The device allows you to detect surface defects like cracks, visualizing the signal from the continuity interruptions on the display. The design of the flaw detector allows to determine with high reliability the exact location and depth of defects even on rough surfaces of flat and curved shape, including under a layer of corrosion or in the presence of a protective coating of the controlled area of the product with a thickness of up to 3 mm. The principle of operation of the VD-12NFP eddy current flaw detector: The principle of operation of the VD-12NFP eddy current flaw detector is based on the phenomenon of electromagnetic induction. An alternating magnetic field created in the primary coil of the converter by means of a sinusoidal voltage generator excites eddy currents in the controlled product. A parasitic magnetic field formed by eddy currents at the locations of defects affects the measuring unit (two signal coils connected in series) of the converter, creating an electromotive force in it. The amplitude and phase of the secondary signal carries information about the properties of the defect and the position of the transducer relative to the surface of the controlled product. The output signal from the measuring unit of the converter, after amplification and processing using a microprocessor, is displayed on the readout of the device, and is also stored in the memory block for subsequent transmission to a personal computer. In addition, information about the defects is displayed on a piezoelectric bell used as an audio indicator. Design, features and advantages of the VD-12NFP eddy current control device: The VD-12NFP eddy current flaw detector is a portable device capable of working both in a desktop and in a suspended position in a special bag-case. This ensures convenient operation of the device in a variety of conditions: in the laboratory, in the factory shop or during field tests. The flaw detector consists of an electronic unit with controls and display of test results, as well as three replaceable converters with wear-resistant corundum tips connected to the electronic unit using a connector. The choice of the desired converter depends on the magnetic properties of the material. For the control of parts with grooves, a converter with an inclined tip is offered. The device is powered by 4 AA batteries located in the battery compartment of the electronic unit. The advantages of the flaw detector include: - a screen for visualizing the signal during measurement; - light weight and compact dimensions that allow you to use the device in almost any conditions; - the ability to control the quality of products of various curvature and surface roughness even in the presence of a protective coating or a layer of corrosion; - wear resistance of converters, which is important when monitoring products with increased surface roughness (up to Rz£320); - automatic detection of the type of converter when connected, as well as the presence of built-in memory for storing control results; - the possibility to transfer data to a personal computer for storing or printing control protocols. Scope of application: Portability, high productivity, the ability to work with curved and rough surfaces, as well as the fact that the operation of the flaw detector is practically unaffected by humidity, pressure and contamination of the gas environment or the surface of the controlled product with non-conductive substances ensure the versatility of the device for detecting cracks in various materials. The eddy current flaw detector VD-12NFP is actively used in heavy industry for diagnostics of metal structures, assemblies and mechanisms for various purposes in factory workshops or laboratories, including at enterprises of railway transport, automotive industry, mechanical engineering, pipelines and metal structures. The VD-12NFP flaw detector can be used with equal success in the field, factory workshops, depots, laboratories and workshops to monitor the current condition, as well as to assess the degree of wear, the possibility and duration of further operation of such products made of metals and alloys as over-spring beams, wagon wheels, auto coupler housings, side frames, wheel couples and others.

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.
