OOO Oktyabrsky well logging equipment plant VNIIGIS (OOO OZKO VNIIGIS) together with Sauer-Danfoss specialists (Sauer-Danfoss, Germany, is a global major that designs, produces and sells hydraulic, electrical and switching system and components for use in mobile technology) developed a hydraulic drive, due to which began the production of WLTH with a hydraulic drive for various types of chassis. The production of OZKO VNIIGIS is certified up to ISO 9001 standard. 

 

 

 

Description

In this project is applied:

  • Sauer-Danfoss 90R100 axial piston hydraulic pump;
  • Sauer-Danfoss SNP gear pump;
  • Sauer-Danfoss H1-B-110 two-speed hydraulic motor;
  • Sauer-Danfoss PVG32 sectional proportional control valve;
  • pressure accumulator;
  • Argo-Hytos draining and suction filters;
  • safety valve, providing desired cable tension;
  • vertical and horizontal cylinders.

For all range of speed is used Fairfield global two-speed gear. The gear has four operational conditions:

  • high gear;
  • low gear;
  • brake unit;
  • neuter (free rotation in any direction).

 

 

 

 

 

 

 

The Sauer-Danfoss DP 260 display is used to display the present state of the system i.e. information on the charge circuit, spooling system, tension value, oil temperature, operating hours.

The speed control and direction of rotation of the winch is performed by Sauer-Danfoss MCH joystick.

 

 

 

 

 

 

 

 

 

The spooling system control and “shock-mounted position” of the vertical cylinder is performed by Sauer-Danfoss JS6000 joystick.

OOO OZKO VNIIGIS provides training of the staff for WLTH operation with a hydraulic drive. OZKO VNIIGIS carries out warranty and out of warranty service maintenance on a call-out basis notwithstanding center of location of WLTH.
