19. Read the text “Pump Accessories”. Pay attention to the abbreviations, and Stone Wall Constructions. Summarize the text.
For small pumps the range of general accessories includes inlet and exhaust filters, traps and catch-pots to handle chemicals and liquids, oil treatment kits (экипировка), vibration isolators. Large oil-sealed pump accessories cover inlet and exhaust traps and filters, oil pressure monitoring and filtration devices, pump temperature controls and vibration isolators.
Mechanical booster and rotary pumps also feature high-efficiency inlet filters to trap dust and particulates, mineral and synthetic oil filters, liquid and chemical traps, and a wide selection of exhaust management systems.
Turbo-molecular STP type pumps can be fitted with an optional inlet vibration isolator. For vapor pumps, accessories include thermal snap-switches, baffles, traps and special isolation valves. For HT pumps we also offer a thermal probe to measure the pump temperature, a heat shield for the pump base and an inlet baffle to reduce backstreaming.
Accessories for leak detectors include gas spray, quartz and powder reference leaks, trolleys, communications connectors and extension leads.
20. Translate the following abbreviations and Stone Wall Constructions.
STP is an abbreviation from the standard temperature and pressure.
HT = high tension; STP = Standard Temperature and Pressure.

22. Study the prompts to the Vacuum/Pressure Pumps Selection and make their advertisement in small dialogues of your own.
Pump Types
Dry Pumps (non-lubricated) provide a clean vacuum over the entire vacuum range. Dry pumps require little maintenance and don't generate any waste material.
Water-Lubricated Pumps provide a rough vacuum at low initial cost and are very simple to operate. These pumps are corrosion resistant but are not suitable for water vapor sensitive systems.
Oil-Lubricated Pumps offer high capacities, high vacuum/pressure levels, and lower noise levels. Diffusion pumps feature an ultra-high vacuum. Oil-lubricated pumps, however, require routine maintenance and oil changes, and the oil may contaminate your vacuum.
To determine which pump is right for your application, calculate your free-air capacity by adding up the free-air requirements for all air-powered instruments. Add an additional 25% to allow for system variables and to provide capacity for future needs. Then determine the maximum vacuum or pressure required for your application – see the “Vacuum/Pressure Conversion Table” below for any necessary values.
