Description of the vacuum plate-roting pump 2NVR-5DG Vacuum NACOC 2NVR-5DG is designed to pump from sealed volumes and pumping into sealed volumes to absolute exhaust pressure, as well as inert (for example: helium, argon, etc.) and toxic gases that are non-aggressive to the materials of the structure and working fluid. />
The type of climatic execution of the pump 2NVR-5DG Um 4 according to GOST 15150-69, but at the temperature of the surrounding air and the pumped out from 283 to 308 K (from plus 10s to plus 35s) . Requirements for the quality of electricity under GOST 13109-97. Vacuum plate-rut-rot 2NVR-5DG pump complies with the requirements of technical conditions TU 3648-006-00218526-2002
HACOC 2NVR-5DG is seasoned with the Vacma Oil 100 working fluid. Monitoring the level of working fluid through the oil designer, replenishment at the level of the working fluid below the minimum level of the oil indicator.The principle of operation of the plate-roting vacuum pump 2NVR-5DG Vacuum plate-roting NACOC 2NVR-5DG is a monolithic structure mounted on the central rack, on the one side of which the electric motor is attached, and on the other hand, the pump. Two supports with shock absorbers are attached to the rack. To transport the product in the upper part of the rack, there are two qm-bolt. Rotors and plate are located in the cylinders between the lids.
The rotor, plates, cylinder, front cover and middle lid form the first step, and the rotor, plates, cylinder, back cover and middle lid form the second step. The front cover, the cylinder of the first stage, the middle lid are attifted by four conical pins. The middle lid, the cylinder of the II step and the back cover are hidden by two conical excesses. The cylinders and lids are pulled out by bolts and studs and form a working unit, which is fixed to the pump body with bolt with seals. Each pair of plates in the rotors is pressed to the inner surface of the cylinders with springs. The rotation of rotation from the Rotor of the 1st stage to the rotor of the II stage is carried out by means of a key. The cavities of chambers I and II of the steps are connected sequentially, i.e. The compression cavity of the 1st stage is connected to the suction cavity of the LL stage. The tightness of the I and II steps is ensured by the seals and cuffs.
The shafts of the rotors rotate in the bearings of sliding pressed in the lids. The supply of the working fluid to the bearings is carried out through the channels, the supply of lubrication in the 1st stage is dosed by the jet. To ensure reliable tightness of the pump, an additional container formed by the lid and body is provided on its design.
The level of the working fluid is controlled by the oil indicator, the working fluid in the additional container serves, along with the cuffs, for additional sealing the output of the shaft. Dragging the working fluid from the pump and the intermediate cover is made with the holes in the housings with turned traffic with seals. The case is fixed to the lid with hairpins and nuts, and the lid, in turn, is fixed to the rack. On the I stage cylinder, a pipeline is installed, which is fixed to the housing with four M6 bolts using a uniform flange. A filter is installed inside the pipeline, which prevents the entry of solid particles into the pump. On the cylinders of both steps are exhaust valves. The valve of the I stage limits the limiter, and the valve of the II stage. The rotation from the electric motor to the pump is transmitted through the sleeve-fading coupling, consisting of half a machine and fan.
The cooling of the pump is forced, provided by the fan. The direction of air flow is condemned by a pallet. HACOC is also equipped with a device for dosed lubrication supply to the II stage cylinder and to prevent air and working fluid from entering the pumped volume when the pump stops.
The 2NVR-5DG pump device consists of the following main units and parts:

- According to the method of protecting a person from electric shock, the pump refers to electrical equipment of the 1st class according to GOST 12.2.007.0-75.
- The resistance of the insulation of the winding of the electric motor should be at least 0.5 MOM.
- Exceeding the temperature of the pump body operating at maximum residual pressure, a plus of 30 ° C, working fluid - plus 60 ° C can reach the temperature of the environment.
- When pumping vapors of water and steam -gas mixtures, it is recommended to install traps - sump (one from the side of the entrance and exit) for the collection of condensate, which can form in pipelines.
- A more frequent change in the working fluid is recommended if the pump works in conditions that cause rapid pollution and coking of the working fluid (dustiness, humidity).
- The first replacement of the working fluid should be carried out after 100 hours of the pump, and in the future after 2500 hours.
- The circuit breaker for the nominal current select 2.5A with an electromagnetic and thermal release that has a protection class - I according to GOST 12.2.007.0-75.
