Mechanism of Cryopump. This pump features a clean vacuum and high pumping speed. A cryopump is an accumulating type vacuum pump. The pump condenses and adsorbs gases on a cryogenic surface installed in the pump to create a condition from high vacuum to ultra-high vacuum.Also, this pump can obtain a clean vacuum that is not contaminated by oil and has a …

The cryopump operates on the principle that gases can be condensed and held at extremely low vapor pressures, achieving high speeds and throughputs, as described in Table 1-1 - Table 1-11.

Aerospace customer noticed that a cryopump installed on a large vacuum chamber would not pump down below 10 -5 range. Additionally he found oil contaminants on the 80K array. While there is oil used in the cryogenic system in the compressor and it can contaminate the helium circuit, this oil can not physically reach the vacuum vessel.

Cryocondensation is the physical and reversible bonding of gas molecules through Van der Waals forces on sufficiently cold surfaces of the same material. The bond energy is equal to the energy of vaporization of the solid gas bonded to the surface and thus decreases as the thickness of the condensate increases as does the vapor pressure.

1.Cautions about pressure. A cryopump can store large amount of condensable gases inside. However, it is dangerous to warm up a sealed cryopump as the inner pressure may reach several MPaG. To prevent an explosion, CRYO-U cryopump is provided with a pressure relief valve which starts opening at 10kPa (gage) and fully opens at 20kPa (gage).

least partly covered with a porous sorbent material. The design of a cryopump has to combine cryogenic aspects and technological vacuum consider ations in a unique manner, as the generation of low temperature itself presupposes the existence of vacuum conditions and vice versa. Thus, the cryopump is by its physical principle a high-vacuum pump.

The cryopump operates on the principle that gases can be condensed and held at extremely low vapor pressures, achieving high speeds and through puts. This Cryo-Torr 8F Pump is a highly-reliable and rugged unit that requires a minimum of servicing. Since the cryopump exposes no moving parts, operating fluids, or backing pumps to the vacuum, the ...

The cryopump was connected to the test system and successfully passed several regenerations. We concluded that the cryopump probably had a small vacuum leak at the vacuum vessel flange. It was indicated that this is plausible since they do not change the flange O-Ring each time they replace the cryopump.

The capacity C of a cryopump is how much gas can the pump condense before it reduces its performance. The value C in bar*l is, for example, for a 10,000 l/s pump; 5,500 bar*l for air. With this we can calculate the regeneration time t depending on gas flow according to: At pressures of 10-5 mbar, we come to a time of 636 days – or almost 2 years. At lower …

Start the cryopump operation as follows. （1）Turn ON the main power. （2）Circulate cooling water for water-cooling type compressor unit. （3）Rough pump inside the cryopump to 40Pa.（Do not rough pump to 13 to 20Pa or below because it may cause oil contamination by oil backflow of rotary pump.

The amount of gas that a cryopump can retain is referred to as its ca-pacity for a given species of gas. This capacity is the total volume of gas that can be pumped before the cryopump has to be warmed up and the gas vented (a process known as regeneration).

1. Installation of Cryopumps. CRYO-U Cryopumps can be attached in any position since a small-type helium refrigerator is used, except for CRYO-U30 and U22. However, it is preferable to use a cryopump in the same direction to prevent seal abrasion. For Hydrogen Vapor Pressure Gauge, position cryopumps at the proper location to monitor the ...
