Definitions
- the inventive invention is related to vacuum technology, and the more accurate is related to a vacuum pump of 5 composition.
- the main mechanism of gas pumping out of steam in the steam pump is the mode of operation of the steam generator and the mode of operation of the steam generator. Depending on the flow mode of steam, the steam pumps are divided into diffused, double pumps
- a diffuse vacuum pump is known (B.B. Zeitlin, "Vacuum Vacuum Canopies” 1965, “Energy”; (Moscow-Leningrad) str.259), containing a hermetic ⁇ -
- the coolers used in the indicated pump are:
- the unit there is a bath with working fluid and a heater, steam with nozzles, a cooling system for the cooler in the form of a cooler that is directly on the wall of the cooler. ⁇ in the event of an interruption in the cooling system, the unit may be replaced to ensure an increase in reliability
- a vapor vacuum pump (vv, ⁇ , 989168), similar to the above, is known, the internal drive at the outlet has been exposed to an increase in output
- ⁇ a ⁇ aya ⁇ ns ⁇ u ⁇ tsiya ⁇ usa ⁇ bes ⁇ echivae ⁇ d ⁇ lni ⁇ elny ⁇ d ⁇ g- ⁇ ev s ⁇ la on account ⁇ azheniya chas ⁇ i ene ⁇ gii ⁇ ⁇ iv ⁇ liney- n ⁇ y ⁇ ve ⁇ n ⁇ s ⁇ i, ch ⁇ ⁇ buslavlivae ⁇ b ⁇ lee vys ⁇ uyu s ⁇ - ⁇ s ⁇ is ⁇ echeniya s ⁇ ui of s ⁇ la, and sled ⁇ va ⁇ eln ⁇ , ⁇ vy-
- a traditional vacuum pump (HW, ⁇ , ⁇ 32 ⁇ 947) 9 is connected, which is equipped with a vertical mounted hermetic housing with a flange for connecting to the pump
- the South Indicated Cooling System of the pump is also insufficiently inefficient due to the insignificant contact of the cabinet with the lack of refrigeration.
- the use of a thermal network significantly increases the weight of the pump, which complicates the installation of the pump on a thermal installation of 5.

- Wi-Fi hardness in the system will reduce the thickness of the wall and, consequently, reduce the weight of the system.
- the thickness is divided, not only from the costs, but, more so, more so. ⁇ conditions of stability thickness ⁇ -
- the installation of the hard disk is not easy to use, it takes into account the thickness of the hard disk to take into account not the entire length of the cable, but only the distance between them. Well, for example, if ⁇ - pus is just nine of the ring of life,
- 35 vivks of the territory are concatenated parts that are contacted with the housings located in them and having a radius of curvature of life, which is essentially the same as the external radius of the circle. It brings ⁇ ⁇ 91/14102 ⁇ / ⁇ / 00039
- the proposed operating environment ensures that there are 20 acceptable angles on the surface of the casing and does not have a significant impact on life.
- Fig. 3 part of the housing, with discharges of harshness in comparison with a cylindrical housing and equal dimensions of the pumps;
- the normal vacuum pump contains a fully installed pressurized housing I (fig.) With flange 2, which is used to connect the housing of the pump I to the mains
- the unit is equipped with an integrated pump 4 with an empty height of 5 and an outlet for working fluid.
- ⁇ of the lower part of the chamber I was bathtub 6, filled with liquid and hard water,
- the option for the pump component is that the hydraulic function 8 makes a gap between the outside of the base unit 4,
- Cooling system of unit I was implemented as a winding on its wall in section 9 with units 10
- the casing of the casing I is fully equipped with the rescue gears, this ensures the minimum weight of the casing.
- the declared capacity of the device is generally only on the part of navigating the site 9 of the cooling system, and for other people of the room I have to pay for the site
- the operating version of the housing I is inactive, and at least the operating speed of the system is at a loss for the user to take part in the operation of the system.
- the proposed vacuum vacuum pump operates as follows.
- the dual part I (Fig. ⁇ ) of the pump by means of flange 2 is connected to the unit due to the fact that it is electrically operated. Then, to the outlet 3, the pump is started up and turned on, a vacuum pump is generated, which creates a pressure suitable for the operation of the vacuum pump. Then the cooling system is switched on, which ensures that the process unit 10 is used for the process of cooling and cooling the water in the unit 9 and the cooling unit.
- the mass of the body I of the pump can be reduced by 1.5 - 2.5 times.
- the proposed vacuum pump can be used with success for assembly and maintenance.
