Xray repair phsc

 Around 20 xray machine punjab need xray tube replacement ge and siemens I am not sure Xray tube became weak I suppose Xray tube cost one lakh bel Bangalore Ex factory price may be less My solution Order wooden xray table  Or change metal table top to wooden with sun mica sheet Remove xray grid  Remove bucky motor Remove aluminium cap xray tube Remove two fuses make single phase Repair cost around 10000/- Done at bhatinda long back ge xray My consultancy fee 10000/- Send demand draft 10000/- You verify the project fax it and bill it also add bypass xray control panel burnt input transformer and welding transformer reversed as ht transformer Mahesh n

Projects

 Did Phsc execute my projects Xray machine remove grid disengage Bucky motor remove aluminium cap on tube use wooden table and remove two fuses and make single phase Semiauto analyser fit computer connector or order analyser with filter wheel and stepper motor to select filter Ultrasound using both probes same time linear probe on back sector probe on front Both in straight line Ecg machine and monitor bypass Ecg preamplifier capacitive coupling to get varying amplitude Ecg And r wave only Ecg Defibrillator make voltage same value instead of joules lIke 20volt as 20joules Ac defibrillator also work? Ct scan make fan beam little long detector and not pencil beam and make single phase Fully auto analyser manually mix reagent and sample and do one test at a time Mri also make single phase fit exposure handswitch like x ray Test x ray ct mri with some suitcase or bag Computer fit ordinary dc fan on ic and fit two CMOS coin battery?
