Vacuum booster Roots pumps

Twin-rotor pumps have the following features:

  • Fore pumps

  • Oil-free

  • Operate at an inlet pressure of from atmospheric pressure to 10 -2 Pa

  • Maintained at a pressure of 10 2 -10 Pa -1

  • Have the highest pumping speed for fore pumps

  • Require the use of an auxiliary pump for pre-vacuum

Pumps Roots perform work on the compression volume of pumped gas at counter rotating rotors with special profile ("eight") and have a great performance in the pressure range corresponding to the medium vacuum. Because of this, this type of pumps have proliferated title: mechanical vacuum booster. The principle of operation of the pump illustrated below. The rotors rotate synchronously in the housing towards one another with a high frequency that gives high performance oil-free pumping.

These pumps are used as the upper stages of the multistage pumping system for high performance vacuum in the range of 10-1 - 10-4 mm HgPumps Roots regardless of their design features require the creation on the output flange pre-dilution ("backing pump") sufficient to maintain the required pressure drop in the operating range. This problem is solved by means of auxiliary fore pumps, such as oil-free screw vacuum pumps .

Constructive solutions Roots pump series C, we can call strictly traditional, with particular emphasis on the quality of manufacturing and scrutiny at all stages of the process and production chain. All mechanical boosters series RNVB are 100% control on test rigs, including mechanical test, performance test and leak detection .

Components used in the construction of rotation - a classic reinforced bearings deep groove and angular contact ball bearings double. The movement of the motor is transmitted through the sleeve coupling with flexible insert.

To compensate for the large inertia arising in alternating operation START-STOP in cyclic operation, the nodes of the proposed rotation pumps applied increased (amplified) synchronizers and bearings.

RNVB pumps are one of the few of the Roots pump on the market, which are used in the design of helical timing gears. As a result, pumps RNVB have improved operational noise characteristics and high performance in terms of vibration when operating at nominal (maximum) revs. For example, the linear vibration velocity measured on the body model RNVB 25-20, weighing about a ton, is only 1.7-2.4 mm/c at 3000 revolutions per minute of the rotors.

Through the use of advanced and "solid" construction of the pump series RNVB optimum balance achieved, allowing to operate the equipment at relatively high temperatures up to 140 oC, and restricted flow of the cooling water - 2.4 L/min (or other liquid serving as coolant).

The housing material manufactured by casting from cast iron grades RF GG-40. Pump rotors are made of carbon steel St-45, followed by high-precision machining on five-axis machine tool CN and balancing on a computer stand.
