The principle of operation of the device The principle of operation of the irradiator is based on the conversion of DC electrical energy into a normalized flow of ultraviolet radiation in the optical wavelength range of 350 ... 400 nm with a maximum at a wavelength of 365 nm. Design features and advantages The irradiator is a lantern consisting of an ultraviolet diode placed behind the focusing system, connected to a DC voltage converter, which supports the optimal mode of starting and functioning of the LED. Structurally, the irradiator is made in a lightweight duralumin housing, in the front of which there is a focusing system with an ultraviolet LED. The housing is equipped with a carrying strap. There is also a power on/off button on the case. As the power source of the irradiator, a lithium-ion battery of type 18650 with a nominal voltage of 3.7 V or 3 AA batteries with a voltage of 1.5V. are used. An ultraviolet LED is used as a source of ultraviolet (UV) radiation. The use of an LED distinguishes the UFO-3-20F irradiator from similar devices using UV lamps, it provides: high reliability and durability; variable diameter of the UV radiation zone; low current consumption and long continuous operation time; instant readiness for the first and subsequent turn-on; low weight, compact; high radiation intensity; stability of the characteristics of the irradiator, both during operation and throughout its entire life; wide operating temperature range.

The operation of the NVDM-250 diffusion pump is based on the capture and transfer of the pumped gas by a steam jet flowing from the slit gaps of the steam line nozzles towards the outlet flange. The oil reflector of the NVDM-250 diffusion pump is a flange with a cooling tube passing through it, soldered to a cap located in the center of the flange. The NVDM-250 open-type diffusion pump heater is a metal housing with a ceramic base laid in it with a heating element in the form of a spiral made of nichrome wire. During the operation of the pump, it is necessary to monitor the flow rate and temperature of the cooling water, the level of the working fluid and its temperature. 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. Therefore, the time after which the working fluid is replaced or refilled can be from 100 to 1000 or more hours. A large flow rate of the working fluid is observed when the pump is operating in the range of inlet pressures from 6.6 × 10-2 to 13.3 Pa (from 5 ×10-4 to 1 ×10-1 mmHg). Water at the inlet to the cooling systems of the housing and oil reflector must be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 4°C to plus 25°C. The recommended cooling water consumption is 100+15 l/h and is regulated by the outlet water temperature, which should not exceed plus 400C. The water drain should be free (with a jet break). Not allowed: operation of the pump without water cooling, exceeding the maximum exhaust pressure of 33.3 Pa (0.25 mmHg) The level of the working fluid during operation, at which the parameters of the pump NVDM-250 are provided, must correspond to min 8mm, max 13mm. The volume of the filled working fluid is 0.55 l
