Germany WILLE This high quality fully automatic testing system is designed and manufactured to perform one dimensional consolidation tests for large and X-Large specimen sizes. The loading systems are universal loading frame and are suitable for variety material testing applications and comes with variety of loading capacity from 200kN to5000kN.The system is modular and gives the possibility to customize the testing area, load, size of specimen and other technical specifications to reach the desired testing requirements.
Low friction Hydraulic with hydrostatic bearings mounted on crosshead is always covered with all its attachments to protect it against external influences. They are used at high pressures and produce large forces; and movement.Microprocessor-controlled consolidation test device includes a Load frame with integrated force, position and speed control for closed-loop control of strain- stress or displacement (position)and a high speed controller and data acquisition brings you different possibilities to use the device and run your test in a better way.
There are variety of cells with different options to meet all test requirement with different specimen sizes up to 500mm. GEOsys software in combination with other components performs all your tests automatically and without operator assistance during the test period.

The High-Pressure Consolidation and Borehole Simulation Test System is a newly developed apparatus designed for conducting laboratory experiments with measurement of mechanical and physical properties of large and hard samples like cemented soil samples. The testing equipment enables to perform a soil grouting procedure under geological stresses, drilling a bore in the sample, and simulate petroleum production processes.
All technical units which are subject to the fluid flow are made of high pressure bearing as well as chemically and temperature resistant materials, which enables utilization of brines and moderately aggressive crude oil components with high viscosity within a single experiment.
Hydraulic Power Pack
Our series of hydraulic power-packs supply smooth hydraulic fluid to actuators, hydraulic pressure intensifiers, and servo hydraulic testing machines to meet their testing system demands. As the dynamic performance of a hydraulic system depends on input oil flow and pressure in cylinder therefor we offer a wide range of flow rates to meet required dynamic performance for your application. All components are mounted conveniently for easy access.
A key feature of our hydraulic power packs is that they offer demand-dependent flow-rate control, delivering at a constant pressure of 210, 280 or 340 bar. They can locate beside or in greater distance from load frame. An oil-to-water heat exchanger or air-cooling exchanger controls fluid temperature. A temperature switch turns the hydraulic power pack off when the temperature of the fluid exceeds a pre-set value – lights on a front panel are used to indicate temperature levels. Closed loop re-cooler system (chiller for Oil /Water Cooling) is available on request and can be integrated to the unit.

indicators：Main switch、Emergency Stop、“Start”、“ON”(indicator light)、Reset、Manometer to operate pressures、Filter、Oil level (blinking)、Temperature (blinking)、Motor Temperature: The pump motor is overloaded、E-Stop: Illuminates after the emergency stop has been pressed
Air Cooling Method
Air cooling method uses a large fan which forces cooling air through the vanes of a radiator to reduce the temperature of hot oil quickly and efficiently. The hot oil is circulating in radiator to get cooler and gets working condition again. For large flow rate power pack, the fan generate larger amount of cooled air or it is recommended to use water cooling method.
Water Cooling Method
In this method a cooled water is reducing the temperature of oil to enable it to reach to working temperature condition. Depends on the flow rate of the power supply, the water flow rate be calculated correctly to give the good performance. The noise level of hydraulic supply units which use water cooling method is higher than Air cooled method. For example, the noise level of a hydraulic supply with flow rate of 7 LPM with water cooling method is 51dbwhich is super quiet while with air cooling is 62db (the values are measured in 1-meter distance form unit).
Consolidation Cells
The concept of the Oedometer test is to simulate in field condition of one-dimensional deformation of specimen and drainage condition.
In all oedometer cells, the soil specimen is cylindrical type which is placed in a confining ring which is made of stainless steel to prevent any lateral strain and provide a real one-dimensional test condition(the sample is allowed just to have vertical compress and swelling). Applied force is distributing over the entire of the specimen by using a pressure cap contacted to upper porous disc which is placed on top of the specimen. Two porous discs located at top and bottom of the specimen allow pore water to drain out of Specimen.
Mostly our cells are made completely of stainless steel and thanks to our variety range of the cells, all type of consolidation tests can be carried by usage of one of our listed cells.
High Pressure Large Consolidation Cell
This large consolidation cell is designed for the testing which requires high loads and high sample sizes. The cell is completely made of stainless steel.
Large Size Consolidation Cell
This large consolidation cell is designed to perform consolidation tests on large specimen sizes up to 500mm diameter size. It is manufactured from Stainless steel and is a load frame-based cell and is manufactured to run the test in combination with load frames with high capacity e.g. 250kN or 500kN.
Digital Controller
Digital High-Speed High Resolution Expandable Real Time Control and data acquisition System 10KHz control and data acquisition and 24 bit resolution. The Dynamic controller is suitable for screw driven instruments(electromechanical) , hydraulic instruments with a valve driven with ±10 Volt and variety of sensors e.g. load cells, LVDTs, strain gauges, extensometers, thermocouples and etc.
The multi-functionality of the controller allows a modular design of the measurement and control parameters (sensors) via intelligent sensor plug, which store the calibration parameters, thus depending on the application can be used flexibly.
