Helium mass spectrometer leak detector overview

 гелиевый масс-спектрометрический течеискатель Гелиот Вактрон

Vactron company represents Heliot helium mass spectrometer leak detector and provides services and maintenance training.

Heliot is a universal modern leak detector designed to implement all methods of mass spectrometry leak test in accordance with european standarts.

Key features of mass spectrometric leak detector

1) High pumping performance. The effective test port pumping speed is 5 l/s for helium. 
2) Tablet PC for wireless control and signal display is included in the standard package. 
3) Intuitive operation control via the high-resolution screen with fade resistance. 
4) Installation of oil-free scroll or oil rotary vane pumps of various speeds, according to customer requirements. 
5) Transport trolley to move the leak detector with a pump in the operating room. 
6) A simple periodic maintenance of the leak detector, which can be performed by employees of the enterprise after maintenance training. 
7) The device is economical to use. Consumables and spare parts always in stock. 
8) Hydrogen, as helium, can be used as the test gas. 

Application area:

  • verification of any industrial objects (vacuum chambers, tanks, pipes, valves, etc.), including processes with high and non-stable level of He-background
  • high-threading test of sealed products (seals, valves, housings of electronic devices, microelectronics)
  • integration into automatic lines with centralized management
  • solution of research tasks requiring non-standard algorithms for working with vacuum.

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.

Screw vacuum pumps

Features and Function

The screw vacuum pump is oil-free and exhausts means is a combination of two helical rotors with different directions of thread. Compressor housing and screws form a special form of the compression chamber for gas transportation.

Advantages of this type of pumps:

  • high pumping speed
  • the absence of oil vapors in the work area
  • limiting pressure below 10 -2 mm Hg
  • work on the atmospheric pressure
  • resistance to liquid and vapor content in the pumped medium.

Oil-free scroll fore pumps: 150-1000 l/min, 1 Pa.

The company Vactron represents scroll vacuum pumps - models GWSP150, GWSP300, GWSP600, GWSP1000, where the number shows the pumping speed of the pump in l / min. One means of obtaining oil-free vacuum, which are increasingly used in high-tech industries are "dry" vacuum pumps.

Currently, one of the key factors influencing the choice of means of evacuation is the purity of the residual medium. The absence of a working fluid vapor in the spectrum of residual gases is of fundamental importance in microelectronics, medicine, pharmacy and other areas of industrial production and science. Provide oil-free vacuum by using the "dry" pumping.

Two-stage rotary vane vacuum pumps

W2V05, W2V10, W2V20, W2V40, W2V60, W2V80, W2V100, W2V150, W2V180

Rotary vane pumps are widely used in vacuum technology and feature a robust design and ease of maintenance. The shortcoming of these pumps is the presence of oil vapor in the pumped region.

Pumping action rotary vane pumps is based on the change in the volume of cells formed eccentrically located rotor plates, body and end caps of the pump . The oil pump is used to seal the workinggap, the cooling of compressed gas and to reduce friction losses. The two-stage rotary vane oil pump provides pressure limit of 0.1 - 0.01 Pa.
