CZPT Design :GB15 50-120 Bar output CZPT pushed CO2 fuel booster
pump for extraction tools
CZPT air driven fuel booster pumps are ratio products that use reduced stress compressed
air driving a bigger diameter piston (area x force) which is linearly related to a smaller
hydraulic piston/plunger. Using this ratio principal, a greater hydraulic stress can be produced.
CZPT Pump model figures mirror the pumps nominal force ratio, although the specialized data
implies exact ratios. The outlet stall force is straightforward to set by modifying the air generate force
by means of a simple air stress regulator. By multiplying the strain ratio by the obtainable store
air pressure, the nominal gas stress can be calculated.
Instance ( Pump Product: GB25 Gasoline booster pump)
Air drive piston location ( 160mm Ø)
CZPT plunger spot (32mm Ø)
Genuine ratio = 25:one
1. AIR Generate Section
The air drive area consists of a mild excess weight piston comprehensive with seals operating inside an
aluminum barrel. The diameter of the air piston is 160mm. When compressed air is provided to
the pump the air pushes the air piston down on a compression stroke
(forces as out of the gas finish).
Under the control of pilot pins (poppet valve) activated at each and every end of the stroke
2. GAS Pushed Area
The gas section of a CZPT air driven gas booster consisit of 4 main pieces
,the gas barrel ,the piston the check valves and the main high pressure seals .
The gaspiston is directly linked to the air piston and it is housedinside the gas barrel
and its movements up and down creates the gas flow into and out of the booster through
the check valves . The check valves are psring loaded and on the suction stroke .the inlet check out valve
opens to the greatest permitting gasoline into the gas barrel and on the compression stroke
the inlet check out valve closes the discharge check valve opens forcing the pumped gasoline
into the process .The main high pressure seals is located on the gas piston and they seal agaist
the gas barrel during operation . and the optimum pressures of the pump ,even so the
CZPT PTFE seals are suited for both the vast vast majority of gases encountered .
Other materials of construction can be supplied to meet more aggresive services
.The CZPT serials of booster are not suitable for underground coal mine applications .
CZPT DO CZPT models of air driven gas boosters that are not suitable for underground
coal mine purposes .
CZPT Air driven gas boosters cycle automatically as the outlet force increass the
resistance also increases and the cycle rate decreases until the pump stops automatically
when the out put pressure forces are equal .This is refered to as the stall condition .
The pump will restart with a slight drop in the outllet pressure or an increase in the air driven pressure
Booster performance can be affected by a number of conditions ,
such as freezing of the exhaust muffler or pilot valves ( Which is caused by moisture in
air lines ),inadequate inlet air line sizes and dirty filers .When operating the boosters
on a contunuous basis ,we recommend you use a maximum cycle rate of 50-60 cycles per minute .
This will both increase service intervals and assist in preventing ice forming at the exhaust .
An air supply dryer will also assist in reducing icing up .
CZPT Gas boosters have a 120mm stroke thus reducing cycle rates at any given flow
and pressure as compared with most other brands . This lower repsective cycle rate res
ults in a reduction in freeze-up condition .
To abtain best overall performance ,do not reduce the indicated port size and consult
CZPT for flow conditions not shown in charts
Model variety for gas booster
It is very important to remember that the performance of any air driven device is very dependent
on the air supply conditions .Restrictions in the air supply can be caused by using a too small air compressor or
airlines .The FLOW CHARTS SHOWN in the technical data sheet are based on good conditions .
so please do not “design to the line ” allow for losses and inefficiencies
The subsequent query is wheather you want the booster to stall when an outlet stress is reached
If so ,a basic airline strain regulator will suffice ,but bear in mind the flow drops off drastically as the
booster reaches a stall condition .
If you require flow at a particular pressure ,then you need read the flow cahrts carefully and conservatively
If you need the pump to stop at a certain pressure ,prior to stall ,then an air pilor switches needs to be installed .
