CZPT Data for Air driven liquid pumps
CZPT air pushed liquid pumps are ratio products that make use of reduced pressure compressed
air driving a larger diameter piston (location x force) which is linearly linked to a smaller
hydraulic piston/plunger. Making use of this ratio principal, a increased hydraulic pressure can be created.
CZPT Pump product quantities replicate the pumps nominal force ratio, even though the specialized data
indicates precise ratios. The outlet stall force is straightforward to set by altering the air drive stress
by means of a easy air stress regulator.
By multiplying the force ratio by the accessible shop
air pressure, the nominal liquid force can be calculated.
Exmple ( Pump Model: AT644 liquid pump)
Air travel piston region ( 160mm Ø)
CZPT plunger region ( 20 mm Ø)
Actual ratio = 64:1
one. AIR Push Part
The air drive segment is composed of a light bodyweight piston complete with seals working within an
aluminum barrel. The diameter of the air piston is 80mm. When compressed air is supplied to
the pump the air pushes the air piston down on a compression stroke
( forces fluid out of the liquid finish).
Under the control of pilot pins (poppet valve) activated at every single stop of the stroke
two. CZPT Area (Wetted End)
The hydraulic area of an air pushed liquid pump consists of four primary items, the hydraulic body,
the piston/plunger, the check valves and the principal high force seal. The hydraulic
piston/plunger is directly linked to the air piston and it is housed within the hydraulic entire body and
its movement up and down results in the liquid movement into and out of the pump via the check
valves. The examine valves are spring loaded and on the suction stroke the inlet check valve
opens to the highest enabling fluid into the hydraulic physique and on the compression stroke the
inlet verify valve closes and the discharge check valve opens forcing the pumped fluid into the
approach. The primary substantial pressure seal is located in the hydraulic body and the piston/plunger seals
against this throughout operation. There are diverse supplies and designs of high strain seals
based on the fluid getting pumped and the optimum pressures of the pump, nonetheless the
CZPT seals are suitable for each drinking water and hydraulic fluid use.
CZPT air driven liquid pumps are self-priming, However, large ratio pumps are much more difficult to
Prime and may call for bleeding. In general, it is not advisable to use an air- line lubricator.
CZPT air pushed liquid pumps cycle automatically as the outlet stress increases the
resistance also increases and the cycle rate decreases until finally the pump stops instantly
when the output pressure forces are equivalent. This is referred to as the stall problem.
The pump will restart with a slight drop in the outlet strain or an improve in the air push
force. Pump performance can be affected by a quantity of situations, these kinds of as freezing of the
exhaust muffler or pilot valves (which is brought on by moisture in air lines), insufficient inlet air-line
sizes and dirty filers. When functioning the pumps on a constant foundation, we recommend you use
a greatest cycle price of 50~60 cycles for every minute.
This will both improve support intervals and help in stopping ice forming
at the exhaust. An air source dryer will also support in reducing icing up.
To acquire greatest all round efficiency, it is suggested not to decrease the indicated port measurements
and consult We for movement circumstances not revealed in charts.
