Walker type/Kawai type high-temperature and high-pressure large chamber press (Multi Anvil Apparatus)

WalkerThe Kawai Multi Anvil pressure divider is currently the most widely used 6-8 type two-stage pressurized high-temperature and high-pressure device.

By using tungsten carbide anvil, ultra-high pressure exceeding 20GPa can be generated on the sample,>High temperature of 2000 ° C. The maximum sample pressure can exceed 50GPa.

Main features:

—Walker or Kawai Multi AnvilApparatus

—Sample temperature>2000 ° C, sample pressure>20GPa

—The maximum tonnage of the press is 1000-5000 tons

—Low pressure range, using traditional hydraulic system, high stability. Can drive the working piston to move quickly in the low-pressure range

—The pressure control in the high-pressure range is adjusted by a powerful servo motor, which can generate very steep or very flat pressure curves without vibration, avoiding pressure fluctuations in the hydraulic system.The maximum pressure error is+/-0.5 bar.

—The pressure is monitored and controlled through a control system (Siemens S7), which communicates with a computer via an RS-232 interface. The actual pressure value is measured by two high-precision digital pressure sensors installed on the pressure transmitter and working column, and transmitted to the control system..

—The control system can set up 20 segmented control programs, each of which sets the pressure and time separately, generates the pressure curve required by the user, and transmits the actual pressure and equipment status information to the computer. The control system adjusts the servo motor and adjusts the actual pressure to approach the set pressure.

—Due to the automatic control, only the servo motor regulates the pressure, the Max Voggenreiter high-temperature and high-pressure equipment has minimal noise and is very suitable for laboratory use. Long term use has shown that this control method has high stability and extremely low maintenance costs.
