Working Principle of Pressure Regulating Valve

Working Principle of Pressure Regulating Valve

Pressure Regulating Valve or commonly abbreviated to PRV is a component of hydraulic or pneumatic system that serves to adjust the fluid pressure of the high pressure system resources (such as pumps, compressors, or reservoir) to the low-pressure system. PRV is always in charge of maintaining fluid pressure value is lower than its supply pressure, therefore the pressure of the fluid before passing the PRV will always be greater than the pressure after passing through PRV. It can be said PRV serves to lower fluid pressure so that it meets system requirements specification, or also for the security and safety of use.

Broadly speaking there are two types of PRV when seen from operational systems, namely single stage and two-stage pressure regulator. The above picture illustrates a PRV system with only a single stage pressure regulator. The image appears on several major components such PRV inlet and outlet pressure gauge, diaphragm membrane, spring, poppet valve, as well as a lever to adjust the set point PRV working pressure. Pressure gauge serves as a good appointment fluid pressure value on the source side and the output side pressure of the PRV. Diaphragm function is to create a flexible working space in the PRV capable of changing volume. Two springs on the PRV system serves to generate pressure equilibrium, while Poppet valve serves to open and close the fluid flow.

The most fundamental difference of PRV with a two-stage pressure regulator as compared to the previous system is the two-stage system was used spring and diaphragm membrane that is more to create an equilibrium in the PRV chamber (chamber). At the time of the fluid pressure in the outlet room to fall, then spring 1 will suppress the diaphragm and poppet valve 1 so that a higher pressure fluid in the chamber will go into the outlet chamber. When the fluid pressure chamber drops because they have got into the room outlet, then the same process occurs in the spring 4 which will encourage the poppet valve 2 so that a higher pressure fluid went into the chamber. When the fluid pressure outlet is in conformity with the pressure set point was, the spring system will form an equilibrium so that both poppet valve will be fully closed.

Technology Development of Biological Pacemaker

Technology Development of Biological Pacemaker

The pacemaker is one of the emergency safety equipment. While this tool is very reliable for any emergency medical condition but this tool does have some limitations, including the failure of its parts and the risk of infection by viruses that come from the patient’sbody. Pacemakers must also undergo regular checking process and must be replaced periodically.Based on the background of this issue, a group of scientists trying to create a biological pacemaker that is expected to replace the electronic pacemaker role in the future.

One of the researchers, the biological pacemaker consists of electrically active cells that can be functionally integrated with the heart and give a naturalheart rate without requiring the presence of foreigners in the heart of the hardware.Theoretically, the approach to create a biological pacemaker is to transform stem cells into a special pacemaker commonly found in the sinoatrial node of the heart.Cells specialized pacemaker successfully created will then be transplanted into the patient’s heart to restore a normal heartbeat function. Another approach that can be used is by changing other cells in the heart, such as cells in the fibroblasts (connective tissue of the heart) and turn them into pacemaker cells.

So far the research is still tested on animals but has not really produced anything considered to be applied in human clinical therapy. Researchers still need to understand the mechanisms of control and maintenance of pacemaker cells that have been produced.In addition, the researchers found it necessary to develop a method of cell transplantation pacemaker in certain parts of the heart. Biological pacemaker should really be prepared in such a way with the higheststandards. Due to the failure of the pacemaker even for a moment can be very harmful to the patient’s life.

Know Your Ship Navigation System

Mengenal Sistem Navigasi Kapal Laut

Ship navigation system that is already set in the Global Maritime Distress adan Safety System (GMDSS). The GMDSS is an international agreement in which regulates communication procedures, the procedure’s safety, as well as the types of existing equipment on board vessels. The intent of the agreement is to improve safety and also to make procedures easy to implement in order to avoid danger. Existing communication systems in the GMDSS indeed have been specially designed to ensure the purpose of handling safety and distress signaling in the sea and this applies to the whole world. Of course, this system has other capabilities that send and receive signals transmitted by the danger that another ship, the ship affected so they can immediately get help as soon as possible. The system can also be used to study the safe route that will pass quickly and safely.

Some systems are incorporated in the GMDSS has long operated with functions as diverse as general radio communication which aims to ship communication tool through the existing radio networks on land and with regard to safety. Ship navigation systems such as alerting useful to give notice of the existence of a disaster or danger, and to coordinate an inter-ship aid.

Tool – navigation tools that are typically used in marine vessels such as radar (radio detection and ranging), GPS (global positioning system), RDF (radio direction finder), enchosounder, AIS (automatic identification system), and many others. The navigation tool must meet the standards set by the GMDSS as to ensure the safety of the crew is in the ships. Read more

The Impact of Precision Engineering on Society

Modern society is driven by advances in technology. Today, there are a whole host of devices and apparatuses that have been created thanks to advances in technology that make the life of the common man easier. Technology affects every walk of life, including things like manufacturing, astronomy, transportation, and food production.

When talking about advances in technology, a person would be remiss if they did not focus on the effect that precision engineering has had in making many of the technological marvels mankind takes for granted possible. Many people think of precision engineering as something that is relatively new. However, the truth is that precision engineers have worked to make mankind’s life better for thousands of years.



Precision engineering covers the creation of precision machine tools and the creation, research, development, and manufacturing of high accuracy components and their systems.

Precision engineering takes many different scientific and engineering skills and groups them together. Precision engineering only takes place in societies where a common technological solution can be used in multiple disciplines and on multiple products. An example of this can be seen when one looks at how ancient tool making worked with astronomy and horology to eventually create some of the modern tools that are used to map the stars as well as map the planet.

Precision engineering is seen in many different disciplines. Its purpose is always to come up with an innovative way to respond to the needs and wants of society.

Throughout history, there have always been two driving forces behind the advancement of precision engineering. Number one was military and defense. The second was trade. Intermixed between these two primary driving forces were secondary forces, which include fear, pride, inquisitiveness, and greed.

It is clear that even in modern society these forces are still driving precision engineering and precision engineers. The only difference is that in modern society, trade in the economy is a more powerful force than the military.

Currently, there are many different tools and procedures that are used in precision engineering. One technique that is widely used in precision engineering is CNC milling (computer numerical control milling). This process involves using a rotating cylindrical cutting tool. However, the CNC machine has the ability to move along multiple axis, and this allows it to create a wide array of complex shapes, holds, and slots.

Military and economic forces will continue to be the driving factor behind precision engineering. The result will be new technology that will have a positive impact on the way mankind lives.
