TRANG CHỦ Sản phẩm Parr Oxygen Bomb Calorimeters 6400 Thiết bị đo nhiệt trị tự động


Đặc điểm thiết kế 


  • Kỹ thuật gắn cố định Bom và Bình chứa nước

Với thiết kế Bom và bình chứa được gắn cố định không cần tháo ra khỏi thiết bị trong quá trinh vận hành, cho phép duy trì một hệ thống làm việc tự động hoàn toàn.


  • Oxygen Charging and Release

The fixed bomb and bucket design allow the oxygen supply to be directed into the head of the bomb at the beginning of each test. The head of these bombs incorporate a check valve which dynamically seals when the bomb is pressurized. At the end of the test, the gases in the bomb are automatically released while the calorimeter is being returned to its starting temperature.


  • Fixed Bucket

The bucket in these calorimeters has been designed to provide smooth circulation over the surface of the vessel. The design also repeatedly fills the bucket volumetrically. The bomb head closure seals the bucket at the same time the bomb is closed. This unique design minimizes the amount of water required for the test as well as permitting rapid, automatic and repeatable filling for each test. The water heated by the combustion is automatically drained from the bucket at the conclusion of the test and replaced with cooling water to bring the bomb and bucket rapidly back down to the starting temperature for the next test.


  • Fixed Bomb

The 6400 Calorimeter features the patented closure design of the Parr Fixed bombs. This design allows the user to seal and lock the head into the cylinder with simple one sixteenth turn. The main bomb seal is an o-ring optimized to minimize frictional wear, improving the lifetime of this seal. At the conclusion of the test the inside surface of the bomb is washed to remove the products of the combustion from the bomb. The automation of the bomb washing step eliminates one of the most tedious and time consuming manual operations required with removable bomb calorimeters. Besides the elimination of the drudgery of manually washing the bomb, a not so obvious advantage of the fixed bomb design is that the bomb is always washed as soon as the final temperature can be determined. Generally, this is within 4-5 minutes of the time the bomb is fired. This holds to an absolute minimum the time any acids produced by the combustion can attach to the inner surfaces of the bomb. This has improved the service life of these bombs in comparison to removable bombs.


1138 Oxygen Combustion Bomb

The 1138 oxygen bomb is the standard bomb in the 6400 calorimeter. The 1138 Oxygen Bomb has been redesigned to withstand a higher magnitude of tests. The head is designed with an O-ring groove which is optimized to minimize frictional wear, in turn improving the lifetime of the seal. The bomb head is removable for fast sample loading using the patented Quick Twist-Lock vessel closure design.

The bomb is made from alloy 20; a special niobium stabilized stainless steel selected for its resistance to the mixed nitric and sulfuric acids produced during the combustion process. The 1138CL is made from the halogen resistant Hastelloy G30™. Hastelloy 30™ is an alloy rich in cobalt and molybdenum and is able to resist the corrosive effects of free chlorine and halogen acids produced when burning samples with significant chlorine content. While no alloy will completely resist the corrosive atmospheres produced when burning samples containing halogen compounds, users who intend to test these materials are urged to select the 1138CL Bomb.

These bombs are 250 mL in volume and are rated to a working pressure of 2000 psi. The bombs are hydrostatically tested to 3000 psi and the sample range is ~1g releasing up to 8000 calories per test.


A1450DD Head

Users who wish to achieve maximum through-put with their 6400 calorimeters will want to purchase a spare A1450DD head for their calorimeter. This permits the next sample to be completely prepared and inserted into the bomb as soon as the current test is concluded.


Control Charts      

A control chart is a graphical tool which can assist the user in determining whether or not their process is in control. Many standard methods will dictate that a reference sample be measured periodically and the results plotted on a graph. Limits for acceptable values are defined and the process is assumed to be in control as long as the results stay within these limits. Since results are expected to scatter with a normal distribution within established limits, systematic trends or patterns in the data plots may also be an early warning of problems. The 6400 calorimeter provides the user with the ability to instantaneously plot and view standard results with user defined warning and control limits.
