CZPT Design : WB06   air driven refrigerant booster pump

for R22,R134,R407C,r410A

 

CZPT air pushed fuel booster  pumps are ratio devices that utilize low strain compressed

 

air driving a greater diameter piston (location x stress) which is linearly related to a more compact

 

hydraulic piston/plunger. Employing this ratio principal, a higher hydraulic force can be generated.

 

CZPT Pump design numbers replicate the pumps nominal pressure ratio, although the specialized data 

 

signifies actual ratios.  The outlet stall stress is effortless to set by changing the air generate strain

 

through a straightforward air pressure regulator. By multiplying the pressure ratio by the available store

 

air pressure, the nominal gas  strain can be calculated.

 one.  AIR Generate Part

 

The air drive area is made up of a light-weight excess weight piston full with seals working within an

 

aluminum barrel. The diameter of the air piston is 160mm. When compressed air is supplied to

 

the pump the air pushes the air piston down on a compression stroke

 

(forces as out of the gasoline conclude).

 

 Under the control of pilot pins (poppet valve) induced at each and every end of the stroke

 

two. GAS  Pushed Section

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 examine valve

 

opens to the highest permitting gasoline into the gas barrel and on the compression stroke

 

the inlet verify valve closes the discharge examine 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 greatest pressures of the pump ,however the

 

CZPT PTFE seals are appropriate 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 driven fuel boosters  that are not suitable for underground

coal mine programs .

CZPT Air driven gasoline boosters cycle routinely  as the outlet stress 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   

Design choice for fuel 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 up coming query is wheather you want the booster to stall when an outlet pressure is reached 

If so ,a easy airline stress regulator will suffice ,but bear in mind the movement drops off substantially 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  .

Air generate inlet	G1/two	Diameter of pressurizing chamber	63mm
Inlet port	NPT3/8 ”for Each and every port seperately	stroke	60mm
Outlet port	NPT3/8” for every single port seperately	Sound	<75dB
The two inlet port can be combined to one Inlet port with dimension of ZG3/8” The two outlet port can be comined with measurement of ZG3/8” ,the coming out thread dimensions CZPT foundation on  buyer”s requirements

 Remark 1) Maxium outlet strain are at an air driven pressure of eight bar or 116 PSI ,for lengthy lifestyle utilizing

of these kinds of pump ,we suggest that air driven stress should be not far more than 8 Bar  .
