °K ],
molecular quantity in moles [ mol ], luminous intensity in candelas [ cd ].
Forces are derived magnitudes and are expressed in Newtons [ N ].
According to the fundamental law of dynamics, one Newton is the force required to accelerate a mass of 1 Kg
1 m/s

As 1 Kp is the force required to give a mass of 1 Kg the acceleration of gravity, which is equivalent to 9.81 m/s

, it follows that 1 Kp = 9.81

N = approx. 10 N. Indeed, the latter value is assumed in order to avoid an excessive precision of calculation.
Pressure is thus measured in N/m

, a unit known as the Pascal [ Pa ]. The unit of measurement that is equivalent to 100x103 Pa [ bar ] is still

accepted. We can write 1 bar = 100 KPa.

General technical information

VOLUME IN NORMAL CONDITIONS

The following are considered normal conditions of the fluid: temperature °K = 273 + 20 °C, pressure = 1 bar.
For the following considerations, the equation of state of perfect gases is also accepted as valid for the actual air gas.
This is: PV = nRT where

P = absolute pressure of the gas [ bar ]

V = volume [ m

]

T = absolute temperature [°K ]

Imagine that we wish to bring a given volume of air V1, subject to pressure P1 and temperature T1 back to the normal conditions P0, V0, T0.
We can say that the situation will pass from P1V1 = nRT1 to P0V0 = nRT0.
Therefore, P1V1/T1 = P0V0/T0, from which it follows that:
V0 = V1x(P1/P0)x(T0/T1).
In normal conditions volume is directly proportional to the relationship of the pressure values and inversely to that of the temperature values.
As the latter are expressed as 273 + °C, the influence of their relationship is negligible, consequently we normally consider:
V0 = (P1/P0)x V1 [ Nm

Cylinders

Technical data

The pneumatic cylinder is an engine that uses pneumatic energy, transforming it into mechanical work by means of rectilinear
movement.
It is composed of a tube, closed at the ends by two heads, within which a piston moves, separating two chambers. The piston
is equipped with a rod that, when exiting through one or both of the heads, permits the exploitation of the force developed
by the cylinder.
The characteristic parameters of a cylinder are:
Bore

= internal diameter of the tube [ mm ].

Stroke

= working movement to be performed [ mm ].

Diameter of piston rod = closely correlated to the bore [ mm ].
Number of actings

= number of strokes per cycle during which work is performed. These may be either one

(single acting); or two (double acting).

Operating pressure [ 1 bar ].
Operating temperature [ °C ].
Translation velocity [m/s].
Number of adjustable end cushionings.
Kinetic energy absorbed by the cushionings [Nm].
Air consumption [ nl/min ].
Theoretical force Ft [ N ]

BORE Ø

A finite number of bores are available, all of which are standardized. The range goes from bores measuring just a few milli-
metres to those of 300 mm.

PRESSURE p

This value is not very variable, due to technical-economical reasons. It covers the range 5-7 bar. A system operating at 6
bar is considered optimized.

PISTON ROD DIAMETER d

This is standardized for all the bores available.

STROKE c

The most frequently requested strokes are available in our warehouse. Any technically compatible stroke can be supplied in
a short time. It is advisable to choose easily available strokes that are greater than the operating strokes, halting the stoke
at the desired value by means of external mechanical stops, in order to obtain mechanical precision and greater durability
of the cylinder.

OPERATING TEMPERATURE

Ambient temperature must not be such as to make the cylinder assume values outside the temperature range for which it
was constructed. It is possible to construct cylinders that are resistant to very low or very high temperatures, using special
materials.
The catalogues always show the operating temperature range.
The cylinder can also reach high temperatures due to particular conditions of use: in general, when the friction between
the tube and the mobile apparatus increases greatly (e.g. due to high speeds with insufficient lubrication, the exhaustion of
assembly lubrication or excessive compression of the air). The seals of the cylinder are the most short-lived component and
those that are most sensitive to temperature.

TRANSLATION VELOCITY v

It is advisable to adjust the translation velocity by means of the air discharge.
The movement of the piston is fairly regular even with minimum velocities of 40 mm/s.
The maximum velocity acceptable without additional lubrication to assembly lubrication, is equivalent to 1000 mm/s.
Velocities of 2 ÷ 3 m/s can be reached with appropriate lubrication.
For high velocities, as for high masses, the kinetic energy to be reabsorbed is excessive for the air cushionings. It is nec-
essary to use external hydraulic cushionings of an appropriate size.
