The use of a 2VVN1-25(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 parts of the 2VVN1-25(H) pump. The 2VVN1-25(H) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) according to 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. The quality of electricity must meet the requrimemnts of GOST 32144-2013.

The 2NVBM-250(R)/3000 booster pump consists of housings, a steam pipe, a trap and a heater. The alignment of the steam line in the pump housing 2NVBM-250(R)/3000 is carried out by a steam line screed, which, when installing the housing on the collector, enters its upper end into the hole of the hood (oil reflector). The required effective speed of action of the forevacuum pump (pumps) at a pressure of 200 Pa (1.5 mm Hg) at the outlet of the 2NVBM-250(R)/3000 booster pump is not less than 25 l/s. The maximum residual pressure of the 2NVBM-250(R)/3000 pump measured by the PMI-2 manometric ionization converter with nitrogen filled into its trap, is no more than 6.6 × 10-4 Pa (5 × 10-6 mm Hg). The pressure of the cooling water at the inlet to the 2NVBM-250(R)/3000 pump should be from 0.2 to 0.5 MPa (from 2 to 5 kgf / cm2). The drain from the pump must be free with a jet break. Cooling water consumption is 360 l/h. The total amount of working fluid for the 2NVBM-250(R)/3000 pump is 17 liters, the level of the 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 complex includes: single-flow turbomolecular vacuum pump VGTN-150; frequency converter; set of mounting parts; operation manual. For connecting to the pre-vacuum pumping system, the pump is equipped with an ISO-KF25 exhaust flange. If necessary, it can be upgraded with an ISO-KF16 flange for purging the pump with inert gas. Pump cooling is combined. Based on the operating conditions, the complex can work both with forced air cooling and with water cooling. The working orientation in space is arbitrary. One of the key features of the pump is that a breakthrough of the atmosphere is possible. This has become possible due to the production of a turbine from a solid billet and a special, rigid design of the bearing assembly.

The working fluid of the pump is water. The use of the 3VVN1-12M(H) 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 engine and destruction of the pump's working parts. The 3VVN1-12M(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-12M(H) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) according to GOST standard 15150-69, meets the requirements of technical specifications TU 3648-053-00218526-2013, designed and manufactured taking into account the requirements of GOST R 52615-2006.

The NVD-600 two-rotor vacuum pump is not designed for pumping air, vapors and vapor-gas mixtures from one volume to another. The NVD-600 two-rotor pump can only work in conjunction with a pre-vacuum pump, and is designed for pumping in the pressure range from 1.3·102Pa (1 mm Hg) to the maximum residual pressure. The speed of action of the forvacuum pump for NVD-600 is not less than 60 m3/h. The temperature of the pumped media at the inlet to the pump NVD-600 should not exceed the maximum operating values of the ambient temperature according to GOST standard 15150-69, at which the pump is operated. At an operating pressure of more than 5 mm Hg for the HVD-600, the bypass valve is in the open position. The pumped gas is partially bypassed through channels in the pump housing from the outlet to the inlet of the pump NVD-600, which ensures the operability of the pre-vacuum pump and prevents overheating of the pump NVD-600. The NVD-600 double-rotor vacuum pump can operate continuously at an inlet pressure of no more than 133 Pa (1 mm Hg) or pumping out one or more sealed vessels with a total volume of 7.5 m3 for the pump from atmospheric to the maximum residual pressure for 8 hours.

The vacuum membrane pump PL.HM02.01.4 is a universal device made in Russia from the Primelab company. Made from high-quality materials, including fluoroplastic, used to create sealed chambers, and a protective coating for safe operation of the device. The technical characteristics of the pump depend on the method of connecting the chambers. With a series connection, the performance will be 38 l/min at a maximum vacuum of 4 mbar. Parallel and independent connections will allow you to achieve completely different performance indicators of the device. The vacuum diaphragm pump PL.HM02.01.4 Primelab is convenient to use. It has a light weight of 9 kg, compact dimensions (321.5x160x200 mm) and creates a minimum of noise (up to 75 dB).

The working condition of the ND-630 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (uner technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-630 diffusion pump is a maximum of 9 liters, a minimum of 6 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-630 diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-630 diffusion pump up to 360°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 600 l/h, for the oil reflector it is 80 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).
