THE CORE BALANCER GRAND “DBST-20” is a special hard bearing type of equipment .
The stand is used for a low-speed turbocharger cartridges balancing and is also used to check the assembled turbocharger for an oil leak. The machine was designed for a core balancing of internal combustion engines in their own middle housing in order to eliminate the technological unbalance that has arisen during assembly
Mainly used to eliminate the “technological” imbalance that occurs during the assembly of a turbocompressor cartridge. The presence of a hydraulic system with oil heating allows to simulate specific conditions during balancing and make sure if oil leakage is occurred.
This a bigger version of the Model DBST-10 , which our company has designed specially for large turbines with the weight up to 30 kg.
The rotation of the shaft on the stand is provided by the air system of the machine.
The stand has a high accuracy of determining the imbalance of the rotor (0.4 g ∙ mm / kg).

Design features of the machine
Design allows to connect cartridges of all types and all manufacturers to the hydraulic system of the machine using equipment supplied with the machine. The adapter for turbines with bottom oil supply, such as T5 VW TOUAREG 2,5 TDI, is included in a standard set.
Installation of the turbocharger casing on the mounting surfaces of the bearing housing with oil supply in journal bearings under operating pressure and temperature.
Free-standing oil tank 12 liters, no refilling of oil is required.
3-stage system of oil filtration allows to eliminate an unbalance directly on the machine by portable grinders. This procedure does not require to move the turbine cartridge from the machine.
Heating of oil up to 65 °C that allows to use inexpensive semi-synthetic brands.
Two plane measuring system “PAK-1”
Hardware-software balancing complex PAK 1 in two planes have a non-volatile memory and is carrying an unlimited number of settings running on the Windows operating system.
The system provides an imbalance measurement in two planes of the wheel relative to the geometric axis passing through the center of the hole.
Software-implemented built-in system functions:
Consideration of the initial imbalance when choosing the values of the control masses (a hint about the need to increase the control masses with significant values of the initial imbalance).
Control of rotor rotation speed with a hint if deviation from the nominal value is more than 5%.
Calculation of unit permissible masses and control weights necessary to adjust the balancing complex to a new rotor
Creation and printing of reports on rotor balancing
