purpose of vaccume breaker in FWG ?

[@MoeMyintShein_MMU]

As a part to get fully enclosure. To break vacuum inside the shell after FWG stop. And also, can be used to adjust required vacuum % inside shell.

ကျွန်တော့်သင်္ဘောမှာ vacuume breaker ဖွင့်ပြီးရင် စောင့်နေရတယ် water line အောက် ​fwg ရောက်နေလို့ ရေပြန်ထွက်လာလို့ Bottom blow off ကလည်းမဖွင့်ဖြစ်ဘူး bilge တက်မှာစိုးတာနဲ့😬

Sir, good day! I have never worked with a "plate type" fresh water generator. but i have seen plate type heat exchanger. the sealing gasket is made of nitrile rubber. there are "telltale holes" given on gasket rubber sealing for each plate to identify leakage. Sir my question is : For plate type fresh water generator how to find out leakage procedure?

[@MoeMyintShein_MMU]

Normally, we carried out leakage test after maintenance. For Evaporator Side, Opens Jacket Water Valves and observes leakage between plates. For Condenser Side Testing, Need to blank off feed line to Evaporator by plate. After then, opens condenser valves, overboard valve and run ejector pump. Checks leakage between condenser plate. After satisfy leakage test, close the back shell cover. Do not forget to remove blind plate from evaporator feed line. 😊

sir, good day. can you plsease teach me, how can i check evaporator tube leaking or not? i can perform condenser tube leak test. but no idea about evaporator tube leak test.

Hi, Good Day MEC - Firstly, swing out evaporator housing with tubes nest after pipe connections (such as Jacket water in/out pipes, feed water inlet pipe and etc.,) to evaporator housing had been disconnected. After then, open the bottom end cover of evaporator housing. Carry out pressure testing one by one of each evaporator tube. Leakage tubes can be observed and investigated. Have a good day !!!
