Guidelines to Designing Your Own Chambers
When you require a quotation for a chamber of your own design, use the following guidelines to specify your requirements. This will help you in the quickest and most accurate way possible.
- First identify your basic chamber style.
Style 1 = Spherical chamber
Style 2 = Cylindrical with flanged 'open' ends, i.e preparation chamber.
Style 3 = Open flanged end and dished closed end, i.e analysis chamber. - After you have identified chamber style, complete a port table. Number each port and state the flange and tube size required.
- Focal points- indicate each focal point with a letter. Reference each port (where applicable) to this letter on the port table. Indicate any focal point heights that you have, this is the distance from the base flange to the focal point. The base flange should always be port 1. Fore spherical and preparation chambers indicate the main flange as port 1.
- Port length - this is the distance from the front flange face to the focal point. Indicate this length on your port table.
- Port length tolerance - state this even if it is the standard tolerances, remember that overly high tolerances may increase the amount of work involved and the price of your chamber.
- Beta and Gamma angles - these are indicated in a clockwise direction. If special tolerances are required, add these to the table.
- Bolt hole position - bolt holes are normally positioned relative to the flange axis. There are 2 normal versions, straddled (bolt holes straddle the defined port axis) and in-line (bolt hole on defined port axis).
- Accessories it is advisable to inform us what accessory is going to be mounted onto each port. It can be used as an added check that port diameters are correct. However please note that the ultimate responsibility must rest with you the customer.
