DEFECT RECTIFICATION OF E-60,E-61 AND E-62 ONBOARD ICGS C-150

ENGINEERING

E-060 : AC compressor No.1 not developing oil pressure despite maintaining working oil level and making abnormal noise, suspect oil pump assembly defective. AC plant not getting tripped even after differential oil pressure is equal to suction pressure. Defect to be rectified and plant to be proved. In way job includes replacement of defective oil pump, oil strainer, valve reeds, and bearings. All consumables including compressor oil, refrigerant gas, nitrogen for pressure testing to be supplied by firm.(AC Compressor Make:- Cariyle, Model: 06DA537)

E-061 : AC compressor No. 02 making abnormal noise while running, not able to pump down the plant and is developing low lub oil pressure. Suspect reed mechanism, oil pump assembly including valve plate assembly defective. Same to be renewed and fitted post fitment of reed mechanism, valve plate assembly and lub oil pump assembly Plant to be vacuum and pressure tested and proved for satisfactory operation. (AC Compressor Make:- Cariyle, Model: 06DA537)

E-062 : Following Defects observed in AC system to be rectified:-(a) Temperature sensor pocket with thermometer to be fabricated on Discharge line of Ac compressor No. 1. (b) 12 angle valves are deteroited and leaking from gland same to be renewed as per sample.(c) Sea water interlock switch deteriorated/not working same to be replaced as per sample.(d) Oil separator of compressor no. 01 not working and continuously passing hot gasses to suction side resulting increase in discharge temperature. Suspect float valve of oil separator malfunctioning same to be repaired/ replaced(e) 02 in nos. Sea water valves not holding and deteriorated due to aging same to be replaced as per sample.
