Plate frame heat exchanger parts assembly and equipment installation precautions

Plate frame heat exchanger parts assembly and equipment installation precautions

(Summary description)1. Pay attention to the center of gravity of the equipment when hoisting.
2. When bonding the gasket to the gasket groove, it should be ensured that there are no debris such as sand, oil, iron filings and flux on the gasket and in the gasket groove of the plate, so as not to damage the seal and cause leakage.

3. When tightening the bolts, the force should be uniform, and the distance between the inner sides of the two compression plates should be continuously measured to ensure that the deviation of the parallelism between the two compression plates is not greater than 3mm. Clamp to the specified size and achieve the corresponding parallelism to avoid the gasket pressing misaligned or slipped out of the gasket groove. At the same time, check carefully while clamping to observe whether there are any dislocations such as gaskets and plates.
4. The liquid for hydraulic test is generally water. The water temperature should not be lower than 5℃. The pressure should be raised slowly during the test. After the test is completed, properly loosen the compression nut to release the accumulated water, then tighten the nut and clamp it to the original size for use.
5. There should be a certain maintenance space around the plate frame heat exchanger, and its size is related to the size of the plate.
6. The clamping bolts should be coated with butter, and a protective tube should be covered when conditions permit to avoid rusting and bruising the threads.
7. If the maximum pressure of the pump outlet is greater than the maximum operating pressure of the equipment, a pressure reducing valve and a safety valve should be installed at the inlet of the equipment.
8. When the equipment is filled with liquid and under pressure, it is not allowed to clamp the nut.
