Description of the vacuum plate-roting pump 2NVR-250D Vacuum lacquin-rot-rot 2NR-250D pump is designed for pumping from sealed air vessels and explosion-stressed non-toxic non-toxic gases, vapors and steam-striped mixtures previously cleansed of drip overwhelming. and mechanical pollution, with the oxygen content, more than in the air (21 % in volume) under normal conditions, from atmospheric pressure to the maximum residual one, with pressure in the output cross section that does not exceed atmospheric more by 9.3 kPa (70 mm (70 mm rt.st.).
The type of climatic execution of the 2NVR-250D vacuum pump 4 according to GOST 15150-69, but at the temperature of the surrounding air and the pumped out the medium from 283 to 308 K (from plus 10C to plus 35C). Requirements for the quality of electricity under GOST 13109-97. Vacuum plate-rut-rot 2NR-250D pump complies with the requirements of technical conditions TU 3648-006-00218526-2002
HACOC 2NVR-250D 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-roting vacuum pump 2NVR-250D Vacuum pump 2NVR-250D have a block layout. At the rack mounted on OPOPAX bolts, on one side, an electric motor is installed over the lid, on the other hand, the pump pump, placed in the housing. The entrance and output of the pump are made in the rack. The input pipe is located on the upper wall of the rack, the exhaust pipe on the side wall of the rack.
Elements of maintenance of the pump are located from the end of the end and upper walls of the case, these include: The 2NVR-250D pump operating unit consists of two steps formed by cylinders, rotors, plates. The cylinders and lids are collected in the block on the pins and tightened with studs. The rotors rotate in rolling bearings. The vacuum NACOC 2NVR-250D is equipped with a gas-tank device designed to prevent vapor condensation when pumping steam-gas mixtures. The air consumption through the gas -radio device is installed due to the calibrated hole. The pump exhaust system consists of rubber valves, springs, lids, which simultaneously serve as limiters of the course of valves, oil -cutting screens. To prevent a solid particle in the input pipe, a filter is installed in the pump. Air cooling. Air fence is carried out through the cracks in the lid.
Advantages of the vacuum pump 2NVR-250D
Components of the vacuum pump 2NVR-250D
Operational characteristics of the vacuum pump 2NVR-250D
-
Holes for the bay and drain of the working fluid, closed, respectively, with traffic jams with seals
-
Observation glass for monitoring the level of working fluid;
-
A gas -tank device control handle.
- The 2NVR-250D vacuum pump provides for water cooling used when operating the pump at increased working pressure. The pipeline joins the water supply system using a coupling and countrogike. The consumption of cooling water should be at least 6 l/min. To reduce the flow rate in the working fluid when working at a pressure of 10 to 760 mm Hg.
- When working, it does not require maintenance, except for controlling the oil level
-
- Easily mounted in pumping systems
- The pumped out gas passes through the filter, which limits the release of oil vapor into the atmosphere.
- The foundation is not required
- On the basis of a vacuum plate-rot pump 2NVR-250D and a two-rot vacuum pump NVD-600, the AVD-150/63 unit is produced
- PecyPC before the first major overhaul of 12500 hours for 3 years, including the storage period of 1 year in the packaging of the manufacturer in storage rooms
- Warranty life - 12 months with warranty production not exceeding 2500 hours
- Oil separator 2MO-250
- 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 rated current select 12.5a with an electromagnetic and thermal release that has a protection class - I according to GOST 12.2.007.0-75.
- Sound pressure levels in octave frequency bands created by pumps at a distance of 1 m from their circuit should not exceed the values established by GOST 12.1.003-83
