What principles should be followed in the installation of spiral plate heat exchangers?
Murphy experts suggest that we should pay attention to the inspection and acceptance of the foundation quality before installing the equipment for replacing the spiral plate heat exchanger. Base elevation, plane position, shape and main size, and then whether the reserved hole meets the actual requirements; The position of the anchor bolt is correct, the thread is in good condition, the nut and washer are complete; Place the foundation surface of mat iron is smooth wait.
According to the form of spiral plate heat exchanger, enough space must be left at both ends of the heat exchanger to meet the requirements of cleaning and maintenance. The fixed head end of the helical plate heat exchanger should pay attention to leave enough space for the helical plate heat exchanger to extract the tube bundle from the shell.
There should be pad iron on both sides of the anchor bolt of the spiral plate heat exchanger. The installation of the pad iron should not interfere with the thermal expansion heat exchanger of the heat exchanger equipment. After it is in place, the level of the heat exchanger should be used to level the heat exchanger.
After leveling, the diagonal pad iron can be soldered to the base, but not to the bottom pad iron or slide plate. When installing two or more overlapping heat exchangers, it should be noted that the upper heat exchanger should be installed after the alignment of the lower heat exchanger is completed and the anchor bolts are fully fixed. For the heat exchanger can be removed before installing the core should be checked, clean, pay attention to the protection of the sealing surface and baffle plate.
When the tube bundles are moved and hoisted, they should be placed on a special supporting structure to avoid damage to the heat exchange tube. The mounting base of the helical plate heat exchanger must be satisfied so that the heat exchanger does not sink, or the pipe transfers excessive deformation to the heat exchanger pipe, and the foundation is securely connected with the helical plate heat exchanger through saddle supports with anchor bolts.
