0.0/5 rating (0 votes)

Description

 
 
Specifications:
Programmable
Electric Hydraulic Pump
  • 208-240VAC, 50/60Hz (110V version is available via 500W transformer)
  • 180 W AC motor
  • Built-in digital pressure controller, which is 30 segments programmable to set up multi-pressure and dwell time during raising pressure. (Pressure settings have to be monotonically increasing. Multi-step pressure relief is not allowed.)
  • One pump speed controller is built in to adjust pump speed
  • One KF40 feed-through installed on the pipe, which allows the pipe is inserted into a glovebox and connect to press machine
  • RS485 port is built-in on the control panel for PC operation.
  • PC software based on Labview is available upon request at the extra cost.  ( You must inform us in advance if you need PC operation, and suggest you buy a laptop from us for pre-test )

  P = T x g x 10/ (πr^2)
    • P: pressure (Mpa) applied to your working piece
    • T: force (metric ton) applied to the pressure vessel cylinder
    • g: standard gravity. g ≈ 9.8 m/s2
    • π: ~3.14
    • r: radius (cm) of the pressure vessel (1.5 cm)
    • *1000 Kg = 1 Metric Ton; 1 Mpa = 10 Kg/cm2
 Pressure Accuracy
  • ±0.5MPa  in high pumping  speed    ±0.1 MPa  in low pumping speed
Operation Temperature
  • 10 - 40°C

Application Notes
  • The pressing die cannot be used for pressing powder with a particle size < 30 microns. Small particles may slip into the gap between pushing rod and steel sleeve and cause damages to the sleeve during the compression. Ball mill and sieve the powder and apply only the 32~75 microns powder to the pressing die to avoid the damages. Please consider using the 3'' Dia. Sieve Set No.200&450 Mesh to separate the 32~75 microns particles from the powder clumps. Please clean the mold via ethanol after the completion of each experiment
  • Do not raise the bottom cylinder (piston) more than its maximum traveling distance (25 mm)
  • The press can be put in a glovebox
              
  • Warning: Customers must always wear protective goggles during operation !!!
