Abstract

A cryogenic adsorption pump comprises a suction element with a reservoir (4) for the cryo-agent of a lower temperature, a radiation screen embracing the suction element, a tube (25) and a thermal bridge (24). The radiation screen comprises a reservoir (15) for the cryo-agent of a higher temperature, an envelope (16) connected by its upper end to said reservoir (15) and by its lower end to the reservoir (4) of the suction element. The tube (25) passes through a gap between the internal walls of the reservoirs (4 and 15) and is connected by its lower end to the bottom (28) of a casing (1) and by its upper end to the reservoir (4) of the suction element. During the functioning of the pump a protective vacuum chamber (31) is created in the gap between the radiation screen and the casing, whereas a protective vacuum chamber (36) is created in the space situated between the radiation screen, the tube (25), the reservoir (4) of the suction element and the thermal bridge (24). These chambers (31 and 36) prevent heat exchange by the suction gases at pressures exceeding 10<-2>Pa, respectively, between the casing (1) and the radiation screen and between the first and the last suction elements.

20 Xia the waste of the agent in the vessel of the discharging element.

It is advisable that the treatment of the Russian Federation has an intercourse between the industrial and industrial sectors.

25 At this point, the pump and its preparation are simplified.

It is also advisable that the pump should be equipped with a large vessel, housed inside and inside the radiating vessel and discharging two pipes.

30 of κορπus.

After this, the vessel can be pre-loaded with a normal pump and the pump must be pumped out of the box. In other words, this optional 35 vessel plays a role of a nitrogen trap, all in all ^, for a radioactive agent.

There may be two emergency valves available for the plug, as long as they are connected to the input terminal, and this should be done from these valves. - 5 - Communicated with the atmosphere, and the second - with the danger between the vehicle and the radioactive equipment.

These valves increase the reliability of the pump, injured 5 by eliminating the hazardous heat from the destruction in emergency situations.

25 Between the housing and the radiating screen, a supplementary screen 23 has been installed, designed to reduce the thermal radiation of the external housing of the I radio frequency drive.

According to the invention, the pump contains a vacuum free warming area 24, made in the form of a quick access boiler

30 and installed between the reciprocating 16 radiant screen and the discharging element. The final end of the 24 hardware is connected to the upper part of the 16 for all of its use, and the lower end is free of charge. A small bridge 24 of 35 is made from a thick stainless steel tape with a thickness of 0.15-0.2 mm, so that its cross-sectional area was much smaller, and the hour was longer.

Then, the working chamber is disconnected from the pump and connected to it through the valve (not shown), one of the flanges, connected to one of them (40).

The 35th flange also through the valve connects to the mechanical pump and discharges the chamber through 38 pressure vessels, I Pa. With this vessel 38, the function of a nitrogen pond for steaming oils of a vacuum pump is not available. -10 - any falling into the pumped volume. This completes the process of initial vacuum operation of the working camera. Further, in the vessel 5, the outgoing element, one of which is 5 side 13, is filled with a coolant with a lower tempera- ture than the one in the vessel, the След In the last case, the decrease in the temperature of the refrigerant in the vessel 5, the discharging element is reached by pumping it through the pipe

10 and 13 are well suited. For the following, for example, 16 l / s over the course of two hours of working with the latter, in case 5, decreases to 55 а, and the following 50. As it is known, at temperature 63, liquid nitrogen is hardened.

15 Simultaneously with the vessel 5 through the devices 6, 7 and 8, the accessory, which is in the slots of the 10 wetting element, is cooled. It absorbs gases emitted from the working chamber, ensuring a minimum pressure of ~0 ^{~ 7} Pa and lower. With a temperature of about 50 Κ a special operation

25 After the aforementioned operations have been completed, we are ready to work and you can produce a high-quality working chamber that is connected to it. Removing unsuitable gases, such as helium and neon, produce magnetic discharges from the hose, 27.

30 In the event of an accident, for example, in the event of a rupture of atmospheres in the pump or by itself, if the liquid does not fill up at a pressure of 10 volts, the pressure is too high. In order to prevent the breakdown of the cooling unit 24 and the other components of the pump, in suitable cases after 35 tea, 44 (fig. 2) and 45 are increased. If the pressure increases, increase the pressure at 2.10 ⁴ Pa, the valve 45 starts (Fig. 2) and the pressure in these areas is equalized. Κлаπа - II - 44 starts up at pressure increase in the area of the pump above the atmosphere, also by -10 ^ Pa and connects the space of the pump with the atmosphere. 5 Τeshgovοy mοsτ 24 (φig.Ι) usτanοvlenny between οτκachi- vayuschim elemenτοm and οbechayκοy 16 ρadiatsiοnnοgο eκρana, and χοτya yavlyaeτsya isτοchniκοm neκοτοροgο τeπlοπρiτοκa κ οτκachivayu- present elemenτu on account svοey τeπlοtsροvοdnοsτi, οdnaκο daeτ vοzmοzhnοsτ οκρuzhiτ οτκachivayuschy elemenτ οχρannym vaκuumο

As a result, the calculation of the total pressure of the discharging element, for example, in the case of pumping, the pressure of 0.1 Pa decreases by 2.3.

The intentional use of the invention may be used to pump dust and plasma installations, for example, in electrical

30 on-site intentions, and also to receive a clear vacuum in the range of pressures of 10 to 10 Pa and in solving a wide range of tasks in the vacuum.
