Amsler Pendulum Dynamometer PM103

Click For Summary
SUMMARY

The forum discussion centers on issues with the Amsler Pendulum Dynamometer PM 103, specifically variations in loading rate and pendulum bouncing during operation. Users suggest that the problems may stem from blocked valves, which require cleaning. The original manual lacks crucial hydraulic drawings (103.009 and 103.010) necessary for maintenance, prompting a request for assistance in obtaining these drawings. A user named David Phillips offers help and provides contact information for further communication.

PREREQUISITES
  • Understanding of hydraulic systems and components
  • Familiarity with the Amsler Pendulum Dynamometer PM 103
  • Basic knowledge of maintenance procedures for tensile testing machines
  • Ability to interpret technical drawings and manuals
NEXT STEPS
  • Research the maintenance procedures for the Amsler Pendulum Dynamometer PM 103
  • Locate and obtain hydraulic drawings 103.009 and 103.010
  • Explore troubleshooting techniques for hydraulic systems in tensile testing machines
  • Contact Zwick or other labs for support and shared resources
USEFUL FOR

This discussion is beneficial for maintenance technicians, engineers, and laboratory personnel working with tensile testing machines, particularly those using the Amsler Pendulum Dynamometer PM 103.

Please help
We have an old Amsler Pendulum Dynamometer type PM 103 tensile testing machine which has been working admirably for many years - recently we started having problems with slight variations in loading rate and a tendency for the pendulum to bounce when loading is applied/removed abruptly. Reference to the manual suggests one or more of the valves may be blocked and needs to be stripped/cleaned. Unfortunately our manual is not complete and makes reference to two drawings, which have been lost (prior to our purchase of the machine), showing the location of the valves in question. The description of the maintenance procedure only refers to the valves and valve components by drawing numbers and as such is extremely difficult to follow without the drawings.

Can anyone help with supply of hydraulic drawings for the machine (or contact details for other labs operating similar machines) – our manual lists the drawings as 103.009 and 103.010 – general web search has proved fruitless.
