Hot Sale Usun Model: 2GBT 15 60 Two Stage Air Driven Gas Pressure Test Pump for Safety Valve Test Bench

 CZPT Design :2GBT  160MM driven double stage ,double pushed air driven  gas

booster pump for cylinder testing  

 

CZPT air driven gas booster  pumps are ratio units that employ lower stress compressed

 

air driving a greater diameter piston (region x pressure) which is linearly connected to a smaller

 

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

 

CZPT Pump product numbers replicate the pumps nominal pressure ratio, while the complex data 

 

signifies specific ratios.  The outlet stall pressure is straightforward to set by adjusting the air push stress

 

by way of a simple air force regulator. By multiplying the force ratio by the accessible shop

 

air pressure, the nominal gas  stress can be calculated.
 

Instance ( Pump Model: 2GBT15/60 Gas booster pump)

Air drive piston region ( 160mm Ø)

CZPT plunger location ( 56/ 28mm Ø)

 one.  AIR Travel Part

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

 

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

 

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

 

(forces as out of the gasoline end).

 

 Under the control of pilot pins (poppet valve) activated at each finish of the stroke

 

2. GAS  Driven 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 out valve

 

opens to the optimum enabling gasoline into the gas barrel and on the compression stroke

 

the inlet check out valve closes the discharge check out 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 optimum pressures of the pump ,nonetheless the

 

CZPT PTFE seals are suitable for each the large 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 fuel boosters  that are not suitable for underground

coal mine purposes .

CZPT Air driven gas boosters cycle instantly  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   

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 next question is wheather you want the booster to stall when an outlet stress is reached 

If so ,a simple airline force regulator will suffice ,but don’t forget 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  .
