Equipment Maintenance Guide #QR962C desktop reflow oven cannot heat up properly Inspection and Adjustment Methods<\/p>\n\n\n\n

Hey guys  this is Alex .<\/p>\n\n\n\n

Today we are going to share a customer case about QR962C desktop reflow oven .<\/p>\n\n\n\n

Client Description\uff1a<\/p>\n\n\n\n

after used 3 times , the oven stopped heating more than 190 degrees .<\/p>\n\n\n\n

The machine is not working . it does not warm over 150 degrees on any program . <\/p>\n\n\n\n

with forced heating, it reaches 180 .<\/p>\n\n\n\n

It isimpossible to exhaustive analyze the problem only based on the photos of the LCD display .<\/p>\n\n\n\n

So we asked the customer to take a video of the equipment surrounding and operation of the equipment.<\/p>\n\n\n\n

After a long long long…….download time from the google.<\/p>\n\n\n\n

You should know how difficult it is for us to use the google here in CN.<\/p>\n\n\n\n

So it would be much faster if you guys could send us a private youtube link .<\/p>\n\n\n\n

Of course, there is no problem with his operation after watching the video.<\/p>\n\n\n\n

However, we found the reason behind the machine: his exhaust pipe was set too long. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

the exhaust pipe is too long and the exhaust suction force is too large, <\/p>\n\n\n\n

the power of the machine is limited, the heat is drawn away, <\/p>\n\n\n\n

the temperature cannot go up during the high temperature time, <\/p>\n\n\n\n

and the low temperature is not obvious. <\/p>\n\n\n\n

The terminal of smoke exhaust should not be equipped with devices such as exhaust fans. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

We recommended that the length of the exhaust pipe is about 1.5 meters, <\/p>\n\n\n\n

and cannot exceed 2 meters. And no fix additional exhaust fan.<\/p>\n\n\n\n

If you have a similar problem and  not resolved .<\/p>\n\n\n\n

try to adjust\uff0c the problem would solved .<\/p>\n\n\n\n

OK thanks for your time <\/p>\n\n\n\n

have a nice day .<\/p>\n\n\n\n
