Plate heat exchanger pipe how to connect and install?
Jul 16, 2016

When plate heat exchanger for heating the juice, heat exchangers, evaporation can be as close as possible to shorten the juice and juice steam pipe, reducing the temperature drop. Preferably before the heat exchanger into the valve juice as the juice evaporation tank valve to control (ie without heat exchanger control valve and the evaporator tank between), to avoid evaporation tank into the juice off a small valve in the heat exchanger even generate additional pressure within the water hammer phenomenon. Reducing the amount of juice in the feed at the same time when you want to turn down its inlet steam (or hot water) valve to avoid internal temperature and high pressure.

Plate heat exchanger tubing is connected to the appropriate treatment. To prevent pulling or thrust pipeline weight and thermal expansion and contraction in its connection flange, heat exchanger connection pipes should be installed 90 ° elbow. It should vent before inlet valves valve, before starting the water and dirt discharge pipe to prevent water hammer occurs when the boot and into the dirt. Material should be bypassed and the pipe valve, the lowest point to the bottom row of tubes. And should try hydraulic connector, with front opening on both sides of the channel, respectively, test pressure checks.

Each nozzle is connected thermometers and pressure gauges should be installed. When heated with steam, steam condensate water temperature should be only slightly lower than the temperature of the steam (saturated computing), if the decline is too large it indicates there is water inside the unit, which will significantly reduce its heat transfer performance. Heat exchanger should be equipped with a good steam condensate exclude devices.
