Plate heat exchanger shutdowns

  The detachable plate heat exchanger is made up of a plurality of stamped corrugated sheets at regular intervals, surrounded by gaskets, and Plate heat exchanger shutdownspressed by a frame and a compression screw.The four corner holes of the plate and the gasket form a fluid distribution pipe and a collecting pipe, and at the same time, the cold and hot fluids are reasonably separated to flow in the flow paths on both sides of each plate, and heat is performed through the plates. Exchange.What should you pay attention to when the plate heat exchanger is shut down?

(1) Before stopping the machine, the pump must be stopped and the power supply must be cut off.

(2) After stopping the pump, first slowly close the inlet of the heat medium and then close the inlet valve of the cold medium. Finally, the outlet valves of the two media are closed.

(3) If a vent valve is installed on the pipeline, it should be opened.

(4) For mediums with high temperature and corrosive media, the equipment should be emptied as much as possible to avoid scalding and corroding equipment when the equipment is opened.
