Hydraulic Jar Function Test requirements and procedure
 
 
Test Equipment Requirement :

  • One hydraulic pump: 5L/1Minute, work pressure should be above 20000PSI
  • 780KN Pulling delay mechanismAir compressor: Work pressure should be above 150PSI (1MPa).
  • Power, clamp, test caps, test pulling caps, pressure gauge, box spanner, pressure collection system and related high-handed pipe, sensor, computer, printer;

Function test

  • Tools function Testing
  • Time-Delay function Testing
  • a. Fill in special hydraulic oil from the oil filler plug in outer case, and bleed off from oil filler plug in splined case, observe that if there is no air bubbles bleed off from oil filler plug in splined case shows that the tool is full with hydraulic oil.
  • b. Attached the tool on the testing vise and start the pull time-delay testing. Pull off the tool in 10 times continuously and record the time-delay time, require that each time-delay time should less than previous, and the last time-delay time should be 1-2 minutes, the pull strength should be 222.2kN(50000lbs).
  • c. Time-delay adjusting

HSE Safety instructions:

  • When running each pressure test, you must increase pressure gradually. When the pressure is up to 30MPa, hold on for one minute, then every 10MPa keep it for one minute until the rating pressure;
  • During doing the pressure test, the tool should be placed in the test pit and cover the protecting board on the pressure test plug.
  • During the whole process, make sure the entire test operator keep away from plug and joint which may lapse.
  • Test area should set isolation, others except operator not allowed to enter test area.
  • If there is anybody in the test area, it should set isolation, avoiding test production fly off the test area.
