CZPT  CZPT Design :2GB130  160MM driven  single motion,double head air

driven high strain air pushed gasoline booster pump  

 

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

 

air driving a more substantial diameter piston (location x pressure) which is linearly linked to a smaller

 

hydraulic piston/plunger. Making use of this ratio principal, a greater hydraulic force can be created.

 

CZPT Pump design figures reflect the pumps nominal pressure ratio, although the complex data 

 

signifies actual ratios.  The outlet stall strain is easy to set by modifying the air push force

 

through a simple air pressure regulator. By multiplying the pressure ratio by the offered store

 

air pressure, the nominal gas  pressure can be calculated.

Actual ratio = 25:one

 

 1.  AIR Push Part

 

The air travel section consists of a gentle fat piston total with seals working 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) induced at every stop of the stroke

 

2. GAS  Pushed Part

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 valve

 

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

 

the inlet check valve closes the discharge verify valve opens forcing the pumped fuel

 

 into the approach  .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 appropriate for equally 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 gasoline boosters  that are not suitable for underground

coal mine apps .

CZPT Air driven fuel boosters cycle immediately  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   

Product assortment 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 concern is wheather you want the booster to stall when an outlet pressure is reached 

If so ,a easy airline pressure regulator will suffice ,but bear in mind the stream 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  .

 Remark one) Maxium outlet stress are at an air pushed stress of 8 bar or 116 PSI ,for long life utilizing

of this kind of pump ,we suggest that air pushed pressure ought to be not much more than 8 Bar  .
