Portable diagnostics kit
Portable diagnostics kit designed for diagnostics of technical condition of diesel engine’s main elements and for generation of advisory about the objects condition at its complex maintenance.

Portable diagnostics kit (PDK) for evaluation of technical condition (TC) of a diesel engine is a hardware-and-software suite used for diagnostics of technical condition of diesel engine’s main elements and for generation of advisory about the objects condition at its complex maintenance.

PDK performs the following tasks:

Evaluation of technical condition of diesel engine’s:

  • Separate cylinders of cylinder-piston-unit;
  • Fueling apparatus;
  • Gas-air line

Quality evaluation of:

  • dynamic adjustment;
  • fueling apparatus;
  • diesel oil

Main diagnostics tasks are implemented using modern suite of portable hardware controlled by software and methodical ware for periodic monitoring of the object’s technical condition.

Measurable range of parameters:

  • in-cylinder pressure of the working medium: 0-200 kg/cm2;
  • pressure of air and exhaust gases in the engine’s gas-air line: 0-2.5 kg/cm2;
  • temperatures: 0-8000C;
  • revolution rate: 0-2500 RPM;

Technical characteristics of the vibration measurer-analyzer with software:

  • measurable revolution rate from 10 to 20000 RPM;
  • measurable impulsive acceleration amplitude from 10 to 90 Db;
  • normal power supply of the device: 4.8V;
  • power consumption of the device: 250mA;
  • permissible ambient temperature 10-50 °C;
  • RS232 interface.
The kit includes the following hardware:
  • Ruggedized laptop (computing module);
  • Ruggedized tablet (diagnostic data gatherer);
  • Diagnostic kit
PDK performs the following general diagnostic tasks:

а) evaluation of technical condition of the primary diesel of a DG

  • Evaluation of technical condition of separate cylinders of the engine’s piston-cylinder unit and of fueling apparatus by results of analysis of indicative graphs;
  • evaluation of gas tightness of the running engine;
  • evaluation of metal content in the oil;
  • check of quality of alignment of the diesel and the generator in the shut-down DG;
  • evaluation of technical condition of generators’ bearings basing on vibration;
  • etc

b) evaluation of technical condition of the DG’s generator electric part:

  • check of condition of electric insulation;
  • check of absence of breakages and shorting in coils;
  • health check of adjustment system;
  • evaluation of wear of mechanical parts of automatic breakers;
  • check of condition of water cooling system;
  • etc
Portable diagnostics kit is designed to mount on ship`s diesel engines mainly but it can be used for other types of diesel engines as well
