The AVDM-250 high-vacuum unit is a structure consisting of a vacuum diffusion oil-vapor pump, a nitrogen trap, a vacuum gate, a frame or a plate. The principle of operation of the AVDM-250 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-250 unit is operating, liquid nitrogen is poured into the trap. Condensation of working fluid vapors occurs on the elements of the freezing device cooled with liquid nitrogen. The frame (plate) is designed for mounting the components of the unit. The ends of the wires are connected to a connector mounted on the frame of the AVDM-250 unit.

The 2NVBM-500/12000 booster pump consists of housings, a steam pipe, a trap and a heater. The required effective speed of action of the pre-vacuum pump (pumps) at a pressure of 200 Pa (1.5 mm Hg) at the outlet of the booster pump is not less than 100 l/s. The maximum residual pressure of the 2NVBM-500/12000 pump measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6 × 10-4Pa (5 × 10-6 mm Hg). The pressure of the cooling water at the inlet to the pump 2NVBM-500/12000 should be from 0.2 to 0.5 MPa (from 2 to 5 kgf / cm2). The discharge from the pump should be free with a jet break. Cooling water consumption 1200 l/h. The total amount of working fluid for the 2NVBM-500/12000 pump is 65 liters, the level of working fluid should be between the upper and lower marks of the level gauge. Replacement or refilling of the working fluid depends on the operating mode of the pump (inlet pressure, pumping duration, etc.) and the composition of the pumped medium, so the time after which the working fluid is replaced or refilled can be 100 hours or more. A large flow rate of the working fluid is observed when the pump is operating in the input pressure range from 1.33 to 13.3 Pa (from 1 · 10-2 to 1 · 10-1 mm Hg). The operating mode of the pump in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.

The 2NVBM-630(R)/12000 booster pump consists of housings, a steam pipe, a trap and a heater.

The maximum residual pressure of the pump measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6x10-4Pa (5x10-6mm Hg). The pressure of the cooling water at the pump inlet 2NVBM-630(P)/12000 should be from 0.2 to 0.5 MPa (from 2 to 5 kgf / cm2) The discharge from the pump should be free with a jet break.

The working fluid of the pump is water. These pumps are designed to work with liquids as well as gases and vapors slightly soluble in them that are not aggressive to the materials of the 2VVN1-3M pump design, not explosive and non-toxic. The use of a 2VVN1-3M(H) water-ring vacuum pump for pumping out water-gas mixtures is allowed only if the bulk of the water is separated and discharged at the pump entrance. Failure to comply with this requirement may lead to unacceptable overload of the electric motor and destruction of the working bodies of the 2VVN1-3M(H) pump. The vacuum water ring pump 2VVN1-3M (H) is manufactured in the climatic version of UHL (i.e. for moderate and cold climate) 4 and O4 according to the GOST standard 15150-69, meets the requirements of technical specifications TU 3648-015-00218526-2000, designed and manufactured taking into account the requirements of GOST R 52615-2006. Electricity grid must meet the requrimemnts of GOST 32144-2013

Mineral vacuum oil VACMA OIL 300 is made from high-quality base components with a composition of additives that improve operational properties, such as anti-wear, adhesive, anti-shock, anti-corrosion, demulsifying, anti-foam. The VACMA OIL 300 is used for vacuum booster steam oil pumps. The VACMA OIL 300 mineral vacuum oil is designed to work at a maximum of 80°C. If the temperature is increased to 90°C, the oil life will be reduced by half, if it is operated at very low temperatures, then water vapor can condense in the pump, thereby worsening the lubricating properties of the oil.
