VSR 400

VSR 400 Turbocharger Core-Balancing Machine

VSR 400 balancing machine
The Turbo Technics VSR 400 has been designed with the medium-to-large sized workshop in mind and has the capacity to balance up to 40 Centre Housing Rotating Assemblies (CHRAs) during a typical 8 hour shift. With a similar speed and phase measuring capability as the VSR 300, the primary benefit of the VSR 400 is the ability to carry out the balancing cuts in-situ without the need to remove the CHRA from the machine. Consequently, the cycle time between tests is significantly reduced thus minimising the time taken to balance each core. This is only possible because the VSR 400 uses an oil system with comprehensive 5-stage filtration to remove the swarf generated during each balancing cut. This high level of filtration is essential to maintain the integrity of the bearings during each test. Even the smallest particle of swarf re-entering the core in the lubricating oil, would rapidly compromise the core’s bearings.

As with the VSR 301, the operator retains total control of the speed of the CHRA throughout the test by means of a hand-operated air valve. As the test progresses the vibration level is displayed in real-time against the rotational speed. After each run, the operator locates any imbalance by positioning a cursor on the touch-screen display and reading the position from the clock-face on the display.

A hand-rest automatically moves in to position to assist the operator to make the balancing cut. This is made on the nose nut, using the integrated air cutter controlled by means of a foot switch. The test is repeated until the desired vibration limits are achieved. At the completion of the balancing process, excess oil is purged automatically from the CHRA.

The VSR 400 can be configured to use either the Turbo Technics’ standard range of slave turbine housings (as used with the VSR 301), or the long-throat range of slave turbine housings, which allows any turbo up to a maximum turbine wheel diameter of 85mm (3⅓”) to be balanced. It is not possible to switch between the 2 ranges of housings on the same machine.
