The heat exchange unit is composed of a heat exchanger, a temperature control valve group, a trap valve group (when the heat medium is steam), a circulation pump, an electric control cabinet, a base, pipelines, valves, and meters.And can be installed with expansion tanks, water treatment equipment, pump frequency control, temperature control valve, remote communication control, so as to form a complete heat exchange station.The heat exchange unit has a standardized and modular design, complete configuration, convenient installation, high efficiency and energy saving. The heat exchange unit has the advantages of compact structure, reliable operation, simple and intuitive operation.The product is suitable for sanitary hot water in residences, institutions, factories and mines, hospitals, hotels, schools and other occasions. The integrated heat exchange unit can be used for both water-water exchange and steam-water exchange. What are the requirements for installing a heat exchange unit?
(1) Technical requirements for lifting. All rigging should be prepared.Large-scale heat-exchanging units have large lifting masses due to their large diameters and many heat-exchanging tubes. Therefore, the lifting bundle should be selected at the shell support with reinforced pads, and wooden blocks should be provided on both sides of the shell to maintain the shell to avoid shell body was destroyed by plastic deformation of the steel wire rope.
(2) The device size is biased towards requirements. Whether the partial size of the heat exchange unit can meet the requirements of the code.
(3) Requirements for support devices. One side of the movable support on the root bed should be embedded with a slide, and both sides of the anchor bolt should be provided with iron.
Before the equipment is leveled, the oblique horn can be welded firmly to the base plate, but it must not be welded to the flat horn or slide plate above, and the horn must be lubricated and leveled to ensure the free expansion of the movable support.
(4) Tightening of bolts. The fastening of the bolts of the heat exchange unit should be stopped at most three times, and the end points of each drive should be staggered 120 ° from each other. The tightening sequence is shown in the cycle diagram.
