Equipment

The working surface of the stirrer is made of stainless steel and the platform is made of glass ceramics; can heat up to +500 °C. If this temperature is exceeded by 50 degrees, auto protection will work and the mixer will turn off. The speed range of the mixer is from 200 to 1500 rpm. The heated stirrer has an LCD screen that displays the set and actual temperature and rotation speed. Other animated icons show various operating parameters of the device. The creators of the stirrer paid great attention to the safety of the laboratory assistant: after turning off the stirrer, until the working surface cools down to +50 ° C, the inscription “PLATE HOT!” will flash on the screen. and current temperature value. At a given level, the stirrer can maintain either the temperature of the mixture or the temperature of the heating surface. To accurately maintain the mixture temperature there is an external PT1000 sensor.

The principle of operation of the electroplating thickness gauge: A converter with an induction coil on a ferrite core generates a high-frequency signal (frequency 1 MHz), which is used to create an alternating magnetic field. As the converter approaches the conductive surface, an alternating magnetic field creates eddy currents, the magnitude of which depends on the characteristics of the metal base and the thickness of the coating. In turn, eddy currents create their own electromagnetic field, which can be received by an induction coil. The resulting signal enters the amplitude detector, after which it is transmitted to the processing unit, where it is digitized and displayed on the device readout. In addition to signal conversion, the processor is used to set the required gain, as well as the initial voltage offset, depending on the characteristics of the materials in the controlled object. Features of the device design and advantages of the measurement method The TL-1MP eddy current thickness gauge consists of an electronic unit with a display, a power supply and a converter. The device is controlled using four buttons located on the front panel of the electronic unit. The converter can be disconnected from the electronic unit during transportation or for convenience of storage. The advantages of the device include: - convenience and ease of operation; - small size and light weight, allowing the TL-1MP to be used in difficult conditions with limited access to the controlled area of the facility; - high measurement accuracy; - factory setting of the measuring instrument to the customer's requirements; - high degree of localization of defects due to the small size of the converter. Scope of application: The service life of metal parts and components of mechanisms used in mechanical engineering is largely determined by their resistance to corrosion and surface wear. However, not all metals are sufficiently resistant to external destructive influences. Therefore, various electroplating coatings made of zinc, nickel, chromium, cadmium, tin, copper, silver and other metals are used to protect them. Even small fluctuations in the thickness of protective coatings can significantly affect the performance characteristics of parts, their service life, and interaction with other components. Therefore, measuring the thickness of the metal coating applied by the electrochemical method is important when conducting quality control of products. The use of the TL-1MP eddy current thickness gauge allows non-destructive quality control of electroplating coatings on the surface of metal parts in mass production conditions with special requirements for product quality. The device detects even small mechanical defects, the effects of abrasion, erosion, corrosion on the surface. Due to its ease of use, efficiency and reliability, eddy current thickness measurement is a standard method of quality control of products with electroplated coatings in such industries as mechanical engineering, aerospace industry.

The analyzer allows you to determine the content of sulfur and nitrogen in oil and petroleum products (diesel fuel, gasoline, kerosene, gas oil and any distillate petroleum products), hydrocarbon gas, liquefied petroleum gas (LPG), natural gas, liquefied natural gas (LNG), chemical synthesis products, biological materials by ultraviolet fluorescence and chemiluminescence. The analyzer is a proprietary development of NPO "SPEKTRON". The device is manufactured in St. Petersburg mainly from domestic components. There is a conclusion of the Ministry of Industry and Trade on the production of products in the territory of the Russian Federation. The analyzer is designed to determine: - mass fraction of sulfur in accordance with GOST ISO 20846-2016, GOST 34712-2021, GOST R 56866-2016, GOST 34237-2017, ASTM D5453-19, ASTM D6667-21, ASTM D7551-15, ISO 20729-17 ; - the mass fraction of nitrogen in accordance with ASTM D4629-17. A wide range of concentrations: from ultra-low to high. Modular principle: Each detector is a separate module. The device is equipped individually for each specific task. The possibility of simultaneous determination of sulfur and nitrogen in the analysis process. The principle of operation of the analyzer is to burn the test sample in an oxygen-enriched atmosphere or air at a temperature of 1050 ° C. The sulfur dioxide (SO2) and nitrogen oxide (NO) formed during combustion are transferred by carrier gas to the detection units with preliminary removal of water vapor, on the desiccant, and soot, on the filter. Determination of sulfur is carried out by ultraviolet fluorescence. Determination of nitrogen by chemiluminescence.

Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use

The working condition of the ND-1000 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. The working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-1000 diffusion pump is a maximum of 23 liters, a minimum of 16 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-1000 diffusion pump using two temperature sensors. The temperature sensor must be installed in a special radiator socket above the heater. In the event that there is a loss of working fluid and an increase in the temperature of the radiators to 360 0C for the ND-1000 diffusion pump, 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 1500 l/h, for the oil reflector 150 l / h and is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).
