Merchandise Description
USUN Design :GB02 160MM pushed pneumatic driven natural Fuel Booster Pump
for Charging Cylinders
Usun air driven gasoline booster pumps are ratio devices that use low stress compressed
air driving a greater diameter piston (location x force) which is linearly connected to a more compact
hydraulic piston/plunger. Using this ratio principal, a larger hydraulic force can be created.
Usun Pump product numbers reflect the pumps nominal force ratio, even though the complex data
signifies exact ratios. The outlet stall pressure is straightforward to set by modifying the air push strain
through a simple air stress regulator. By multiplying the pressure ratio by the obtainable shop
air pressure, the nominal gas stress can be calculated.
Instance ( Pump Product: GB25 Gasoline booster pump)
Air travel piston area ( 160mm Ø)
Hydraulic plunger location (32mm Ø)
True ratio = 25:1
one. AIR Travel Section
The air generate segment is made up of a light fat piston total with seals managing within 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 end).
Under the control of pilot pins (poppet valve) induced at every single end of the stroke
2. GAS Driven Segment
The gas section of a USUN 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 highest allowing fuel into the gasoline barrel and on the compression stroke
the inlet verify valve closes the discharge verify valve opens forcing the pumped fuel
into the procedure .The main high pressure seals is located on the gas piston and they seal agaist
the gas barrel during operation . and the highest pressures of the pump ,even so the
normal PTFE seals are appropriate for both the large greater part of gases encountered .
Other materials of construction can be supplied to meet more aggresive services
.The standard serials of booster are not suitable for underground coal mine applications .
USUN DO Manufacture models of air driven gas boosters that are not suitable for underground
coal mine applications .
USUN Air pushed gasoline boosters cycle immediately 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 .
USUN 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
USUN for flow conditions not shown in charts
Product selection 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 next query is wheather you want the booster to stall when an outlet pressure is reached
If so ,a straightforward airline pressure regulator will suffice ,but bear in mind the stream 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 .

two. No heat,flame or spark danger
3. Infinitely variable biking velocity and output
4. Air pushed Versions do not call for electrical link ,effortless to use automatic controls
five. No limit or adverse impact to contineous end/commence programs
6.Seals technique developed for long operating lifestyle,No airline lubricated required
seven.Built-in coupling method (Most models) and suited for most gases boosting

How to check the vacuum pump
A vacuum pump is a machine that draws gas molecules from a volume and maintains a partial vacuum. Its main job is to create a relative vacuum within the stated capabilities. If your vacuum pump isn’t working properly, it may need service. Read on to learn more about the types of vacuum pumps and how to check them. 
Principle of industrial vacuum pump
Industrial vacuum pumps are used in industrial processes that require vacuum. These pumps are designed to generate, improve and maintain vacuum. Learn about the different types of industrial vacuum technology. You can start by reading about the most common types of industrial vacuum pumps. These pumps can be used in a variety of industrial processes from cleaning to manufacturing.
Regardless of the technology used to manufacture these pumps, the basic principles behind their operation are the same. The speed and mass flow of the pump will determine its capacity and suitability. A faster flow rate will minimize the time it takes for the machine to empty. Another important factor to consider is the type of vacuum you need.
A liquid ring vacuum pump is an industrial pump that uses a ring of liquid to form a seal. This type of pump is best suited for applications with high vapor loads and high liquid carry-over. Liquid ring vacuum pumps can be divided into two categories: liquid ring vacuum pumps and scroll vacuum pumps.
Industrial vacuum pumps work by removing gas molecules from a chamber. The partial vacuum created allows material to flow through the void. As more molecules are removed, the pressure in the chamber decreases, releasing energy that can be used for a variety of different purposes.
The most common use of industrial vacuum pumps is for electric lights. In these lamps, a vacuum pump removes the gas, causing the bulb to light up. Energy from the vacuum is also used in aircraft to power instruments. In addition to powering industrial vacuum cleaners, they are used in a variety of other environments.
High-performance industrial vacuum systems require specific materials that can withstand extreme pressure. This means that the materials used in these systems need to be properly checked. They must also be free of organic debris and other contaminants before they can be safely placed in the chamber.
Types of vacuum pumps
There are various types of vacuum pumps. Which one to choose should depend on the purpose of the pump and the degree of vacuum that must be achieved. It is mainly divided into three categories: rough vacuum or low vacuum, high vacuum and ultra-high vacuum. They all have varying degrees of scarcity. The higher the pressure, the fewer molecules per cubic centimeter. This in turn improves vacuum quality.
The vacuum pump is critical to the operation of the vacuum system. These devices are divided into three main categories according to their working pressure range. These pumps have different characteristics and technologies that make them ideal for specific applications. The choice of vacuum pump required for a particular application depends on how much vacuum you need, and how much power you are willing to spend.
Vacuum pumps are used in a variety of industrial and scientific processes. Their main function is to remove gas molecules from the sealed volume, leaving a partial vacuum. There are many different types of vacuum pumps, including rotary piston, liquid ring and scroll vacuum pumps. In addition, turbomolecular pumps are used.
Dry vacuum pumps are more expensive than wet vacuum pumps. Wet vacuum pumps use oil as their lubricating fluid. Different types of oils are used depending on the application. Some wet pumps have additional features, including contaminant filtration. However, wet systems have one major disadvantage: the contact between oil and fluid. To avoid this, oil separators are usually used.
There are several different types of vacuum pumps. The basic type is the positive displacement pump. It operates by expanding the chamber and removing gas molecules. The intake valve draws fluid into the chamber, while the exhaust valve opens when the chamber is at maximum expansion. This cycle repeats several times per second. Positive displacement pumps are often used in multistage vacuum systems. 
Maintenance of vacuum pump
Regular maintenance is very important to ensure the long-term effective use of the vacuum pump. One way to ensure proper pump performance is to change the oil regularly. Pump oil may be contaminated by vapor condensation. To avoid this problem, close the inlet valve for 20 to 30 minutes before applying vacuum. It is also important to install an inlet cold trap to protect the pump from corrosive vapors.
Another way to prolong the life of your vacuum pump is to periodically remove any solvent in it. This step reduces internal corrosion and prevents premature pump failure. During maintenance, be sure to disconnect the power supply to the vacuum pump. After cleaning, store it in a dry and safe place. The pump should also be disposed of in accordance with local regulations.
Vacuum pumps may require frequent oil changes, especially when used in wet chemistry. The standard rule is to change the oil after 3,000 hours of use, but some pumps require more frequent oil changes. It is also important to clean the oil regularly, as dirty or discolored oil can affect the performance of the pump.
Vacuum pumps are often equipped with on-site glass to allow the user to visually check the oil level. Clean oil will appear transparent, while dirty oil will appear darker. Frequent oil changes are essential, as oil changes can help spot various potential problems. Changes in vacuum pump performance or strange noises are also good indicators of a problem.
After an oil change, the vacuum pump should be cleaned thoroughly with a soft cloth and mild degreaser. Oil changes should take less than ten minutes, and they will extend the life of your equipment. Additionally, the outside of the pump should be wiped with a cloth or rag.
The pump must be properly vented to avoid internal corrosion. If possible, place the pump away from hot equipment or rooms. Overheating can reduce the viscosity of the oil and cause premature pump failure. In addition, it can lead to overwork of other expensive scientific equipment. Heat can also cause cracked rubber parts and oil leaks. 
Signs of damage to the vacuum pump
A bad vacuum pump can cause a variety of automotive problems, including poor fuel economy, difficult braking, undercarriage oil leaks, and faulty air conditioning. If any of these problems occur, call a mechanic to check your vehicle’s vacuum pump. You can also check the air conditioner and brake pedal to see if they are working properly.
A loud noise from the pump can also be a symptom of a malfunction. These noises are often caused by the aging and accumulated wear of specific components. If this is the case, the diaphragm, valve plate or seals may need to be replaced. However, if the noise is coming from bearings or other areas, more extensive repairs may be required. Additionally, dust and other contaminants can enter the pump chamber, which can degrade pump performance.
If the vacuum pump won’t start, it could be a blown fuse or a power or voltage problem. Other common causes are flow restrictions or improper installation at the entrance. Also, the vacuum pump may be damaged or the capacitors may be of poor quality. It’s not always easy to tell if a vacuum pump is leaking oil, but a greasy transmission can indicate a vacuum pump failure.
A leaking vacuum pump can also hiss when the car’s engine is running. If you hear it, check the hoses and connections to make sure there are no leaks. A vacuum leak may indicate a faulty vacuum pump, so you need to replace it as soon as possible.
Checking end pressure is easy, but a pressure gauge can also serve as a sign. You can also check for pump vibration by running a short procedure. Excessive vibration can be subtle, but it can greatly affect your process. If you notice excessive pump vibration, you should contact a professional immediately.
Poor pump performance can cause many problems for your company. A bad vacuum pump not only wastes material, it also damages your tools and reputation.
