Application instructions for Plate-heat Exchanger
1. Before start the
machine, check the entire system for pipe connection and all connection form
that required for inlet and outlet for liquid. When start themachine, open the
low-temperature &low-pressure liquid valve first, and then open the
high-temperature &high-pressure liquid valve. When the machine stops
working, close the high-temperature & high-temperature & high-pressure
liquid valve first, and then, close the low-temperature & low-pressure
2. When the Plate-heat Exchanger is used for exchanging of liquid to liquid,
it need not to setup exhaust device; when exchanging from steam to liquid, a
reducing valve and a hydrophobic should be set in the pipe system as steam
temperature exceeds 1500C so as to increase the efficiency of heat-exchange and
prolong the life of the rubber gaskets.
3. After the Plate-heat Exchanger is operated continuously for a long time
and due to the sediment in the liquid gathering on the surface of the plates
which can increase heat resistance to debase the efficiency of heat diffusion,
therefore, the Plate-heat Exchanger should be maintained and cleaned
periodically, and the best bet is to install an anti-cleaning device on it.
Before disassembling and cleaning the machine, loose the fastening screws on the
cross first and then, take out the plates one by one to check and clean. The
installation of it must be operated according to the technical requirements and
the press of screwing down the bolts at both sides of the target plates must be
equal until have then to the specified dimension.
