Educational film, tells about different ways of obtaining vacuum, about types of vacuum pumps, and also about devices with which vacuum is measured
A factory workshop, female employees in white coats working with equipment.
Close-up - a bottle being burned on a special burner.
An employee works with special equipment - a pump, which creates a vacuum.
Close-up - pump parts.
Plates with types of vacuum pumps appear on the screen - mechanical, jet, sorption.
In the frame - a vacuum pump.
Close-up - a hand pressing a button on the control panel.
In the frame - the process of preliminary discharge by a forevacuum pump.
The diagram shows the structure of various mechanical vacuum pumps.
The structure and operating principle of a vane-rotor pump are shown.
The structure and operating principle of a vane-stator rotary pump are shown.
The structure and operating principle of a two-rotor Roots pump are shown.
The structure and operating principle of a molecular pump are shown.
The structure and operating principle of a turbomolecular pump are shown.
Close-up - a hand holds a simple jet pump (water-jet).
The operating principle of a water-jet pump is shown.
Close-up - an ejector steam-jet pump system is on the table in the laboratory, the operating principle of such a pump is shown (in this case, the working fluid is not water jets, but mercury or oil vapor).
Close-up - a hand switches a toggle switch on the equipment.
Close-up - a device scale with a moving arrow.
In the frame - a diffusion pump.
The structure and operating principle of a diffusion pump are shown.
The figure shows one of the types of diffusion pump - a multistage pump.
The figure shows special screens that all steam-jet pumps are equipped with.
The purpose of the screens is to prevent mercury or oil vapor from entering the pumped volume.
The figure shows screens with water or nitrogen cooling.
One of the types of sorption pumps is a getter pump.
The structure and operating principle of a getter pump are shown.
The structure and operating principle of a magnetic discharge pump are shown.
Close-up - on the table are flasks and laboratory glassware with a special substance - zeolite.
The figure shows that 1 gram of zeolite has a surface area of about 1000 m2. It shows how gas is bound on this surface.
It shows the structure and operating principle of a zeolite pump.
The frame shows the operation of a zeolite pump in a workshop (at low temperatures).
Panorama of the pump.
The man disconnects the pump from the volume being pumped out (since the zeolite has become saturated).
The figure shows how the zeolite is ready for operation again after heating.
Close-up - a hose is connected to the pump.
Close-up - a flask on a table, it shows how gas is frozen on a cooled surface.
It shows how this principle is used in cryogenic pumps.
It shows the structure and operating principle of a cryogenic pump.
The frame shows a cryogenic pump.
Vacuum measurements.
Close-up - an ejector steam-jet pump system is on the table in the laboratory, the process of obtaining a vacuum takes place.
The simplest absolute pressure gauge here is a U-shaped pressure gauge.
To measure low pressures, a McLeod compression manometer is used.
The operating principle of such a manometer is shown.
Close-up - a hand moves the manometer scale.
The frame shows a thermocouple and ionization vacuum gauges (indirect methods of measuring pressure).
The structure and operating principle of a thermocouple vacuum gauge is shown.
The frame shows an ionization vacuum gauge.
Close-up - a hand switches a toggle switch, an arrow moves on the scale of the device.
The structure and operating principle of an ionization vacuum gauge is shown.
The structure and operating principle of a magnetic-discharge vacuum gauge is shown.
The frame shows various devices (manometers, vacuum gauges, etc.).
Panorama of the mass spectrometer device.
The figure shows the structure and operating principle of such a measuring device.
Panorama of the mass spectrometer.
It shows what a fragment of the spectrum of residual gases looks like (a curve is printed on paper, a hand writes numbers on the peaks of the curve).
Close-up - the PTI-10 Helium Leak Detector device.
The device in the general plan.
Shown is how the pumped-out volume is blown with helium.
If the device detects helium in the pumped-out volume, this will be a signal of a leak in this place.
In the frame is modern vacuum equipment, an employee works with the equipment, the data of the devices is printed on an automatic typewriter.
Large - numbers on the device (digital voltmeter B7-23).
