In the use of plate heat exchanger, sometimes we will encounter a problem, that is, sometimes the equipment will not feel hot, this time can be restored through the form of water discharge, but the operation of water discharge, is the need for everyone to correctly grasp, then the correct method of water discharge is what?
1, Find the distributor, generally inlet pipe on, outlet pipe in the lower.
2, You need to know the plate heat exchanger, the outlet pipe valve and the location of the small water pipe valve. Normal water discharge state is the total valve and outlet pipe parallel, small water valve and outlet pipe perpendicular.
3, Each sub-pipe should be drained, first shut the main valve, sub-pipe from left to right to start draining, sub-pipe small water valve does not move, small water valve to the right to twist 90 degrees, are shut off, only put the sub-pipe of water.
4, Next, in the plate heat exchanger vent, connected to the prepared plastic pipe, the vent on the small screw to the right to twist to start releasing water.
5, Just put out the water is very turbid, and the water temperature is low, put a few pots of water gradually become clearer, the temperature also gradually rise, with the hand can be clearly felt.
6, The end of the water pipe, the small water valve closed, began to put the following one, twist open the small water valve of the water pipe, in turn, put the water.
7, After the end of all, hand feel the water inlet pipe, the water temperature has risen significantly, at this time, open the main valve and all the small water valve, continue to release water until the temperature of the outlet pipe is satisfactory.
Therefore, the plate heat exchanger needs to be released by way of water, so that the equipment is hotter, however, pay attention to the correct method. When it is not hot, we should have to drain the water in time as a way to solve the problem.
