Vacuum plate-roting 2NVR-5DM1 is designed for pumping from hermetic air vessels and non -aggressive to the working fluid and materials of the design of explosive -fire -haired non -toxic gases, vapors and steam -gas mixtures pre -purified from drip moisture, and mechanical pollution, with an oxygen content no more than in air (21 % in volume) under normal conditions, from atmospheric pressure to the limiting pressure to the limit Residual, at a pressure in the output section not exceeding atmospheric more than 9.3 kPa (70 mm Hg). Vacuum pump 2NVR-5DM1 is made in the climatic design of UHL 4 according to GOST 15150-69, but for operation at ambient temperature and pumped out from 283 to 308 K (from plus 10 ° C to plus 35 ° C).
Vacuum lamellar-roting NACOC 2NVR-5DM1 is a volumetric machine with a drive connected through half a memba. The pump cooling system is air. The pump 2NVR-5DM1 pump is made of aluminum and aluminum alloys, a bronze metal sleeve. Requirements for the quality of electricity under GOST 32144-2013
HACOC 2NVR-5DM1 is seasoned with the working fluid Vacma Oil 100. Monitoring the level of working fluid through the oil indicator, replenishment at the level of the working fluid below the minimum level of the oil indicator.
The principle of operation of the plate-rot vacuum pump 2NVR-5DM1
When rotating the plates with springs pressed to the cylinder, gas absorbed through the input The pipe is supplanted through the exhaust valve due to periodic changes in the volume of the working chamber cavities.
The pump body 2NVR-5DM1 and the electric motor are attached to the rack. The case is simultaneously a container for filling the working fluid, which is designed to compact the working clearances of the rotor mechanism, exhaust valves I and LL steps and the grease of the rubbing surfaces. The working fluid is poured and drained through the holes in the case, covered with plugs and with a seal. The working fluid through the canal in the lid enters the cylinders, cuffs and bearings. The level of working fluid is controlled through the oil indicator. The pipe is attached on the case with a flange, and is compacted with a gasket. It also has a mesh filter.
The exhaust of the vacuum pump 2NVR-5DM1 is carried out through the fittings installed on the case, on the case. The pump has a plug of a gas -forly device, which is sealled by the seal, designed to prevent vapor condensation during pumping vapors and steam -gas mixtures. The cylinders assembled with lids form a working unit of two sequentially connected working chambers-speed chambers. The gas passes from the 1st stage to the second step through the bypass channel in the lid, which is compacted by the seal. The compressed gas sequentially passes both steps and is pushed through the valve, and with large input pressures - additionally through the valve of the 1st stage and then from the body through the fitting is thrown into the outlet for the highway. To the rotor of the 1st stage, the rotation is transmitted from the electric motor through the half-litter, the elastic sleeve-fracture of the half-linker with an elastic sleeve and a key. On the rotor of the II stage, rotation is transmitted through the key.
HACOC 2NVR-5DM1 is equipped with a centrifugal mechanism installed on the half-films and valves that automatically block The pipe in order to preserve the reached residual pressure in the pumped vessel, and also lets atmospheric air into the working chambers, preventing them with working fluid.
