 CZPT Design : ZB04   Haskel Ext420 CZPT pushed Refrigerant transfer/filling/recovery pressure Pump

 

CZPT air driven gasoline booster  pumps are ratio gadgets that employ minimal strain compressed

 

air driving a larger diameter piston (region x pressure) which is linearly related to a smaller sized

 

hydraulic piston/plunger. Using this ratio principal, a greater hydraulic pressure can be produced.

 

CZPT Pump model numbers replicate the pumps nominal force ratio, even though the specialized data 

 

suggests exact ratios.  The outlet stall stress is simple to established by modifying the air push strain

 

by way of a basic air strain regulator. By multiplying the strain ratio by the obtainable shop

 

air pressure, the nominal gas  stress can be calculated.

 

Example ( Pump Model: GBtwenty five Fuel booster pump)

 

Air push piston spot ( 160mm Ø)

 

CZPT plunger area (32mm Ø)

 

True ratio = 25:one

 

 1.  AIR Travel Segment

 

The air generate part is made up of a light bodyweight piston total with seals operating inside of 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 gasoline stop).

 

 Under the control of pilot pins (poppet valve) triggered at every finish of the stroke

 

two. GAS  Pushed Segment

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 verify valve

 

opens to the maximum enabling fuel into the fuel barrel and on the compression stroke

 

the inlet check out valve closes the discharge check valve opens forcing the pumped gas

 

 into the method  .The main high pressure seals is located on the gas piston and they seal agaist

 the gas barrel during operation . and the maximum pressures of the pump ,however the

 

CZPT PTFE seals are suitable for both the vast bulk 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 pushed gas boosters  that are not suitable for underground

coal mine apps .

CZPT Air pushed fuel boosters cycle routinely  as the outlet pressure 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   

Product variety for gasoline 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 next query is wheather you want the booster to stall when an outlet pressure is reached 

If so ,a easy airline force regulator will suffice ,but keep in mind the circulation drops off dramatically 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  .

 Remark 1) Maxium outlet stress are at an air driven force of 8 bar or 116 PSI ,for long life employing

of such pump ,we recommend that air pushed force should be not far more than 8 Bar  .
