Refer to Figure 1 which shows a part-sectional view of the 18B4B pump. The pump has: • A vertical top cone assembly (45) which incorporates the three diffusion pump stages (42, 6 and 5). • A horizontal side cone assembly (14). • A boiler (33), which forms part of the base of the pump. • A 'T' piece (38), which connects the top cone (45), the side cone (14) and the boiler (33). • A vertical backing condenser (17), which incorporates a baffle assembly (18). The diffusion pumping jet stages have top (5), second stage (6) and lower (42) vapour tubes, each of which has a jet cap (47, 44, 43)....

1.5.1 Cooling-fail thermal snap-switches Refer to Figure 1. The pump has two cooling-fail thermal snap-switches (7, 9) on the cooling-coils. These snap-switches protect the pump against damage due to failure of the cooling-water supply. Both snap-switches have normally closed contacts that will open if the temperature of the cooling coils increases above 46 °C. The snap-switches will reset automatically when the pump cools down. You must configure the snap-switches to switch off the electrical supply to the pump heaters when the snap-switch contacts open. You must also interlock the...
