We have a Bitzer 140 ton compressor Water has penetrated into it and the coil has burned The compressor is opened from the chiller When do evaporator tubes leak? When you don't have a suitable flow rate, for any reason, the filter is taken, the strainers are taken, or any other reason The first device that protects the chiller is the flow switch The second device that protects the chiller is low pressure switch, when the flow rate is not suitable, the suction pressure drops. In this case, various works have been done on the pressure switch and the sensitivity of the flow switch has also decreased A one-to-one quarter or one-inch joint is welded in this area And the flow switch connection is installed on it For safe installation, cut a 2-inch bushing in half and install it inside the pipe And with a conversion, install this connection on two inches Many times it happens that the blade that is inside this flow switch gets stuck to these welds on the side and causes the flow switch to get stuck in one position. The pump is off, but the flow switch shows the flow The facility maintainer may lower the sensitivity by manipulating the flow switch So, let's pay attention to a very simple matter, we will not suffer a loss of hundreds of millions
