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.

A liquid flask with an adjustable layer thickness of the liquid under study is made in the form of an optical-mechanical attachment installed in the cuvette compartment of the FT-801 spectrometer. It contains focusing optics, removable holders of two windows-substrates with a diameter of 10 mm and two adjusting screws placed on the upper panel of the console housing and designed to set the required gap between the windows. A liquid of any degree of viscosity is pre-applied in the form of a small drop to the lower window and then, in the process of smooth convergence of the windows, evenly fills the gap between them. By rotating the adjusting screws and observing the transmission spectrum online, the user has the opportunity to set the desired thickness of the liquid layer, guided by the overall intensity of the entire spectrum or by the intensity of specific absorption bands. In the presence of calibration, which is easy to create using the ZaIR 3.5 program for several samples with a known concentration, the cuvette allows quantitative measurements. The flask is indispensable in the analysis of mixtures containing impurities in small proportions. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 50 The recommended number of scans when registering spectra is 16 Time of spectrum registration at 16 scans (resolution 4 cm-1), sec 20 Minimum volume of the studied liquid, mm3 1 The diameter of the focus spot, mm 3 Overall dimensions, mm 200×90×160 Weight, kg 1,1 The figure shows several spectra of the viscous lubricant "Buxol", illustrating the process of selecting the thickness of the sample layer between the windows. The measurement process has a high expressiveness and reproducibility, inexpensive replaceable substrate windows are used, the system is easy to configure and clean, a very small amount of sample is required to obtain high-quality spectra.

It is especially effective for use in products made of composite materials (including with honeycomb filler). Distinctive features: The AD-42 IP is a compact acoustic system sensitive to changes in mechanical impedance caused by product defects. The indication of the device indicates that there are voids, non-adhesives, delaminations or changes in the structure of composite materials (including with honeycomb filler and laminated plastics) under the sensor. The device is used to monitor various materials and their combinations. The energy consumption of the unit is low because the converter is switched on when the sensor is placed on the monitored product. Being light enough, the device allows you to perform monitoring in hard-to-reach places or in confined spaces. The results of the control can be stored in the built-in non-volatile memory and transferred to a PC. Converters Options: - 3 types of converters for various tasks Emitters: - 1 or 2 on each converter Switching-on: - The converters are switched on when they are placed on a controlled object. Technical characteristics: Weight, kg: 0.73 Dimensions, mm: 210x150x70 Power supply: 4 AA batteries Work without recharging the battery, h: 8 Battery discharge visual indication The defect alarm is visual on the converter and audible on the instrument panel (or) in headphones.

The 2NVBM-630(R)/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 2NVBM-630(R)/12000 booster pump is not less than 100 l/s. 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. Cooling water consumption 1200 l/h. The total amount of working fluid for the 2NVBM-630(R)/12000 pump is 65 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 1x10-2 to 1x10-1 mmHg). The operating mode of the pump in the range from 13.3 Pa (0.1 mmHg) to the maximum residual pressure is cyclically irregular.
